Amazon FBA Accountants

Seller Central reports are the source of truth and the source of most errors. The Date Range Reports, the Settlement Reports, the FBA Fulfillment Reports, and the Pan-EU stock movement reports each tell part of the story. A specialist accountant maps these into a clean monthly P&L showing gross sales by marketplace, FBA fees by category (fulfilment, storage, removal, returns), advertising spend, refunds, and net-deposit reconciliation. Generalist accountants typically import the deposit total and miss the gross-to-net reconciliation entirely — which means the VAT figures and the corporation tax computation are both wrong.

FBA fees come in twelve named categories on Amazon's schedule, and each maps differently for accounting and VAT. Fulfilment fees and storage fees are deductible as cost of sales. Long-Term Storage Fees that hit on the 15th of the relevant months go through accruals. Removal fees and disposal fees are administrative. Aged Inventory Surcharge (the new fee that replaced LTSF in some periods) needs separate tracking. Pan-EU FBA inventory placement fees are charged differently depending on which fulfilment centre your stock lands in. The chart-of-accounts setup needs to anticipate all of these from day one or the year-end reconciliation becomes a forensic exercise.

Pan-European FBA is the single biggest VAT risk for UK Amazon sellers. Once you opt in, your stock is moved between fulfilment centres in Germany, France, Italy, Spain, Poland, and the Czech Republic. Each country has its own VAT registration threshold and obligation — and once stock is held in a country, you have a VAT registration trigger there regardless of sales volume. A UK seller with Pan-EU FBA on can find themselves needing 6+ VAT registrations within months of opting in. Specialist FBA accountants run a pre-opt-in cost-benefit modelling, file the registrations correctly, and handle the periodic returns in each country.

OSS (One Stop Shop) and IOSS (Import One Stop Shop) are the post-Brexit VAT mechanisms that most generalists confuse. UK sellers shipping into the EU under the OSS regime register once (typically in Ireland or another single member state) and report all distance sales across the EU through that single return. IOSS handles the under-€150 imports being shipped into the EU — used heavily for direct-from-warehouse fulfilment. Pan-EU FBA stock movements complicate the picture because stock held in-country falls outside OSS and into local VAT. Getting the OSS-vs-local-VAT split right is the single biggest area where specialist FBA accountants add value.

Inventory valuation under FRS 102 / FRS 105 for FBA sellers requires landed cost — the purchase price, plus inbound shipping, plus customs duties, plus any FBA inbound placement fees that are capitalisable. Generalist accountants frequently expense these on receipt and book stock at purchase price only, which understates inventory and overstates cost of sales for the year. The corporation tax effect is real and recurring; the practice-accounts management view of margin per SKU also breaks under the wrong inventory valuation method.

Repurchase / refurbishment of returned stock is a category most sellers don't track separately. FBA returns sit in your account as either sellable, unsellable, or removed-and-disposed inventory. Sellable returns go back into rotation; unsellable inventory either gets disposed at a fee, removed back to you for repair, or written off at year-end. The accounting treatment differs in each case — disposal is a write-off, removal-and-repair becomes work-in-progress, write-off needs proper documentation for HMRC. A specialist tracks this monthly so the year-end inventory figure is defensible.

Multi-marketplace selling (Amazon UK + Amazon US + Amazon DE + Amazon FR) creates currency reconciliation work that generalist accountants underestimate. Each marketplace settles in its local currency, Amazon Currency Converter takes a margin, and the conversion rate at settlement differs from the rate at sale. Realised FX gain or loss has to be tracked separately from operational margin. For sellers with material non-GBP revenue, the FX line on the P&L can swing the corporation tax computation by tens of thousands.

Amazon Vendor Central (selling TO Amazon as a vendor, rather than ON Amazon as a third-party seller) follows a fundamentally different accounting pattern from FBA. Vendor relationships involve POs, COGM allowances, MDF (Marketing Development Funds), and chargebacks for non-compliant shipments. Sellers running both Vendor and Seller Central need separate chart-of-accounts treatment for the two streams. Specialist accountants handle both; generalists treat them as one.

Amazon UK operates with the Marketplace Facilitator rules — Amazon collects and remits VAT on sales below £135 to UK consumers from non-UK sellers, and on sales to consumers in EU member states under the equivalent EU rules. UK-established sellers handle their own UK VAT but the Marketplace Facilitator collection still touches the books — Amazon's payment to you is net of the MF VAT they remitted, and the VAT-collected portion has to be tracked separately so it doesn't accidentally end up in your taxable revenue.

Amazon Lending and Amazon Capital Services loans are common but accounted for poorly. The repayments are deducted automatically from your settlement disbursements, and the interest portion needs to be split out as a finance cost in the P&L rather than being treated as another operational deduction. Specialist accountants identify and split these correctly; generalists frequently miss them entirely or net them into FBA fees by mistake.
