Both Wave and Square are ideal for startups and small businesses with low-volume sales. Both also offer free invoicing tools and a payment processing service locked into each provider’s system. However, Square as a payment processor is compatible with more business types while Wave is limited to merchants that only need invoicing and remote payment functionalities.
This glaring difference allowed Square payments to stand out, while Wave did not make it in our evaluation of the best online payment processors. That said, Wave offers better invoicing and recurring billing tools that are completely free, with features that Square and other top merchant processors would charge extra for.

Winner: Wave
Wave’s advantage over Square (and most top merchant processors) is that it offers a completely free invoicing and recurring billing service. All the customization options you would look for—adding custom fields including tipping methods, creating estimates and multiple subscription plans, saving templates and invoices for recurring billing, and converting estimates into invoices are all included.
Square on the other hand, will charge you $20 monthly to get invoice customization and use recurring billing features. Along with free integrated bookkeeping, solo professionals and contractors can maximize their revenue with only credit card processing fees to worry about.

When to Use Square
If you are a retailer or run a food-based business that requires invoicing (such as caterers) and /or shipping, then Square is the better option. While Wave does have a product management feature, it lacks customization tools retailers would need. Meanwhile, Square’s invoicing custom fields include options like shipping, and they integrate with Square’s more robust inventory feature. In addition to more payment methods, you can also create custom contracts for your subscription plans with Square.
Square’s invoicing dashboard is more robust and offers additional functions such as creating a contract, but will cost merchants $20/month to use. (Source: Square)

Winner: Square
Square is clearly the more cost-effective solution for businesses that work with employees, whether full time or contractual. It has scheduling, as well as tips and commission tracking, which Wave does not have. Also unlike Wave, Square does not charge a monthly fee if you only have contractual hires. Square also offers more payout method options and provides merchants with a free mobile app to manage payroll tasks on the go.
Additional Square Payroll features:
- Tip and commission tracking
- Employee access to Benefits
- Employee Pay on demand via Cash App
- Employee shift scheduling w/ Square team management.
- Team messaging via app
- Worker’s compensation insurance

Every free Square account also comes with basic team management tools that have time tracking and payroll reporting functionalities. (Source: Square) 
Square provides employers and employees with a free mobile app where they can communicate and workers can track their attendance, pay stubs, and schedules. (Source: Square)
When to Use Wave
WIth its own accounting integration, Wave stands out in terms of tax reporting and compliance. However, since these features are available at a higher plan ($40), it may not be encouraging for small merchants, considering Square also provides automated tax filing (Wave can do this only for 14 states) and payroll expert resources at no extra cost. This brings us back to our recommendation of Wave for solo professionals, gig workers, and contractors. Merchants can still access all of Wave’s payroll features while paying only $20/month—considerably less than Square’s monthly fee.
Additional Wave payroll features:
- One-click payout
- Automatic payroll journal entries
- Workers’ compensation insurance
- Customizable payroll expense reporting
- Priority customer support
Wave provides you with a comprehensive payroll dashboard that displays pending tasks, payout records, and more. (Source: Wave)

Wave vs Square Reporting
When to Use Wave
Wave’s reporting features are largely tied to its accounting service. This means that invoice records automatically update account receivables, payroll payouts create instant adjustments to expense and accruals, and product records reflect both services rendered and company supplies purchased. If you are a solo professional, having Wave’s accounting integration removes the heavy, repetitive compliance tasks, leaving you more time to attend to clients.
When to Use Square
With Square, reporting is more segmented according to business type. So, while you can create multiple business profiles, Square does not have Wave’s capability to create an aggregated report of your businesses. What Square can do, though, is provide you with omnichannel business reporting. Any adjustments to sales and inventory are automatically synced in one report regardless if you have more than one location, or if you sell on multiple platforms (in-store, online store, social media, mobile, etc.).
Square’s sales reporting features are basic compared to other top merchant processors. In retail, for example, you only get sales data plus cost of goods sold, profit margin, and vendor sales if you upgrade to a Square Retail paid plan. On the other hand, you can use Square to generate smaller reports tracking cash, tips and commissions, and low-stock alerts.
Wave vs Square Integrations
Winner: Square
Square offers a better range of integration options starting with its own suite of add on products. You will also find a diverse range of third-party integrations such as self-order kiosks and delivery management apps that will allow Square to scale with the business. Aside from its proprietary add-ons, Square also has an app marketplace for its software partners, giving it a clear lead against Wave both by numbers and a variety of integrations.
Square integration options:
- Square POS software

- Square Invoicing
- Square Online
- Square Payroll
- Square Team Management
- Square Marketing
- Square Business Checking
- Square Loyalty
- Square Cash App
- Afterpay (BNPL)

Wave integration options:
- Wave Payroll
- Wave Invoicing
- Wave Payments
- Wave Money

Both Wave and Square are payment facilitators so merchants only need to sign up for an account but will not be subjected to an approval process. Once you have provided all the necessary information, you are free to start sending out invoices and accepting payments. However, the common downside for all merchants with payment facilitators is that they are more prone to account holds and frozen funds. Learn more about merchant accounts.
That said, payment facilitators are the most ideal for startups and small businesses because of simple pricing and often zero monthly fees. So in order to decide between Square vs Wave, we focus on getting the most out of features such as more control over chargeback and fraud management.

First hand experience is important in order to build a concrete comparison between two small business-friendly solutions like Wave and Square.
