How do I see how many orders came from the table QR codes and how many were delivery?

Open Reports → Monthly statements and download the XLSX. On the Summary sheet, How orders arrived splits delivery from dine-in, with a count and an amount for each, and How customers paid splits cash from the card machine. The PDF carries the same split. Reports → Shifts and the POS shows what the counter took separately from online, with the average counter sale beside the online average. Judge the month on the statement rather than on a day, because one busy Friday of tables tells you very little.
