Why business software ages: technical debt made simple
In year one the software works beautifully. By year three every change takes weeks. By year five someone suggests “rebuilding it from scratch”. It happens almost every time, and it has a precise name: technical debt.
What technical debt is
Technical debt is the future cost of shortcuts taken in development today. A quick fix instead of a well-designed solution, an outdated library, a feature added “in a hurry for the trade fair”: each works right away, but leaves a debt to be paid later, with interest.
Like financial debt, it isn’t always bad: sometimes borrowing to move faster is worth it. The problem starts when nobody pays it back.
The symptoms
- Every small change takes far longer than seems reasonable.
- Fixing one problem makes another appear somewhere else.
- The software runs on old versions of languages and libraries that nobody dares to update.
- Only one person really knows how it works, and if they leave, the project stalls.
Why it hits custom software hardest
A product used by thousands of clients has to be maintained: the vendor updates, fixes and refactors. Traditional custom software, on the other hand, is a one-off project. After delivery the budget runs out, maintenance shrinks to urgent fixes, and the debt grows year after year. Not through incompetence, but because nobody has the economic incentive to pay it back.
How to avoid it
Separate what’s common from what’s unique
Much of any management system is the same for everyone: users, permissions, records, calendar, documents, notifications, APIs. If that part lives in a shared platform maintained for all clients, technical debt is paid off once and everyone benefits.
Update continuously, not in big jumps
Small, frequent releases with automated tests cost far less than one big migration every five years.
Keep customisations separate
A client’s specific features should live in distinct modules that talk to the platform through stable interfaces. That way the platform can evolve without breaking what’s custom.
Our approach
That’s exactly why we built GoCRM on CORE: a shared platform, written in Go, that we maintain and update for all clients together. Custom modules stay yours; everything else follows the core release cycle. The result is custom software that doesn’t age.
