Knit shipped a brand-new Timesheet API in a week and handed us a ready-to-use NetSuite sandbox. That velocity is priceless when you're running payroll in 40+ countries.

FAQ

Common questions about GigaBook + Invoice Ninja

Is there a pre-built GigaBook + Invoice Ninja automation?

Not yet, but Knit's Integrations Agent can build one — describe what you want and it researches GigaBook and Invoice Ninja's public API docs (or your own uploaded docs) and builds a working automation.

Does this require a pre-built GigaBook or Invoice Ninja connector?

No. The Agent works whether or not GigaBook or Invoice Ninja already has a pre-built connector in Knit's catalog — it researches the real API surface either way.

How long does it take to build?

Minutes to build a first working version, not weeks — you test it against real data before it goes anywhere near production.

Can an invoice be created automatically when an appointment is booked?

Yes, whenever a client schedules a paid session in GigaBook, a corresponding invoice can be generated automatically in Invoice Ninja.

How do customer records stay consistent between appointment booking and accounting?

When a new customer is added in GigaBook, their client profile automatically syncs over to Invoice Ninja for streamlined invoicing and record-keeping.
