Custom software vs off-the-shelf: the honest version.
I sell custom software, and I still tell some owners to buy the SaaS. Here is the actual decision, without the sales pitch.
When off-the-shelf wins
Buy the SaaS when your process is standard, the tool fits without contortions, and the per-user math stays sane. Accounting is the classic case: use QuickBooks, do not build one.
A good platform also carries features you will grow into. Renting a mature product beats building a worse copy of it.
When custom wins
Three signals, and you only need one:
- The workaround tax: your team bends its day around the tool, with spreadsheets bridging every gap
- The headcount tax: per-user pricing has turned growth into a penalty
- The 10% problem: you pay for a platform and use a tenth of it, while the one feature you need is missing
The math, with real numbers
Mid-tier SaaS for a 15-person team commonly runs $100 to $200 per user monthly: $18,000 to $36,000 a year, forever, for rented software. A custom build has its own price, agreed before any work starts, and when it is done you can stop paying me and keep everything, because you own the code and accounts.
The honest caveat: custom needs a builder you trust, and open-ended pricing is where these projects go wrong. Ask any builder for a clear scope and price before you start. You get mine before any work starts.

Is custom software risky for a small business?
The risk is the builder, not the concept. Reduce it with a clear price up front, a plain-English plan before money moves, short delivery cycles, and ownership of code and accounts from day one. That is how I run every build.
Can we mix both?
Most of my builds are mixes: keep QuickBooks and your field platform, add custom glue, dashboards, and the tools they do not make. Replace only what earns replacement.
