Amazon FBA Bookkeeping: How to Record Sales, Fees, Inventory, and Payouts Correctly
Most Amazon sellers celebrate when that payout hits their bank account. And honestly, fair enough. But here is the problem: that number is not your revenue. It never was. Amazon has already quietly deducted its fees, subtracted refunds, held back reserves, and adjusted for taxes before sending you what is left. You are looking at the end result of a dozen transactions bundled into one tidy figure. Book it as income and your books are wrong from the very first entry.
Amazon FBA bookkeeping is the process of recording the gross activity sitting behind Amazon’s net payouts. The job is to pull the right data from Seller Central, classify every transaction correctly: sales, refunds, referral fees, FBA fees, taxes, reimbursements and then reconcile everything to your bank deposit and your financial statements.
Get this right and your books give you a real P&L, an honest balance sheet, genuine cash flow visibility, and records that are ready for the IRS or the CRA when tax season arrives. Get it wrong and every month makes the problem slightly worse, until the whole thing unravels at the worst possible time.
This guide walks through everything: which reports matter, how settlements actually work, how to categorise fees and track inventory, how to choose between cash and accrual, and how to close your books every single month without leaving gaps.
What Is Amazon FBA Bookkeeping, and Why Is It Different from Regular Small-Business Bookkeeping?
Amazon FBA bookkeeping is the process of recording Amazon sales, refunds, fees, taxes, inventory movements, and payout activity into accurate books. In principle it is the same as any bookkeeping. In practice it is considerably harder, and the reason is Amazon’s payout structure.
Bookkeeping vs. Accounting: What This Page Covers
Bookkeeping is the recording layer that means capturing every transaction correctly so the ledger stays clean. Accounting is the analysis layer: reading those records to produce financial statements, make decisions, and prepare taxes. This guide focuses on getting the recording right. If the bookkeeping is wrong, everything built on top of it : the P&L, the tax filing, the business decisions : will be wrong too.
Why Net Payouts Create Bookkeeping Errors
Every Amazon settlement is already a net figure by the time it reaches your bank. Gross sales have been reduced by FBA fees, storage fees, refunds, promotional discounts, and taxes. A reserve may have been withheld. A reimbursement may have been added. None of that is visible unless you pull the Payments Report or Settlement Report from Seller Central. Booking the deposit without doing that is the single most common bookkeeping mistake FBA sellers make.
The rule every FBA seller needs to follow: Never book an Amazon deposit as revenue. Pull the settlement report first, break it into its components, and then post each component to the correct account.
What Clean Books Should Produce
Good Amazon FBA bookkeeping is not about compliance for its own sake. The real payoff is:
- A real P&L: True revenue, actual expenses, and an honest margin : not inflated by fees that were never recorded
- An accurate balance sheet: Correct inventory valuation, outstanding Amazon reserves, and real liabilities
- Real cash flow: Where money is actually coming from and going, especially when inventory purchases are large
- Margin visibility: Product level profitability so you know which SKUs are actually worth scaling
Which Amazon Reports Matter Most for Bookkeeping?
The core source records for Amazon FBA bookkeeping are the Payments Report, the Payment Date Range Transaction Report, the Inventory Ledger, the Fee Preview, and the Marketplace Tax Collection Report. Everything else is secondary. Here is what each one does and when to use it.

The Month-End Close: Why It Matters
Month-end close isn’t data entry—it’s quality control. Closing the books each month catches errors before they compound and prevents the tax-season scramble that happens when 12 months of transactions need untangling at once.Transaction Review
Every recorded entry is reviewed for accuracy. Miscategorized expenses are corrected, and missing transactions are identified via bank reconciliation.Variance Analysis
Revenue and expenses are compared to prior months and budgets. Unusual variances are investigated and resolved before becoming audit issues.Adjusting Entries
Accruals for unbilled expenses, allocation of prepaid costs, and depreciation for fixed assets are recorded to reflect true performance.Period Lock
The month is “closed” in the accounting software, preventing accidental historical changes and creating a clean audit trail.Benefits of Consistent Month-End Close
How Do Amazon Settlements and Payouts Actually Work in Books?
An Amazon payout is not revenue. It is a net transfer built from gross sales, refunds, Amazon fees, taxes, reserves, and other adjustments sitting inside one number. Booking it as sales income creates a fundamental error in your books and one that quietly gets worse every settlement cycle.
Gross Sales vs. Net Payout
Your actual gross sales are recorded inside the Settlement Report. What lands in your bank is what remains after Amazon has deducted its charges and withheld any reserves. The gap between gross sales and the net deposit is the entire bookkeeping problem. Ignore it and every financial statement you produce will be inaccurate.
What Gets Bundled Into One Settlement
A single Amazon settlement typically contains all of the following combined into one net number:
- Product sales revenue
- Promotional discounts applied to orders
- Customer refunds and returns
- Referral fees and selling commissions
- FBA fulfillment fees
- Storage fees including monthly and long term charges
- Advertising charges deducted from the account
- Marketplace tax collected by Amazon
- Reimbursements for lost or damaged inventory
- Reserve balances withheld pending review
The Report to Book Workflow
Here is how to move cleanly from Amazon’s data to your ledger every settlement cycle:
- Pull the Settlement Report from Seller Central, or use the Date Range Transaction Report if the settlement crosses a month end
- Break the activity into categories: sales, refunds, each fee type, taxes, reimbursements, and reserve movements
- Post each category to the correct account in your chart of accounts inside QuickBooks, Xero, or whichever system you use
- Match the total posted to the net bank deposit. If they do not tie out, something has been miscategorised or missed
- Review outstanding items: reserves, deferred funds, reimbursements pending, and any payable to Amazon balances
Worked Example: Settlement to Ledger
Here is what a real settlement might look like and where each piece belongs in the books.
Source: Amazon Seller Central Payments Reports documentation and Inventory Ledger documentation
The $2,600.00 bank deposit matches the reconciliation. But the books correctly show $4,200 in gross sales : not $2,600. That distinction is everything.
Which Amazon Seller Fees and Transaction Types Should Be Tracked Separately?
Track fees separately by type. Collapsing everything into one generic Amazon fees line hides margin problems and makes profitability analysis useless. Amazon charges sellers across several distinct categories and each one affects margin differently.
Fee categories sourced from Amazon Seller Central fee documentation: sellercentral.amazon.com/help/hub/reference/G200336920
The Settlement Report and the Fee Preview report inside Seller Central give you the granular breakdown to populate this mapping correctly. The goal is not just accounting tidiness,it is knowing exactly where the money is going at a product level.
How Should Amazon FBA Sellers Track Inventory and COGS?
Inventory is not just an operations issue. It directly affects COGS, gross margin, and whether your books reflect reality. For FBA sellers, the Inventory Ledger is the starting point for getting this right.
What the Inventory Ledger Actually Helps You Track
Amazon’s Inventory Ledger works like a bank statement for stock. It shows daily inventory quantity, location, disposition, and movements across all FBA warehouses. You can see exactly what entered, what sold, what was returned, what was disposed of, and what is still sitting in storage all date stamped. Without reconciling it monthly, you are guessing at your stock position and therefore guessing at your COGS.
Which Costs Belong in COGS
Costs such as product purchase cost, inbound freight, customs duty, packaging, and labeling all feed into the true landed cost of each unit. Include them in your COGS calculations or your gross margin will be overstated.
What to Do With Returns, Removals, and Damaged Stock
Each of these has a different bookkeeping treatment and none of them should be ignored:
- Returned sellable units: reverse the COGS entry for that unit
- Returned unsellable units: expense the cost and reduce inventory
- Amazon reimbursements for lost or damaged stock: post to Other Income: Amazon Reimbursements
- Removal orders: reduce inventory at cost and record any difference as a loss
Why Product Level Profitability Matters
Tracking COGS at the SKU level, not just in aggregate is what gives you real profitability insight. A product appearing to run at 30% gross margin on paper may be running at 8% once storage fees, return rates, and inbound freight are properly allocated. That information only exists if the bookkeeping is structured to capture it.
Should Amazon FBA Sellers Use Cash or Accrual Accounting?
Cash accounting is simpler. Accrual accounting is more accurate for inventory based businesses and the IRS generally requires it for sellers who produce, purchase, or sell merchandise. For most serious FBA sellers, accrual is the right method and it is worth understanding why.
IRS guidance: IRS Publication 538 – Accounting Periods and Methods. CRA guidance: canada.ca – CRA inventory and business income
Why Inventory Changes the Decision
IRS Publication 538 states that businesses producing, purchasing, or selling merchandise are generally required to maintain an inventory and use an accrual method for purchases and sales. The CRA aligns with this for inventory based businesses. The core problem with cash accounting for FBA sellers is timing. Buy 1,000 units in November, sell them through January, and cash accounting records the full purchase cost in November, making November look unprofitable and January look artificially strong. Accrual matches the cost to the period the units actually sold.
When to Review the Accounting Method
It is worth talking to a CPA or bookkeeper about the accounting method if any of the following apply:
- Inventory value is growing significantly year over year
- The business operates across multiple countries or currencies
- A valuation or investor review is coming up
- The current P&L does not match what the business feels like it is actually doing
How Do You Set Up a Workable Amazon FBA Bookkeeping Workflow?
A workable setup needs five things: a dedicated business bank account, a chart of accounts mapped to Amazon’s transaction types, Seller Central report access, a consistent posting workflow, and a monthly reconciliation routine. None of these are optional.
Step 1: Separate the Business Records
Every Amazon business needs a dedicated business bank account. Mixing personal and business transactions is the fastest way to destroy the integrity of the books. Open a separate account and route all Amazon payouts to it.
Step 2: Build a Chart of Accounts for Amazon
A generic small business chart of accounts will not work. At a minimum, the following account lines are needed:
Step 3: Import or Sync Report Data
Download the Settlement Report and transaction reports from Seller Central at each settlement cycle. If using a connector tool like A2X, the data syncs automatically into QuickBooks Online or Xero already broken into mapped categories. Either way, the data has to get into the accounting system accurately.
Step 4: Categorise Transactions Consistently
Every transaction must be posted to the correct account every cycle. Consistency matters more than perfection on day one. If a fee is categorised one way in month one and differently in month three, P&L comparisons become unreliable. Agree on the mapping, document it, and stick to it.
Step 5: Reconcile Payouts to Bank Activity
Once transactions are posted, the total must tie to the actual bank deposit. If there is a discrepancy, something has been miscategorised, a reserve movement was missed, or a reimbursement was not captured. Do not close the period until the reconciliation is clean.
Step 6: The Monthly Close Checklist
Run through these six items every month without exception:
- Pull all reports: Settlement Report, Date Range Transaction Report, Inventory Ledger, Marketplace Tax Collection Report
- Post all entries: Sales, refunds, each fee category, reimbursements, reserve movements
- Tie to bank: Total posted must match the net bank deposit for the period
- Review inventory: Reconcile Inventory Ledger quantities to the accounting system’s stock balance
- Review outstanding balances: Amazon reserves, payable to Amazon items, deferred funds awaiting release
- Review statements and margin: Confirm the P&L, gross margin by product, and cash flow look consistent with what actually happened
Do Amazon Sellers Need QuickBooks, Xero, or an Amazon Connector?
Honestly, you do not need any specific tool. You need an accounting system and a reliable way to get Amazon data into it without breaking reconciliation accuracy. The software supports the bookkeeping logic : it does not replace it. Here is how to think about the choice by stage.
Starting Out: Low Volume
At under 100 orders per month, a spreadsheet combined with manual Seller Central exports can work. The risk is falling behind. Bookkeeping done weekly takes minutes. Bookkeeping left for three months takes days and introduces errors.
Growing Seller: Medium Volume
Between 100 and 500 orders monthly, QuickBooks Online or Xero with manual settlement imports is a reasonable setup. Both platforms handle bank feeds, invoicing, and reporting well.
Active Seller: High Volume
At 500 or more orders monthly, a connector tool like A2X becomes genuinely useful rather than optional. These tools sit between Amazon and the accounting software, pull settlement data, break it into categorised components, and push a reconciliation ready summary into QuickBooks or Xero automatically. The value is consistency and accuracy at volume, not automation for its own sake.
One Thing to Remember
Software that auto categorises transactions still needs human review. The bookkeeping logic must drive the software not the other way around. Automated tools get the mapping wrong sometimes, and a seller who never checks will not notice until the books are badly off.
Do Amazon FBA Sellers Still Need to Think About Taxes If Amazon Collects Marketplace Tax?
Yes : and this is one of the most common misunderstandings among FBA sellers. Amazon collecting marketplace tax does not eliminate your bookkeeping or compliance responsibilities. You still need correct records, correct classifications, and accurate income reporting.
What Amazon May Handle
In many US states and some other jurisdictions, Amazon operates as a marketplace facilitator. Under these rules, Amazon calculates, collects, remits, and, where applicable, refunds supported sales tax on covered transactions. The Marketplace Tax Collection Report in Seller Central confirms what Amazon handled. The tax flows through Amazon, not through the seller’s bank account, and it should not appear as income or expense in the seller’s books.
What the Seller Still Has to Track
Even where Amazon handles marketplace tax, sellers must:
- Keep records of all marketplace facilitated transactions as required by most tax authorities
- Make sure tax amounts are not accidentally double booked as income or expense
- Monitor whether any transactions fall outside marketplace facilitator coverage
- Report income correctly : gross sales before any fee or tax offset is typically the basis for income tax
What Canadian Sellers Should Document
Canadian sellers operating through Amazon are subject to CRA rules on business income and GST/HST. The CRA requires accurate records of all business income including Amazon sales, and sellers need to track whether they are registered for GST/HST and whether their Amazon income crosses registration thresholds. CRA guidance on business income is at: canada.ca/en/revenue-agency/services/tax/businesses/topics/sole-proprietorships-partnerships/report-business-income-expenses.html.
What Not to Assume
Amazon collecting tax is a compliance convenience : not a replacement for accurate records or correct income reporting. Sellers still own their filing obligations, their nexus analysis, and their overall tax position. The bookkeeping needs to reflect that.

What Are the Biggest Amazon FBA Bookkeeping Mistakes to Avoid?
The five mistakes below account for the vast majority of bookkeeping problems among FBA sellers. Most of them come back to the same root cause: treating Amazon’s net payout as the whole story rather than pulling it apart to find the truth.

FAQs About Amazon FBA Bookkeeping
FAQs About Amazon FBA Bookkeeping
How do you do bookkeeping for Amazon FBA sellers?
Pull the Settlement Report from Seller Central, break it into its components, and post each one to the correct account. The core components are gross sales, refunds, referral fees, fulfillment fees, storage fees, taxes, and reimbursements. Then reconcile the total to the bank deposit. Do this every settlement cycle and close the books monthly with the six step checklist above.
What reports do Amazon sellers need for accounting?
The minimum stack is the Payments or Settlement Report, the Payment Date Range Transaction Report, the Inventory Ledger, and the Marketplace Tax Collection Report. The Fee Preview report is useful for spotting upcoming charges. All are available inside Amazon Seller Central.
Is Amazon income taxable in Canada, and are sellers still responsible for sales tax or VAT if Amazon collects it?
Yes to both. Amazon sales income is taxable business income in Canada and must be reported to the CRA. Even where Amazon acts as a marketplace facilitator and handles GST/HST or provincial sales tax, sellers are still responsible for accurate records, correct income reporting, and understanding their own filing obligations.
Which Amazon seller fees and deductible expenses should you track?
Track referral fees, FBA fulfillment fees, monthly and long term storage fees, return related fees, advertising spend, and inbound shipping costs. Fees such as referral fees, fulfillment fees, storage fees, and refund administration fees are deductible business expenses. Inbound freight and shipping may belong inside COGS depending on the accounting method used.
Should Amazon sellers use cash or accrual accounting, and how should inventory and COGS be tracked?
For most FBA sellers with meaningful inventory, accrual is the right method. IRS Publication 538 requires accrual for most merchandise selling businesses. CRA guidance aligns for inventory based businesses. Use the Inventory Ledger to reconcile stock monthly and apply a consistent COGS method : FIFO or weighted average : to match product costs to the correct sales period.
Do Amazon sellers need QuickBooks, and what accounting software integrates best with Amazon?
You need an accounting system : QuickBooks Online and Xero are the most widely used for Amazon sellers : but the platform matters less than the workflow. At volume, pair either with a connector tool such as A2X to automate settlement imports and categorisation. At low volume, manual imports from Seller Central work. The tool serves the bookkeeping logic.
Do Amazon sellers need an accountant, CPA, or bookkeeper?
That depends on volume, complexity, and comfort with the workflow. A bookkeeper handles monthly recording and reconciliation. A CPA handles tax filings, accounting method decisions, and analysis. If inventory is growing, you sell across multiple countries, or the books have not been reconciled in months, professional help is likely the better option. Trying to reconstruct a full year of Amazon records at tax time costs far more than keeping clean books throughout the year.
What are the biggest Amazon FBA bookkeeping mistakes to avoid?
The biggest mistake is booking the net Amazon deposit as revenue. After that: ignoring fee granularity, missing returns and reimbursements, treating inventory as an afterthought, running no monthly close, and letting automation categorise transactions without ever reviewing the mapping. Each of these compounds over time.
Monthly bookkeeping includes recording financial transactions, reconciling bank and credit card accounts, managing accounts receivable and payable, and preparing month-end financial statements. Core deliverables are a reconciled general ledger, Profit and Loss Statement, Balance Sheet, and aging reports for A/R and A/P.
Monthly bookkeeping for Ontario small businesses typically ranges from $350–$1,000+ per month depending on transaction volume, number of accounts, and service scope. We offer fixed-fee packages so you know exactly what you're paying each month—no hourly surprises.
CRA requires businesses to keep all records and supporting documents for generally six years from the end of the last tax year to which they relate. This includes invoices, receipts, bank statements, payroll records, and financial statements. Organized monthly bookkeeping ensures these records exist and are accessible.
Monthly is the standard cadence for active small businesses. Weekly transaction entry with monthly reconciliation and close provides the right balance of timeliness and efficiency. Less frequent bookkeeping leads to catch-up projects and missed errors.
Bookkeeping records and organizes transactions. Accounting interprets them. Bookkeeping produces the general ledger and financial statements. Accounting uses those statements for tax filing, financial analysis, and business decisions. Most businesses need both—bookkeeping for ongoing maintenance, accounting for year-end and strategic work.
If you have regular transactions, CRA filing obligations, or need visibility into cash flow—yes. Monthly bookkeeping prevents the catch-up scramble, ensures GST/HST and payroll compliance, and gives you accurate numbers for decisions. The cost of monthly service is typically less than catch-up work plus penalties for missed deadlines.
We work with QuickBooks Online, Xero, Sage, and Wave. QuickBooks Online is most common for Ontario small businesses due to its Canadian payroll integration and CRA connections. We can work in your existing software or set up new accounts as part of onboarding.
Most clients are onboarded within 5–7 business days. If catch-up bookkeeping is needed, allow 2–6 weeks to bring books current before transitioning to monthly service. Urgent situations can be accommodated—contact us to discuss.
