Common options to look at

• Square for Retail
  • Works with supported hardware at checkout
  • Can continue selling in limited offline mode
• Lightspeed Retail

  • Offline capabilities may depend on setup/version

What to verify before choosing

• Offline mode scope: can it just ring up sales, or also handle returns, inventory, and customer lookup?
• Hardware support: barcode scanners, receipt printers, cash drawers, card readers, label printers
• Payment processing offline: some systems let you “store and forward” payments, others only allow non-card transactions offline
• Sync behavior: how data reconciles once internet returns
• Device compatibility: iPad, Android, Windows, or dedicated terminals
