Approvals

The right person signs off, before the money moves.

Route each request to whoever runs the account, with a second approver above an amount you choose. Approvals happen in Slack or on a phone, and every decision is recorded next to the charge.

How it works

Rules you set once, followed every time.

Chains by amount

Under $500 the account lead approves. Above it, finance gets a second look. Set different limits per client, per card or per team.

Approve where you already are

Requests arrive in Slack and in the Kestrel app with the client, the budget left and the reason. One tap approves, and the card is topped up straight away.

A record auditors like

Every request, approver and comment sits next to the transaction, so month-end questions are answered by looking, not by asking.
