Introduction

MySplitPay is a B2B payment processing platform that manages the relationships between ISOs (Independent Sales Organizations), account representatives, and merchants (MIDs). It handles commission tracking, ledger management, transaction reporting, and integrations with multiple payment processors.

How the platform fits together

Two pictures explain most of MySplitPay. The first is the people side — who manages whom:

One ISO, its reps, their merchants — and each merchant's processing accounts.

The second is the money side. Processor reports become commissions through each rep’s split on each MID, credits and deductions are added alongside, and every rep’s ledger balance is settled by payouts:

Commissions, credits, deductions — and the payout itself — are all transactions; the ledger is their running record.

Every guide in these docs is a closer look at one link in those two chains. The glossary defines each term along the way.

Who these docs are for

• ISOs — managing representatives, merchants, and residual splits.
• Account representatives — tracking commissions and payouts.

Merchants don’t log in to MySplitPay — their ISO and account representative manage everything on their behalf.
