I have an idea for an app

From a sketch to something real people can sign into and use.

People usually mean things like: Build my SaaS idea Β· An internal tool for my team Β· A booking system

Start here

Whole projects. Answer a few questions, see a real range, then get quotes from developers who have done it before β€” no account needed to ask.

A web app people sign into

Accounts, data and the thing your product actually does. The first version, built to be added to rather than thrown away.

  • Sign-up, sign-in and password recovery that hold up
  • A database designed for what you are actually storing
  • The core screens your product needs to be useful
€8,000–€25,000Β· 6–16 weeks

Typical range. Answer a few questions to narrow it.

An internal tool for the team

The spreadsheet everyone edits at once, turned into something that cannot be broken by a stray paste.

  • The screens your team uses every day
  • Accounts and permissions per role
  • Import of what is in the spreadsheet today
€5,000–€14,000Β· 4–10 weeks

Typical range. Answer a few questions to narrow it.

Bookings and appointments

People book a time themselves, you stop playing email tennis, and nobody gets double-booked.

  • Availability rules that match how you actually work
  • Booking, rescheduling and cancellation without emailing you
  • Reminders by email, so people turn up
€4,000–€11,000Β· 4–9 weeks

Typical range. Answer a few questions to narrow it.

Add AI to what we already have

A feature that answers from your own content or documents β€” with the cost, the accuracy and the failure modes worked out before launch.

  • The feature, in your product, in your design
  • Answers grounded in your data rather than invented
  • A cost ceiling, and caching so it is not hit twice for the same question
€5,000–€16,000Β· 3–10 weeks

Typical range. Answer a few questions to narrow it.

Or a specific job, if you already know what you need
