Want a second pair of eyes before anything is booked? Set up purchase approvals. Open Settings, go to Purchase approval, and switch it on.
Choose how many levels you need: one, two or three. Then add an approver for each level. The buyer approves everything, and finance approves anything over a thousand euros.
Now, a new invoice waits for both approvals. Register stays locked until then. The buyer approves first, then finance.
Now it can be registered, and every step is saved in the audit log. Next up: duplicates, filters and search.
