Payment Explainers

    Payments has its own vocabulary (settlement, reserves, SCA exemptions, scheme rules), and most of it is never explained anywhere a merchant would actually read it. These explainers cover the mechanics behind the terms, in plain English, so you can read a provider's contract or a processing statement and know exactly what you're looking at.

    Frequently Asked Questions

    What's the difference between an explainer and a guide?

    Our explainers break down a single payments concept (a fee structure, a settlement mechanic, a piece of terminology) in plain English. Guides (in a separate section) walk through a process end to end, like switching providers or preparing for underwriting.

    Why do payment terms matter if I'm not a developer?

    Because the acronyms and mechanics in this section directly affect your approval odds, your cash flow, and your effective cost per transaction. Knowing the difference between net and gross settlement, or what an SCA exemption does, changes decisions you make when comparing providers.

    Do these explainers apply to both UK and EU businesses?

    Most of the mechanics (settlement, reserves, wallet payments, scheme terminology) are the same across UK and EU card schemes. Where a rule is UK-specific (for example, certain SCA thresholds), the individual article calls that out.
