FAQ

Common questions about Harpoon + QuickBooks Online

Is there a pre-built Harpoon + QuickBooks Online automation?

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

Does this require a pre-built Harpoon or QuickBooks Online connector?

No. The Agent works whether or not Harpoon or QuickBooks Online 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.

Why pair Harpoon with QuickBooks Online?

Combining time tracking and accounting ensures that every billable hour recorded by your team flows directly into invoices without manual rekeying.

How are new client records kept in sync between tools?

When a new client or project is created in Harpoon, customer profiles and invoice details automatically sync in QuickBooks Online.
