I work for a big corporation and I’ve seen payments for external vendors take 6+ months to go through due to the layers of approvals. The people who ultimately click Approve are so far up the chain they have no idea what the money is for, so they’ll ignore it until it gets brought up several times, then have to schedule a meeting to discuss it (even though the work’s already been completed), then push the meeting back due to a conflict, then push the meeting back because someone’s on vacation, then forget about the whole thing, then the person who managed the project leaves the company and a new person comes in and has no idea what the payment was for. Then the vendor asks about it and the whole process starts again. Once it gets approved it probably still sits around in someone else’s inbox in the finance department. Oof.
