Quick answer
Choose POS around your sales workflow, stock, peripherals, integrations and support needs. Ask the provider to demonstrate your actual scenarios, including returns, discounts, failed connectivity and end-of-day reconciliation. A feature list is not the same as a working process.
Start with the sector
A restaurant may need modifiers, tables and kitchen routing. Retail may need variants, barcodes and transfers. Laundry may need item tags, order status and partial delivery. List the exceptions that staff currently handle manually.
Test hardware and connectivity
Printers, scanners, cash drawers, displays and payment devices must work with the selected system. Clarify what functions remain available during a connection failure and how transactions reconcile afterwards. Do not assume offline behaviour from a general sales description.
Check stock and reporting
Ask how returns, wastage, transfers and adjustments affect inventory. Review the reports used by the person closing the day. A useful system should make discrepancies visible rather than hide them behind a dashboard total.
Clarify costs and access
Separate software subscription, devices, installation, training, integrations and support. Confirm data-export options and who owns the administrator account. Understand the cost of adding branches or tills before committing.
Run acceptance with staff
Let the people at the counter perform common tasks during testing. Record training gaps and configuration changes before go-live. Plan how they request help during trading hours and which issues require escalation.
