What's the word for getting approval for an invoice? [closed]

Solution 1:

In this context approve means provide authorisation for the required action, not agree with the idea that the invoice should be paid.

Depending on the organisation, approving an invoice could mean a signature on paper, pressing a button on-screen in a computerised accounting system, sending an email, or perhaps just a nod of the head if it is a family business rather than a major corporation.

So you would say to the boss, "Can you please approve this invoice?" After they've signed you could then tell somebody else, "The boss approved this."
