Do I get a full report of the day by email, and can I get it before closing?

Yes. One PDF for the operating day, by your opening hours and your shifts, counting the POS, the online orders and the QR table orders together, with the delivery apps in the header's total, the shifts one by one, cash and card, discounts, tips, refunds netted out, payment changes with who made them, house accounts owed, the highest bill, the customers who came back and what was carried over. It is emailed to the owners once your closing time has passed and every shift is closed; under Settings → The POS, The full report by email you choose Once a day, After every shift, or Both. Reports → Shifts and the POS builds it at any time with Today so far (PDF) and The day before (PDF). The Reports & insights tab in the docs describes the day report.
