Best Retail POS Software for Ecommerce Businesses

Processing-agnostic POS with enterprise-grade inventory tools and no long-term contracts, from $59 a month.

Editor's takeKORONA lets merchants pick their own payment processor and never locks them into a contract, starting at $59 a month per terminal, per its own pricing page. It holds 4.7 stars on Capterra and 4.8 on G2 from a combined pool of reviewers. The tradeoff is an interface some reviewers call dated next to Square, with terminology that adds a learning curve for new staff.

Open-source point of sale that syncs instantly with Odoo's inventory and accounting apps.

Editor's takeOdoo's One App Free plan gives unlimited users access to the POS module at no cost, a rare offer among point-of-sale tools that usually charge per seat. Every sale updates inventory and accounting in real time across Odoo's 120,000-plus live stores, and the app runs offline in any browser, syncing once reconnected. The tradeoff shows up at scale: reviewers report browser crashes with catalogs over 20,000 products, and customer support is a recurring complaint, with some users waiting weeks for a response.

Cloud POS platform with matrix inventory and serial number tracking for complex, multi-location retailers.

Editor's takeLightspeed handles inventory complexity that basic POS systems can't, including matrix variants and serial number tracking for warranties. It processed $90.7 billion in transactions in fiscal 2024 and counts NASA's Langley Research Center among its clients. The catch is a reported $400-a-month fee for merchants who choose a payment processor other than Lightspeed's own.

Free all-in-one POS software with flat-rate processing, built-in PCI compliance, and no monthly fee.

Editor's takeSquare eliminates the usual startup costs for a small merchant: the core POS software is free, PCI compliance is handled automatically, and a magstripe reader ships free with signup. In exchange, transactions run a flat 2.6% plus 10 cents in person, which costs more than interchange-plus pricing at high volume. The most serious documented complaint is Square's fraud algorithm freezing funds for up to 90 days without warning.

Hybrid cloud POS with an offline Always On mode, integrated ecommerce and vendor catalog imports for SMB retailers.

Editor's takeCumulus Retail keeps selling through internet outages thanks to its Always On architecture, a rare feature at this price. Slashdot reviewers note the interface takes training to master, and some report the system logging users out unexpectedly.

Free mobile point of sale with offline mode, plus paid add-ons for inventory and history.

Editor's takeLoyverse gives away a functional POS, Kitchen Display, and Customer Display app, used by more than 1 million companies in 170 countries. The free tier has real limits though. Sales history caps at 30 days, and viewing or exporting older data needs the $5 per month add-on.

All-in-one POS for convenience stores with automated tobacco rebates, EBT processing, and a Boss Revolution sales portal.

Editor's takeNRS turns regulatory busywork into revenue by automating tobacco scan data rebates and bundling EBT and eWIC processing directly into the register. The built-in Boss Revolution portal lets stores sell prepaid phone and bill-pay services as an extra income stream. Read the contract closely before signing: early termination triggers a $1,000 per-unit liquidated damages clause, and returns carry restocking fees up to 30% or $350.

Customizable retail management software with deep inventory tracking, built for growing specialty retailers.

Editor's takeRetail Pro's biggest strength is inventory depth, with serial numbers, lot tracking, and multi-currency support built in. That depth comes with an interface reviewers call slow and outdated. Pricing is unusually transparent for enterprise-grade retail software, starting at $119 per month for one user.

Apparel POS with 3D inventory grids and real-time multi-store sync, backed by Global Payments.

Editor's takeHeartland Retail's inventory gridding tracks size, color, and style in a single three-dimensional matrix, a feature built specifically for apparel rather than adapted from generic retail software. Now owned by Global Payments (NYSE: GPN), it carries Fortune 500 financial backing and flat-rate processing at 2.6% plus 10 cents per transaction. Since the acquisition, users report a sharp decline in support quality, with some bugs left unresolved for close to a year, alongside a documented daily BigCommerce sync failure.
