Square Payroll: Best overall Our rating: 4.00 out of 5 Image: Square Square Payroll helps small businesses manage their online payroll operations. It runs payroll automatically and handles tax filing across federal, state, and local tax jurisdictions, including end-of-year tax reporting. It supports various employee payment options, such as manual paychecks, direct deposits, and instant payouts via the Square Cash application. This is unlike other providers, such as QuickBooks Payroll, which requires you to upgrade to its higher plans to get same-day payments. In addition, Square Payroll is compatible and integrates with client payment processing and accounting software, such as Square POS and QuickBooks Online. The automatic data syncs between Square and its partner programs make tip tracking and bookkeeping easy. Pricing Square Payroll offers two pricing plans: Full-service payroll: $35 per month plus $6 per employee per month. Contractor-only payroll: $6 per employee per month. With an overall score of 4 out of 5 in my evaluation, Square Payroll is cheaper than Gusto and OnPay (both with monthly fees of $40 + $6 per employee). However, it has limited HR tools. Square Payroll also charges an annual fee of $3 per form if you want them to mail paper copies of payroll tax forms—although digital versions of tax documents are free. Square Payroll pros and cons Pros Cons Easy integration with Square products Limited HR tools Intuitive mobile app with payroll features Lacks 24/7 support and HR advisory services Straightforward system and account setup Why I chose Square Payroll If you have a retail or service-based business, Square’s extensive product suite makes it a good option for managing payments, point-of-sale transactions, and payroll for one employee. Its different products sync easily, and you can transfer funds from your Square balance to the Square Cash app to pay yourself instantly or send funds to your bank account for two- or four-day direct deposit payouts. I also like its online seller community or forum, where you can connect with other small business owners and Square users. This is helpful if you need advice on boosting sales or have questions about using Square Payroll’s features. Square Payroll has an automatic pay run option that you can easily switch on and off.

Justworks: Best for compliance support Our rating: 3.91 out of 5 Image: Justworks As a professional employer organization (PEO) service provider, Justworks handles the intricacies of pay processing to give you more time to run your business. However, apart from its PEO service, it has a payroll-only option that includes automatic wage and deduction calculations, tax filing assistance, and payroll compliance. This is great for one-employee businesses looking for a reliable payroll tool because most PEOs require at least two employees if you want to sign up for its services. Even with its payroll-only option, you get dedicated phone support and integration options with accounting tools like QuickBooks Online for easy pay data transfers and accurate bookkeeping. It also provides real-time alerts to help keep you on top of federal and state compliance requirements. This leaves you with more time running your business instead of constantly checking labor laws and federal regulations for updates. Pricing Justworks Payroll costs $50 per month plus $8 per employee per month. This option doesn’t include health or retirement plans like most of the software on my list. However, if want to get medical, dental, and vision insurance, its health insurance add-on for the payroll-only plan costs $8 per employee per month. If you decide to expand your business globally and need help hiring and paying international workers, you can get its employer of record (EOR) services for $599 per employee per month. For its PEO services, Justworks offers two plans: Basic: $59 per employee per month. Plus: $109 per employee per month. With a 3.69 out of 5 score, Justworks Payroll may be pricier than the others on my list, but it offers more than processing payroll for 1 employee. You get the benefit of its compliance expertise as a PEO, so you’re assured that pay processes always meet federal and state regulations. You
