What is a Payment Institution (PI) and How Does It Work?

A payment institution is a regulated firm authorised to move money without holding a banking licence. Here is how the model works in practice.

The basics

A payment institution, commonly shortened to PI, is a company authorised by a financial regulator to provide payment services such as acquiring, money remittance, account information and payment initiation. It is not a bank. It does not take deposits and it does not lend the money it holds.

The model exists so that specialist payment firms can operate on their own authorisation rather than sitting permanently behind a sponsor bank.

What a PI can and cannot do

A PI can execute payment transactions, issue payment instruments, acquire card transactions and offer remittance corridors. It can also hold funds for clients, but only in safeguarded accounts held strictly apart from the firm's own money.

A PI cannot pay interest on balances, cannot lend customer funds and, in most regimes, cannot issue electronic money. Firms that need stored value usually look at an e-money licence instead.

Why businesses choose the PI route

Authorisation gives direct scheme and rail access, clearer pricing, and control over the customer relationship. It also raises the bar: capital requirements, governance, reporting and ongoing supervision all apply from day one.

For many growing payment businesses the decision comes down to volume. Below a certain scale, working through a licensed partner is faster. Above it, owning the licence usually wins on economics and independence.
