Legacy system modernisation: moving off FileMaker and spreadsheets
Move off the system you've outgrown without stopping the business. We take over what you run today and move you across a module at a time, whether it's FileMaker, spreadsheets, an ageing platform or an AI-built prototype that isn't ready to go live.

The system that got you here won't take you much further.
It works, and people run the business on it every day, but it can't keep up with where the business is going. About half of our work starts exactly here.
The developer who built it is retiring.
The whole business runs on a spreadsheet one person understands.
Our AI-built app works in the demo, but we daren't put customer data in it.
We can't answer the security questionnaire about it.
The four places a move usually starts
How we move you across, a module at a time
A system that's grown for years does a lot of jobs. We take over its support first, then move the one or two jobs the business leans on hardest, with their data, so people feel the difference early and the risk stays small. Everything else keeps running in the old system until its turn.

How the data moves safely
Data is where moves go wrong, so it gets its own plan.
- Every table and field mapped from old to new
- Duplicates and gaps cleaned before anything moves
- Test runs into a copy of the new system, checked with your team
- Old and new run side by side until the figures match
- The old data kept, read-only, for as long as you need it
Systems we've moved people off
Projects where a business moved off a system it had outgrown, or brought an old one up to date.

Questions about moving systems
It depends on the size of the system. The first module is in use in weeks, and each one after it follows from there.
No. The data gets its own plan, tested on a copy before the real move, and the old system keeps running until the new one has proved itself.
Yes, and we usually do. Supporting it first means we know it properly before anything moves.
