When a business sends an invoice, they often list the total amount (e.g. $100) and have fine print to the effect that "If paid by credit card, a surcharge/merchant fee of x% will apply".
Then, when reconciling the expense, I have an invoice for $100 but a transaction total of $100+ x%.
Should I be pushing back on the vendor to amend their invoice to include an exact total for the transaction fee, or is it sufficient to have "something" paying lip service to the existence of a merchant fee if paid via credit card.
