Build vs buy: when should a business build custom software?
A practical way to think about building custom software versus buying an off-the-shelf system — and where legacy modernisation fits in.
Most businesses default to buying an off-the-shelf system, and for a lot of needs — accounting, generic CRM, standard HR processes — that is the right call. Custom software earns its cost when the way a business operates is genuinely specific to it, and no off-the-shelf product fits that shape without forcing the business to change how it works around the software.
When building makes sense
Building is usually justified when a core, differentiating part of the business — the thing that makes it competitive — is being run on a generic tool that was never designed for it, when an existing off-the-shelf system requires so much workaround and manual patching that it has effectively become custom anyway, or when several systems need to talk to each other in a way no vendor package supports out of the box.
Where legacy modernisation fits
Not every "build" decision starts from a blank page. Often the right move is modernising an existing application rather than replacing it outright — keeping what works, and rebuilding the parts that are genuinely holding the business back onto a cloud-native foundation that is cheaper to run and safer to change.
How MSA Technologies approaches it
We design and build the systems that run day-to-day operations — customer-facing applications, internal business tools and the integrations between them — and we say so plainly when an off-the-shelf product or a modernisation of what you already have would serve the business better than a new build.
