How to solve e-invoice approval by several people?
Short answer
Set multi-level approval according to company rules: amount, center, project, cargo type, supplier or risk. Each step should have a status, a deadline, a substitute and an audit trail.
When is a second signature required?
For example, above a certain amount, with a new supplier or with investment costs.
Order of approval
First physical control, then accounting, then payment approval often makes more sense than parallel chaos.
Do not jam the invoice
If the approver is outside the company, the workflow should have delegation or escalation.
Who approved what
Each step must be traceable, including a comment, time, and any exception.
