Let's be honest: the day Amazon becomes a serious part of your revenue is the day your books quietly start lying to you.
You're doing £2m across the business. Amazon is 60% of it. The dashboard says you sold £32,000 yesterday. You open the bank app and the money that lands every two weeks looks nothing like what you sold. The bookkeeper books what hits the bank. The VAT return gets pushed back a week. The panic sets in.
As a specialist social commerce accountant, I spend my days inside Amazon settlement reports. And I can tell you exactly why this happens: Amazon doesn't pay you your sales. It pays you what's left.
Most fast-growing UK brands treat the payout as the truth. It isn't. Here's what actually breaks when Amazon becomes a £1m+ channel, and the system that keeps up with it.
The 14-Day Settlement Machine
Amazon does not pay you per sale, and it does not pay you what you invoiced. Roughly every two weeks it initiates a disbursement: the released transactions across the whole account, netted down into one transfer. The money can then take up to five business days to reach your bank. Deferred sales and reserves stay in Amazon until they're released. One number, and not everything is in it.
Look inside that number and you'll find the full fee stack. Referral fees run 8% to 15% in most categories on Amazon's own UK rate card, updated again this year. On top of that: FBA fulfilment fees per unit based on product, dimensions and shipping weight, monthly storage, aged-stock surcharges, refund administration fees, and a 1.5% fuel and logistics surcharge on UK fulfilment fees since April 2026. Advertising only comes out of the settlement when it's billed to your seller account. All of it comes out before you see a penny.
Now do the maths on your own business. A £400,000-a-month channel at a 15% referral fee gives Amazon £60,000 before fulfilment, storage or a single refund. A 14-day disbursement cycle doesn't mean half a month of sales is always held: with steady £400,000 monthly sales, the average accrual is about seven days, £93,000 gross or £79,000 after a 15% referral fee. Delivery-date reserves and deferred transactions can push the real balance higher, so read your actual number from the Payments dashboard. Either way, it's your cash parked with Amazon. Not profit.
And it gets worse if your numbers wobble. Refund rates climb and Amazon can hold a reserve against your balance. Fees exceed your sales and the account runs negative, which is exactly as scary as it sounds.
The Net Payout Trap
Here's the mistake I see in almost every Amazon bookkeeping file we inherit: the payout is booked as sales. Amazon pays you net. If your accounts record that net number as your revenue, two things happen, and both of them are expensive.
First, you under-report turnover. The £170,000 of fees and ads Amazon took out of your year never appear anywhere. You are reporting the net. UK accounting standards for a principal seller record customer consideration gross of Amazon's charges, with VAT excluded from revenue and the charges as expenses. Reporting the net understates turnover and hides the margin structure. It's also a margin blindfold: you can't see whether referral fees, fulfilment or advertising is eating the business, because they're all hidden inside one bank line.
Second, you miss the VAT. Amazon charges 20% VAT on most of its UK fees, including advertising. If the fee never appears in your books as a gross expense, you never reclaim that input tax. You're leaving recoverable input VAT inside your cost base.
We recently took on a UK Amazon private label seller in health and wellness, seven-figure turnover. Their books showed £580,000 of gross sales, taken straight from the net payouts. The settlements actually showed £750,000. Amazon fees and ads of £170,000 were completely hidden. Of that total, £87,000 was supported by standard-rated VAT invoices, which included £14,500 of recoverable input VAT, recovered as a credit through HMRC's formal error correction process. The full detail is in the case study, and it's a pattern that shows up in about 90% of the high-volume FBA files we inherit.
VAT at Scale: The Bits That Cost Real Money
At £1m+ you're long past the £90,000 registration threshold, and you've been filing digitally under Making Tax Digital for years. The problems at your level aren't registration. They're the three leaks.
The first leak is the VAT inside Amazon's fees. Amazon issues VAT invoices for seller fees every month. Seller fee and FBA invoices live in Seller Central under Reports, in the Tax Document Library; advertising invoices are in the Amazon Ads console under Administration, Billing and Payment, Billing, then Documents. Most sellers never open either. On £50,000 of VAT-inclusive fees a month, the 20% VAT inside them is £8,333 of reclaimable input tax (if the £50,000 is quoted before VAT, it's £10,000). The automation tools, Link My Books and A2X, are the industry standard, but only as good as their tax-code mapping. We regularly see "Amazon Advertising" mapped to a no-VAT code instead of 20% on expenses, and that single error bleeds cash silently for years.
The second leak is import VAT. Your FBA stock arrives in the UK and import VAT is charged at the border. If you're not using postponed VAT accounting, you're paying it upfront and reclaiming it later, cash out of the business for weeks. With PVA you declare and recover the import VAT on the same VAT return. For a fully taxable business on standard accounting that's cash-neutral; Flat Rate Scheme and partially exempt businesses can still carry a net cost. PVA imports use the monthly postponed import VAT statement; paid import VAT is proved by the C79 certificate in the CDS dashboard. Download and keep both, because online statements move to the archive after six months.
The third leak is the Flat Rate Scheme. £150,000 is the joining test, based on expected taxable turnover excluding VAT; the normal compulsory exit test is more than £230,000 of VAT-inclusive total income. FRS users generally can't reclaim VAT on Amazon service fees, but whether voluntary exit saves you money depends on the numbers. Standard accounting unlocks the reclaims when the sums say so.

HMRC Is Reading Your Settlements
Here's what most sellers don't realise until the letter arrives: Amazon reports you to HMRC. Under digital platform reporting, it hands over your identity, what you were paid each quarter after deductions, the fees and taxes withheld, and your transaction counts.
It's not item-level. Amazon doesn't report what you sell. The report contains quarterly amounts after platform deductions, so HMRC can use it for compliance checks, and those totals should reconcile to your declared numbers through a documented bridge. If your filed VAT and corporation tax look nothing like your Amazon data, the enquiry letter is never fun.
This is why "the books are close enough" stops being acceptable once Amazon is a real revenue line. Close enough is exactly what an enquiry is built on. I wrote the full breakdown of what HMRC's platform reporting means for online sellers if you want the detail.
The System That Keeps Up
You don't need a bigger finance team. You need a system that treats Amazon as what it is: a settlement machine, not a bank.
The brands that scale past £1m of Amazon revenue without the wheels coming off all do the same five things:
- Reconcile the settlement report to the bank every two weeks, line by line. A quarter of unreconciled Amazon is a quarter of blind decisions
- Record revenue gross when control of the goods passes, VAT excluded, and each Amazon fee in the period the service is received, accruing material uninvoiced charges at month end. The payout becomes a cash movement between balance sheet lines
- Map the fee anatomy: referral, fulfilment, storage, advertising, refunds and reimbursements each get their own ledger line, so you can see which one eats your margin
- Automate the pull with A2X or Link My Books into Xero or QuickBooks, then check the tax codes. The automation is only as good as the mapping
- Close the month in the first week, with the settlement tied out to the penny and VAT set aside as you sell
One more line for the multi-marketplace crowd: sell into the EU or the US and your proceeds may originate in euros and dollars. If Amazon or your bank converts them, record the conversion charge and any exchange gain or loss separately, or they vanish into the FX spread. The same discipline applies across TikTok, Amazon and Shopify together.
When Amazon reimburses you for lost or damaged stock, the credits land in the settlements as adjustment lines. Reconcile them when they arrive and map them to their own account, or they'll sit wherever the mapping drops them. Our reimbursements guide covers the claims side.
We work with Amazon sellers from £1m to £15m+, and we've seen both sides of this. A celebrity-backed consumer brand north of £10m in revenue had financials so unreliable that an investment round was delayed while we rebuilt them. A pioneer brand sold for roughly twice what the founder expected once the accounts were clean. The counting is the difference between a raise that happens and a raise that stalls.
Frequently Asked Questions
Why doesn't my Amazon payout match my sales?
Because you're paid a net disbursement roughly every two weeks, not per sale. Referral fees, fulfilment, storage, refunds and adjustments all come out first, and advertising too when it's billed to the seller account. The settlement report explains the disbursement, but it excludes deferred transactions and reserves, so read it alongside the order and transaction reports.
Should I record the payout or the sale as revenue?
The sale, gross, when control of the goods passes. Fees are expenses in the period the service is received. Booking the net payout as sales under-reports turnover, hides the fee stack that decides whether you're profitable, and leaves recoverable VAT inside your costs.
Can I reclaim VAT on Amazon's fees?
Yes. Amazon charges 20% VAT on most of its UK fees, including advertising. Seller fee and FBA invoices are in Seller Central under Reports, Tax Document Library; advertising invoices are in the Amazon Ads console. On £50,000 of VAT-inclusive fees a month that's £8,333 of reclaimable input tax.
What is postponed VAT accounting and do I need it?
It lets you declare and recover import VAT on the same VAT return instead of paying it upfront at the border. For a fully taxable business on standard accounting, that's cash-neutral; Flat Rate Scheme and partially exempt businesses can still carry a net cost. For FBA importers it's free cash flow you're handing to HMRC for weeks at a time.
Does Amazon tell HMRC what I earn?
Yes. Under digital platform reporting, Amazon reports your identity, quarterly consideration after deductions, fees withheld and transaction counts. The totals, reported after deductions, are available to HMRC for compliance checks, so keep a documented reconciliation from them to what you file.
Do I need A2X or Link My Books?
At £1m+ of Amazon revenue, yes. But they're only as good as their configuration. A tool with "Amazon Advertising" mapped to a no-VAT code can cost you five figures a year on a big ad spend. The tool pulls the data; a human who reads settlements makes it right.
Summary: Get the Net Payout Out of Your Head
Amazon pays you what's left, not what you earned. Book the payouts as sales and you under-report turnover, hide the fees, miss the VAT, and discover the truth at the worst possible moment: an enquiry, a raise, or a sale.
The brands that win treat the settlements as the starting point, not the whole story. They reconcile every two weeks, reclaim the VAT in the fees and imports, and know their margin to the line item.
Your Amazon business is not what your books say and not what the dashboard says. The truth is in the settlements. Go read them.
