> A booking system connected to your CRM, ERP, single sign-on and your own app, with an API for every function, so nobody types a booking twice.

A booking feature Timerise builds into custom booking systems its clients own. One fixed project price, typically $15,000 to $50,000, with this feature part of it. Last updated: 2026-10-20.

Bookings are typed into the CRM by hand, and your app cannot book on its own. We build booking systems that connect to your CRM, ERP and sign-on, with an API for every function.

What goes wrong without it:
- Each booking is copied into two or three other systems, and the copies drift apart.
- Ready-made tools offer a few fixed connectors. Anything else waits for their roadmap or costs a middleware subscription.

How we build it, to the client's rules:
- CRM and ERP: Customers, bookings and payments kept in step with Salesforce, HubSpot, SAP or the system you run.
- Single sign-on: Staff and business customers sign in with the company account they already have.
- API for every function: Your developers and your own app can do anything the booking system does.
- Events to other systems: Webhooks tell your other systems the moment a booking is made, moved or cancelled.

Compared with a SaaS tool:
- Connectors. In a SaaS tool: A fixed list of integrations. In your own system: Connected to whatever you run.
- API. In a SaaS tool: A partial API, often on a higher plan. In your own system: An API for every function, included.

Industries that use it:
- Booking systems for banks and financial advisors (/industries/banking)
- Booking systems for coworking spaces (/industries/coworking)
- Booking systems for rental businesses (/industries/rentals)

Case study: Risify's psychotherapy platform got booking with custom API extensions built for how it works. (/case-studies/risify)

FAQ:
- Q: Our CRM is custom. Can you connect it?
  A: Yes, if it has an API, a database we may read or a file export. We agree how before the build starts.
- Q: What does this feature add to the price?
  A: It is part of the one fixed price for your system, and you see it in the quote before the build starts. Most projects cost $15,000 to $50,000 in total, paid once, with no subscription and no commission on bookings.
- Q: Can you add it to a system we already run?
  A: Yes. We build it into a new system or into the one you already run, with its own quote. When the feature has an Agent Skill, your own developers can also build it with the skill.
- Q: Who owns the code?
  A: You do. The code, the data and the documentation are handed over, and the system runs in your cloud account or on ours. Every project includes 3 years of support.
