Short answer
To set up a grocery POS, first choose the correct business country, currency and tax settings. Then add a clean item catalogue, test scanner input, print an invoice and reconcile test payments. Inventory, counter shifts, paired lanes and customer QR baskets can be added incrementally after core billing is trustworthy.
Begin with configuration that affects every sale
Confirm location, currency, tax mode, receipt identity and required invoice information. These settings should be reviewed before registering real transactions because the customer’s receipt is a financial record.
Load and validate the item catalogue
Start with familiar packaged goods and produce. Check units, category, sellable status and barcode uniqueness. For products without a barcode, choose a quick search label that cashiers recognize.
Test real-world tender and refund cases
Run a cash bill, an external card bill, a split tender and a controlled return. Review the sales split and financial reports to confirm the results match the supporting receipts.
Make inventory optional until it is accurate
Receive sample stock, perform a sale, then verify Total Stock. Only use Shelf Stock if the team can physically count and refill shelves. Never assume a software quantity is the same as a fresh physical count.
Introduce customer QR flows last
Print one demonstration shelf QR, build a Digital Basket and load it at the cashier via checkout code. Verify the customer’s total matches the bill, including relevant tax.
| Stage | Successful check |
|---|---|
| Business | Correct local currency and tax mode |
| Products | Unique identifiers and correct sale units |
| Checkout | Matching basket, bill and printed invoice |
| Reports | Gross sales, refunds and net totals reconcile |
| Customers | Customer links and credit balances reconcile |

Questions store owners ask
Should I enable all features on day one?
No. Enable optional workflows only when the staff have tested them and they address a clear store need.
