POS Cart & Checkout

The POS cart is where you build each customer's bill. Search or scroll to add products, adjust quantities (including halves and quarters for weight-based items), select the customer, pick a payment method, and complete the order. WhatsApp invoice and UPI QR code sharing are built right into the checkout flow.

stepByStep

Open a new sale

Tap POS → Sales (or the "+" button on mobile). The sales screen shows your product grid and an empty cart drawer. You can search by product name, SKU, or scan a barcode.

Adjust quantity and quantity multiples

In the cart, use the − and + buttons next to each item. For weight-based or loose items, the quantity step is controlled by the product's Quantity Multiple: 1 = whole units only (e.g. 1, 2, 3), 2 = halves allowed (e.g. 0.5, 1, 1.5 kg), 4 = quarters allowed (e.g. 0.25, 0.5, 0.75 kg). Tap the quantity number directly to type an exact value.

Select a customer

Tap "Select Customer" at the top of the cart. Search by name or phone number. If the customer is new, tap "Add New Customer", enter their name and mobile number, and save. Walk-in customers can be left as "Walk-in" — no customer selection required.

Choose a payment method

Tap "Checkout". Select the payment method: Cash, Card, UPI, or Other. You can choose more than one to split payment (e.g. partial UPI + cash for the balance).

Accept UPI payment

proTips

•Set the correct Quantity Multiple on each product (in the product editor) before using POS — changing it later does not affect past orders.

•For grocery and kirana shops, use Quantity Multiple = 4 (quarters) for items like ghee, pulses, and oil sold by fraction of a kg.

•Always save the customer's WhatsApp number when adding them — this makes the "Send Invoice" step one tap instead of typing a number every time.

•The UPI QR code includes the exact amount due, so customers cannot accidentally pay the wrong amount.

•Use "Other" payment method for credit/advance or cheque payments — add a note in the order to track the payment mode.
