FAQ

Common questions about Oneflow + Fortnox

Is there a pre-built Oneflow + Fortnox automation?

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

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

No. The Agent works whether or not Oneflow or Fortnox 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.

What's the most common Accounting + E-Sign automation?

Creating an invoice or bill in Fortnox the moment a matching document is signed in Oneflow, so finance never has to manually re-key numbers from a signed PDF.

Can this trigger off a specific contract type, not every signature?

Yes — the Agent can filter on Oneflow's template, tags, or signer fields so only the agreements that actually need an Fortnox entry create one.
