Integrations
Connect approvals to your accounting system.
Otterflow connects time tracking, client approval, and invoicing with accounting software. Billy is available now, with Dinero, Visma e-conomic, Xero, QuickBooks, and more integrations planned.
Live accounting link
Your accounting system owns the invoice. Otterflow mirrors it.
When an accounting integration is connected, invoice drafts created from approved work are created in the accounting system and mirrored back into Otterflow for follow-up.
Bookkeeping-ready workflow
Built to fit the systems that handle your invoices.
If a client or accountant asks how invoicing through Otterflow fits with bookkeeping, the answer is simple: Otterflow is the approval workflow, and the connected accounting software remains the place where the accounting invoice is created and managed.
The accounting provider remains the legal invoice and bookkeeping system.
Billy invoice drafts are created from Otterflow instead of being recreated by hand.
Provider invoice numbers and sync status are mirrored back into Otterflow.
Otterflow keeps the approval trail, work log, review, and payment follow-up together.
Workflow
From time tracking to accounting without rebuilding the invoice.
Otterflow is not a separate billing island. It connects the work log, approval step, invoice draft, and accounting system so freelancers can keep the client workflow clear while keeping bookkeeping where it belongs.
