- Hosting billed by actual usage, never as a percentage of your revenue
- Infinite scaling without cost spikes
- Total ownership of booking workflow logic
- Monthly bookings
- 10,000
- Average booking value

- SaaS commission
- 3%

Let's discuss how Timerise can help you build and scale your next project.
Built for every industry
Our flexible architecture adapts to your specific business logic, regardless of your sector.
Built in Weeks, Owned Forever
Production-ready booking systems in weeks, not months. AI accelerates, engineers decide. You talk to the engineers who build your system, not account managers.
Project Briefing
Submit your project brief. Our AI immediately analyzes scope and requirements.
Discovery & Strategy
We'll follow up with any additional questions and map your business logic to our AI architecture.
AI-Accelerated Build
AI generates the repetitive code. Engineers focus on the business logic that makes your system yours.
Handoff & Ownership
Complete handoff of the system to your infrastructure. You receive absolute IP ownership and full technical documentation. We don't leave you on your own. Every project includes 3 years of post-delivery support.
Ready to build your booking system with us?
Start by submitting your project brief. Within 48 hours you'll get a clickable prototype of your system and a quote. We take on a few projects at a time, so yours gets senior attention from day one.
The briefing is confidential and secure. Your data stays with us, and everything we build is 100% your IP.
The foundation we build on
Not a product you subscribe to. Battle-tested building blocks, refined over six years of booking projects and assembled into your own system. You own every line.
Core Booking API
The core that powers every booking interaction. Designed for extreme scale and developer flexibility.
Admin Panel
A centralized command center for your entire booking operation. Manage resources, teams, and analytics in one place.
View on GitHubBooking Pages
Convert visitors into customers with a seamless, branded booking experience tailored to your specific workflow.
Services Catalog
A robust, open-source service catalog that allows you to define any business model without limitations.
Your data moves with you
Already on another booking system? Switching shouldn't mean starting over. We migrate your bookings, customers and history into a system you own, even when your current provider offers no export at all.
Source Audit
We map where your data lives and how to get it out: API, native export, CSV dumps or direct database access. You get a migration plan before we touch anything.
AI Data Mining & Mapping
No export, no API? Our AI reconstructs your records from data you already have access to: booking lists, reports or confirmation emails, and maps them onto your new data model, field by field.
Import & Validation
We import into your new system, validate every record against the source and switch over with zero downtime. Your old system keeps running until the numbers match.
Zero downtime
You keep taking bookings during the entire migration.
Full data ownership
Every migrated record lands in a database you own.
Record-by-record validation
Counts and checksums verified against the source before cutover.
One project, one fixed price
You pay once for a complete system. The exact quote depends on the scope of your booking logic and integrations. You get it after a free discovery call.

$15–50k

DXThree ways to run it
Where the system runs is your call. We work in whichever setup fits your organization, and the code stays yours in every one of them.
Your infrastructure, managed by us
The system runs in your cloud accounts, under your contracts and your billing. We set it up, deploy, monitor and keep it healthy.
Your cloudOur infrastructure
We provide the hosting and run everything on our side. Nothing to set up in your organization, and you can take the whole environment over whenever you want.
Our cloudYour servers, your ops team
The infrastructure is already configured by your people. We only build the system and deploy it on what you have.
Development onlyWe build on Supabase and Vercel, and that is the stack we recommend: quick to set up, predictable costs, easy to hand over.
