A business with a problem asks whether to buy software or have it built. Custom development firms have an obvious incentive in answering that, so treat what follows accordingly — but the honest position is that a large share of the enquiries we receive describe problems a configured product solves better and cheaper. Recommending against a build is occasionally the right recommendation, and firms that never do it are not giving advice.
Buy when the process is one that many companies run the same way. Accounting, payroll, email, helpdesk, standard CRM, project tracking. A product has been refined across thousands of customers, receives updates when the law changes, costs a fraction of a build, and works next week rather than next quarter. Building your own version of a well-served category means paying to reinvent something and then maintaining it forever, and the maintenance is the part that is never in the business case.
Build when the process is genuinely yours — when it encodes how you compete, when no product fits because your workflow is unusual for good reasons, or when the systems it must connect are specific to you. Also build when the product you would buy is priced per user and you have many users doing light work, which is a common Indian situation where the per-seat model breaks the economics of an otherwise sensible purchase.
The middle answer is usually the correct one and gets overlooked: buy the platform, build the difference. A configured product handling the standard eighty per cent, with custom work for the part that is actually yours, delivered through the product's extension points rather than by modifying it. That preserves your upgrade path, costs a fraction of a full build, and puts your engineering effort where it differentiates rather than where it duplicates.
Watch for the two failure modes at either end. Buying a product and then customising it so heavily that it can no longer be upgraded — which strands you on an unsupported version and is the commonest way ERP projects end badly. And building something bespoke because a product lacked one feature, then spending three years maintaining a system that does everything the product did plus that one thing, worse.
The question that resolves most cases: if this software worked perfectly, would a customer notice? If yes, it touches how you compete and is worth building. If the honest answer is that it would only make an internal process less annoying, buy the cheapest thing that works and spend the engineering budget somewhere a customer will see it.
