Selling on Amazon FBA changes how your financials work compared to most businesses. The deposit you receive every two weeks is not your revenue. It is what remains after Amazon subtracts referral fees, FBA fulfillment fees, storage charges, advertising costs, refunds, and other adjustments. Treat that deposit as income and your books hide your true sales and real expenses, which leads to confusion and unnecessary stress at tax time.
Amazon FBA bookkeeping means breaking apart those net payouts and recording every piece of activity in the right place: gross sales, contra-revenue items like refunds and returns, each fee category, inventory costs, and sales tax collected. Do this well and your profit and loss statement shows whether the business is actually making money, your balance sheet reflects the inventory you own, and your tax filings line up with what the IRS sees on your 1099-K.
This guide covers the bookkeeping practices that keep your Amazon seller financials accurate. You will learn how to reconcile settlement reports, track cost of goods sold, handle multi-state sales tax, and choose the right accounting setup. Whether you manage your own books or work with a bookkeeper new to ecommerce, these steps build a reliable system.
If you would rather have clean, tax-ready books without doing any of this yourself, that is our specialty. Our Amazon FBA bookkeeping service unpacks every settlement and keeps your financials accurate month after month.
Why Net Deposits Mislead Your Books
Many sellers record each Amazon payout as revenue, but that deposit is already reduced by fees, refunds, and other line items. To see what your business actually earned and spent, you need to unpack every settlement and post the pieces separately. Gross sales, Amazon fees, refunds, advertising costs, and reimbursements each belong in their own account.
What an Amazon Payout Actually Includes
An Amazon payout is a net number. It starts with your gross sales for the settlement period, then Amazon subtracts referral fees, FBA fulfillment fees, storage fees, return processing fees, and any advertising costs you owe. It also factors in customer refunds, chargebacks, reimbursements for damaged or lost units, reserves Amazon holds back, and sales tax Amazon collected as a marketplace facilitator. The deposit that reaches your bank is what remains after all of that.
For example, if you sold $25,000 in products during a two-week period and Amazon withheld $8,500 in fees, refunds, and ad charges, your bank deposit shows $16,500. Record $16,500 as revenue and you have just hidden $8,500 in sales and expenses.
Gross Sales vs. Amazon Payout
Gross sales are the total customers paid for your products before any deductions. Your Amazon payout is the net cash after all deductions. Your books need both numbers.
Record only the payout and your revenue is understated while your expenses go missing. You cannot calculate your true referral fee percentage, your actual ad spend as a share of sales, or your real fulfillment cost per unit. Your profit and loss statement then shows fewer sales and higher margins than you actually have, which distorts pricing decisions and tax projections. Recording gross sales at the top and listing each fee and deduction below gives you the complete picture, including the real size of your business and every cost that affects your margin.
How Refunds, Returns, and Amazon Fees Get Hidden
When Amazon processes a customer refund, it reduces your next payout, and the same applies to returns, referral fees, FBA fees, storage fees, and selling fees. All of these are netted against your sales within the settlement report, so if you do not break that report apart, those costs stay buried in one lump-sum deposit.
Advertising adds complexity, since Amazon Ads charges may appear in the same settlement or be deducted separately depending on timing. Fail to track ad spend against the correct period and your monthly profit numbers swing for reasons unrelated to actual performance. The fix is to download your settlement reports from Seller Central, separate every line item into its correct category, and post each one individually. Refunds become contra-revenue, referral fees and FBA and storage fees become selling expenses, and ad spend goes to its own marketing line. The result is financials that tell a clear story.
The Core Accounts Every Seller Needs
A clean chart of accounts is the foundation of accurate Amazon seller accounting. Without the right categories, transactions get lumped together and reports become unreliable. You need distinct accounts for revenue, each major fee type, inventory, cost of goods sold, and clearing accounts that bridge Amazon settlements and your bank deposits. Set this up correctly from the start to avoid cleanup later.
Revenue, Contra-Revenue, and Fee Categories
Your chart of accounts should start with a gross sales account that captures total product revenue before deductions. Below that, create contra-revenue accounts for refunds, returns, and promotional discounts, which reduce your top-line sales and keep your net revenue calculation transparent.
Fee categories need their own expense accounts. Set up separate accounts for Amazon referral fees, FBA fulfillment fees, storage fees, return processing fees, and Amazon Ads. Some sellers also break out subscription fees, removal and disposal fees, and inbound placement fees. When each fee type has its own line, you can spot trends and see exactly where margins are shrinking. Accrual accounting, which records revenue when earned rather than when cash arrives, gives a more accurate picture for Amazon sellers, because payout timing rarely matches sales timing.
Inventory, COGS, and Inventory Asset Setup
Inventory accounting for Amazon FBA requires an inventory asset account on your balance sheet. When you purchase products from a supplier, record the cost to that account, where it stays until the units are sold. At the point of sale, the cost moves to your cost of goods sold (COGS) account on the profit and loss statement.
COGS tracking matters because it directly affects your reported profit. Expense all inventory purchases immediately and a large order makes that month look unprofitable even though you still hold unsold units. Properly timed COGS gives you an accurate gross margin for each period. For Amazon sellers, COGS should include the supplier’s product cost, inbound freight, duties, prep and labeling fees, and any other cost required to get the product to a sellable condition. That total is your landed cost per unit, and it is the number that flows into COGS when a unit sells.
Clearing Accounts and Business Bank Account Flow
A clearing account acts as a temporary holding spot in your books. When you record the full detail of an Amazon settlement, the net amount posts to the clearing account. When the actual bank deposit arrives, you match it against that balance, and if the two agree, the clearing account zeros out and everything reconciles. This keeps your revenue and expense accounts accurate regardless of when Amazon sends the money, and a lingering clearing balance tells you something did not match and where to look.
Every Amazon business should use a dedicated business bank account. Mixing personal and business transactions complicates bookkeeping and creates audit risk, so keep Amazon deposits, supplier payments, tax payments, and business expenses in one account, separate from personal finances.
How to Reconcile Settlements Correctly
Settlement reconciliation is where your Amazon bookkeeping comes together. Each settlement report from Seller Central contains many transactions, and your task is to confirm that every dollar in those reports matches what hit your bank account. This process also uncovers missing reimbursements, timing differences, and fee discrepancies.
Which Seller Central Reports Matter Most
Seller Central offers many reports, but a few matter most for bookkeeping. The settlement report is your primary source, breaking each payout into gross sales, refunds, fees, advertising charges, reserves, reimbursements, and the final net deposit, so download the detailed version. Also pull the transaction detail report and the payments report to cross-check order-level data. For inventory, use the FBA inventory reports, including the monthly storage fee report and the inventory adjustments report. For advertising, the Sponsored Products and Sponsored Brands campaign reports show your Amazon Ads spend. The tax document library holds your 1099-K and marketplace tax collection reports, which are critical at year-end when reconciling your reported income with IRS records.
Monthly Settlement Reconciliation Step by Step
Download every settlement report that closed during the month. If a settlement period spans two months, you may need to allocate activity to the correct month for accrual-based books.
Step one: total the gross sales, refunds, fees, ad charges, reimbursements, and reserves from each settlement, and post each category to the correct account in your accounting software.
Step two: calculate the net payout from your settlement detail, which is gross sales minus all deductions, plus any reimbursements or reserve releases.
Step three: compare the calculated net payout to the actual bank deposit. They should match. If they do not, check for split deposits, reserve holds that carried over, or timing differences where a settlement closed but the deposit arrived in a different month.
Step four: zero out the clearing account for each matched settlement. Any remaining balance signals an unresolved difference.
Step five: review the completed entries against your profit and loss statement to confirm that revenue, fees, and refunds look reasonable compared to prior months, and investigate large swings in any category.
Common Gaps: Reimbursements, Damaged Units, and Timing Differences
Amazon may reimburse you for units lost or damaged in fulfillment centers. These reimbursements appear in your settlement report but are easy to overlook, so record them as a separate line item rather than additional sales revenue, keeping your books honest about the true source of funds.
Damaged units create another gap. If Amazon damages your inventory and does not reimburse you automatically, file a claim, track the units involved, and follow up, since unrecovered losses reduce your inventory asset and should eventually be written off as a cost. Timing differences are common too. A settlement may close on the last day of the month but not arrive in your bank until the next. Under accrual accounting, the revenue and fees belong in the month the settlement closed, and a clearing account handles this cleanly. Under cash-basis accounting, be consistent about how you assign deposits to periods, and make sure your accountant understands the lag.
Inventory and COGS Without Guesswork
Accurate inventory and COGS tracking is essential for knowing your true profit. Your inventory is an asset on your balance sheet until a unit sells, and only then does its cost become an expense. Tracking this at the product level gives you the gross margin and product-level profit numbers you need for smart decisions.
From Supplier Invoices To Landed Cost
Every inventory cost calculation starts with your supplier invoices, but the price per unit is only the beginning. To determine your true landed cost, add inbound freight, customs duties, inspection fees, prep and labeling charges, and any other cost needed to get units ready for sale at an Amazon fulfillment center.
For example, if you buy 1,000 units at $5.00 each, pay $800 in ocean freight, $200 in customs duties, and $300 in prep fees, your total landed cost is $6,300, or $6.30 per unit. That $6.30 flows into your inventory asset account and becomes COGS when a unit sells. Keep every supplier invoice, freight bill, and duty receipt organized by purchase order, since these documents support your COGS figures during year-end reviews or audits.
Tracking Units Across Fulfillment Centers
Amazon stores FBA inventory across multiple fulfillment centers, and units move between locations without your involvement. Your inventory reports in Seller Central show where units are, including inbound, available, reserved, unfulfillable, or in-transit quantities. For bookkeeping, the total unit count matters more than specific warehouse locations.
Reconcile your Seller Central inventory reports against your accounting records monthly. The units on your balance sheet should match Amazon’s reported holdings, plus any units in transit from your supplier, minus removals or disposals. If Amazon’s count differs from yours, investigate, because units may be in transit, damaged and marked unfulfillable, or removed without reimbursement, and each of those situations affects your inventory asset and may impact COGS or loss accounts.
When Inventory Becomes Cost Of Goods Sold
Inventory becomes COGS at the point of sale, not at purchase. If you buy $50,000 in inventory but only sell $20,000 worth, your COGS for the month is $20,000, and the remaining $30,000 stays on your balance sheet as inventory. Use a consistent method to determine which units’ costs flow into COGS, whether FIFO, LIFO, or weighted average, matching your tax reporting.
Most Amazon sellers use FIFO or weighted average cost. Choose one, apply it consistently, and document your method. This gives you a clear gross margin, so you can see return on investment by product, spot unprofitable SKUs, and make restocking decisions based on real profitability.
Sales Tax, 1099-K, And Tax-Ready Records
Tax compliance for Amazon sellers involves sales tax collection and remittance as well as income tax reporting. Both require books that separate gross sales from net deposits, track deductible fees, and reconcile to IRS and state records.
Marketplace Facilitator Rules And Sales Tax Nexus
In most US states, Amazon acts as a marketplace facilitator, calculating, collecting, and remitting sales tax on its platform orders. As a seller, you typically do not need to collect sales tax on Amazon orders in those states. Facilitator rules do not eliminate all sales tax obligations, though. If you sell through your own website, at trade shows, or on platforms that do not collect tax for you, you may still owe sales tax in states where you have nexus.
Nexus can be created by inventory stored in a state, employees or contractors in a state, or exceeding economic thresholds. Amazon FBA can create nexus automatically, since Amazon distributes your products across its warehouse network, so you need to know where you have nexus and whether a facilitator is already collecting tax for you. Rules vary by state and can change, so review your obligations periodically, or hand the whole area to our ecommerce sales tax services and stop worrying about it.
Multi-State Sales Tax And Tax Compliance Basics
FBA sellers often have multi-state sales tax obligations because Amazon stores inventory in many states. Even when Amazon collects and remits as a facilitator, some states require you to register, file returns, and maintain records. If you sell on channels outside Amazon, you are responsible for collecting and remitting sales tax in every state where you have nexus, so organize your books by state and channel to file accurately.
Many sellers use sales tax automation software to connect to their sales channels and generate filings. The key steps are the same either way: identify nexus states, register for permits, file on time, and keep records of collections and remittances, because penalties for late or missed filings add up quickly.
How 1099-K Totals Differ From Your Profit And Loss
Amazon issues a 1099-K to sellers who meet the IRS threshold, showing gross payment volume processed through Amazon, including product sales, shipping, gift wrap, and sales tax collected. It does not subtract Amazon fees, refunds, ad costs, or COGS, so the 1099-K total will almost always be higher than your actual revenue and much higher than your profit.
The IRS receives a copy, so your return’s gross number must reconcile with your 1099-K. If your reported income is much lower than the 1099-K and you lack proper documentation for deductions, your audit risk rises. To prepare tax-ready records, start your profit and loss statement with gross sales that match or reconcile to the 1099-K, then show every deduction, including fees, refunds, COGS, advertising, and other expenses, so the math from gross payments to taxable income is clear.
Tools, Reporting, And Month-End Visibility
The right tools and regular monthly reviews turn Amazon data into financial insight you can act on. Your accounting setup must handle settlement-based bookkeeping and report gross sales, separated fees, accurate COGS, and real cash flow.
Choosing Accounting Software For Amazon Sellers
A mainstream cloud accounting ledger forms the backbone of your books, supporting multi-account structures, bank feeds, and customizable charts of accounts. On its own, though, no standard ledger breaks apart Amazon settlements in enough detail for proper bookkeeping. That is where a settlement connector comes in, pulling Amazon settlement data, splitting it into gross sales, fees, refunds, and taxes, and posting summarized journal entries into your ledger, which cuts manual entry and reduces misclassification. For most FBA sellers, a connector is an essential part of the stack.
When choosing your setup, look for a seller-specific chart of accounts, inventory asset tracking, accrual-based reports, and integration with your other channels if you sell on Shopify, WooCommerce, or elsewhere. If evaluating and running all of this is not how you want to spend your time, our specialists select and manage the right stack for you as part of our bookkeeping service.
What To Review In Profit And Loss, Balance Sheet, And Cash Flow
Your profit and loss statement should show gross sales at the top, contra-revenue for refunds and returns, then separate lines for each major fee, COGS, advertising, and operating expenses, with net profit or loss at the bottom. If your P&L lumps everything together, it is not detailed enough to manage the business.
Your balance sheet should reflect your inventory asset, accounts payable, loans, and owner’s equity. If inventory on the balance sheet does not move in proportion to sales, review your COGS calculation. Your cash flow statement shows whether the business generates enough cash to operate, pay suppliers, buy new inventory, and cover taxes. A profitable P&L with negative cash flow often means too much money is tied up in unsold inventory, or growth is outpacing your cash cycle. Review all three monthly, and look for trends rather than month-to-month noise: are fees rising as a percentage of sales, is gross margin shrinking, is cash flow consistently negative despite strong revenue? These patterns guide better decisions, and ecommerce CFO and advisory support can help you read and act on them.
Year-End Cleanup And When To Bring In A Specialist
Most sellers need some year-end cleanup, which means verifying all settlements are accounted for, confirming inventory counts against Seller Central, reconciling the 1099-K to gross sales, reviewing reimbursements, and making sure all bank and credit card accounts are reconciled. If your books have been kept up monthly, cleanup is quick. If settlements are recorded as lump sums, COGS is missing, or sales tax filings are behind, it is more involved.
A specialist who understands Amazon settlements, FBA fees, and ecommerce inventory accounting can resolve the gaps, set up better systems, and prepare accurate, defensible tax filings. If your books need rescuing or you simply want them off your plate for good, book a free consultation with an Amazon bookkeeping specialist and we will get them clean and keep them that way.
Frequently Asked Questions
How do I record Amazon payouts, fees, refunds, and chargebacks accurately?
Download the detailed settlement report from Seller Central for each payout period, then post gross sales, each fee type, refunds, chargebacks, and reimbursements to separate accounts in your accounting software. The net total should match the bank deposit, and a clearing account lets you verify the match.
What is the best way to reconcile bank deposits with Amazon settlement reports?
Total each settlement report’s line items and compare the calculated net payout to the actual deposit in your business bank account, using a clearing account to hold the expected deposit until the cash arrives. If the numbers do not match, check for reserves, split deposits, or settlements that cross month boundaries.
Which accounting setup works best with Amazon sales and marketplace transactions?
A mainstream cloud ledger paired with a settlement connector is the setup most FBA sellers rely on. The connector automatically splits settlement data into the correct revenue, fee, refund, and tax categories, which handles Amazon FBA bookkeeping complexity without manual data entry for every settlement.
How do I handle inventory accounting and cost of goods sold for FBA products?
Record inventory purchases to an inventory asset account on your balance sheet, including all landed costs such as product cost, freight, duties, and prep. Move costs to COGS only when units sell, and reconcile your accounting inventory balance to Amazon’s FBA inventory reports monthly to catch discrepancies from lost or damaged units.
What reports and documents do I need to prepare for sales tax and income tax filing?
For sales tax, keep state-by-state collection records and marketplace facilitator reports from Seller Central. For income tax, gather your 1099-K, a profit and loss statement that starts with gross sales and deducts all fees and COGS, a balance sheet showing inventory, and supporting documents like supplier invoices, settlement reports, and bank statements.
What are the most common bookkeeping mistakes Amazon sellers make, and how can I avoid them?
The most frequent mistake is recording Amazon deposits as revenue instead of separating settlements into gross sales, fees, and refunds. Many sellers also expense inventory purchases immediately rather than tracking inventory as an asset, overlook reimbursements for lost or damaged units, and fail to reconcile the 1099-K to their books before filing. Setting up an accurate chart of accounts and reconciling monthly prevents nearly all of these.
