Card Payments

EPOS systems explained

A basic card terminal only takes payment. An EPOS (Electronic Point of Sale) system replaces the till entirely, tying sales, stock and staff records together in one place — useful once a business outgrows a simple terminal.

Key points
  • EPOS = till + stock + reporting + staff management, not just card payments
  • Cloud EPOS is cheaper to start; on-premise suits high-volume sites needing offline resilience
  • Best value for stock-heavy or multi-site businesses, not simple single-till setups
  • Confirm it integrates with your card terminal and accounting software before signing up

What does an EPOS system add to a card terminal?

Real-time stock deduction on every sale, product-level sales reporting, staff clock-in/permissions, and till-side refunds/voids — none of which a standalone card terminal tracks.

Cloud or on-premise EPOS: which is better?

Cloud EPOS (iPad/Android-based) syncs sales data online and is cheaper to start with. On-premise systems suit high-volume sites needing to keep trading through an internet outage.

Does your business need an EPOS system yet?

A single-till shop with simple stock can outgrow a card terminal fast. Multi-site, high-SKU or stock-heavy businesses (retail, hospitality) see the clearest return.

What should an EPOS system integrate with?

Check the EPOS integrates with your existing card terminal or acquirer, and exports cleanly to your accounting software — re-keying sales data manually defeats the point.
