Essential Features for Retail POS Systems
Inventory management is the most critical retail POS feature. You need real-time stock counts, low-stock alerts, purchase order generation, and the ability to manage variants (sizes, colors, styles) without creating separate items for each combination.
Barcode scanning is essential for stores with more than a few dozen SKUs. Your POS should support USB and Bluetooth barcode scanners, and allow you to print custom barcodes for items that don't come with them.
Customer management builds repeat business. Store customer purchase history, create loyalty programs, send targeted promotions, and track customer lifetime value.
Payment flexibility means accepting everything — chip cards, contactless taps, mobile wallets, gift cards, and even buy-now-pay-later options. The more ways customers can pay, the fewer abandoned sales.

Payment Processing for Retail Stores
Processing costs are the hidden variable in POS pricing. Most bundled POS providers charge flat rates (2.6-2.9% + $0.10), which adds up fast in retail.
Unison Payment offers interchange-plus pricing — you pay the actual card network cost plus a small markup. For retail stores with average tickets above $20, interchange-plus typically saves 0.3-0.7% per transaction compared to flat-rate pricing.
On $50,000/month in card sales, that's $150-350 saved monthly — just from better pricing structure.
