Case study · Salons & spas

A full diary, and fewer empty chairs

A startup set out to give independent salons and spas the online booking that chains already had. This is how we built a SaaS product where each salon gets its own branded booking page, takes deposits and fills cancelled slots automatically.

A booking product sold to thousands of small businesses.

Expected business outcomes

What the client set out to achieve

Salon owners judge the product by the diary, so the targets were set on bookings and no-shows.

  • 30–50% Fewer no-shows

    Deposits and reminders make a booking a commitment.

    Target range for salons that switch on deposits

  • 40–60% Of bookings made online

    Clients book from the salon's own page, at any hour.

    Target range after three months on the product

  • Under 10 minutes To set up a salon

    Services, staff and hours entered through a guided setup.

    Target for a salon with up to ten staff

Business challenges

Where the client started

Independent salons took bookings by phone and lost them the same way.

Bookings

A paper diary, and calls that went unanswered during treatments.

No-shows

Empty slots with no deposit and no way to refill them.

Marketplaces

Booking marketplaces that charged commission and owned the client.

Staff

Stylists with different services, prices and working hours.

Brand

Salons that wanted their own name on the page, not a platform's.

Proposed solution

What the product covers

Every salon gets the same engine under its own brand.

  • Branded booking page

    Each salon's own address, colours and services.

  • Staff diaries

    Services, durations and working patterns per person.

  • Deposits and payments

    Card on file, deposits and cancellation rules set by the salon.

  • Reminders and waitlist

    Text reminders, and cancelled slots offered to the waitlist.

  • Client marketing

    Rebooking prompts and offers to clients who have not returned.

  • Plans and billing

    Monthly plans by number of staff, with a free trial.

Project requirements

What the client asked us for

The request was online booking for independents. What made it a business was brand and ownership: the salon keeps its clients and its name, and pays a flat monthly fee.

Setup time was treated as a feature. A salon owner sets the product up between clients, so every screen in onboarding had to earn its place.

What the project had to deliver

  • 01The salon's brand, not the platform's
  • 02Deposits that reduce no-shows
  • 03Setup in minutes
  • 04A flat monthly price

Key challenges & considerations

What made it harder, and what we did

  1. Services that need several staff or rooms at once

    What we did

    The availability engine was built to book staff, rooms and equipment together, and tested against real salon diaries.

  2. Payment rules that differ by country

    What we did

    Payment rules were held per country, with deposits and refunds handled by the payment provider's regulated service.

  3. Owners setting up on a phone between clients

    What we did

    The whole setup was designed for a phone first, and timed with real owners until it took under ten minutes.

  4. Peak booking times when every salon is busy at once

    What we did

    The booking engine was load-tested at several times the busiest expected hour before launch.

What we watched for

  • Treat setup time as a feature
  • Get availability rules right first
  • Let the salon own its clients
  • Load test for Friday evening

Development process

The diary first, then everything around it

Pilot salons used the product from the first month.

Quality assurance & deployment

Tested as a product many customers share

A SaaS product is one codebase serving every customer, so a defect reaches all of them at once. Tenant isolation, billing and upgrades were tested as deliberately as the features.

  • Automated unit and API tests, run on every change
  • Tenant isolation tests: one customer can never see another's data
  • Billing, plan and permission scenarios tested end to end
  • Code review by a second engineer before anything was merged
  • Load tests at the expected number of tenants and users

Deployment

  • 01Reminders and marketingTexts, waitlist and rebooking prompts.
  • 02LaunchPilot salons first, then open sign-up.
  • 03Releases without downtimeUpdates shipped behind feature flags, with database changes that can be rolled back.
  • 04Monitoring and warrantyUptime, errors and usage per tenant monitored from day one, and six months of free bug fixing.

Final deliverables

Booked while the salon is closed

Clients book on the salon's own page at any hour, pay a deposit and get a reminder. A cancelled slot is offered to the waitlist before the owner notices it.

The client has a product it can sell at a flat price, with payments and payouts handled for every salon on the platform.

  • A branded page for every salon
  • Deposits and card on file
  • Waitlist that refills cancellations
  • Setup in minutes
