Marketplace apps built for UK tax reporting, split payouts and seller trust.

Sellers register as individuals or companies, and business sellers are matched against Companies House records. The app collects the identity details, tax references and bank information that platform reporting rules require, flags missing fields before a seller can list, and stores evidence of each check with a date so your due diligence can be shown later.

UK rules based on the OECD model require digital platforms to collect seller details, report seller income for each calendar year through HMRC's Platform Reporting Service, and send each seller a copy. We structure orders, fees and seller records so the annual report can be produced from the system rather than reconstructed by hand.

Flat rates, category rates, tiered rates for high volume sellers, listing fees and promotional discounts are configured in the operator console. Each order line records which rule applied, so a seller querying a deduction can be shown the exact calculation and your finance team can test a new fee structure before switching it on.

Holding money on behalf of sellers can bring a platform within FCA payment services rules. Most operators avoid that by routing funds through an authorised marketplace payments provider that splits each card, wallet or pay by bank payment between the seller and the platform. We integrate the provider, payout schedules, reserves and seller balances.

Where sellers based outside the UK sell goods to UK buyers, marketplace operators can be treated as the supplier for VAT on certain sales. The checkout identifies seller location and goods origin, applies the right treatment and keeps the records your accountant needs. We build to the rules your tax adviser confirms rather than guessing them.

A buyer opens a case from the order screen, the seller responds inside a set window, and the operator steps in if they cannot agree. Refunds reverse the commission and the seller payout in one step. Business sellers are shown their duties under the Consumer Contracts Regulations, which do not apply in the same way to private individuals selling occasionally.

Reviews can only be left against a completed order, incentivised reviews are labelled or blocked, and suspicious patterns go to a moderation queue. Messaging and reviews are user generated content, so we also plan the reporting tools and risk records an operator may need under the Online Safety Act and the fake review rules the CMA now enforces.

Restricted categories need extra seller information, recall notices can pull listings across every storefront at once, and buyers can report an unsafe item from the product page. The Product Regulation and Metrology Act 2025 names online marketplaces as duty holders, with detailed duties to follow in regulations, so the controls are built to be extended.

Late dispatch, cancellation and dispute rates are tracked for every vendor. Warnings go out automatically when a seller drifts below your standards, payouts can be held while a case is open, and repeat offenders can be suspended without deleting the order history you may need for reporting or a regulator's question.

Gross sales, commission earned, refunds, pending payouts and reserves are shown per seller, per category and per region. Exports are shaped for your accounting software, and role based access keeps finance, support and trust and safety staff in the parts of the console that match their job.
