How to implement split payments: complete guide for marketplace platforms

Implementing split payments on a marketplace platform takes six core steps: provider selection, account setup, seller onboarding, commission configuration, payout handling and testing. Marketplace platforms typically build this on Ryft, Stripe Connect, Adyen for Platforms or Mangopay. Each provider brings different onboarding and compliance requirements. This guide walks through each step in order, from choosing a provider through to going live in 2026.

Step 1: choose a split payment provider built for marketplaces

Not every payment provider supports split payments natively. Some require you to build commission logic and seller payouts yourself on top of a generic API, which adds development time and ongoing maintenance as your seller base grows. Look for a provider that handles split payments, seller onboarding and payouts within one integration, rather than stitching together separate tools for each function. Confirm the provider is authorised to operate in your markets, since only a licensed payment institution can legally hold and distribute funds on behalf of your sellers. Ryft's split payment functionality is built for exactly this, combining provider, onboarding and payout logic in one platform.

Step 2: set up your platform account and seller sub-accounts

Once you have selected a provider, the next step is setting up your platform's master account and the subaccount structure sellers will sit under. Most providers, including Ryft, use a hierarchy where your platform account sits above individual seller subaccounts. This structure lets you track each seller's balance separately while keeping one integration and one dashboard for your team to manage. It also matters for reporting: a clean subaccount hierarchy makes reconciliation far simpler once transaction volume grows across a marketplace or platform business.

Step 3: onboard sellers with KYC checks

Sellers need to be verified before they can receive payouts, using Know Your Customer checks required under UK and EU regulation. This typically covers identity verification, business registration details and bank account confirmation. A strong implementation lets sellers complete this themselves through a hosted onboarding flow, rather than your team collecting documents manually over email. Faster onboarding matters directly to growth, since sellers who wait days for approval are more likely to abandon your platform before their first sale. Our guide to seller onboarding and verification at scale covers this step in more depth.

Step 4: configure commission rules and split logic

This is where you define how each transaction divides between your platform and your sellers. Commission structures vary, and split logic should be configurable per seller, per product category or per transaction type, rather than fixed platform wide. This flexibility matters as your marketplace grows and different seller segments need different commercial terms, from a handful of enterprise sellers to hundreds of small vendors. Ryft supports split payments across 50+ sellers per transaction, with commission rules set independently for each.

Flat percentage commission

A single percentage taken from every transaction, regardless of seller, product or order value. This is the simplest model to configure and explain to sellers, and works well for platforms with a fairly uniform seller base.

Tiered commission by volume

Commission that decreases as a seller's transaction volume increases over a set period. This rewards high performing sellers and can be a useful lever for retention, though it needs more careful configuration and monitoring than a flat rate.

Fixed fee per booking or order

A set fee per transaction rather than a percentage, common in booking and appointment based marketplaces. This model gives sellers cost certainty regardless of order value, which matters most where average order values vary widely.

Step 5: handle payouts, refunds and disputes

Once splits are configured, decide how and when sellers get paid. Some marketplaces pay out per transaction, others on a daily or weekly schedule, depending on cash flow needs and seller expectations. Ryft's delayed and scheduled payment tools support both models within the same platform.

Refunds and chargebacks need to reverse correctly across every party involved in the original split, not just from the platform's share. This is one of the more complex parts of implementation, and it is worth confirming with your provider exactly how disputed funds move before you go live. An escrow layer can help here, holding funds until a transaction is confirmed rather than releasing them immediately.

Step 6: test in sandbox before going live

Before launch, test the full flow in a sandbox environment: seller onboarding, a full transaction split, a payout and a refund. Run through edge cases too, including a seller with an incomplete KYC file and a disputed transaction that needs reversing. Ryft provides sandbox access from the start of integration, so your technical team can validate the full flow before any real money moves.

Compliance requirements for split payments

Split payments involve handling money on behalf of third parties, which brings specific regulatory obligations. In the UK and Europe, this means working with a provider authorised under PSD2, with proper safeguarding of client funds and PCI DSS certification for handling card data. Our guide to PSD2 in 2026 sets out what this means in practice for platforms.

Platforms that build split payments on an unauthorised or improperly licensed provider risk regulatory action, and can lose the ability to process payments altogether. Ryft operates as an FCA-authorised Payment Institution, Licence #972895, with safeguarding and PCI DSS Level 1 compliance built into the platform rather than bolted on afterwards.

Why choose Ryft to implement split payments

The platform combines FCA licensing, real time commission splits and delayed payment tools, so you are not stitching together multiple providers to cover each part of the flow. Ryft's split payment functionality works alongside seller onboarding and delayed payment tools within the same platform, built for marketplace and platform businesses operating across the UK and Europe.
