Bill atthe counter
A billing screen for the shop counter: scan, take cash or UPI, hand over the receipt.

Scan, or type a few letters.
Scan a barcode and the item is on the bill; scan it again and the quantity goes up. No barcode? Type part of the name and pick it. GST is worked out the same way as on any invoice.
Cash, UPI or card, and the change.
Split the payment across cash, UPI and card. OSuite shows the change to give back and records only what was kept, so the cash in the drawer matches the books.
Each sale is a posted, paid invoice to the walk-in customer, or to a named one, and stock goes down at once.
A receipt for the thermal printer.
The receipt opens sized for an 80 mm thermal printer: a short-form GST tax invoice with your GSTIN, ready the moment the sale is done.
