BookBay: an appointment booking SaaS for salons and clinics that works the way small businesses actually run

A SaaS startup wanted to serve salons, clinics and studios that lived on paper diaries and phone calls, where no-shows ate into already thin margins. We built BookBay: online booking pages, WhatsApp confirmations and reminders, deposits to cut no-shows, staff calendars, a simple POS and a multi-branch dashboard — a product small business owners could set up in an afternoon.

BookBay: bookings, reminders and deposits for small businesses.
01

Paper diaries and empty chairs

BookBay's founder had run a chain of salons. Bookings lived in a paper diary at reception; staff answered the phone while cutting hair; and no-shows left chairs empty at peak hours. Existing booking software was built for large chains and was too complex and expensive for most small businesses.

“Every no-show is an hour of a stylist's day that never comes back.”

— BookBay's founder
02

Finding the smallest useful product

We interviewed salon owners, physiotherapists and yoga studio owners. The common needs were simple: a booking link to share on Instagram and WhatsApp, reminders that reduce no-shows, and a calendar staff could see on their phones. Anything that took more than an afternoon to set up would not be adopted.

The MVP
  • Shareable booking page
  • WhatsApp confirmations and reminders
  • Deposits for peak-hour slots
  • Staff calendars on phones

Set up in an afternoon

Owners add services, staff and hours in a guided setup, and get a booking link immediately. Customers book in seconds and receive WhatsApp confirmations and reminders. Owners can require small UPI deposits for peak slots, which reduced no-shows noticeably for early customers.

After the MVP, paying customers shaped v1: a simple POS, customer history, packages and memberships, and multi-branch dashboards.

Decisions we made

Agreed with the founder, prioritising simplicity.

01

Customer app or booking pages?

  • Customers install an app
  • Web booking pages shared by link

Our call: Web booking pages shared by link. Customers book once or twice a month; links on Instagram and WhatsApp worked better.

02

SMS or WhatsApp reminders?

  • SMS
  • WhatsApp with confirm replies

Our call: WhatsApp with confirm replies. Customers read and answered WhatsApp, which reduced no-shows.

03

Deposits for everyone?

  • Deposits on all bookings
  • Owner-controlled deposits for peak slots

Our call: Owner-controlled deposits for peak slots. Owners kept flexibility; deposits where no-shows hurt most.

Checkwise

A founder who had run quality inspections for years wanted to turn his know-how into a SaaS product: configurable inspection forms, offline mobile inspections, photo evidence, automatic reports and corrective-action tracking. We built Checkwise from MVP to a multi-tenant product with billing, SSO and an API — 26 features and the architecture to keep adding more.

Education

Vidyora

A multi-centre coaching group asked us for 'an app'. What they needed was a complete learning platform: AI question papers and answer-sheet evaluation, offline lessons for students on shared phones, parent reports on WhatsApp and one console for every centre. This is the story of how Vidyora went from a whiteboard sketch to 30 features in production.

Fintech

Milaan

A fast-growing D2C brand was closing its books three weeks late because nobody could say which payments had actually landed. We built Milaan, a reconciliation platform that pulls orders, gateway reports, courier COD remittances and bank statements into one ledger and matches them automatically — with 28 features and a finance team that now closes the month in days.
