How much does it cost to build a booking app?

What drives the price of a booking app, what to cut for a first version, and when to buy a ready-made tool instead.

The short answer

How much does it cost to build a booking app?

A custom booking app costs whatever its scope costs, and four things set the scope: how many kinds of user it has, whether it takes payment, what it must connect to, and how many platforms it runs on. Our first versions start at from $15,000, fixed once scoped. A ready-made booking tool is often cheaper.

The four things that set the price

Kinds of user. Customers only is simple; customers plus staff plus an owner dashboard is a different size of job.
Payments. Taking a deposit or full payment adds careful work, because mistakes there cost you customers and money.
Connections. Syncing with a calendar, accounting tool or existing database often takes longer than the screens do.
Platforms. One web app costs less than a web app plus a phone app, because each is its own build.

What to cut for a first version

Start with the booking itself: pick a time, confirm, remind. Leave out loyalty schemes, reports and a phone app until the booking flow has real use. A smaller first version is faster to launch, and real bookings tell you which extras are worth building.

Ask any bidder to list what is included and what is not. A price with no scope attached moves later. The app development cost page shows how market rates are reported and how to read them.

When to buy instead of build

If you run appointments in a common way, a ready-made booking tool can be live this week for a monthly fee. Build custom when your rules are the point, such as unusual pricing, scarce resources, or a customer experience competitors cannot copy with a template.

Our prices are on the price list. A new build starts at from $15,000, and a written read of an existing booking app before you commit to a repair is a Ship Check at $299. Keeping a finished app monitored and patched is $500/mo.

FAQ

Straight answers

Is a booking app cheaper than a full web app?

It can be, because the scope is narrower. The price still follows users, payments and connections, so a booking app with deposits and staff accounts is not a small job.

Can I start with a no-code tool and move later?

Yes, and it is often wise. Keep your customer data exportable, and move to custom only when the tool blocks something that matters to the business.

What does it cost after launch?

Hosting, updates, security patches and fixes continue. Ask every bidder for the after-launch number in writing. See application maintenance for what to expect each month.

How long does a first version take?

It depends on scope. Ours are scoped and fixed before work begins, with the timeline written into the scope. Ask for a date tied to named deliverables, not a vague estimate.
