CRM and sales decision
ConvertLabs
A competent developer can build a useful, smaller replacement (booking, payments, admin calendar) in about a week and low monthly cost, but the complete ConvertLabs product (mobile apps, themes, Airbnb sync, marketing stack, support/community) is larger and not fully replaceable by a one-person DIY effort.
Visit website↗Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Customers book services online → bookings land on a company calendar → providers receive job notifications → payments captured and jobs marked complete.
What it still won’t have
- Native iOS/Android apps (ConvertLabs provides provider apps)
- Turnkey website themes and one-minute site launch
- Airbnb iCal sync / preconfigured reservation-to-job presets
- Built-in email/SMS marketing workflow with analytics
- Priority support, community resources and managed uptime SLAs
What remains hard

First-year cost
Keep paying
Paying is—cheaper in year one.
On cash alone, building overtakes the subscription at 1 seat.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-tenant booking and admin web app using Next.js (React) + Node.js (Express) + Postgres hosted on DigitalOcean. Implement: 1) public booking pages with availability lookup and recurring job setup; 2) scheduling engine that creates jobs and prevents double-booking; 3) Stripe integration for card holds and auto-charge; 4) admin calendar and job list UI; 5) mobile-responsive provider portal that receives push/email notifications and marks jobs complete; 6) basic email notifications via SendGrid. Out of scope: native iOS/Android apps, multi-location enterprise features, Airbnb iCal sync, advanced marketing automation and theme marketplace. Include input validation, error handling, automated tests for scheduling and payment flows, and Docker deployment scripts.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
