Complete an Auto-Posted Sale
POS completes invoicing, posting, stock deduction, and payments as one connected operation.
Prepare the cart
Start from an open session, select the customer, and add at least one item with unit, quantity, and price. A discount, tax, and item warehouse can also be set.
- Quantity must be greater than zero.
- The session warehouse is used unless another is selected.
Calculate and post
The system calculates lines and totals, creates the invoice with receipt identifiers, and posts it directly without a draft stage.
- Posting creates the revenue and tax entry.
- For tracked products, it creates the cost entry and deducts stock.
Record settlement
Payment can be split across cash, card, or check. Those payments are created and posted, while any credit portion remains due from the customer.
- A reference can be retained for card or check payments.
Transaction integrity
Invoice creation, posting, inventory, and payments run as one unit; if any step fails, the remaining changes are not kept.
- Selling from a closed session or another cashier's session is not allowed.
