Your client approval workflow
Track your work
Capture every hour, fixed-fee task, and billable detail the moment it happens. Otterflow keeps the work log organized by client and project, so review day starts from a clean record instead of a late-night spreadsheet cleanup.
Take a tourTurn it into a client-ready review
Turn raw entries into a polished client review with clear sections, readable notes, and totals that explain what was done. The client sees context before the invoice, not a vague list of line items after the fact.
Take a tourGet approval before you invoice
Share one secure review link and give the client a focused place to approve, question, or request changes. The decision happens before billing, which keeps expectations clear and removes the usual email thread around what is ready to invoice.
Take a tourGenerate the invoice instantly
When the review is approved, the invoice is already aligned with the accepted work. You can move from approval to billing with consistent details, fewer manual edits, and a cleaner handoff from completed work to payment tracking.
