Quick answer
For most UK Amazon FBA sellers in 2026, the right setup is Xero (£14–£59/month) + Link My Books (£17–£75/month) + a specialist FBA accountant for VAT and year-end (~£100–£250/month). This stack handles Amazon settlement reconciliation, VAT compliance, multi-currency, and FBA-specific edge cases for under £350/month total. Generic high-street accountants without FBA experience cost less monthly but cause expensive mistakes — typically £5K–£20K of misclassified expenses, missed reimbursements, or VAT errors per year. We use this exact stack inside our 7-figure operation.
Why FBA accounting is different
Standard small-business accounting handles invoices, expenses, payroll, and a quarterly P&L. FBA accounting adds:
- Amazon settlement reports that bundle 30+ transaction types (sales, refunds, FBA fees, ad spend, lost-inventory reimbursements, marketplace tax, etc.) into single fortnightly payouts
- Multi-currency if you sell on amazon.co.uk and amazon.de or pay overseas suppliers
- VAT-aware fee splitting — Amazon's UK fees include VAT that you need to reclaim properly
- FBA inventory valuation at COGS (not retail) for stock at Amazon warehouses
- Marketplace facilitator VAT rules for non-UK-established sellers
- Reimbursement tracking for lost/damaged inventory
A high-street accountant treating Amazon as "one big lump payment" gets all of this wrong. The result: misclassified expenses, missed VAT reclaim, inventory valued incorrectly. Year-end reconciliation becomes a nightmare and HMRC inspections find errors fast.
The three-layer stack we use
Layer 1: Xero (£14–£59/month)
Cloud accounting platform. The base layer. We use Xero specifically because:
- Native Wise + Revolut + Stripe integrations
- Multi-currency support (GBP, USD, EUR)
- HMRC-recognised for Making Tax Digital VAT submission
- Strong integration ecosystem (Link My Books, A2X, Dext, etc.)
- Most UK FBA accountants prefer it
Tier we use: Standard at £45/month. Multi-currency requires this tier or above (Starter at £14 doesn't include it).
Alternatives considered:
- QuickBooks (£14–£90/month): equally capable, slightly weaker FBA-specific integration ecosystem. Fine if you already have it.
- Sage Business Cloud Accounting (£14–£36/month): traditional UK ops, weaker integration ecosystem. Skip for FBA.
- FreeAgent (free with NatWest/Mettle business banking): genuinely free, decent for solo operators below £50K/year. Limited multi-currency support.
For most established FBA sellers, Xero is the default.
Layer 2: Link My Books (£17–£75/month)
The middleware that makes Xero usable for Amazon FBA. Without it, you're manually reconciling every Amazon settlement — a multi-hour weekly job. With it, settlements auto-categorise into clean line items.
What Link My Books does:
- Pulls every Amazon settlement automatically
- Splits each settlement into: net sales (by SKU), Amazon fees (with VAT element separated), refunds, FBA charges, ad spend, lost-inventory reimbursements
- Posts clean journal entries to Xero
- Handles multi-currency cleanly
- Reconciles Amazon's payouts against the GBP that hits your bank
Tier we use: Standard at £29/month (covers up to 2,500 monthly Amazon orders). Pro at £75/month for higher volume + VAT in multiple countries.
Alternative: A2X (£19–£99/month). Same job, slightly different feel. A2X is older, more popular in the US market. Link My Books was built UK-first and we find it cleaner for UK VAT handling.
For most UK FBA sellers, Link My Books is the default.
Layer 3: Specialist FBA accountant (£100–£250/month)
Even with Xero + Link My Books producing clean books, you still need a human for:
- Quarterly VAT return review and submission
- Year-end accounts and corporation tax return
- HMRC correspondence
- Tax planning (dividend vs salary, R&D claims, capital allowances)
- Strategic advice on growth, hiring, exit prep
The right kind: an accountant who has other Amazon FBA UK clients. Generic accountants charge less but don't know how to handle FBA-specific edge cases.
What specialist FBA accountants typically charge:
- £100–£175/month for sub-£500K revenue businesses
- £175–£250/month for £500K–£2M revenue
- £250+/month for £2M+ with complex multi-jurisdiction exposure
Where to find one:
- Amazon FBA UK Facebook groups — recommendations from other sellers
- Link My Books Partner Directory — accountants who already use the same tool stack
- Xero Advisor Directory — filter by "ecommerce" specialism
- Twitter UK FBA community — direct asks usually surface 2–3 names
At Emporify we use Ricky — a specialist who has 20+ Amazon FBA UK clients and built an FBA-specific service. £200/month fixed fee. Worth every penny.
Total monthly cost
| Stack tier | Total | Best for |
|---|---|---|
| Solo operator, sub-£10K/m revenue | £14 (Xero Starter) + £17 (LMB Lite) = £31/m | Pre-VAT, learning the basics |
| Established, VAT-registered | £45 (Xero Standard) + £29 (LMB Standard) + £150 (specialist accountant) = £224/m | Most £20K–£100K/m sellers |
| 7-figure operation | £45 (Xero) + £75 (LMB Pro) + £200 (Ricky) = £320/m | What we run |
Most "generic" UK accountants charge £100–£200/month for a small business. The specialist FBA setup costs slightly more but saves multiples of that in better VAT reclaim, cleaner inventory accounting, and avoided HMRC errors.
What a good FBA accountant should know
Vetting questions when interviewing:
- "How many Amazon FBA UK clients do you have?" — Want at least 5. Below that they're learning on you.
- "Do you use Link My Books or A2X?" — Saying "we use [neither] — I'll just import the CSVs" is a red flag.
- "How do you handle Amazon's marketplace facilitator VAT for cross-border sales?" — Should immediately distinguish UK-established vs non-UK-established seller obligations.
- "What's your fee structure?" — Fixed monthly fee is best. Hourly billing for FBA is a budget trap.
- "Can you give me 2 references from Amazon FBA clients?" — A specialist always can.
If they can't answer 4 of these confidently, keep looking.
Common UK FBA accountant mistakes
These are the ones we see consistently kill sellers:
1. Booking Amazon settlement payouts as a single line
The settlement is a payout, not revenue. Real revenue is the gross sales inside it. Without splitting, your P&L looks like £100K of "income" was £60K — and your VAT return is wrong.
2. Not reclaiming VAT on Amazon UK fees
Amazon's UK referral and FBA fees include VAT. You reclaim it on your VAT return. A surprising number of generic accountants treat Amazon fees as a clean expense — leaving £500–£3,000/year of reclaim on the table.
3. Valuing FBA inventory at retail
Inventory at Amazon warehouses should be valued at cost for tax purposes, not retail. Some accountants miscalculate this, resulting in artificially inflated assets and overstated tax bills.
4. Missing reimbursement income
Lost/damaged FBA inventory reimbursements (whether direct from Amazon or via GETIDA/SellerLocker) are taxable income. Often missed or misclassified.
5. Wrong VAT treatment on supplier returns
Returning unsold stock to a UK wholesaler reverses the original VAT input. Foreign suppliers add complexity. Easy place to miscount.
When to switch from DIY to a specialist
| Stage | DIY workable? | Recommendation |
|---|---|---|
| Pre-VAT (sub-£90K turnover) | Yes | Xero + Link My Books, self-file accounts. Use HMRC online filing. |
| VAT-registered, sub-£200K | Tight | Hire specialist accountant for VAT + year-end at minimum. Continue managing books in Xero yourself. |
| £200K–£1M | No | Full specialist relationship. Xero + LMB feeds them clean data. |
| £1M+ | No | Specialist accountant + tax adviser for planning. Consider FD-level input quarterly. |
Generic high-street accountants are fine until you cross £200K or VAT-register. After that, switch.
Tools for self-management between accountant reviews
If you're managing books between quarterly accountant touches:
- Dext (£14–£36/month) — receipt capture for stock purchases. OCRs invoices, posts to Xero
- Hubdoc (free with Xero) — same job, included
- Xero's bank reconciliation — daily 5-minute review
- Link My Books weekly review — verify auto-categorisation looks right
- Wise + Capital on Tap auto-feeds — direct integration into Xero
15 minutes a week of bank rec + 30 minutes a month of LMB review keeps you in good shape between accountant reviews.
FAQ
Do I need a UK accountant for Amazon FBA?
Below £90,000 turnover (the VAT threshold), you can DIY with Xero + Link My Books and HMRC online filing. Above that — or once VAT-registered — hiring a specialist FBA accountant pays for itself through cleaner VAT reclaim and avoided errors.
What's the best accounting software for Amazon UK sellers?
Xero with Link My Books is the default for most UK FBA sellers in 2026. Xero handles base accounting and VAT submission; Link My Books reconciles Amazon settlements into clean line items. Combined: £45–£74/month.
Is Link My Books or A2X better for UK Amazon sellers?
Both do the same job. Link My Books is UK-first, slightly cleaner UK VAT handling, and our preferred tool. A2X is older with stronger US/Canada market penetration. Either works; pick based on cost match (LMB Standard £29 vs A2X equivalent £49).
How much does an FBA-specialist accountant cost in the UK?
£100–£250/month depending on revenue tier. Sub-£500K: £100–£175/month. £500K–£2M: £175–£250/month. £2M+: £250+/month with strategic advisory.
Can I use FreeAgent for Amazon FBA UK?
Yes for solo sub-£50K operations. FreeAgent's multi-currency is weak for FBA at scale, and there's no native Link My Books integration. Migrate to Xero once you VAT-register.
Do I need to register for VAT just because I sell on Amazon UK?
No. VAT registration is required only when your taxable turnover exceeds £90,000 in any rolling 12-month period. See amazon fba uk vat guide for full details.
What's the cheapest legit accounting setup for UK Amazon FBA?
FreeAgent (free with NatWest/Mettle business banking) + DIY HMRC online VAT filing. Works only sub-£50K, solo, simple operations. Not recommended once you VAT-register.
