Choosing the right POS system is one of the most important decisions you'll make as a small retail store owner. Your POS handles transactions, inventory, staff management, and increasingly, customer relationships. The wrong choice can cost you time and money; the right one scales with your business.
This comparison covers three systems popular with small retailers: ParallelPOS, Square, and Clover. We'll break down pricing, core features, ease of use, and which businesses benefit most from each.
Best for: Retail stores planning to scale, multi-location operators, businesses needing integrated back-office tools.
ParallelPOS combines POS, inventory management, team scheduling, payroll, sales commissions, expense reimbursement, CRM, and appointment booking in one platform. It includes a built-in AI copilot to automate routine tasks.
ParallelPOS operates on a monthly subscription model without per-transaction fees. The platform scales from single-store to multi-location operations. View current pricing and plans for exact rates based on your store size and feature needs.
Best for: Solo retailers, pop-up shops, businesses new to POS systems.
Square is the most recognizable POS brand for small businesses. Its iPad and mobile app are intuitive, hardware costs little, and setup takes minutes. Square Payments is embedded throughout their ecosystem.
Square charges 2.6% + 30¢ per online transaction and 2.9% + 30¢ for in-person chip/contactless. There's no monthly POS fee for basic use, but advanced features and higher transaction volumes can increase costs. Card reader and hardware are low-cost or free.
Best for: Retailers who want advanced features out of the box, multi-purpose use (retail + dining).
Clover (owned by Fiserv) is a hardware-first POS with a large app marketplace. It works in restaurants and retail equally well. The system is more feature-dense than Square but requires more setup.
Clover operates on per-transaction fees (typically 2.7% to 2.9% depending on volume and card type) plus hardware costs. Hardware ranges from $200 to $1,500+ depending on the device. Some merchants bundled into Fiserv processing may negotiate better rates.

Choose ParallelPOS if: You're running multiple locations, manage a team with payroll and scheduling needs, or want a single platform for POS, inventory, and back-office. Request a demo to see how ParallelPOS centralizes your operations.
Choose Square if: You're a solo retailer, just starting out, or want the fastest possible setup with minimal upfront costs. Square's simplicity and mobile-first design suit low-complexity retail operations.
Choose Clover if: You need a versatile system that handles both retail and food service, or you want a highly customizable hardware platform with an app marketplace.
The best POS for your small retail store depends on your growth plans, budget, and operational complexity. If you're scaling beyond one location or juggling payroll and scheduling manually, ParallelPOS eliminates the toolbox approach. If you value simplicity and low barriers to entry, Square remains the fastest path. Clover works well for retailers with advanced customization needs and modest transaction volumes.

It depends on your operation. If you manage one small store with minimal staff, a basic POS like Square works fine. But if you're tracking payroll, scheduling multiple employees, managing inventory across locations, or processing commissions, an all-in-one system like ParallelPOS saves time, reduces errors, and cuts costs from paying for separate tools.
Which POS system has the lowest total cost of ownership?
ParallelPOS has no per-transaction fees, so high-volume retailers see the lowest percentage costs. Square has zero monthly fees but charges per transaction, which adds up fast. Clover charges per-transaction plus hardware. The lowest cost depends on your monthly transaction volume and staff size. Request a pricing comparison for your specific situation.
Can I switch POS systems later if I choose the wrong one?
Yes, but it involves data migration, staff retraining, and downtime. Choosing a system aligned with your growth plans (not just today's needs) prevents costly switches. Most systems can export historical sales data, but employee schedules, customer histories, and loyalty program data may not transfer cleanly.
Is hardware included with these POS systems?
ParallelPOS works on standard iPad, Android, or Windows devices you likely already own. Square requires a cheap card reader ($29-$49) and works on any iPad or phone. Clover requires proprietary hardware ($200-$1,500+). If you already have tablets or phones, ParallelPOS or Square minimize hardware costs.
Which system integrates best with accounting software?
Square and Clover both integrate with QuickBooks and other accounting platforms via plugins. ParallelPOS also supports accounting integrations. Check your specific accounting software's app marketplace to confirm compatibility before choosing a POS system.
