Buy the standard answer when the problem is standard
If an established product handles the requirement well, can be adopted quickly and does not force the business into damaging compromises, buying is usually the sensible choice. Payroll, basic accounting and general collaboration are rarely good reasons to commission a new platform.
Custom becomes valuable when the process matters
Building software is more likely to make commercial sense when the way your organisation works is genuinely different or when the software itself creates a product, service or competitive advantage.
- Important processes are being forced through spreadsheets and manual workarounds.
- Existing products cannot support a valuable customer or operational experience.
- Several systems need to work together and the gaps are creating cost or risk.
- Licence costs increase sharply with growth but the product still does not fit.
- Owning the product, roadmap or intellectual property has strategic value.
Compare total cost, not just build cost
The price of custom software is visible because it appears as a project. The cost of unsuitable off-the-shelf software is often spread across licences, duplicated work, manual administration, missed sales and delayed decisions.
A fair comparison should include the cost of the current process, the value of the opportunity, ongoing ownership and how easily each option can change as the business develops.
Start with the smallest valuable version
Custom does not need to mean a large programme. Define the commercial outcome, prove the riskiest assumptions and build the smallest useful version first. That gives the business evidence before it commits to wider investment.
