Quick Verdict
Square charges 2.6% + $0.10 in-person and 2.9% + $0.30 online. Stripe charges 2.7% + $0.05 in-person and 2.9% + $0.30 online. For physical retail under $80,000 monthly, Square is usually cheaper because hardware is free and tap-to-pay is built in. For online-only or developer-driven setups, Stripe wins on API depth, subscriptions, and global currency support.
In person, the crossover ticket is exactly $50: Stripe’s lower fixed fee wins below it, Square’s lower percentage wins above it. Square funds next business day for free; Stripe funds in 2 business days, or instantly for 1.5% of the transfer. Above $80,000 monthly, neither flat rate is the cheapest answer: an interchange-plus processor typically saves 0.30 to 0.60 percent.
Choose Square if you have a physical store and need an all-in-one POS system with free hardware.
Choose Stripe if you're online-first and have technical resources for customization.

“For a typical, low-risk business, your effective rate should be around 3 to 4%.”
| Transaction Type | Square | Stripe | Winner |
|---|---|---|---|
| In-Person (Card Present) | 2.6% + $0.10 | 2.7% + $0.05 | Square* |
| Online/Ecommerce | 2.9% + $0.30 | 2.9% + $0.30 | Tie |
| Keyed-In/Manual | 3.5% + $0.15 | 3.4% + $0.30 | Depends |

Real-World Cost Examples
Coffee Shop
$30K/month, $8 average transaction, 90% in-person
Square: $1,239/month | Stripe: $1,097/month
Stripe saves $142/mo BUT Square offers free POS + free hardware = better overall value
SaaS Company
$100K/month, $200 average transaction, 100% online
Square: $3,050/month | Stripe: $3,050/month
Same price, but Stripe's subscription features are FAR superior for SaaS
Above $80K a month: when neither flat rate wins
Both published rates bake in roughly 0.40 to 0.60 percent of markup over interchange, depending on card mix. Around $80K to $100K in monthly card volume that markup starts costing more than an interchange-plus account. At $250K monthly with a typical retail card mix, an interchange-plus processor with a 0.40 percent markup lands 0.30 to 0.60 percent below either flat rate, roughly $12,000 to $18,000 a year on $3M of annual volume. Stripe offers custom interchange-plus pricing through its sales team above that range; the published 2.9% + $0.30 is the self-serve rate.
| Processor | In-Person | Online | Monthly Fee |
|---|---|---|---|
| Square | 2.6% + $0.10 | 2.9% + $0.30 | $0 |
| Stripe | 2.7% + $0.05 | 2.9% + $0.30 | $0 |
| Helcim (interchange-plus) | Interchange + 0.40% + $0.08 | Interchange + 0.50% + $0.25 | $0 |

Frequently Asked Questions
Which is cheaper, Square or Stripe?
For in-person: Square is slightly cheaper (2.6% + $0.10 vs 2.7% + $0.05). For online: identical (2.9% + $0.30). For ACH: Stripe crushes (0.8% capped at $5 vs 3.3% + $0.30). Overall difference is minimal except for ACH payments.
Which is better for restaurants?
Square wins for restaurants. Square for Restaurants offers table management, course firing, menu modifiers, kitchen display system, tableside ordering, split checks, and tip pooling. Stripe would require building or buying third-party restaurant POS.
Which is better for SaaS/subscription businesses?
Stripe wins hands down. Stripe Billing offers usage-based pricing, metered billing, tiered pricing, per-seat pricing, smart dunning, revenue recognition, and customer portal. Square only offers basic recurring billing.
Do I need a developer for Stripe?
Not necessarily. You don't need a developer if using Stripe with platforms like Shopify/WooCommerce, Stripe Checkout hosted pages, or simple payment links. Developers are helpful for custom checkout design and required for building marketplaces or complex automation.
Can I accept international payments with Square?
Very limited. Square only operates in 8 countries with no currency conversion or local payment methods. Stripe supports 46 countries, 135+ currencies, and local payment methods - making it the clear choice for international businesses.
Can I switch from Square to Stripe (or vice versa)?
Yes, and it's straightforward with no cancellation fees from either processor. Timeline is typically 1-3 weeks including account setup, integration, customer data migration, and testing.
When does it make sense to leave Stripe or Square for interchange-plus?
Around $80K to $100K in monthly card volume, the markup baked into a 2.6 to 2.9 percent flat rate starts costing more than a monthly subscription or a small interchange-plus markup. At $250K monthly volume with an average retail card mix, an interchange-plus processor with a 0.40 percent markup typically lands 0.30 to 0.60 percent below either flat rate. On $3M annual volume that is roughly $12,000 to $18,000 saved per year. The exception is if you have heavy seasonality or unstable volume, where unpredictable monthly fees can hurt more than the percentage savings help.
Does Square ever charge a monthly fee?
Not on the free plan. Square POS, Square Dashboard, and basic invoicing are free, and you only pay per transaction. Square does charge monthly subscriptions for vertical-specific software: Square for Restaurants Plus is $69 per location per month, Square for Retail Plus is $89 per location per month, Square Appointments Plus is $29 per location per month. Square Online is free with paid plans starting at $29 per month for custom domain and removed Square branding. Hardware is sold separately. PCI compliance, statement fees, and account closure fees are not charged on the standard plan.
Why is Stripe's published rate higher than what large enterprises pay?
The 2.9 percent plus 30 cents number is Stripe's standard plan, designed for self-serve signups under $80K monthly volume. Stripe offers custom interchange-plus pricing through its sales team for higher-volume merchants, where the markup is typically negotiated as a small percentage and per-transaction fee on top of true interchange. The published rate has to cover Stripe's full cost (interchange, network fees, processing margin, fraud risk, and software) for any account that signs up without a conversation, so it is intentionally above what a $1M+ monthly volume merchant would actually pay after negotiation.
Can Square hold my money?
Yes. Square's Seller Agreement allows account holds, rolling reserves, and termination at Square's discretion, particularly for merchants in higher-risk categories or those whose volume patterns trigger automated risk filters. Common triggers include a sudden volume spike, high chargeback ratio, or a merchant category code (firearms, supplements, CBD, ticket resale, certain coaching) that Square treats as elevated risk. Funds are typically held for 30 to 90 days. The defensive move for any business in those verticals is to set up a parallel interchange-plus merchant account on day one, so a Square hold does not freeze your operations.
Final Verdict
Square = Physical Business - Best all-in-one solution for any business with a physical location. Free to start, easy to use, everything included.
Stripe = Online Business - Best payment infrastructure for online businesses, especially with technical resources and growth plans.
The Simple Truth: Both are excellent. The right choice depends entirely on your business model. Choose Square for physical/hybrid businesses. Choose Stripe for online/tech businesses.
