Quick answer: Square is the accessible generalist in supported markets; Shopify POS fits retailers already centered on Shopify commerce; Lightspeed offers deeper retail or restaurant operations; Toast is restaurant-specific in supported markets; Clover combines merchant hardware and an app ecosystem through providers. Price software, hardware, processing, and contract together.
What are you actually buying?
A point-of-sale system combines checkout software, payment acceptance, receipts, catalog, taxes, staff access, and often inventory or customer records at the selling location. It is not merely a card terminal and it is not the same as an ecommerce platform. Hardware lifecycle, processing contract, offline behavior, and industry workflow shape the real cost.
This guide is for an owner or operator with a measurable workflow problem who is comparing a subscription, managed service, or business system—not collecting tool names. Write down the current process, team size, transaction volume, required countries, and desired outcome before taking a demo. If the problem cannot be described in one sentence, a larger platform will not resolve the ambiguity.
How this category was evaluated
We compared registers and mobile hardware, software subscriptions, processing fees, offline mode, returns, taxes, tips, inventory, variants, staff and permissions, reporting, ecommerce sync, multi-location support, industry features, data export, and regional availability.
The shortlist began with the current commercial search results and was checked against official product and pricing material on 2026-09-13. We do not claim unperformed hands-on testing and do not manufacture numerical scores. Prices vary by country, tax, currency, contract, annual billing, and usage, so the guide records the published model and asks buyers to confirm the final quote.
Side-by-side comparison
| Product or service | Best for | Published pricing model | Main limitation |
|---|---|---|---|
| Square POS | Small general retailers and service sellers wanting fast entry | Published free and paid software with processing and hardware costs | Supported countries and Square ecosystem determine fit |
| Shopify POS | Omnichannel retailers already using Shopify | Published software, hardware, and processing pricing by market | Best economics depend on Shopify Payments and plan choices |
| Lightspeed | Retailers or restaurants needing deeper industry operations | Published starting plans with quote-led components | Subscription, payments, hardware, and onboarding can be substantial |
| Toast | Restaurants needing purpose-built front and back-of-house workflows | Published packages and custom quotes with processing/hardware terms | Restaurant and market focus plus contract economics reduce general fit |
| Clover | Merchants wanting provider-supplied hardware and an app marketplace | Hardware, software, and processing vary by reseller and plan | Pricing and support can vary by acquiring partner |
Where each option fits—and where it does not
Square POS: Small general retailers and service sellers wanting fast entry
Why it made the shortlist: Integrated payments, catalog, basic inventory, staff tools, reports, and broad hardware. It is best considered for small general retailers and service sellers wanting fast entry, with published free and paid software with processing and hardware costs as the published or stated pricing model. Confirm the regional plan, billing period, included usage, and required add-ons at the point of purchase.
The trade-off: Supported countries and Square ecosystem determine fit. Avoid outside supported markets or for deep manufacturing inventory. Before committing, run the real workflow, export a representative data set, test a non-admin role, and trigger a failure or support case. A familiar brand or longer feature list is not evidence that the operating fit is better.
Shopify POS: Omnichannel retailers already using Shopify
Why it made the shortlist: Strong online-store connection, unified catalog/customer data, and retail workflows. It is best considered for omnichannel retailers already using shopify, with published software, hardware, and processing pricing by market as the published or stated pricing model. Confirm the regional plan, billing period, included usage, and required add-ons at the point of purchase.
The trade-off: Best economics depend on Shopify Payments and plan choices. Avoid if Shopify is not the ecommerce system or local payments are unsupported. Before committing, run the real workflow, export a representative data set, test a non-admin role, and trigger a failure or support case. A familiar brand or longer feature list is not evidence that the operating fit is better.
Lightspeed: Retailers or restaurants needing deeper industry operations
Why it made the shortlist: Advanced inventory, purchasing, multi-location, reporting, and vertical editions. It is best considered for retailers or restaurants needing deeper industry operations, with published starting plans with quote-led components as the published or stated pricing model. Confirm the regional plan, billing period, included usage, and required add-ons at the point of purchase.
The trade-off: Subscription, payments, hardware, and onboarding can be substantial. Avoid for a simple occasional market stall. Before committing, run the real workflow, export a representative data set, test a non-admin role, and trigger a failure or support case. A familiar brand or longer feature list is not evidence that the operating fit is better.
Toast: Restaurants needing purpose-built front and back-of-house workflows
Why it made the shortlist: Restaurant ordering, menus, kitchen, labor, guest, and payment workflows. It is best considered for restaurants needing purpose-built front and back-of-house workflows, with published packages and custom quotes with processing/hardware terms as the published or stated pricing model. Confirm the regional plan, billing period, included usage, and required add-ons at the point of purchase.
The trade-off: Restaurant and market focus plus contract economics reduce general fit. Avoid for non-restaurant retail or unsupported countries. Before committing, run the real workflow, export a representative data set, test a non-admin role, and trigger a failure or support case. A familiar brand or longer feature list is not evidence that the operating fit is better.
Clover: Merchants wanting provider-supplied hardware and an app marketplace
Why it made the shortlist: Flexible devices, payments, apps, inventory, staff, and industry configurations. It is best considered for merchants wanting provider-supplied hardware and an app marketplace, with hardware, software, and processing vary by reseller and plan as the published or stated pricing model. Confirm the regional plan, billing period, included usage, and required add-ons at the point of purchase.
The trade-off: Pricing and support can vary by acquiring partner. Avoid until the exact processor contract, ownership, and exit terms are clear. Before committing, run the real workflow, export a representative data set, test a non-admin role, and trigger a failure or support case. A familiar brand or longer feature list is not evidence that the operating fit is better.
Calculate total cost, not the subscription alone
Normalize every quote into first-year and steady-state cost. Include setup, migration, consulting, training, minimum seats, usage, transaction fees, hardware, integrations, support, storage, and premium controls. Then include the internal owner who must maintain rules, data quality, permissions, and reports. A free entry plan can be excellent, but it is not free if it creates manual reconciliation, traps data, or forces a replacement six months later.
Give every vendor the same scenario: identical users, volumes, entities, countries, and integrations. Ask the seller to label what is included, what is an add-on, and what happens beyond each limit. Do not anchor a long-term decision to an introductory discount or annualized price until renewal, cancellation, and data-return terms are understood.
Test migration, controls, and failure before purchase
Build a trial or proof of concept with non-sensitive data that represents real work rather than a polished vendor demo. Test roles, approval, correction, export, integration, duplicate handling, and an error path. Request the applicable service commitment and retention/deletion terms, then identify who can access company data and who approves configuration changes.
Design the exit at the beginning: export format, attachments, historical events, identity fields, and retrieval window. If a coherent business record cannot be reconstructed outside the platform, switching cost is higher than it appears. For financial, employment, payment, or legal workflows, validate jurisdiction-specific requirements with qualified local advisers instead of treating a global feature label as universal compliance.
Practical buying checklist
- What record or outcome must this system own?
- Who owns configuration, data quality, and monthly review?
- Which countries, entities, currencies, and channels must actually work?
- Which plan contains the required capabilities at next year’s scale?
- Which usage, hardware, implementation, or processing costs sit outside the base price?
- How will data move into the authoritative accounting and operating systems?
- Can least privilege, separation of duties, and an audit export be demonstrated?
- How will data be recovered and work continue if the service fails or is replaced?
- Which real workflow will the team test during the trial or proof of concept?
- What test result will produce a purchase or rejection decision?
Final decision framework
Square is the accessible generalist in supported markets; Shopify POS fits retailers already centered on Shopify commerce; Lightspeed offers deeper retail or restaurant operations; Toast is restaurant-specific in supported markets; Clover combines merchant hardware and an app ecosystem through providers. Price software, hardware, processing, and contract together.
Reduce the market to two or three credible options, run one scripted scenario, and obtain a written quote. Choose the system that performs the essential job clearly and that the team can operate, audit, and leave—not the vendor displaying the most logos.
