Best POS Systems for Resale Stores in 2025

If you run a resale, consignment, or thrift store, you’ve probably noticed something frustrating: most POS systems aren’t built for secondhand retail. They’re great at handling transactions, but they don’t manage consignor splits, track single-SKU items, learn from historic pricing data, or automate communication. In this guide, we’ll cover the best POS systems for resale stores in 2025, their strengths, and how to turn them into fully automated resale platforms.

Why POS Systems Alone Aren’t Enough for Resale

A standard POS system can:

  • Process payments
  • Track inventory in bulk
  • Manage basic reporting

But resale and consignment stores need more:

  • Consignor management — Tracking items per seller, calculating commission splits, and automating processes throughout the item lifecycle.
  • Branded consignor portal — let your customers see the status of their items and how much they earned. Payout requests and booking new deliveries can be done directly in their portal.
  • AI pricing — Pricing secondhand goods for a fast, profitable and high sell-through rate.
  • Item-level tracking — Every item is unique, with its own history and price changes.
  • Automated seller communication — Reminders, sales notifications, and payout updates.
  • Multi-channel syncing — Avoiding double-selling between your store and online channels.
  • Multi-location support — Add as many locations you want, and track you consignors across different stores
  • Bookings and delivery schedules — Set custom delivery schedules for each store and let you consignors book a time slot directly in the system
  • Advanced analytics — Get real-time information about how your stores perform

Without these features, most resale stores end up using spreadsheets, manual calculations, or extra staff time, all of which slow growth.
