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 Oneflow + Sellsy

Is there a pre-built Oneflow + Sellsy automation?

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

Does this require a pre-built Oneflow or Sellsy connector?

No. The Agent works whether or not Oneflow or Sellsy 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 should I integrate Sellsy with Oneflow?

Integrating both tools automates contract delivery during sales negotiations and updates sales pipeline stages instantly when agreements are signed or declined.

Can signed documents automatically mark deals as won?

Yes, completing a document signature in Oneflow can instantly update the corresponding opportunity stage to won in Sellsy.
