Legacy Software Modernisation

Legacy software modernisation rebuilds an old VB, FoxPro or Access system as a web and mobile application. Records from earlier years are extracted and reconciled against your own balances before the switch.

What usually prompts the decision

The machine is failing

Old hardware and an unsupported Windows version are common, and the licence key may be missing.

Nobody can change it

The developer has retired and the source code is missing, so the running program is left untouched. Any change carries risk nobody can measure.

The business has changed shape

A second branch, transport documents or dealer logins were never part of the original design.

How the rebuild proceeds without a stoppage

Data first

Years of masters and transactions are extracted, cleaned and loaded, and every difference between the old figures and the loaded ones is listed for review by your team.

Parallel run

The same entries go into both systems for an agreed period, and totals are compared each day.

Switch by module

Billing moves first and stores follow. The old system stays readable afterwards.

What the new system adds

Access from anywhere

Branch, home and phone can all reach the system, and it no longer sits on one machine in the office.

Roles and history

The system records who edited a rate and when. Old systems rarely kept that.

Links to accounting software and WhatsApp

Journal entries and payment reminders move across without anyone retyping them. Each link is scoped separately.

FAQ

Frequently asked questions

Can our old data be brought across?

Usually all of it, including data from FoxPro, Access or an old SQL database. Records are extracted and reconciled against your closing balances before the migration is signed off.

What if there is no source code for the old system?

That is common and it does not block the work. The database and printed reports show most of the rules, and your staff fill in the rest in the first workshop.

Is modernisation the same as re-engineering?

No. Modernisation replaces the old platform entirely, while re-engineering restructures a system already running on current technology. Which one applies depends on what the software runs on today.
