Simple by design

From inbox to books, without the chase.

flow handles the repetitive hand-offs so your approvals stay accountable and your accounting stays current.

Send or upload

Vendors email invoices to a dedicated address, or your team uploads them directly.

Approve with context

flow extracts the details, routes the bill by your rules, and escalates anything that gets stuck.

Sync to QuickBooks

Approved bills post to QuickBooks Online with the original document and a complete audit trail attached.

Built for real operations

Your approval process, finally visible.

flow gives every invoice a clear owner, a deadline, and a history. Whether your process is one approval or several, the next step is always obvious.

Automatic extraction
Vendor, invoice number, line items, tax, totals, and due dates — no manual data entry.

Rules that fit your team
Route by project, class, or supplier through the approval steps your business actually uses.

Audit-ready records
Every approval, rejection, edit, and comment is captured in order for each invoice.
