Compare small business POS software and systems by card processing fees, monthly cost, hardware, inventory needs, and business fit.
Best POS Software Quick Picks
These picks are scenario-based, not universal rankings. Compare the total cost of software, hardware, processing, and contract terms before choosing.
| POS | Best for | Monthly software cost | In-person processing | Key caution |
|---|---|---|---|---|
Square Best first POS for simple setup | New sellers, pop-ups, simple counters | $0 monthly POS software | 2.6% + $0.15 card-present | Flat-rate processing can become expensive as volume grows. |
Shopify POS Best for online + in-person retail | Shopify stores and omnichannel retail | Plans from $39/month; POS Pro add-on listed at $89/month per location | Basic in-person rates start at 2.6% + $0.10 | Ecommerce plan, POS add-ons, and processing rates all affect total cost. |
Lightspeed Retail Best for inventory-heavy retailers | Boutiques, specialty retail, multi-location shops | Retail plans listed from $89/month | Lightspeed Payments rates start at 2.6% + $0.10 | Verify payment rates, add-ons, and whether the software depth is worth the monthly cost. |
Clover Best for bundled hardware packages | Businesses wanting hardware and software in one package | Varies by package and business type | Varies by package and business type | Verify cancellation, payoff, hardware, and processing terms before signing. |
Helcim Best for fee-focused merchants | Simple workflows and processing-cost transparency | $0 monthly POS software with a Helcim account | Interchange-plus; published in-person margin starts at interchange + 0.40% + $0.08 | POS tools are simpler than full retail inventory platforms. |
Best POS Software by Use Case
A small business POS search can mean simple checkout software, a full retail system, a bundled hardware package, or a lower-fee payment setup. Start with the use case before comparing rates.
| Use case | Start by comparing | Why it fits |
|---|---|---|
| Simple first POS software | Square | Low setup friction, public flat-rate pricing, and no monthly POS software fee for simple sellers. |
| Online plus in-person retail | Shopify POS | Best fit when ecommerce orders, store inventory, customer data, and in-person checkout need to stay connected. |
| Inventory-heavy retail POS | Lightspeed Retail | Stronger fit for boutiques and specialty retailers that need purchase orders, variants, stock transfers, and reporting. |
| Bundled hardware POS system | Clover | Worth quoting when the business wants hardware, software, and payment acceptance packaged together. |
| Fee-focused payment and POS setup | Helcim | Useful when processing-cost transparency matters more than deep retail inventory tooling. |
Check POS Fees Against Your Sales Volume
POS software cost is only one part of the decision. Processing fees often become the larger ongoing cost, especially as monthly card sales grow.
How to Choose a Small Business POS
Before comparing feature lists, decide how your business sells. A counter-service shop that only takes in-person payments has a different cost profile from a retailer splitting sales between a store and an online shop.
Monthly card volume matters because processing fees compound. At low volume, a no-monthly-fee POS can be hard to beat on simplicity. As volume grows, the difference between a flat-rate plan and a lower-markup pricing model can become large enough to quote alternatives.
Inventory complexity matters too. A business with a short menu does not need the same tooling as a boutique with thousands of SKUs, stock transfers, purchase orders, and multiple locations. For more background, read the credit card processing fees guide. If you are comparing flat-rate pricing against interchange-plus pricing, use the Helcim vs Square fee comparison.

Detailed Recommendations
Best first POS for simple setup
Square
Who it fits: New businesses, pop-ups, farmers market vendors, simple retail counters, and service businesses that want a low-overhead way to accept cards.
Pricing: Square POS software is listed with a $0 monthly fee, no contracts, no setup fees, and no hidden fees. Square's POS pricing page lists card-present processing at 2.6% + $0.15, card-not-present at 2.9% + $0.30, and keyed-in at 3.5% + $0.15.
Hardware and features: Square lists hardware examples such as Square Stand at $149, Square Terminal at $299, Square Kiosk at $149, and Square Register at $799.
What to watch: Square's flat-rate pricing is easy to understand, but the blended rate can become worth rechecking as monthly volume grows. Compare your effective rate before assuming the free software plan is still the lowest total cost.
Next step: Helcim vs Square comparison.
Best for online + in-person retail
Shopify POS
Who it fits: Retailers already using Shopify, or businesses that want online store orders, in-person checkout, customer data, and inventory connected in one system.
Pricing: Shopify's POS pricing page lists Basic from $39/month, Grow from $105/month, Advanced from $399/month, and Plus from $2,300/month on a three-year term. POS Pro is listed as an add-on at $89/month per location.
Hardware and features: Shopify POS Pro adds features such as staff roles and permissions, customer profiles, inventory management, retail reports, and omnichannel selling.
What to watch: Costs can stack when you combine ecommerce plan cost, POS Pro, hardware, and payment processing. Model both online and in-person sales before choosing a plan.
Best for inventory-heavy retailers
Lightspeed Retail
Who it fits: Boutiques, specialty retailers, multi-location stores, and businesses where inventory control, purchasing, stock transfers, and reporting are central to operations.
Pricing: Lightspeed Retail pricing lists Basic at $89/month, Core at $149/month, and Plus at $289/month, each with one register included. Lightspeed notes pricing can vary and additional service fees may apply depending on the business and industry.
Hardware and features: Lightspeed Retail features include inventory management, multi-location inventory, stock transfers, location comparison reporting, shared customer database, integrations, reporting, and staff management.
What to watch: Lightspeed can be more software than a simple seller needs. Verify quote-specific payment rates, add-ons, register costs, and whether inventory tools justify the subscription.
Best for bundled hardware packages
Clover
Who it fits: Businesses that want a packaged hardware and software setup selected around a business type, such as retail, quick-service, full-service, or professional services.
Pricing: Clover says merchants can expect a monthly software fee plus processing rates per transaction, and fees vary by business type. Pay-monthly subscriptions can include hardware and software in one monthly price, with processing fees priced separately.
Hardware and features: Clover is strongest when the business wants hardware, software, and payment acceptance packaged together rather than assembled from separate vendors.
What to watch: Clover's pricing page says subscriptions are non-cancelable and ineligible for refunds, though subscriptions can be paid off and certain buyout or upgrade situations may apply. Verify the full contract before signing.
Best for fee-focused merchants
Helcim
Who it fits: Service businesses, simple counters, and merchants that care more about payment processing transparency than advanced retail inventory features.
Pricing: Helcim says its POS software is included with a free Helcim account. Helcim uses interchange-plus pricing, and its published in-person margin starts at interchange + 0.40% + $0.08 for $0-$50K in monthly credit card volume.
Hardware and features: Helcim support lists the Helcim Card Reader as a one-time purchase of $99 USD and the Helcim Smart Terminal as $329 USD. US merchants can also use Tap to Pay on iPhone without additional hardware.
What to watch: Helcim is not the same kind of full retail inventory suite as Lightspeed or Shopify POS. Treat it as a fee-focused payment/POS option for simpler workflows.
Next step: Helcim vs Square comparison.

Best Retail POS Systems for Small Business
Retail POS searches can mean several different workflows. A simple counter shop may only need checkout, sales tax, receipts, and basic items. An inventory-heavy retailer may need purchase orders, stock transfers, variants, vendor records, and multi-location reporting.
For retail stores, compare Shopify POS when online and in-person inventory need to stay connected, Lightspeed Retail when inventory depth is central, Square when the store needs a simple low-overhead start, and Clover when a bundled hardware package is more important than software flexibility.

Fee Scenario Examples
These simplified examples show why the best POS system depends on sales channel, monthly volume, average ticket, and software needs.
Low-volume seller on a simple flat-rate POS
- Monthly card sales
- $10,000
- Average ticket
- $40
- Transactions
- 250
- Rate
- 2.6% + $0.15
- Monthly processing
- $260 + $37.50 = $297.50
- Effective rate
- 2.98%
A no-monthly-fee POS can make sense when volume is still modest and the business values simplicity.
Online + in-person seller
- Monthly card sales
- $30,000 split evenly
- Average ticket
- $60
- Transactions
- About 250 in-person and 250 online
- In-person cost
- $390 + $25 = $415
- Online cost
- $435 + $75 = $510
- Total processing
- $925
- Effective rate
- 3.08%
Online sales can raise blended processing cost, so ecommerce and POS integration should be compared with fees.
Inventory-heavy retailer with monthly software cost
- Monthly card sales
- $50,000
- POS software
- $89/month example
- Processing
- Use quote-specific rates
- Main question
- Do inventory tools prevent more cost than the monthly fee?
The software fee can be reasonable if inventory, reporting, stock transfers, and purchasing tools save enough time or prevent stock mistakes.
POS Cost Checklist
- Processing fees: Compare card-present, online, invoice, keyed, and card-on-file rates.
- Monthly software: Verify the plan tier, location count, register count, and add-ons you need.
- Hardware: Check whether hardware is purchased, financed, leased, or bundled into a subscription.
- Add-ons: Inventory, loyalty, gift cards, employee tools, reports, and ecommerce features can change the monthly total.
- Contract terms: Look for annual commitments, cancellation language, non-cancelable subscriptions, and hardware payoff rules.
- Processor flexibility: Ask whether you must use built-in payments or whether outside processors are allowed.
Methodology and Assumptions
The pricing data in this guide comes from public provider pages as of May 13, 2026. Processing examples use simplified assumptions for education; actual costs vary by card mix, transaction method, business category, plan tier, hardware, and contract terms.
CardFeeCheck is not a payment processor and does not negotiate rates. We compare public pricing, fee models, and business-fit scenarios so small business owners can ask better questions before requesting quotes.

FAQ
What is the best POS system for a small business?
There is no universal best POS system. Square fits simple new sellers, Shopify POS fits omnichannel retail, Lightspeed fits inventory-heavy stores, Clover fits bundled hardware packages, and Helcim fits merchants focused on payment processing transparency.
How much does a small business POS system cost?
POS cost usually includes monthly software, card processing fees, hardware, and add-ons. The systems in this guide range from $0 monthly POS software to retail plans listed at $89/month or more, before hardware and processing costs.
Should I choose a free POS system?
A free POS can be a good starting point for a simple or low-volume business. Recheck the math as volume grows because flat-rate processing can cost more than lower-markup models at higher card volume.
Which POS has the lowest processing fees?
The lowest processing cost depends on volume, average ticket, card mix, and channel. Interchange-plus options such as Helcim are worth comparing for fee transparency, while flat-rate systems can be simpler at lower volume.
Is Square good enough for a small business?
Square can be enough for many simple businesses that want quick setup and no monthly POS software fee. Re-evaluate if you need deeper inventory tools, multi-location workflows, or lower-markup processing at higher volume.
Is Shopify POS worth it for a retail store?
Shopify POS is most compelling when a retailer sells both online and in person and wants inventory, orders, and customer data in one system. Compare ecommerce plan cost, POS Pro, hardware, and processing together.
Can I use my own payment processor with a POS system?
Some POS systems allow outside processors, while others require or strongly favor built-in payments. Check whether using another processor changes monthly fees, features, support, or contract terms.
What should I check before signing a POS contract?
Verify monthly software cost, card-present and card-not-present rates, hardware purchase or lease terms, add-ons, contract length, cancellation terms, processor flexibility, and whether any subscription is non-cancelable.
Final Recommendation
Do not start by asking which POS is best in the abstract. Start by asking what your business needs and what the full cost will be after software, hardware, processing, and contract terms.
Square is a practical first POS for simple sellers. Shopify POS is strongest when online and in-person retail need to work together. Lightspeed Retail is built for inventory depth. Clover is worth quoting for bundled hardware packages. Helcim is worth comparing when processing transparency is the priority.
Before switching, model the impact with the credit card fee calculator and benchmark your current statement with the effective rate calculator.
