# SPI (Standard Payment Institution)

https://www.uniwebpay.com/glossary/spi/

*Last updated: 2026-08-03*

The lower of the two Payment Services Act licence tiers, for institutions below the volume thresholds that trigger MPI status. It is a real licence, not a lesser one in kind — but the tier is worth reading off the register rather than off a homepage that says only "MAS licensed".

## Why it matters to a merchant

An SPI is a real licence and a smaller one, bounded by transaction and float thresholds. For a merchant the practical question is whether their own volume, or the volume they expect in two years, sits comfortably inside those bounds — a provider that has to change licence class as you grow is a migration you did not plan for.
