FAQ

Common questions about Slack + Better Proposals

Is there a pre-built Slack + Better Proposals automation?

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

Does this require a pre-built Slack or Better Proposals connector?

No. The Agent works whether or not Slack or Better Proposals 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.

How does connecting Better Proposals and Slack improve team productivity?

It delivers key financial updates—like received payments or overdue invoices—directly into Slack channels, so team members can respond quickly without continually logging into Better Proposals.

Can team members initiate accounting steps directly from a message in Slack?

Yes, you can set up workflows so specific chat interactions or file shares in Slack automatically record expenses or create invoices in Better Proposals.
