Amazon makes it remarkably easy to start selling. It makes it remarkably difficult to understand whether you are actually making money.
The Amazon seller who looks at their bank account and sees healthy deposits every two weeks may be profitable. Or they may be funding growth with capital they do not realize they are consuming. The difference between these two outcomes lives entirely in the accounting, and Amazon’s settlement structure is specifically designed to obscure it.
Every Amazon payout is a net number: gross sales minus FBA fees, referral fees, storage fees, advertising costs, returns, refunds, chargebacks, subscription fees, and any other Amazon-assessed charges for the period. When that single net number hits the bank account, the underlying economics of the business, the gross margin, the advertising efficiency, the true COGS, and the fulfillment cost per unit, have all been collapsed into a figure that tells the seller almost nothing useful about how the business is actually performing.
Add multi-state sales tax obligations triggered by Amazon’s FBA warehouse network, reimbursement tracking for Amazon’s inventory errors, and inventory valuation across multiple SKUs with different cost bases, and the accounting complexity of an Amazon business at meaningful scale is genuinely significant.
This guide covers everything Amazon sellers need to understand about their accounting requirements, which services handle it correctly in 2026, and how CoCountant supports Amazon sellers who need professional-grade financial oversight without the cost of an in-house accounting team.
Why Amazon Seller Accounting Is Uniquely Complex
The Settlement Report Problem
Amazon pays sellers every two weeks through a settlement report that consolidates every transaction, fee, and adjustment from the period into a single net payout. The settlement report itself contains the detail needed for correct accounting. The net deposit it produces does not.
What a single Amazon settlement report contains:
| Line Item | Accounting Treatment |
| Product sales (gross) | Revenue |
| Shipping revenue collected | Revenue (or pass-through) |
| Gift wrap revenue | Revenue |
| FBA fulfillment fees | Cost of revenue |
| Referral fees (8% to 15% of sale price) | Cost of revenue |
| FBA storage fees | Cost of revenue or operating expense |
| Advertising fees (Sponsored Products, Brands) | Marketing expense |
| Product returns | Revenue reversal + potential COGS adjustment |
| Refunds issued | Revenue reversal |
| Reimbursements (Amazon error claims) | Other income |
| Subscription fees (Professional plan) | Operating expense |
| Chargebacks | Revenue reversal + dispute fee |
| Net payout | NOT revenue |
A bookkeeper who records the net payout as revenue has produced an income statement where:
- Gross revenue is understated by the full amount of all fees deducted
- FBA fees, referral fees, and advertising costs are invisible as expense line items
- The gross margin calculation is meaningless
- Returns and refunds are not tracked as a distinct metric
The correct accounting processes every line item in the settlement report individually, not the net payout as a single entry.
The FBA Inventory Accounting Problem
Amazon FBA sellers do not control when their inventory moves or where Amazon stores it. Amazon distributes inventory across fulfillment centers in multiple states based on its own logistics algorithms. A seller who ships inventory to an Amazon fulfillment center in Tennessee may find that inventory distributed to fulfillment centers in California, New Jersey, Texas, and Washington within weeks.
This creates two distinct accounting challenges.
COGS timing: Inventory stored at Amazon is an asset on the balance sheet until it is sold. COGS is recognized when a unit is sold, not when inventory is shipped to Amazon. A bookkeeper who expenses inventory purchases when they are shipped to Amazon rather than when units are sold produces a COGS calculation that has no relationship to actual selling activity in the period.
Inventory valuation: A seller with 3,000 units of inventory across 15 FBA fulfillment centers and a warehouse needs to know the value of that inventory at any point in time. The balance sheet inventory figure must reflect: units on hand valued at the chosen COGS methodology (FIFO or weighted average), plus units in transit, minus units returned to inventory from refunds that are in resellable condition.
The Sales Tax Nexus Problem
Amazon’s FBA network is the source of one of the most significant compliance risks for Amazon sellers: physical nexus created in states where Amazon stores the seller’s inventory.
How Amazon FBA creates sales tax nexus:
When Amazon stores a seller’s inventory in a fulfillment center in a state, the seller typically has physical nexus in that state. Physical nexus predates the Wayfair economic nexus ruling and creates a sales tax obligation in every state where inventory is physically located, regardless of whether the seller has any employees, offices, or other presence there.
For an FBA seller whose inventory is distributed across 20 states by Amazon’s logistics network, this means potential sales tax registration and filing obligations in 20 states, most of which the seller never chose to operate in.
Amazon’s Marketplace Facilitator laws: As of 2026, all 45 states with sales tax have passed marketplace facilitator legislation requiring Amazon to collect and remit sales tax on behalf of third-party sellers for sales through the Amazon platform. This does not eliminate the seller’s nexus obligations entirely but significantly reduces the filing burden for platform sales.
What remains the seller’s responsibility:
- Sales tax on off-Amazon sales (own website, Shopify, wholesale)
- Registration in states where physical nexus exists
- Verification that Amazon is correctly remitting on sales through its platform
- State income tax obligations in states where the seller has nexus
The Reimbursement Tracking Problem
Amazon makes mistakes. FBA inventory is lost in fulfillment centers, damaged during handling, miscounted in inventory reconciliations, and occasionally disposed of without the seller’s authorization. When Amazon makes these errors, it owes the seller reimbursement for the affected inventory.
The process of identifying, claiming, and accounting for Amazon reimbursements is a distinct function that most general bookkeeping services ignore entirely.
Common Amazon reimbursement categories:
| Type | How It Arises | Value |
| Lost inventory | Amazon cannot locate units in their system | Unit sale price or COGS |
| Damaged inventory | Units damaged at FBA facility | Unit sale price or COGS |
| Customer return not received | Customer received refund but item not returned | Unit sale price |
| Incorrect weight/dimension charge | Amazon charged incorrect FBA fees | Fee overcharge amount |
| Inbound shipment discrepancies | Units shipped to Amazon but not received | Unit COGS |
Reimbursements received from Amazon appear in the settlement report as a line item. They must be recorded as other income in the accounting system, not as product revenue. The reimbursement income figure must reconcile to the amounts reported in Amazon Seller Central.
For sellers who have not been tracking reimbursements systematically, third-party reimbursement recovery services can identify unclaimed amounts from the past 18 months (Amazon’s reimbursement claim window). Sellers with significant FBA volume commonly recover $5,000 to $50,000 in unclaimed reimbursements per year.
The Advertising Cost Attribution Problem
Amazon Advertising (Sponsored Products, Sponsored Brands, Sponsored Display) is often the second or third largest cost category for an FBA seller after COGS and FBA fees. Amazon advertising costs appear in the settlement report as a deduction from the payout, but they should be tracked as a marketing expense separate from fulfillment and referral fees.
Why the separation matters:
A seller analyzing gross margin by ASIN needs to separate:
- COGS (the product cost)
- FBA fulfillment fees (per-unit fulfillment cost)
- Referral fees (Amazon’s sales commission)
- Advertising spend (marketing investment)
Pooling advertising with fulfillment fees produces a per-unit economics calculation that cannot distinguish the cost of selling from the cost of marketing. A product with excellent unit economics but high advertising spend looks the same on the income statement as a product with poor unit economics and no advertising, which are opposite business problems requiring opposite solutions.
The Amazon Seller Accounting Stack
A properly configured Amazon seller financial stack routes settlement data into the accounting system with the correct line-item separation.
| Layer | Tools | Purpose |
| Accounting platform | QuickBooks Online | Central financial record |
| Amazon settlement import | A2X, Finaloop, or Taxomate | Converts settlement reports into correct journal entries |
| Inventory management | Inventory Lab, Linnworks, or SellerApp | Tracks COGS and inventory across FBA and non-FBA locations |
| Sales tax | TaxJar or Avalara | Manages nexus tracking, collection, and filing |
| Reimbursements | Getida, SELLERBOARD, or manual review | Identifies and tracks Amazon reimbursement claims |
| PPC management | SellerApp, Helium 10 | Advertising performance tracking |
| Banking | Mercury or standard business checking | Receives Amazon payouts |
The bookkeeping service sits at the center of this stack, ensuring that journal entries from each integration land in the correct accounts, reconcile to source reports monthly, and produce financial statements that accurately reflect the economics of the Amazon business.
The 6 Best Accounting Services for Amazon Sellers in 2026
1. CoCountant: Best Overall for Amazon Sellers Needing Controller Oversight
Starting price: $160/mo
Platform: QuickBooks Online (client-owned)
Controller oversight: Every close, all plans
Published SLA: 2 to 4 hours standard
Close timeline: 10 to 15 business days
Amazon capabilities: Settlement report reconciliation, COGS and inventory accounting, FBA fee categorization, reimbursement income tracking, sales tax coordination
Best for: Amazon sellers who want verified financial statements, correct COGS accounting, and controller oversight alongside the platform expertise
CoCountant serves Amazon sellers with engagement configurations built around the specific data flows that Amazon selling creates. The settlement reconciliation process, the COGS and inventory setup, and the sales tax coordination are all addressed during onboarding before the first monthly close begins.
What the CoCountant engagement includes for Amazon sellers:
Every Amazon payout is reconciled to the corresponding settlement report, with gross revenue, FBA fees, referral fees, advertising costs, returns, and reimbursements recorded as separate line items in the chart of accounts. The integration tool of choice (A2X for most FBA sellers, or a structured manual process for lower-volume sellers) is configured during onboarding and tested against a sample settlement period before going live.
Inventory is correctly recorded as a balance sheet asset, not an immediate expense. COGS is recognized per unit sold based on the chosen inventory methodology. The inventory balance is reconciled to the Amazon Seller Central inventory report at each monthly close.
The controller reviews and signs off on every close before reports reach the client. For an Amazon seller where settlement reconciliation errors can accumulate systematically across every two-week payout cycle, the independent controller review is the quality mechanism that catches those errors before they compound into material misstatements.
Plans: Launch $160 to $235/mo | Scale $540 to $940/mo | Command $1,270 to $1,990/mo
Ratings: 4.3/5 Trustpilot | 5/5 Clutch | 5/5 G2
2. Finaloop: Best for Amazon and Shopify DTC Brands Wanting AI-Native Bookkeeping
Starting price: $245 to $415/mo (Core, revenue-based)
Platform: Proprietary (Rico AI engine)
Controller oversight: Not published as standard
Published SLA: None
Amazon capabilities: Multi-channel including Amazon, Shopify, eBay, TikTok Shop Best for: DTC brands selling primarily through Amazon and Shopify who want maximum automation
Finaloop is purpose-built for multi-channel ecommerce and handles Amazon’s settlement complexity through its proprietary Rico AI engine, which automates approximately 94% of transactions including COGS, inventory, and multi-channel revenue separation.
Strengths:
- Purpose-built for ecommerce, handles Amazon specifically
- 5.0/5 Shopify App Store (1,860+ reviews)
- Real-time financial dashboard rather than month-end close
- Strong multi-channel reconciliation across Amazon and Shopify simultaneously
- Handles COGS and inventory automatically
Limitations:
- Proprietary platform with no QuickBooks export (data portability risk)
- Revenue-based pricing escalates as Amazon sales grow
- No published response SLA
- Controller oversight not published as standard
- Not suitable for service businesses or non-ecommerce entities
- Limited customization when automation produces incorrect results
Verdict: The strongest pure-play Amazon and Shopify bookkeeping option for sellers who prioritize automation and real-time visibility and accept the proprietary platform trade-off.
3. Xendoo: Best for High-Volume Amazon Sellers Needing Weekly Cadence
Starting price: $355/mo (Essential)
Platform: QuickBooks Online or Xero
Controller oversight: Not published as standard
Published SLA: None
Amazon capabilities: Amazon, Shopify, Etsy, eBay, Walmart integrations
Best for: Multi-channel Amazon sellers with high transaction volume who need more frequent than monthly financial visibility
Xendoo’s weekly bookkeeping cadence is its primary differentiator for high-volume Amazon sellers. A seller processing thousands of orders per month across multiple channels benefits from weekly reconciliation cadence more than a monthly-only service because errors in the settlement import are caught within days rather than accumulating for a full month.
Strengths:
- Weekly bookkeeping cadence
- Client-owned QuickBooks or Xero account
- Amazon and multi-channel integrations
- 30-day money-back guarantee
- 4.8/5 Birdeye rating (177 reviews)
Limitations:
- $355/mo entry is higher than CoCountant’s $160/mo
- No published response SLA
- No controller oversight as published standard
- No CFO or FP&A services
4. A2X: Best Settlement Reconciliation Tool for Amazon Sellers Using Any Bookkeeper
Starting price: $29 to $249/mo (scales with Amazon orders)
Platform: Works with QuickBooks Online or Xero
Type: Software integration tool, not a managed bookkeeping service
Amazon capabilities: Amazon Seller Central settlement reconciliation
Best for: Any Amazon seller whose existing bookkeeper needs better settlement data processing
A2X is the industry-standard tool for converting Amazon’s complex settlement reports into clean, accountant-prepared journal entries in QuickBooks or Xero. It is used by professional ecommerce bookkeepers, including CoCountant, as the integration layer between Amazon Seller Central and the accounting platform.
What A2X does:
- Processes Amazon settlement reports automatically when they close every two weeks
- Separates gross sales, FBA fees, referral fees, refunds, reimbursements, and advertising into distinct journal entry lines
- Maps each category to the correct QuickBooks or Xero account based on configured account mapping
- Produces a journal entry that reconciles exactly to the Amazon payout amount
Why it belongs on this list: Any Amazon seller whose bookkeeper is recording net deposits rather than using A2X or an equivalent tool has a bookkeeper who is producing systematically incorrect financial statements. Understanding A2X as the tool that enables correct Amazon accounting helps sellers evaluate whether their current bookkeeping service is using it.
Limitation: A2X is a tool, not a service. It still requires a bookkeeper or accountant to configure the account mapping correctly, review the output monthly, and ensure the journal entries reconcile to the actual financial records.
5. Bookkeeper360: Best for Amazon Sellers Wanting Tax Preparation Bundled
Starting price: $399/mo (Core)
Platform: QuickBooks Online or Xero
Controller oversight: Not published as standard
Published SLA: None
Amazon capabilities: Through QuickBooks integrations
Best for: Amazon sellers who want bookkeeping and tax preparation from one vendor
For an Amazon seller with multi-state sales tax obligations and an annual income tax filing, Bookkeeper360’s all-in-one model that combines bookkeeping and tax preparation in a single engagement reduces the coordination overhead of managing separate vendors.
Limitations for Amazon sellers: Bookkeeper360 does not publish Amazon-specific settlement reconciliation capabilities as a distinct service feature. The quality of their Amazon accounting depends on whether the specific bookkeeper assigned to the account has configured A2X or a comparable tool correctly. At $399/mo, the entry price is more than double CoCountant’s $160/mo.
6. inDinero: Best for Multi-Entity Amazon and Retail Operations
Starting price: $300/mo (Essential)
Platform: QuickBooks Online and NetSuite
Controller oversight: Not published as standard on entry tier
Published SLA: None
Best for: Amazon sellers who have grown into multi-entity structures or retail operations requiring NetSuite
For an Amazon seller who has grown to include a wholesale entity, a retail brand entity, and international operations, inDinero’s multi-entity consolidation capabilities provide accounting depth that ecommerce-specialized services do not offer.

COGS and Inventory: Getting It Right From Day One
The COGS calculation is the foundation of every profitability metric an Amazon seller needs to manage the business. Getting it wrong from the start creates financial statements that are confidently misleading.
Step 1: Choose and Document the Inventory Accounting Method
FIFO (First In, First Out): Assumes units are sold in the order they were purchased. The cost of the oldest units is applied to COGS first. In an environment of rising costs (inflation, supply chain disruptions), FIFO produces lower COGS and higher reported gross margin than weighted average.
Weighted Average Cost: Calculates a running average cost per unit that blends all purchase prices. When new inventory is purchased at a different cost, the average updates. COGS per unit is the current weighted average at the time of sale.
The practical choice for most Amazon sellers: Weighted average cost is simpler to maintain, particularly for sellers who purchase inventory in multiple batches at varying prices. FIFO requires tracking individual lot costs and applying them in sequence, which is manageable with inventory management software but more complex to verify manually.
Document the choice: The inventory accounting methodology must be applied consistently across periods. Changing methods without disclosure is an accounting policy change that affects the comparability of financial statements.
Step 2: Configure the Chart of Accounts for Amazon-Specific COGS
For an Amazon seller, the COGS section of the chart of accounts should include:
- Product cost (inventory COGS): The actual per-unit cost of goods sold
- FBA fulfillment fees: Amazon’s per-unit fulfillment charge
- Referral fees: Amazon’s commission on each sale
- Inbound shipping to FBA: Freight costs to deliver inventory to Amazon fulfillment centers
- Packaging and prep costs: If the seller preps inventory before shipping to FBA
This structure produces a gross margin calculation that reflects the true cost of selling each unit through Amazon, not just the product cost alone.
Step 3: Reconcile Inventory Monthly
The inventory balance on the balance sheet must reconcile to Amazon Seller Central’s inventory report at each monthly close. Common reconciling items include:
- Units in transit (shipped to Amazon but not yet received)
- Stranded inventory (Amazon has units but they are not listed)
- Units in reserved status (pending customer return)
- Unfulfillable inventory (damaged units Amazon will not fulfill)
A controller reviewing the monthly close confirms that the inventory balance reconciles to the Amazon inventory report and that any reconciling items are identified and explained.
Amazon Sales Tax: What Sellers Must Manage in 2026
Marketplace Facilitator Coverage
As of 2026, Amazon collects and remits sales tax on behalf of third-party sellers for all sales through the Amazon marketplace in all 45 states with sales tax. This means Amazon-platform sales do not require the seller to collect or remit state sales tax for those specific transactions.
What this does not cover:
- Sales through the seller’s own website or Shopify store
- Wholesale sales to retailers
- Any state income tax obligations (separate from sales tax)
- Registration requirements in states where the seller has physical nexus
Physical Nexus From FBA Warehouses
Amazon’s distribution of FBA inventory across its fulfillment network creates physical nexus in states where the inventory is stored. Even if Amazon is collecting and remitting sales tax on marketplace sales, the seller still has registration obligations in each nexus state.
The registration obligation matters for:
- Filing requirements (even zero-dollar returns may be required)
- State income or franchise tax filings triggered by physical nexus
- Wholesale sales made directly to retailers in those states
Managing Sales Tax in the Books
Sales tax collected by Amazon on the seller’s behalf must be tracked but does not appear in the seller’s revenue. It flows through Amazon’s settlement system. The bookkeeping records for sales tax focus on:
- Off-Amazon sales tax collected and recorded as a Sales Tax Payable liability
- Sales tax remittances recorded as reductions of the liability
- Verification that the liability balance reconciles to amounts owed
CoCountant’s tax advisory services provide the coordination between the accounting records and the tax compliance function, ensuring that sales tax obligations are tracked correctly and that the seller’s nexus exposure is properly addressed.
Reimbursement Accounting: The Revenue Stream Most Sellers Ignore
Amazon reimbursements represent a distinct income category that appears in settlement reports but is frequently not tracked as a meaningful business metric.
How Reimbursements Should Be Accounted For
When Amazon reimburses a seller for lost or damaged inventory, the correct accounting treatment depends on whether the seller previously recorded the inventory as COGS (meaning it was treated as sold when it was actually lost or damaged):
If inventory was written off or COGS recorded for lost units: The reimbursement received recovers a previously recorded loss. Record as Other Income.
If inventory was still on the balance sheet as an asset when lost: The reimbursement replaces the asset value. Record as Other Income to match the inventory write-down.
Reimbursements should never be recorded as product revenue. Pooling reimbursement income with sales revenue overstates the gross revenue figure and distorts every sales-based metric.
Proactive Reimbursement Tracking
A monthly reconciliation of Amazon’s inventory activity report against the accounting system’s inventory balance will identify:
- Units Amazon shows as lost that have not yet been reimbursed
- Units Amazon reimbursed that were recorded incorrectly
- Discrepancies between Amazon’s COGS-basis reimbursement calculation and the seller’s actual unit cost
For sellers with significant FBA volume, proactive reimbursement tracking rather than passive acceptance of whatever Amazon reimburses unsolicited is a meaningful revenue recovery exercise.
What to Look for in an Amazon Seller Accounting Service
1. How do you process Amazon settlement reports? The answer must describe either A2X, Finaloop, or a specific manual process that separates gross revenue, FBA fees, referral fees, advertising costs, refunds, and reimbursements into distinct accounting entries. “We reconcile the Amazon deposits” is not an adequate answer.
2. How is COGS calculated for FBA inventory? The answer must describe the inventory accounting methodology, confirm that inventory purchases are capitalized as assets rather than immediately expensed, and explain how COGS is recognized per unit sold.
3. How do you handle Amazon reimbursements in the books? The answer must confirm that reimbursements are recorded as other income, not product revenue, and that the reimbursement income reconciles to Amazon’s settlement data.
4. How do you coordinate on sales tax nexus from FBA warehouses? The answer must acknowledge the nexus issue, describe how off-Amazon sales tax is tracked as a liability, and explain the coordination process with the seller’s sales tax software or advisor.
5. Does a controller review the close before reports reach me? For an Amazon seller where settlement reconciliation errors can be systematic and compound across every payout cycle, the controller review that catches those errors before the financial statements are used for any decision is the quality mechanism that makes the records trustworthy.
For a broader evaluation of what distinguishes the best ecommerce bookkeeping services on the dimensions that matter for Amazon and multi-channel sellers, our guide to best bookkeeping services for ecommerce businesses in 2026 covers the full comparison with specific recommendations by seller type.
Common Amazon Seller Accounting Mistakes and Their Cost
Mistake 1: Recording net Amazon payouts as gross revenue. Every settlement-period’s gross sales, FBA fees, referral fees, and advertising costs are collapsed into a single deposit. The income statement has no cost structure. Gross margin is uncomputable. This is the single most common Amazon accounting error.
Mistake 2: Expensing inventory purchases as they are shipped to Amazon. $50,000 of inventory shipped to Amazon in January shows as a $50,000 expense in January. The income statement shows a loss in January and inflated profit in every month inventory sells. COGS has no relationship to units sold.
Mistake 3: Not tracking reimbursements separately from product revenue. Amazon reimbursements pooled with product revenue inflate the gross revenue figure and distort every sales metric. When the seller or their accountant tries to analyze revenue trends, reimbursement variability creates noise that obscures actual sales performance.
Mistake 4: Missing multi-state sales tax obligations. An FBA seller whose inventory is distributed to fulfillment centers in 15 states who has only registered in their home state has 14 states of accumulated sales tax exposure. The liability grows silently until a state contacts the seller, at which point the back taxes, interest, and penalties can be significant.
Mistake 5: Not reconciling settlement reports to the accounting system. A bookkeeper who does not verify that the journal entries in QuickBooks reconcile to the actual Amazon settlement report has no way of knowing whether the integration is working correctly. Systematic mapping errors accumulate month over month.
Mistake 6: Pooling advertising spend with FBA fulfillment fees. Marketing spend and fulfillment costs are different business levers. Pooling them produces an undifferentiated cost line that cannot inform decisions about advertising efficiency or fulfillment cost reduction.

How CoCountant Serves Amazon Sellers
CoCountant’s bookkeeping services for Amazon sellers are configured from onboarding around the specific data flows, revenue model, and compliance requirements of each seller’s operation.
Settlement reconciliation: Every Amazon settlement period is reconciled to the settlement report, with gross revenue, FBA fees, referral fees, advertising costs, returns, and reimbursements recorded as separate line items in the chart of accounts. The A2X integration or structured import process is configured during onboarding and tested against a sample settlement before the engagement goes live.
COGS and inventory: The inventory accounting methodology is documented and configured during onboarding. Inventory purchases are correctly capitalized as assets. COGS is recognized per unit sold based on the chosen methodology. The inventory balance is reconciled to Amazon Seller Central’s inventory report at each monthly close.
Reimbursement tracking: Reimbursement income received from Amazon is recorded as other income and reconciled to the settlement data. Discrepancies between expected and received reimbursements are flagged for the client’s reimbursement recovery follow-up.
Sales tax coordination: Off-Amazon sales tax is recorded as a Sales Tax Payable liability in the chart of accounts and reconciled to TaxJar, Avalara, or the seller’s chosen sales tax platform at each close. CoCountant coordinates with the seller’s sales tax advisor on nexus management.
Controller oversight: Every close is reviewed and signed off by a controller before reports reach the client. The controller confirms that every settlement period reconciles to source reports, that the COGS calculation reflects actual units sold, and that the financial statements accurately represent the Amazon business’s performance.
Plans are flat-rate and published on the pricing page, starting at $160 per month with no setup fees and no annual lock-in. For Amazon sellers who want to understand exactly how an engagement would be structured for their specific platform mix and revenue stage, contact us for a direct conversation.
Conclusion
Amazon seller accounting is not a complexity tier above general small business bookkeeping. It is a different kind of accounting with specific requirements that general bookkeeping services consistently fail to meet.
Settlement reconciliation that separates gross revenue from fees at the line-item level. COGS accounting that recognizes product cost at the point of sale, not at the point of purchase. Inventory that reconciles to Seller Central at every close. Reimbursement income that is tracked as a distinct category. Sales tax nexus that is managed proactively rather than discovered reactively when a state sends a notice. The Amazon sellers who understand their actual unit economics, know their real gross margin, and have compliance obligations documented and current are the ones whose businesses scale without the financial surprises that derail growth. That clarity comes from accounting records that are configured correctly for how Amazon selling actually works, maintained with the discipline of monthly reconciliation, and verified by a controller who reviews the close before the numbers are trusted.
FAQs
What accounting services are best for Amazon sellers?
The best accounting services for Amazon sellers combine Amazon settlement report reconciliation using tools like A2X or equivalent, COGS accounting that recognizes costs at the point of sale rather than at purchase, inventory balance reconciliation to Amazon Seller Central, reimbursement income tracking, and controller oversight on every close. CoCountant provides all of these starting at $160 per month with a published 2 to 4 hour response SLA. Finaloop is the strongest alternative for DTC brands accepting a proprietary platform.
How do Amazon FBA sellers handle COGS accounting?
Amazon FBA sellers should record inventory purchases as balance sheet assets, not immediate expenses. Cost of goods sold is recognized when units are sold, calculated as units sold multiplied by the per-unit cost under the chosen inventory methodology (FIFO or weighted average). The COGS account in the chart of accounts is separate from FBA fulfillment fees and referral fees, which are also per-unit costs but categorized as cost of revenue rather than product COGS.
Do Amazon sellers need to collect and remit sales tax in 2026?
As of 2026, Amazon collects and remits sales tax on behalf of third-party sellers for all sales through the Amazon platform in all 45 states with sales tax. However, Amazon FBA sellers likely have physical nexus in states where Amazon stores their inventory, creating registration requirements and potential state income tax obligations. Off-Amazon sales (Shopify, wholesale, own website) require the seller to collect and remit sales tax independently based on their nexus profile.
What is the best tool for Amazon settlement reconciliation?
A2X is the most widely used professional tool for converting Amazon settlement reports into accountant-prepared journal entries in QuickBooks Online or Xero. It separates gross sales, FBA fees, referral fees, advertising costs, refunds, and reimbursements into distinct accounting entries and reconciles them to the net payout amount. For DTC brands with both Amazon and Shopify sales, Finaloop’s AI-native approach handles both channels in an integrated system, though on a proprietary platform.
How should Amazon reimbursements be recorded in the books?
Amazon reimbursements for lost or damaged inventory should be recorded as other income, not as product revenue. Pooling reimbursements with sales revenue overstates gross revenue and distorts every sales metric. The reimbursement income should reconcile to the corresponding settlement report line items, and any discrepancy between expected and received reimbursements should be tracked for potential recovery claims.
