You made 400 sales last month. Amazon deposited USD 27,230. If your books record that deposit as revenue, every number below it is already wrong.
Amazon does not pay you your sales. It pays what is left after referral fees, fulfillment fees, storage, refunds and advertising come out, then reports the gross figure to the Internal Revenue Service anyway. Amazon seller accounting is the work of pulling that one payout apart until the deposit, the profit and loss statement and the tax return finally agree.
It is the hardest form of ecommerce bookkeeping because one settlement carries six kinds of transaction.
Why Amazon Seller Accounting Starts Inside the Amazon Settlement Report
The Amazon settlement report is the source document for accounting for Amazon sellers. The bank statement is not. Amazon closes a settlement period every 14 days and nets 6 transaction types into one disbursement.
Your bank sees one line. Your books need all six, because two are not expenses at all.
| Settlement line | What it is | Where it posts |
|---|---|---|
| Product sales | Gross order value | Revenue |
| Refunds | Money returned to buyers | Contra revenue, never an expense |
| Referral and FBA fees | What Amazon charges to sell and ship | Operating expense |
| Advertising | Sponsored Products spend | Marketing expense |
| Marketplace facilitator tax | Sales tax Amazon collected and remitted | Neither revenue nor expense |
| Reserved balance | Earned money Amazon still holds | Receivable, not deferred income |
The reserved balance is the line sellers never post. It is money you have earned and cannot spend, so a reserve of USD 2,100 left off the books understates your assets and your sales in the same month.
One Amazon Settlement of USD 48,000 Becomes a USD 27,230 Deposit
Take one 14 day settlement period carrying USD 48,000 of gross product sales.
| Line | Amount |
|---|---|
| Gross product sales | USD 48,000 |
| Less refunds to buyers | USD 2,400 |
| Less referral fees at 15 percent | USD 7,200 |
| Less FBA fulfillment fees | USD 4,560 |
| Less monthly storage fees | USD 610 |
| Less Sponsored Products advertising | USD 3,900 |
| Less reserve not yet released | USD 2,100 |
| Bank deposit | USD 27,230 |
Net sales after refunds are USD 45,600. Amazon fees total USD 16,270, which is 33.9 percent of gross sales. The deposit lands USD 20,770 below the gross figure.
That gap produces the two Amazon FBA seller mistakes that cost the most, and they run in opposite directions.
- Post the USD 27,230 deposit as revenue and you understate gross receipts by USD 20,770, while USD 16,270 of real deductions never reach the return.
- Post the USD 48,000 as revenue and never record the fees, and you overstate gross profit by USD 16,270.
Accounting for Amazon Fees: Which Ones Are Expenses and Which Reduce Sales?
Accounting for Amazon fees goes wrong because sellers treat every settlement deduction as one expense bucket. Two of them are not expenses. Refunds reduce revenue, and facilitator tax never reaches the profit and loss statement.
The rest are genuine operating costs.
- Referral fees, a percentage that varies by product category, sit in cost of sales.
- FBA fulfillment fees, priced by unit size and weight, also belong in cost of sales.
- Monthly storage fees are a holding cost and belong with warehousing rather than fulfillment.
- Aged inventory surcharges escalate in day based tiers and bill monthly, so read the tier off your own surcharge report rather than assuming a 12 month grace.
- The USD 39.99 Professional selling plan fee is fixed overhead and does not move with sales.
Fulfillment method decides which of these you carry, which is why Amazon FBA versus FBM changes the expense side as much as the compliance side.
Why Your Form 1099-K Will Never Match Your Amazon Bank Deposits
Amazon files a Form 1099-K when payments for goods or services exceed USD 20,000 in more than 200 transactions. The figure on that form is the gross amount, and gross means something very specific.
The Internal Revenue Service defines the gross amount as the total of reportable payment transactions “without regard to any adjustments for credits, cash equivalents, discount amounts, fees, refunded amounts, shipping amounts, or any other amounts.”
Read that against the worked example above.
- Amazon reports USD 48,000 for that settlement period. Your bank received USD 27,230.
- The USD 20,770 difference is not missing income. It is fees, refunds and a reserve.
- Revenue on the return has to start at the gross figure, with every deduction claimed separately underneath it.
A seller posting deposits as revenue files a return whose top line is USD 20,770 short of the form the Internal Revenue Service already holds. The notice arrives long after the year has closed.
Cash Basis or Accrual: How Should FBA Inventory Be Recorded Under Section 471(c)?
One threshold answers both questions, and most Amazon sellers sit well below it. Accounting for Amazon FBA turns on the gross receipts test, because that test controls the method and the inventory treatment together.
For tax years beginning in 2026, Revenue Procedure 2025-32 sets that threshold at average annual gross receipts of USD 32,000,000 or less across the 3 prior years.
- Publication 538 lets a qualifying small business taxpayer treat inventory as non incidental materials and supplies, or conform inventory to the method used in its own books and records.
- Cash basis reporting becomes available even though you hold physical stock, which most sellers assume is closed to them.
- Inventory still cannot be expensed the day the purchase order is paid. Under either route the cost lands when the unit sells.
Expensing a USD 60,000 inventory purchase in the month it is paid moves that money into the wrong period twice.
What Do Marketplace Facilitator Laws Leave an Amazon Seller Responsible For?
Marketplace facilitator laws changed this obligation completely. The old warning about owing tax wherever your inventory sits is now wrong, because Amazon collects and remits that tax itself. What survives is a filing duty.
- New York relieves a marketplace seller of collecting sales tax on facilitated sales once it holds a Certificate of Collection, and still requires those sales reported on its own periodic returns as nontaxable sales.
- Washington asks the seller to enter marketplace sales in the deduction field named Gross Sales Collected by Facilitator, and to keep filing business and occupation tax.
- Sales made away from Amazon, on your own store or by wholesale, stay entirely yours to collect and remit.
On the USD 48,000 settlement above, the facilitator tax Amazon collected is not revenue at all. The real exposure is a deduction only return nobody filed, which is a penalty over paperwork, not an audit over unpaid tax.
What Changed for Amazon Seller Accounting in 2026?
Two changes landed in the same month and both hit the books rather than the storefront. Anyone reconciling 2026 against a 2025 template is out on both.
- Amazon confirmed in its 2026 update to United States referral and Fulfillment by Amazon fees that changes take effect on 15 January 2026, that FBA fees rise by an average of USD 0.08 per unit sold, or less than 0.5 percent of an average item’s selling price, and that there are no new FBA fee types in 2026.
- The Form 1099-K threshold reverted to USD 20,000 and more than 200 transactions under the One, Big, Beautiful Bill, well above the figures several platform help pages still displayed through 2025.
On 30,000 units a year, an average USD 0.08 increase is USD 2,400 of margin that no price change funded. Where a platform help page and a revenue authority disagree, the authority wins.
Amazon Seller Bookkeeping by Business Type
Private Label Sellers Holding FBA Inventory Across Fulfillment Centers
Amazon seller bookkeeping is not one process, and 3 seller shapes break in three different places. Private label sellers carry the largest inventory balance and the largest storage exposure, so Amazon FBA accounting for this group lives or dies on the inventory account.
Units sit across multiple fulfillment centers under one seller identifier, so quantity on hand is an Amazon number, not a warehouse number you can count yourself.
- Reconcile the inventory ledger to Amazon’s inventory report every month, not at year end.
- Post landed cost, including inbound freight and duty, into inventory instead of into cost of sales on arrival.
- Treat inventory Amazon lost or damaged as a receivable until the reimbursement clears, then match it against unit cost.
A 2 percent unreconciled variance on a USD 400,000 inventory balance is USD 8,000 of profit sitting in the wrong year. It then compounds, because next year opens on the same wrong balance.
Sellers Running Amazon and Shopify on One Set of Books
Two channels paying on two rhythms is where the Amazon Shopify payouts mismatch starts. Shopify settles through a payment processor within days. Amazon settles on a 14 day cycle and holds a reserve, so the two never line up inside the same period.
Merging both into one revenue account destroys channel margin permanently, because once the fees are pooled there is no way to split them back out by channel.
- Give each channel its own clearing account so deposits reconcile against that channel’s own settlement, and so a delayed payout shows as a balance rather than a gap.
- Keep one inventory account, because the same units sell through both, and split only the fees.
- Report contribution margin per channel, since referral fees make Amazon structurally less profitable per unit sold.
Getting this right is the whole discipline of multi-channel ecommerce accounting, and it starts at the clearing accounts rather than at the reporting layer.
Resellers and Wholesalers Running High Transaction Counts
Resellers move thin margins across thousands of low value orders, so a 1 percent posting error does proportionally far more damage here than it does to a private label brand.
Line by line reconciliation stops being possible somewhere past a few thousand orders a month, so the method itself has to change.
- Reconcile at settlement summary level and test a sample of order lines, rather than attempting every transaction.
- Watch the referral fee percentage by category, because a category mix shift silently changes blended margin.
- Track returns as a rate rather than a total, so a rising rate is visible before it reaches the profit and loss statement.
At a 3 percent net margin, USD 1,000,000 of sales leaves USD 30,000 of profit. One misposted fee category can consume a third of that in a single quarter, and only a sampled reconciliation run every settlement period catches it early enough to matter.
The Monthly Amazon Seller Accounting Checklist
Bookkeeping for Amazon sellers works when it is a fixed monthly sequence rather than a year end reconstruction. Six steps close a month properly.
- Break every settlement into its 6 transaction types and post each to its own account.
- Record refunds as contra revenue and facilitator tax as neither revenue nor expense.
- Carry the reserved balance as a receivable so earned sales are not missing from the period.
- Move inventory cost into cost of sales as units sell, never at purchase.
- File every state return you are registered in, including deduction only returns.
- Produce the profit and loss statement before the 10th of the following month.
Skip step one and every later step inherits the error. Skip step five and the penalty arrives even though Amazon already paid the tax on your behalf.

What a Multi-Platform Revenue Reconciliation Rebuild Actually Involves
A tour operator selling across 8 booking platforms arrived with nearly a year of unposted bank transactions and a USD 146,000 negative balance in advertising caused purely by posting errors. The platforms included Xola, GetYourGuide, Viator and Booking.com.
The mechanism is identical to Amazon. Gross platform value was matched against net deposits, and commission fees moved between periods, so nothing ever tied.
- Gross platform value was recorded as unearned revenue, then released as delivered.
- Platform receipts were matched to bank deposits monthly, which is the only way commission variation reconciles.
- Eight bank accounts and 2 credit cards were reconciled for the full fiscal year, and 16 accounting issues were resolved inside 90 days.
The lesson that transfers to Amazon is the matching period. Chasing a per order match against a netted payout never closes, because the fee that broke it was charged in a different period. That multi-platform revenue reconciliation took 90 days.
Our Compliance and On Time Delivery Guarantees
Amazon accounting errors compound quietly, so we carry the cost of ours. Both guarantees below apply to every Amazon seller we serve, and they sit behind our retail and ecommerce accounting services.
Regulatory Compliance Assurance. We ensure all tax filings, payroll, and financial reports meet compliance standards. If an error on our part results in a financial penalty, we will cover the cost.
On Time Delivery Guarantee. Monthly, quarterly, and annual reports are delivered without delays. If we miss a compliance deadline due to our fault, we refund 50 percent of your service fee for that period.
What Correct Amazon Seller Accounting Produces Every Month
Correct Amazon seller accounting produces three numbers that agree, and that is the whole test. Treat it as an operating standard rather than an Amazon accounting guide you read once.
- Gross revenue in your books matches the gross figure Amazon reports on Form 1099-K.
- Every deduction between that figure and the USD 27,230 deposit is claimed as its own expense line.
- Inventory sits on the balance sheet until the unit sells, and the reserve beside it as a receivable.
Get the first one wrong and nothing below it can be trusted.
Find out what your last twelve settlements actually say.
We reconcile your recent settlements, map every fee category to the right account, and compare recorded revenue against the gross figure on your Form 1099-K. You get back the size of the gap, which state registrations need deduction only returns, and whether the Section 471(c) route is open. Thirty minutes, one clear answer.

Frequently Asked Questions About Amazon Seller Accounting
Do I Need an Amazon Seller Accountant, or Will a General Bookkeeper Do?
You need an Amazon seller accountant once you hold FBA inventory or sell into more than one state, because both create work a general bookkeeper is unlikely to have seen before.
The settlement report is the reason. A general bookkeeper reconciles a bank deposit and stops there, which posts a net figure as revenue and hides every fee inside it. An Amazon FBA tax accountant works the other direction, starting from the settlement and proving the deposit out of it.
- Splitting 6 transaction types out of one disbursement, including the reserve nobody posts.
- Reconciling inventory to Amazon’s own report rather than to a physical count.
- Filing deduction only state returns where Amazon has already remitted the tax.
Below roughly USD 250,000 of annual sales, a trained bookkeeper running the right settlement process is usually enough on its own. Above it, the multi state filing work is what tips the decision.
How Do I Handle Refunds and Chargebacks in Amazon Accounting?
Record every refund as contra revenue against sales, never as an expense and never netted into the sales figure itself. Netting is what makes a refund invisible, and an invisible refund makes your return rate impossible to read.
A refund also has three moving parts rather than one, and each of them lands in a different place in your books.
- The original sale stays in revenue for the period it actually happened in.
- The refund reduces revenue in the period Amazon debited your account.
- The referral fee credit Amazon returns reduces your fee expense, while the fulfillment fee usually does not come back at all.
Chargebacks follow the same treatment with one difference. They carry their own dispute fee, which is an expense in its own right and should never be buried inside a refund total. Tracking the two separately shows whether a rising rate is a product or a fraud problem.
What Is the Best Amazon Seller Accounting Software to Use?
The right Amazon seller accounting software depends on order volume and how many channels you sell on, not on a ranking. What matters is whether the tool splits the settlement before it reaches your ledger.
Tools such as A2X, Xero and QuickBooks with an Amazon connection are commonly used for exactly that job, and the choice follows your volume.
- Under a few hundred orders a month, a general ledger plus a monthly settlement journal is enough.
- Past that, a settlement splitter earns its cost immediately, because manual splitting stops being reliable.
- At 2 or more channels, per channel clearing accounts matter more than the software brand does.
Software alone changes nothing. A connector configured to post the net deposit as revenue reproduces the USD 20,770 error automatically, every 14 days, faster than any human could. Check the mapping the day it is installed, then again after the first full month.
How Often Should an Amazon Seller Reconcile Settlement Reports?
Reconcile every settlement period, which means roughly twice a month, then close the month formally by the 10th. Reconciling quarterly sounds efficient and is not, because a fee mapping error found in April has already been repeated 6 times.
The cadence matters more than the effort here, for three separate reasons.
- Reimbursement claims for lost or damaged inventory carry filing windows, so a claim you find late may be a claim you can no longer make.
- Reserve balances move between periods, and a stale reconciliation misstates both assets and sales.
- Category fee changes show up as margin drift, which is only visible against a recent baseline.
Two hours per settlement is a realistic budget once the account structure is right, and considerably less once the split itself is automated. The first two months are the slow ones.
Which Amazon Expenses Can a Seller Actually Deduct?
Every genuine cost of running the business is deductible, and the reason sellers miss deductions is that Amazon already took the money before the deposit landed. That makes managing deductions Amazon sellers already paid a bookkeeping job rather than a tax planning one.
If the fee never entered your ledger, no return can claim it.
- Referral, fulfillment, storage and aged inventory charges, all deducted inside the settlement.
- Sponsored Products advertising, the USD 39.99 monthly selling plan fee, and software subscriptions.
- Inbound freight and duty, which belong in inventory cost and reach the return through cost of goods sold.
- Removal, disposal and return processing charges.
On the worked example above, USD 16,270 of a single settlement period was deductible cost. Post the deposit as revenue and none of it is claimable.
What Does an Amazon Bookkeeper Do That a General Bookkeeper Does Not?
An Amazon bookkeeper starts from the settlement report and works forward to the bank, while a general bookkeeper starts from the bank and works backward. That single difference decides whether your revenue figure is gross or net.
Three tasks sit entirely outside standard bookkeeping practice, and all three are routine for an Amazon seller.
- Splitting a netted disbursement into revenue, contra revenue, expenses, facilitator tax and a receivable.
- Carrying inventory across fulfillment centers you cannot physically count, reconciled to Amazon’s own report.
- Filing state returns that report marketplace sales as nontaxable because Amazon already remitted the tax.
None of that appears in general bookkeeping training. That is how an experienced bookkeeper produces clean looking books whose top line is 43 percent short of the figure the Internal Revenue Service holds. The books balance perfectly. They are simply measuring the wrong number, and no amount of tidiness will surface the gap on its own.
How Does Amazon FBA Bookkeeping Differ From FBM Bookkeeping?
Amazon FBA bookkeeping carries an inventory asset inside Amazon’s warehouses and a stack of fulfillment charges, while FBM keeps stock and shipping costs under your own control. Bookkeeping for Amazon FBA sellers therefore needs 2 accounts that FBM does not.
The differences change which accounts you open, not only the amounts posted to them.
- FBA inventory sits at third party locations, so quantity on hand comes from Amazon’s report rather than a count you control.
- FBA adds fulfillment, storage, aged inventory and removal charges, all deducted at settlement before you see the money.
- FBM shipping is paid by you directly, so it arrives as a normal supplier invoice and never touches the settlement.
Sellers running both methods need fulfillment tagged at order level, or blended margin hides which of the two is actually profitable. That tag is also what lets you price the same unit differently by method, and drop the method that loses money on it.
