About
Built in an airport's accounts office, not a sales meeting.
AMM started as the system for one South African airport: a way to get every movement recorded and every fee billed without spreadsheets and retyping. It has run that airport's movements and billing every day since 2003.
A second airport followed. In 2023 we rebuilt AMM from scratch on a modern platform, keeping what two decades of daily use had taught us about how airports really charge: the weight bands, the free parking hours, the monthly accounts, the VAT change that lands mid-month, the operator who disputes a landing six months later.
The rebuild keeps a permanent record of every change, so an invoice can always be traced back to the movement and the person that produced it. It is also why AMM now comes in modules: an airport that only needs a reliable movement log can start there, and add billing, reporting or integrations later on the same records.
