How it works

Everything you need to get approved faster

Build templates once

Define fields, approvers, and expiry rules. Reuse across your team.

Send in seconds

Submit requests from any template. Approvers get an email instantly.

One-click approval

Approvers approve or deny directly from email — no account needed.

Stay in the loop

Real-time status updates. Automatic reminders on expiry.
