Custom software or off-the-shelf product: how to decide without regrets
Four questions to work out whether your company needs custom software or an off-the-shelf product is enough, and what a wrong call costs.
Most companies reach the same question late: do we keep adapting the tool we have, or build the one we need? The answer is rarely “always custom” or “always off the shelf”. It depends on four things.
1. Is your process a competitive advantage, or the same as the whole sector’s?
If you invoice, clock hours or run a warehouse like any other company, an off-the-shelf product will do and cost less. Custom software pays off when the process is what sets you apart.
2. How much manual work does today’s workaround carry?
Spreadsheets bridging two systems, weekly exports and “just in case” reviews have a cost that is almost never in a budget. Measure it in hours per month before comparing prices.
3. What happens if the vendor changes the terms?
With an off-the-shelf product you depend on its roadmap and pricing. With custom software you depend on having documentation and a team to maintain it. Neither dependency is free; pick the one you control best.
4. What does a wrong call cost?
Starting with a bounded part, in production and with real users, reduces the risk. If the first delivery does not fit, you find out in weeks, not in a year.
A practical rule
If two of the four answers point to “custom”, an hour’s conversation is worth it. If not, you probably just need to configure what you already have better.
