How long does it take to build a booking system?
A production booking system takes 4–6 weeks. SmartRent's multi-step booking system was delivered in 5 weeks with availability checking, insurance tiers, and payment integration. It increased booking conversion by 42%. The same approach works for any business that takes appointments, reservations, or scheduled services. See the SmartRent case study.
How much does a custom web app cost in the UK?
Most business apps fit within three service tiers: Starter MVPs from £1,000 (2–4 weeks), full custom apps £2,000–£6,000 (4–10 weeks), and AI or automation add-ons £400–£2,000. Every business is different though - if your project doesn't fit neatly into those tiers, custom scoping is available. All pricing is fixed, no hourly surprises. View full pricing.
