Why the settlement date is the date that matters
If you invoice 2,400 USDT and the payment lands eleven days later, the dirham value your accountant wants is usually the value on the day the funds arrived rather than the day you issued. USDT tracks the dollar closely, and the dollar-dirham peg is stable, so the two figures are rarely far apart — but 'rarely far apart' is not a policy.
Pick a convention, write it down, and apply it to every stablecoin invoice. Reconstructing rates months later, invoice by invoice, is the kind of task that turns a quarter-end into a weekend.
