LET’S DO THIS

We’re here when you’re ready

Try OnPay out yourself to see how easy payroll and HR can be. To get started, just share a few basic details about your business. Our team of pros will set everything up and import your employees’ information for you.

Decide what payroll features you need

Every small business has different needs, so make sure you know exactly what you’ll be getting. Most notably, take a closer look to understand everything Paychex Flex and OnPay do to simplify paying and managing your team. And if you need to go above and beyond payroll, make sure you understand how much HR, benefits, and integrations with accounting software will all cost so there are no surprises later.

  • What full-service payroll features should I expect?

    Not only do you want a platform to be able to pay your team quickly and easily, but you also want to be sure that your payroll provider will get your local, state, and federal taxes filed and paid accurately, so you can rest knowing things are done right. If you have employees in multiple states or locations, consider whether your provider will charge an additional fee.

     

    With OnPay’s accuracy guarantee, you can be sure your taxes are being filed and paid correctly, no matter how many states your workers are located in — at no additional cost. Note that Paychex Flex charges extra fees for multi-state payroll.

  • What integrations are available?

    Great payroll providers will also have integrations with time-tracking and accounting software. In a perfect world, you want your time and attendance system to talk to your payroll system and in turn, have those expenses flow right to your accounting platform.

     

    OnPay integrates with top accounting and time-tracking systems at no extra cost. Our flexible integrations with QuickBooks and Xero give you the ability to customize data and view your finances in the way that makes the most sense for your business.

  • Do I have special payroll requirements for being in a certain industry?

    Businesses in different industries (and of different sizes) sometimes have different payroll tax and withholding requirements. From filing Form 943 filing for ag businesses to accurately processing special pay types like bonuses, tips, or commissions, take a close look to ensure all your needs will be met.

     

    OnPay serves businesses from all industries including farms and ranches, construction, restaurants, doctors, nonprofits, start-ups, and more. So, we can handle any specialized payroll requirements for your business, at no additional cost.

  • Do I need HR and compliance?

    The best payroll providers will not only help you with payroll, but also with HR and compliance through features like employee self-service, PTO tracking and approval, e-signable documents and storage, organization charts, and more. And, they should also offer integrated benefits and workers’ comp plans (without extra fees for the features and integrations you’ll need).

     

    OnPay offers a full suite of HR tools to help you take care of your team ⁠— at no extra cost. And with integrated pay-as-you-go workers’ comp and benefits plans in multiple states, we’ll make sure you’re staying compliant while keeping your employees happy.

  • Is account setup and customer support offered?

    When getting set up with a payroll provider, it can feel like a long and complex process to get all your data migrated. That’s why your payroll provider should offer to migrate all your prior wage and employee data for free, including help getting all your integrations set up. This level of service makes for a much more seamless transition. You also want to know that your payroll provider will be there to help beyond just setup, in case you have questions or need help with anything in the future.

     

    OnPay will set up your account and migrate all your prior wage and employee data for free, so setup is simple. Note that Paychex Flex charges an additional setup fee. And, with OnPay, you can get help from a payroll expert whenever you need it. Email support begins at 7 AM EST on weekdays, while phone and chat are available from 9 AM to 8 PM EST.
