As answered by people managing DeveloperToolStack and CallBackApp.co.uk.
CallBackApp.co.uk's answer:
Node.js and Express for the backend, PostgreSQL for the database, hosted on Railway. Twilio handles the calls and SMS, and Stripe handles billing.
CallBackApp.co.uk's answer:
CallBackApp is built specifically for UK tradespeople, not general call centres. It automatically texts missed callers within seconds, and it's aware of context: it knows your business hours and holidays, prioritises genuine emergencies, and recognises known suppliers versus customers so the right automatic reply goes out every time.
CallBackApp.co.uk's answer:
CallBackApp was built as part of a small portfolio of software for UK tradespeople, aimed at a simple problem: a tradesperson mid-job can't answer the phone, and that missed call often just goes to the next business in the search results. CallBackApp texts the caller back automatically within seconds so the enquiry doesn't disappear.
CallBackApp.co.uk's answer:
Most missed-call text-back tools are built for general local businesses or call centres. CallBackApp is priced and built for solo tradespeople and small trade teams: no card required for the 7-day trial, straightforward monthly pricing, and features (business hours/holiday awareness, emergency call priority, supplier recognition) that map directly onto how a plumber, electrician or builder actually works.
CallBackApp.co.uk's answer:
UK tradespeople who are out on jobs and can't always answer the phone — plumbers, electricians, gas engineers, builders, heating engineers, roofers, landscapers and handymen — who don't want a missed call turning into a lost job for a competitor.
