A bookable calendar
Services, durations, staff members and working hours. A slot exists only if the staff member and the service both fit in it.

This is an example build. HumansOfCoding is a new studio with no client work to show yet. This page describes how the project would be scoped and built — the same thinking you would get on a real one. Nothing here is a past client, and no number on this page is a result.
THE SITUATION
What's actually broken.
A salon, clinic or studio books appointments over WhatsApp and by phone. Double bookings happen. No-shows are absorbed silently. The front desk cannot take a booking and serve a walk-in at the same time.
This is the clearest example of what an MVP is for. The whole thing is small enough to be genuinely useful in a few weeks, and every week it runs teaches the owner something they would otherwise have guessed at.

VERSION ONE
What we'd build first.
Every item here earns its place by being something a real user would miss on day one.
Public booking page
One link, shareable on Instagram and WhatsApp. No app to install and no account to create.
Reminders
A message 24 hours and 2 hours before. This alone typically moves the no-show rate more than anything else in the build.
Deposits
Optional prepayment for slots that get abandoned. Turned on per service, not globally.
Front-desk view
Today at a glance, plus the ability to block time and add a walk-in in two taps.
DELIBERATELY NOT IN V1
What we'd leave out.
Not because these are bad ideas. Because each one is designed better once the first version has told you something.
- Inventory and product sales.
- Staff payroll and commission calculation.
- A customer mobile app. A booking link works better than an app someone installs once and deletes.
UNDER THE HOOD
How it's put together.
- Everything
- One Next.js app — the booking page needs to be public and fast, and the admin side is small enough to live in the same codebase
- Database
- Postgres, with the availability rules enforced in the database so two people cannot take the same slot
- Reminders
- A scheduled job plus a WhatsApp or SMS provider
- Payments
- A gateway, for deposits only
HOW IT RUNS

BEFORE YOU START
Worth knowing.
This is the shape of build that starts at ₹20,000. What moves the price is the number of staff-and-service rules, whether payments are involved, and how much of the existing customer list has to be imported.
MVPs start at ₹20,000*. Final pricing depends on features and project scope. Third-party costs — cloud hosting, domains, external libraries, APIs, app-store fees and any other paid service — are billed separately and are not included.
