Typical starting point
- A tariff change takes weeks because pricing logic is scattered through the code and nobody knows every place.
- The invoice run happens overnight, occasionally fails, and the cause is not found until the next morning.
- Totals from billing and accounting do not match, and reconciliation is manual work.
What we deliver
- Tariff and contract model in which pricing rules are maintained as data, not code
- Invoice run with restartability, validation steps and a traceable log
- Reconciliation against accounting, incoming payments and dunning
- Migration of existing contracts and history with validation reports
- Interfaces to ERP, CRM, payment providers and customer portal
- Test data and regression tests for every tariff change
How it runs
- Capture of the existing billing logic, including the edge cases only two people know
- Functional concept with data model and validation rules, signed off by the business
- Implementation with a parallel run: old and new invoice runs are reconciled against each other
- Cut-over after confirmed reconciliation, then operations
