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:

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:

Tier we use: Standard at £45/month. Multi-currency requires this tier or above (Starter at £14 doesn't include it).

Alternatives considered:

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:

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:

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:

Where to find one:

  1. Amazon FBA UK Facebook groups — recommendations from other sellers
  2. Link My Books Partner Directory — accountants who already use the same tool stack
  3. Xero Advisor Directory — filter by "ecommerce" specialism
  4. 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.

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:

  1. "How many Amazon FBA UK clients do you have?" — Want at least 5. Below that they're learning on you.
  2. "Do you use Link My Books or A2X?" — Saying "we use [neither] — I'll just import the CSVs" is a red flag.
  3. "How do you handle Amazon's marketplace facilitator VAT for cross-border sales?" — Should immediately distinguish UK-established vs non-UK-established seller obligations.
  4. "What's your fee structure?" — Fixed monthly fee is best. Hourly billing for FBA is a budget trap.
  5. "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

StageDIY workable?Recommendation
Pre-VAT (sub-£90K turnover)YesXero + Link My Books, self-file accounts. Use HMRC online filing.

£200K–£1MNoFull specialist relationship. Xero + LMB feeds them clean data.
£1M+NoSpecialist 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.

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.
