Wiring Twilio to Zapier to text after a missed call takes an afternoon — it's the nucleus of our entire product, and we acknowledge it. The rest is where DIY erodes: AI qualification that knows your trade, calendar routing with buffers, SMS compliance, resilience when Twilio changes an API on a Friday, and above all time — yours, every month. If you love building, DIY is a great school. If you want recovered jobs, $149 buys the outcome, not the tools.
