Choosing a POS system is one of the biggest operational decisions a retail business makes. You need something that handles sales, inventory, staff management, and customer data—without slowing you down or draining your budget. Three popular options are ParallelPOS, Toast, and Square. This guide breaks down how they compare so you can pick the right fit for your store.
All three systems handle basic transactions, but with different strengths. Square is the simplest—it works on any device and is quick to set up. Toast is enterprise-focused, built primarily for restaurants but adaptable to retail. ParallelPOS is purpose-built for retail and service businesses, with multi-location support from day one.
For checkout speed and offline functionality, ParallelPOS and Square both perform well. Toast requires stronger internet reliability, which can be a problem if your connection drops.
Inventory is where the differences become clear. Square's inventory tools are basic—useful for small single-store operations but limited for tracking stock across locations or managing reorder points effectively.
Toast offers inventory management but charges extra for advanced features, and it's not as intuitive for retail workflows as it is for food service.
ParallelPOS includes full inventory management in the core platform—multi-location inventory sync, low-stock alerts, SKU tracking, and supplier integration. No extra fees for core inventory features.
If you run or plan to run multiple locations, this matters. Square requires separate accounts per location, making centralized reporting and team management tedious. Toast is designed for chains but with a premium price tag and complex setup.
ParallelPOS is built for multi-location from the ground up. You manage all stores from one dashboard, consolidate reporting, and sync inventory across locations in real time.
Square does not offer built-in team scheduling or payroll. You'll need to integrate third-party apps, which adds cost and complexity.
Toast has some scheduling features but charges separately for payroll and the tools feel bolted-on rather than integrated.
ParallelPOS includes team scheduling, payroll processing, and sales commissions in one platform. Schedule staff, process payroll, and track who sold what—no separate apps needed. This integration saves time and reduces errors. See how other retail owners manage teams with ParallelPOS.
All three collect customer data, but Square and Toast treat it as secondary. ParallelPOS has a built-in CRM designed to help you track customer purchase history, preferences, and lifetime value—useful for loyalty programs and targeted marketing.
Square is cheapest upfront—you only need a reader ($49–$299). Toast and ParallelPOS typically require dedicated hardware (terminals, printers, displays) starting around $500–$2,000 depending on setup.

As you grow, percentage-based systems (Square, Toast) become more expensive. ParallelPOS scales predictably.
Square wins on simplicity and learning curve. It's intuitive for a first-time user. But that simplicity comes with limited features.
Toast has more power but a steeper learning curve. Support is good but often requires navigating a restaurant-first interface.
ParallelPOS is designed for retail and service owners. The interface matches how you think about your business—sales by product, inventory by location, payroll by pay period. Onboarding is straightforward, and support focuses on small business needs.
If you're a small retailer with one location and minimal staff, Square is fast and affordable. If you're a chain restaurant, Toast makes sense. But if you're a retail or service business looking to grow, ParallelPOS combines POS, inventory, scheduling, payroll, and CRM in a single platform built for your business model.
The right POS system should support how you work today and scale as you grow tomorrow. Request a demo to see ParallelPOS in action and compare it side-by-side with your current options.

Square requires separate accounts per location, which makes centralized reporting, inventory management, and team oversight difficult. You'd need workarounds or third-party tools to unify data across stores. ParallelPOS and Toast both handle multi-location natively, though ParallelPOS is simpler for retail.
Does Toast work for retail, or just restaurants?
Toast is primarily designed for restaurants and food service. While it can be adapted for retail, many retail-specific workflows (SKU management, merchandise returns, loyalty programs) feel awkward. Its pricing and interface are also optimized for high-frequency transactions typical of food service, not retail.
What are ParallelPOS's monthly costs?
ParallelPOS uses a fixed monthly software fee model (no percentage per transaction). Exact pricing depends on your store count, feature set, and user count. Payment processing is separate and competitive. Visit the pricing page or request a demo for accurate quotes based on your store's needs.
Which system is easiest to learn?
Square is the easiest to learn due to its minimal feature set and mobile-first design. ParallelPOS is straightforward for retail owners because its interface follows retail workflows. Toast has the steepest learning curve because it's enterprise software with many toggles and configurations.
Do any of these include payroll?
Only ParallelPOS includes payroll processing as a core platform feature. Square and Toast both require third-party integrations (Guidepoint, ADP, Stripe Connect, etc.), which adds cost and complexity.
