Can the day's figures come to my WhatsApp when the shift closes, in my own words?

Yes. Under Settings → The POS, WhatsApp summary after closing, tick Send the summary after closing and list up to five numbers. After every shift is closed, or closed automatically, the day so far goes from your restaurant's own WhatsApp number to each of them, usually within five minutes. Write the message yourself with names in curly brackets such as restaurant, date, total, dine_in, online, apps, cash, card, closing_cash, tips, discounts, highest_bill, repeat_list and unmatched; a line whose figure has nothing to show is left out. Go back to the standard message restores ours and Show today's message so far previews it with today's figures. A number that has never chatted with your restaurant's WhatsApp gets it once it sends you one message. The POS and the counter tab in the docs covers the summary.
