How online booking works in a mobile app

First-release scope

Customers select a service, professional and time. Availability depends on duration, breaks, working hours and existing appointments. The server checks again when confirming because another customer may have just taken the same slot.

How to verify the result

Show rescheduling and cancellation rules before confirmation. Account for the location’s time zone, changed durations and repeated taps. Customers should see the current appointment status; reminders should open the specific booking rather than a generic home screen.

What to prepare

Describe your current process, number of locations, required languages and main customer journey. Agree what belongs in the first release, what needs separate estimation and how you will accept the result.

First, define roles, the source of truth, payment and cancellation rules, and repeated actions. Test failures and network loss separately. A tap alone must never confirm a payment or appointment.

Plans and next steps

Start is €79/month and Business is €149/month. Launch is included in both plans. Complex features, migrations and third-party subscriptions are assessed separately after agreeing the brief.
