POS Customer Signature in Odoo helps businesses collect customer approval directly during POS checkout. Instead of using paper forms, customers can sign digitally on the screen before completing the order. This makes the billing process faster, cleaner, and more professional. The signature can be saved with the POS order, so store owners have proper proof for future reference. It is useful for delivery confirmation, service approval, high-value sales, repair orders, and customer acceptance. This feature reduces paperwork, avoids confusion, and keeps every transaction more secure. It also gives customers a smooth and trusted shopping experience.
