Off-the-shelf or custom software: how to decide
Buying is usually faster and cheaper to start. Building is usually better where the process is genuinely yours. Most businesses need both, so the real skill is drawing the line in the right place.

Buy for the common, build for the distinctive
Accounting, payroll, email and general CRM are solved problems; paying for them is almost always correct. Build where a process is how you actually compete, or where the available products force you to work in a way that costs you customers.
Costs each option hides
- Off-the-shelf: per-seat pricing as you grow, integration work, workarounds, migration if you outgrow it
- Custom: ongoing maintenance, hosting, security updates, and the need for someone to own the roadmap
- Both: training, data migration and the time your team spends changing how it works
A middle path that often wins
Buy the commodity systems, then build a thin custom layer where your process is different — a booking flow, a quoting tool, a client portal — connected to what you already own. It keeps the build small and the value obvious.
