Questions that arrive answered
Instead of "can you look into the 18,250 vs 18,200", you receive: the invoice (page 1), the bank statement line showing the 50 fee (page 3, line 14), the agreement clause saying the payer bears charges, and the entry. Your job becomes approving, not investigating.
When you disagree
Genuine disputes — a recharge you believe is outside the agreement, an allocation key you read differently — are summarised with both sides' evidence and go to the controllers to decide. The agent does not pick a winner.
Nothing touches your ledger
Entries are drafts. You post them in your system, or you don't.
