Clockk has supported apps, which give Clockk the ability to extract details from the applications you’re using to determine different projects within the same app. Let’s say you’re a bookkeeper using Quickbooks for a dozen different clients.

Acuity Scheduling alternatives for businesses outgrowing it
The honest read: if you're leaving Acuity because your business outgrew simple scheduling — you need deposits, add-ons, multiple staff and locations, and ideally a booking site you own — Opencals is built for exactly that transition, and pay-as-you-go means it costs nothing until you're earning.
