01 — Services
Every project starts with a fixed quote. The prices below are starting points — your quote depends on the pages, features and integrations you need.
For getting found on Google and turning visitors into enquiries, calls and bookings.
For replacing spreadsheets, paper diaries and WhatsApp chaos with a tool built around how you work.
For putting bookings, loyalty and ordering in your customers' pockets — on iPhone and Android.
Already launched? I also look after sites and apps after launch — hosting, updates and small changes on a simple monthly plan.

A staff rota and shift scheduling app. Managers build and publish the week's rota; staff see their shifts without another group-chat screenshot.
03 — Why work with me
I'm a Computer Science graduate and full-stack developer. I design, build and launch every project myself — so the person you brief is the person writing the code, and the person you call after launch.

Something else on your mind? Email me at hello@sumhit.dev and I'll reply within one working day.
Websites start from £795, web apps from £3,500 and mobile apps from £5,000. After our call you'll get a fixed written quote — that's the price you pay, unless you decide to add something new along the way.
Most websites take 2–3 weeks, web apps 4–8 weeks and mobile apps 6–10 weeks. Your quote includes a timeline for your project, and you'll get weekly updates along the way.
Yes. Once the project is paid for, the code, design, domain and content are yours. I'll hand over access to everything so you're never locked in.
Yes. Websites are set up so you can change text, images and opening hours yourself, and I'll show you how everything works at handover.
I stay on hand to fix anything that isn't working as it should. If you'd like ongoing hosting, updates and small changes, there's a simple monthly care plan.
Usually, yes. Book a free call and I'll take a look. Sometimes a refresh of a few key pages is enough; sometimes a rebuild is better value. Either way, you'll get an honest answer.
