Every booking project starts with the same question: build or buy? The honest answer depends on three things — calendar complexity, payment flows, and who owns the customer data.
Why it matters
Projects rarely fail on technology — they fail on unclear decisions made early and discovered late. Writing the approach down, in public, forces the clarity we want at kickoff.
- Start from the user-visible outcome, not the stack.
- Make the second build cheaper than the first.
- Ship something measurable every week.
The takeaway
Treat this as a starting point, not gospel — every project bends the rules somewhere. The value is in knowing exactly which rule you are bending, and why.
