For Finance teams
Approvals with a name, a timestamp and a diff
Replace approval threads in email and chat with apps that route each request to the right person, show exactly what will change, and record the decision. Approvers can act in the app or straight from Slack.

The right approver, every time
Route by amount, region, team or risk score. Requests above a threshold go to a second person, and nobody can approve their own request.
The change, not a summary
Approvers see a diff of exactly what will change, with the record's history beside it, before they press Approve.
A record auditors can use
Each decision stores who asked, who approved, when and what changed, and exports from the Logbook in one step.

Approval flows teams moved out of the inbox
03 — What it includes
Built for the approver as much as the requester
Routing rules in plain English
Write "refunds over $500 need a team lead" and Chamfer builds the routing, the threshold and the check.
Two-person rules
Require a second approver above any amount, and stop people approving their own requests.
Approve from Slack
Approvers get the request with the details and two buttons, and the decision is logged under their SSO identity.
Reminders and escalation
Requests that sit too long remind the approver, then move to a backup after the time you set.
Delegation with limits
Approvers on leave hand requests to a named delegate for a set period, and the Logbook shows who acted for whom.
Exportable history
Filter decisions by approver, amount or date and export them for audit as CSV or JSON.
