What changes

FAQ

Common questions

Do you build custom erp specifically for accounting firms?

Yes. We scope custom erp around the workflows accounting firm teams already use — then replace the spreadsheets and disconnected apps that hold them together. Matters, deals or units live in inboxes and shared drives.

Can accounting firms in Île-de-France use this system?

Yes. We deliver for operators in Île-de-France (France) and the wider region. The system is owned by you, hosted where it fits your compliance needs, and shaped to local handoffs — not a one-size SaaS seat count.

What does a typical engagement look like?

A short discovery on how work moves today, a scoped first release, then weekly delivery until the team is running on the new system. Most first releases land in weeks, not a multi-year programme.

Who owns the software?

You do. Source code, hosting accounts and data are yours from day one, documented at handover. There is no seat licence and no fee that exists only to keep you with us.
