"Assumptions"
"Defaults are examples, not recommended deposit amounts."
"Use the same price basis for the invoice and deposit. This tool doesn't calculate tax, refunds, core charges or lawful cancellation charges."
"A captured deposit can still be delayed in funding or disputed later."

"Result notes"
"Investigate a negative customer balance as an overpayment; it isn't an automatic instruction to refund."
"Check repair authorization, deposit terms, account limits and actual funding dates separately."
