PSP Switching Reading List
Switching your PSP — or evaluating whether to — is one of the highest-stakes commercial decisions a payment operator makes. The contracts are complex, the exit costs are hidden, and the negotiating window closes the moment you sign. This reading list builds the complete picture: from operating model choice through pricing mechanics, contractual traps, and how to negotiate when you're already locked in.
Who this is for
Payment operators evaluating a PSP migration or benchmarking their current stack, product or engineering leads planning a switch, and CFOs reviewing PSP contracts for the first time.
