Peazy: complex calculation rules turned into reliable payslip software

IT consultancy and backend development for accounting software that turns intricate calculation rules into flawless payslips.

Payroll is full of rules: collective agreements, allowances, deductions, pensions and tax brackets that play out differently in every situation. Peazy translates those complex calculation rules into software that automatically produces correct payslips. Reemo contributed at the level of IT consultancy and built, mainly backend-oriented, the engine that reliably computes all those rules.

Calculation rules that must always be right

A payslip that's slightly off is not an option. We modelled the calculation rules to be transparent, testable and maintainable, and built the backend that applies them consistently, no matter how exceptional the situation.

Backend-oriented, with consultancy around it

Besides building, we advised on architecture and data modelling: how do you keep calculation rules manageable when they keep changing? The result is a backend that grows with new regulation without the house of cards collapsing.
