Start a clock when a client asks for work outside the agreed scope. Stop it when you stop. See the hours and a suggested extra-fee line you can paste onto an invoice or change note. No account. No fee. Nothing is uploaded.
Not a contract and not legal advice. The fee line is arithmetic from the rate you type. It does not say the client has agreed to pay. Agree the extra in writing if you can. Rounding up is your choice, not a rule.
You type this. The page does not look up a market rate.
