The software arm of Proactive IT
We build software of every kind
and rebuild what you already run.
Custom applications, legacy systems modernised, AI built into the tools you use every day, and automation across the software you already pay for. Web, mobile and multi-tenant platforms, from one team in Colombo.

What we build
If it runs the business,
we can build it or rebuild it.
Nine kinds of work, one team. Most engagements start as one of these and quietly become two or three, which is the argument for having them under one roof rather than three suppliers.
Custom software
Applications built around how your business actually works, not how a package thinks it should.
- Internal tools, portals, dashboards and line-of-business systems
- Desktop, web and mobile, or all three against one backend
Legacy modernisation
Old, slow, unsupported software rebuilt on current technology - without losing what it knows.
- Access, VB6, Delphi, classic ASP, legacy PHP and unsupported frameworks
- Data migration with reconciliation against the system being replaced
AI inside your software
Applications that read, summarise, classify and answer - instead of only storing and displaying.
- Document and invoice extraction, straight into your existing records
- Classification, routing and triage on incoming work
AI automation
The repetitive work between your systems, running on its own and showing what it did.
Websites & web platforms
Fast, accessible sites and customer-facing platforms that do more than sit there.
Mobile apps
iOS and Android apps for people who are on their feet, not at a desk.
SaaS platforms
Multi-tenant products with plans, billing and onboarding - built to be sold, not only used.
Software redesign
Same system underneath, rebuilt on the surface so people stop dreading it.
Systems integration
Your separate systems connected centrally, so a number is entered once and appears everywhere.
Legacy modernisation
The system that runs your business
is fifteen years old. That is not a mistake.
It is an asset with a maintenance problem. Everything the business knows about how it works is encoded in there, and most rewrites fail by throwing that away along with the technology. We keep the first part and replace the second.
What we usually find
- A spreadsheet, or a database somebody built in the nineties, quietly running a core process
- One machine in one office that the whole thing depends on
- A vendor who stopped supporting it - or stopped existing
- Reports exported from one system and typed into another
- Rules nobody can explain, because the person who wrote them left
What you get back
- The same rules, on technology that will still be supported in ten years
- Reachable from a browser and a phone, wherever the work actually happens
- Your data migrated and reconciled against the old system before anyone signs it off
- Screens that answer immediately, on the connection you actually have
- The logic written down as it is rebuilt, so it stops being folklore
Both run, briefly
The old system stays available while the new one takes over, so the business is never betting a day on a single switch being flipped correctly.
Reconciled, not just copied
Migrated records are checked against the source and the differences explained. A migration nobody verified is a rewrite with extra steps.
Yours at the end
The code, the database and the documentation belong to you. If you replace us afterwards, the next team can pick it up.
Selected work
Four systems
running real businesses.
Not concepts or pitches. Each of these is deployed and used daily, and one of them can be opened and clicked through right now.

How it runs
Nobody signs anything
before we have looked.
The infrastructure side of Proactive IT opens with a free site survey. This is the same offer for software: someone comes and looks at how the work is really done, writes down what they found, and gives it to you whatever you decide next.
- 01
Discovery session
We sit with the people who use the system and watch them work. No charge, no obligation, and nothing to buy at the end of it.
- 02
Written scope
What we found, what we would build, and what we would leave alone. In writing, and yours to keep - including to take to somebody else.
- 03
Build in the open
Short cycles against a working environment you can log into. You see the thing moving rather than a status report about it.
- 04
Launch & keep going
Deployed, documented and handed over with your team walked through it. The number you call afterwards is the same one.
Tell us what
the software has to do.
A system that has stopped keeping up, a process still held together by spreadsheets, or an idea with nothing built yet. We will look at it properly before anyone talks about a quote.
Discovery and written scope - free, and yours to keep
