CUTE NAME. SERIOUS BOOKING ENGINE.A little more moo.
A little more moo.
A lot more you can do.
Your next offer should be a new service, not a new booking system.
Your bookings. Connected to your business.

Explore the API (beta) ↗React to what happens next.
Eight webhook events cover booking creation, confirmation, rejection, cancellation, rescheduling, attendance and two subscription events.

MAKE THE SWITCH WITH CONFIDENCE
Bring your hardest booking to the trial.
BookThatApp belongs on a rental shortlist when you need to model equipment, staff and locations together. Run a scenario where two services compete for one resource, then cancel and rebook to verify inventory recovery.
For a damage-bond workflow, ask both vendors to demonstrate collection, release and refund handling. A booking deposit and a refundable damage bond solve different problems; the BTA listing explicitly mentions deposits/bonds on Premium.
For a store needing an API, evaluate BTA Business and its documented endpoints. Do not choose a lower tier based on a general integration label. Cowlendar may suit the booking workflow without custom development, but that is a different requirement.
Your questions, answered.
Does Cowlendar have a free plan?
Yes. Cowlendar has a free plan with all features. Usage allowances apply; the pricing page shows the limits and revenue-based paid tiers.
Is Cowlendar cheaper than BookThatApp?
It depends on the features and booking revenue. Use the calculator above: it compares the lowest documented plan for your selected features and shows the assumptions, rather than comparing unrelated starting prices.
Does Cowlendar support subscriptions, an API and webhooks?
Yes. Recurring service subscriptions and bundles are supported. The public API and webhooks are documented as beta, including subscription-credit bookings and eight webhook events. Review the linked API limitations before planning an integration.
When should I choose BookThatApp instead?
Operators with detailed resource rules, bond handling or API requirements. Compare booking volume and staff requirements carefully. Lite is listed for one booking type and 50 monthly bookings; API access appears on Business.
