Never book your Amazon bank deposit as revenue. That figure already has fees, refunds, taxes and reimbursements netted out of it, so recording it as sales will wreck your profit and loss and your VAT return. The fix: break every settlement into its parts, get your VAT treatment right under HMRC’s marketplace rules, file through Making Tax Digital compatible software, and reconcile each settlement to your bank through a clearing account every month.
TL;DR:
- Decomposing settlement reports into specific components ensures accurate recording of revenue, VAT, refunds, and reimbursements, preventing profit distortion.
- UK VAT and MTD rules require digital record-keeping, with sellers responsible for VAT on UK stock regardless of Amazon handling collection.
- Using a dedicated clearing account and automated reconciliation tools like A2X reduces errors and improves audit trail quality.
- Stock in Amazon warehouses, stock in transit, and stock in storage must be tracked separately, with consistent valuation methods like FIFO or weighted average.
- Engaging an ecommerce-focused accountant becomes cost-effective when volume causes manual reconciliation to take too much time or when cross-border VAT complexities grow.

Why Amazon FBA accounting is different from a normal sales ledger
A typical retailer issues an invoice and gets paid the invoice value. Amazon does not work that way. Every fortnight (or thereabouts), Amazon pays out a single lump sum that has already absorbed dozens of separate transaction types, and that number tells you almost nothing on its own.
A single settlement report typically bundles:
- Gross product sales and shipping charged to customers
- Referral fees and FBA fulfilment fees
- Refunds and return-related deductions
- VAT collected and remitted by Amazon under marketplace facilitator rules
- Reimbursements for lost or damaged stock
- Advertising spend on PPC campaigns
Post the net deposit as “sales” and you understate revenue, overstate net margin distortion in the wrong direction, and lose the audit trail HMRC expects to see behind your VAT return. The correct approach, and the one most experienced ecommerce accountants use, is to decompose the settlement line by line and post each component to its own account.
Pro Tip: Open a dedicated clearing account in your ledger and post every settlement into it first. Only once the total matches your actual bank deposit should you clear it out. This one habit catches more misposted VAT and missing reimbursements than anything else in the monthly close.
What are the UK VAT and Making Tax Digital rules for FBA sellers?
Amazon, as the online marketplace, is liable to collect and account for VAT on many sales made to UK customers, but that does not remove your own VAT obligations. HMRC’s guidance on marketplace VAT makes clear that UK-established sellers still account for VAT when required, and overseas sellers can trigger deemed supplies that must be declared correctly.
Three scenarios come up constantly for FBA sellers:
- Consignments valued at £135 or less sold to UK customers via a marketplace are usually treated as a supply by the marketplace itself, not the seller, under the rules set out in HMRC’s guidance on overseas goods sold via online marketplaces.
- Overseas sellers using UK fulfilment centres may create a deemed supply chain that shifts VAT liability between the seller and Amazon depending on stock location and customer location.
- UK-established sellers remain responsible for VAT on goods already in the UK when the sale takes place, even though Amazon handles collection on the marketplace side.
If you are VAT-registered, MTD for VAT requires digital records and functional compatible software, with digital links between any systems you use. Manually retyping figures from a spreadsheet into your VAT return breaks that chain and can trigger penalties under HMRC’s compliance checks guidance. Records must be kept digitally for six years. Your first three moves: confirm your VAT registration status, pick an MTD-compatible workflow, and download and store Amazon’s Marketplace Tax Collection reports from Seller Central as you go, since HMRC can ask for them retrospectively.
How do you turn Amazon reports into clean bookkeeping entries?
Amazon Seller Central holds the source documents your entire ledger should be built from. Pull these every settlement cycle:
- The Settlement report, which lists every transaction type in the payout period.
- The Date Range Transaction report, useful for reconciling gaps between settlement periods.
- The Inventory Ledger, showing stock movements between FBA warehouses.
- The Marketplace Tax Collection report, showing VAT Amazon collected on your behalf.
Amazon’s own settlement report field documentation defines each amount-type and amount-description field, which is what you use to map lines to accounts: gross sales to revenue, refunds to a contra-revenue line, referral and FBA fees to expense or cost-of-goods-sold accounts, and reimbursements to other income.
The reconciliation sequence stays the same however many SKUs you sell: post the full settlement journal into your clearing account, match the total against the actual bank deposit, clear the matched items, then record any post-settlement adjustments Amazon makes after the fact.
Pro Tip: If you are processing more than a couple of settlements a month by hand, it is worth the switch. A connector such as A2X pulls settlement data straight into Xero with the mapping already applied, which cuts posting errors and gives you a cleaner audit trail than manual CSV imports. Manual mapping still works for lower-volume sellers, but it demands discipline, because one mistyped fee code can throw off your VAT return without you noticing for months.
Inventory accounting and COGS: what UK FBA sellers often get wrong
Stock sitting in an Amazon warehouse is not accounted for the same way as stock in transit or stock still on your own shelves, and treating them identically is one of the most common errors sellers make.
Track inventory across four distinct states: goods in transit to Amazon, goods held at FBA warehouses, goods sold or pending sale, and goods still in your own storage. Each state has a different accounting treatment, particularly around when the cost moves from an asset (inventory) to an expense (cost of goods sold).
Your landed cost, the figure you actually capitalise into inventory, should include:
- Unit cost from your supplier
- Freight and import duty to get stock into the UK or into Amazon’s network
- Any inspection or preparation costs before FBA accepts the stock
Most FBA sellers use FIFO or a weighted average method for valuation. Either works, but pick one and apply it consistently, because switching methods mid-year distorts your margin trend and complicates your year-end accounts.
Reimbursements deserve their own quarterly review. Unclaimed reimbursements for lost or damaged stock commonly run to 0.5% to 2% of annual FBA revenue, and Amazon generally allows claims within an 18-month lookback window, so a quarterly audit habit catches money that would otherwise simply disappear from your accounts.
Monthly close checklist for Amazon FBA sellers
Run this sequence every settlement cycle, not just at year end:
- Download the settlement report, transaction report and inventory ledger from Seller Central.
- Post the full settlement journal into your clearing account.
- Match the clearing account total to the actual bank deposit and clear reconciled items.
- Reconcile the Marketplace Tax Collection lines against your VAT accounting, including any reverse-charge or IOSS entries.
- Run an inventory reconciliation and file any outstanding reimbursement claims.
- Compare advertising charges on the settlement against your PPC reports to catch discrepancies early.
Do this consistently and your VAT return practically writes itself by the time the quarter ends.
When does it make sense to hire a specialist Amazon accountant?
Most sellers can manage the basics alone up to a point. That point usually arrives faster than people expect, often around the time monthly settlement volume climbs past a level where manual reconciliation starts eating a full working day, or once a seller is holding stock across several SKUs with genuinely different landed costs.
The clearer signals: rising transaction volume, a growing SKU count that makes manual COGS tracking unreliable, cross-border VAT complications from selling into the EU or holding stock overseas, and repeated reconciliation shortfalls where the clearing account never quite balances.
An ecommerce-specialist accountant brings a chart of accounts already mapped to Amazon’s settlement categories, automated settlement-to-ledger mapping, MTD and VAT handling built around marketplace rules rather than generic retail assumptions, and structured reimbursement audits run on a schedule rather than an afterthought. The value is not doing the bookkeeping you could technically do yourself. It is catching the things a busy founder misses because they are running the business, not auditing it.

How eAccounts supports Amazon FBA sellers
Running your own settlement reconciliation is manageable at low volume. It stops being a good use of your time the moment SKU count, VAT complexity or settlement frequency start eating into hours you should spend sourcing stock or managing ad spend. eAccounts pairs Amazon FBA sellers with a dedicated accountant who builds your chart of accounts around Amazon’s own settlement categories, connects your Seller Central data to Xero, and handles VAT registration, MTD filing and reimbursement audits as part of the ongoing service.
Packages start from £29 per month with an initial consultation to scope your setup, followed by onboarding and a straightforward move onto monthly service, all billed by direct debit with no separate charge for standard VAT filing. If your reconciliations are already falling behind or your VAT position feels uncertain, book a consultation and get a dedicated accountant looking at your settlements before the next filing deadline arrives.

FAQ
Do I need to charge VAT on my own Amazon FBA sales?
It depends on where your stock sits and where the customer is. Amazon often collects and accounts for VAT itself on qualifying marketplace sales under HMRC’s marketplace rules, but UK-established sellers can still be liable depending on stock location.
What counts as functional compatible software for MTD?
It is software that keeps digital records, calculates your VAT return, and links to HMRC’s systems through an API without manual re-entry, as defined in HMRC’s MTD notice. Xero, connected via a settlement import tool, is a common setup among UK FBA sellers.
Should I record the Amazon deposit as my revenue?
No. The deposit is a net figure after fees, refunds, taxes and reimbursements have already been deducted, so recording it as revenue understates your actual sales and distorts your margin. Decompose the settlement report into its component lines before posting anything to your ledger.
How long do I have to claim missing Amazon reimbursements?
Amazon generally allows claims within an 18-month lookback window, and unclaimed reimbursements often amount to 0.5% to 2% of annual FBA revenue. A quarterly reimbursement audit is the practical way to catch these before the window closes.
How much does specialist Amazon FBA accounting cost?
eAccounts packages for ecommerce sellers start from £29 per month, covering dedicated accountant support, VAT filing and Xero-based bookkeeping. Exact pricing depends on transaction volume and is confirmed during the initial consultation.
