Marketplace seller software for VAT-registered UK sellers, checked against HMRC records

What to take away

HMRC's Making Tax Digital rules require VAT-registered sellers to keep digital records and file through compatible software.
A marketplace VAT report is source data, not a complete VAT record.
Claims about automatic VAT treatment should be tested against digital links, VAT codes and audit trails.
Product research tools do not replace accounting or VAT record keeping.
Software due diligence should ask for evidence that matches your Amazon, eBay or Etsy records.

VAT duties that shape software choice

A UK business must register for VAT once taxable turnover passes £90,000, as set out in VAT registration. After registration, the seller owes VAT returns, digital records and evidence for input and output tax.

Making Tax Digital for VAT obliges VAT-registered businesses to keep digital records and use compatible software to file, as explained in Making Tax Digital for VAT. The rules cover sales, refunds, fees and marketplace deductions.

Software marketing often starts with features. The safer test starts with duties. Does the tool store VAT rates, link transactions digitally and produce an audit trail? Does it keep source reports from Amazon or eBay?

HMRC publishes a list of MTD compatible software. That list helps separate accounting platforms from repricing, listing or research tools.

On the HMRC list, Xero, QuickBooks, Sage Business Cloud, FreeAgent and KashFlow are compatible for MTD VAT filing. A2X and Link My Books are marketplace seller tools; check whether the specific product is on the HMRC list for MTD VAT filing, or whether it passes data to a listed platform.

No software can remove the need to check marketplace VAT reports. The seller remains accountable for the figures filed.

Example: checking an Amazon VAT report claim

A seller sees a tool advert that says it handles Amazon VAT automatically. The VAT report may show gross sales, fees and refunds, but it may not split VAT rates by product type.

Ask for one month of data. Compare the tool's output with the Amazon VAT Transaction Report and the VAT return. Check refunds, postage, vouchers and marketplace fees.

If the tool cannot show a digital link from the report to the return, the claim is incomplete for MTD purposes. The seller still needs a record of adjustments.

Records that Amazon and eBay sellers already hold

Amazon and eBay sellers hold settlement reports, transaction reports, invoices, credit notes and fee statements. These are VAT records when they affect taxable supplies.

The reports often use marketplace language, not HMRC boxes. A software tool should map each line to output tax, input tax or a non-VAT movement.

Choosing product research tools is a separate exercise. The practical guide to marketplace product research tools UK explains how to compare Jungle Scout, Helium 10, Keepa, Terapeak, ZIK Analytics and EverBee costs without treating feature lists as tax evidence.

That guide helps with demand and margin. It does not prove that a VAT calculation is correct.

Signs that software spend is justified by records

Record problems show up before a purchase. The article on six signs a seller needs marketplace software reads those signs from late VAT returns, unreconciled fees, manual spreadsheets and channel growth.

Use the signs to decide whether a tool solves a record duty or only adds another dashboard. A repricing tool can change prices, but it may not fix VAT codes.

Inventory management software may track stock. It may not produce an MTD-compatible VAT return. The distinction matters for a VAT-registered seller.

Due diligence steps for marketplace seller software

Export one full VAT period from every marketplace you use.
List every tax linesales, refunds, fees, postage, advertising and storage.
Ask the provider to map each line to your VAT return boxes.
Test the digital link from source report to filed return.
Record the result, including any manual journals.

Advertising claims and correction

Software adverts can promise time savings and automatic compliance. Those claims need substantiation, and the page on advertising checks for marketplace software offers explains how to review prices, endorsements and correction routes.

A VAT-registered seller should treat a compliance claim like an accounting claim. Ask which HMRC record duty the feature supports.

If the advert cannot name the duty, the claim is marketing copy. Do not let it replace your own VAT records.

Common questions

Does MTD for VAT apply to every marketplace seller?

No. It applies to VAT-registered businesses. A seller below the £90,000 threshold may not be registered, but voluntary registration brings the same digital record duties.

Can Amazon and eBay VAT reports replace accounting software?

No. Marketplace reports are source records. You still need digital records, adjustments and an MTD-compatible filing route.

What evidence should I request from a software provider?

Request a mapping document, sample VAT entries, an audit trail, HMRC recognition and a test using your own marketplace reports.

Is product research software enough for VAT?

No. Product research supports sourcing and pricing. It does not keep VAT records or file returns.
