Build custom software, or keep buying SaaS?
Buy when the software is a commodity everyone does the same way — email, accounting, payroll. Build when the software is how you compete: a workflow no off-the-shelf tool fits, or a process that defines your margin. The fork isn't cost — it's whether the thing is differentiating or generic.
Off-the-shelf is the right call.
Don't build what you can rent well.
- It's a commodity — accounting, email, payroll, basic CRM.
- A mature tool fits your process without heavy workarounds.
- It's not how you compete — no advantage in owning it.
- You need it next week — buying is faster to live.
Custom is worth the spend.
- Your workflow is the edge — the way you operate is the product.
- Off-the-shelf doesn't fit — you're paying staff to work around it.
- Your systems don't talk — you need them joined, not bolted.
- Per-seat fees punish growth — renting costs more than owning over time.
The honest brakes.
Don't build to save money on a tool that already works — you'll spend more. Don't build a commodity to feel in control. Don't build if you can't commit to maintaining it. If a good off-the-shelf tool fits, buy it; we'll tell you when that's the answer.
Common questions.
Should I build custom software or buy off-the-shelf?
Buy when the software is a commodity (accounting, email, basic CRM) and a mature tool fits. Build when the software is how you compete — a workflow nothing off-the-shelf fits, or a process central to your margin.
When is custom software worth it over SaaS?
When you're paying staff to work around an off-the-shelf tool, when your systems don't talk to each other, when per-seat fees punish growth, or when your workflow is your advantage and no tool matches it.
When should I NOT build custom software?
When a good off-the-shelf tool already fits, when it's a commodity you don't compete on, or when you can't commit to maintaining what you build. Building to save money on a working tool usually costs more.
Is custom software cheaper than SaaS in the long run?
Sometimes. SaaS per-seat fees and add-on surcharges compound as you grow, so over several years owning a fitted system can cost less than renting one that doesn't fit. It depends on seats, growth and fit.
How do I decide build vs buy?
Ask whether the software is differentiating or generic, whether a mature tool fits without heavy workarounds, and what renting will cost over five years versus owning. If it's generic and a tool fits, buy.
Can I do both?
Yes — most businesses buy commodity tools and build the few systems that are their edge, then connect them. The skill is knowing which is which.
