This is the credit book: who owes how much, and their last movement. The owner sets a limit for each customer; Rafeeq warns you as they near it, and past the limit a credit sale needs approval.
Press any step (or scroll) and the phone shows its screen.
Open the customer from «Credit», tap «Limit» and type the amount. A flag appears as they near it, and past the limit a credit sale needs your approval.
Open the customer, tap «Collect payment» and type what they paid. It comes off their debt right away, and the amount goes into your drawer.
Rafeeq suggests who is due a reminder, and with one tap you send it to the customer on WhatsApp. You turn automatic reminders on from «More → Settings».
Yes, open the wrong entry in the customer's book and tap «Cancel». The entry isn't erased; it stays crossed out in the log so everything remains clear.
