Now that you’ve learned how to register or reserve any purchased item from your inventory, it’s time to generate your first product receipt. Creating receipts is important and informative, as it confirms your customers have received your products. Receipts also allow you to process your purchase order lines (POs) for invoicing. Make no mistake, you can gather an amazing amount of information from receipts – if you know what to look for. After you generate the product receipt, the system creates an unchangeable voucher document.
