Technology that simply works

Each year the public authorities prepared their tax rolls and bills with dozens of scripts and a different manual for each one.

• Over 60 named, guided processes, from loading the Land Registry data to closing the financial year
• Every process is simulated first without touching the database, and reconciled with the approved tax roll
• SEPA direct debit batches, payment letters sent by email and reports for the comptroller
• AI review of every simulation to catch conflicts before anything is issued

Every campaign runs through the same procedure, simulated and checked before a single bill is issued.
