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 EPOS adds

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 vs on-premise

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.

Do you need one 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.

Integration

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.
