Before you commit to implementing new payroll software, you should make sure it fits with your workflow and needs. Open-source payroll software typically doesn’t have all the bells and whistles you get with the best payroll software, but you should still consider these important features.
If you’re used to licensed software, you may be surprised to find that most open-source payroll software has very limited customer support. These platforms often rely on community forums to offer support. So, if you’re worried about the technical challenges of implementing a new payroll solution, you may want to look for software with dedicated customer support.
While some open-source payroll software offers mobile and online access, many tools don’t. In fact, quite a few open-source platforms require installation on your own server. That might work for businesses with office-based employees, but if you have a hybrid or remote workforce, you’ll need to figure out remote server access ― or just choose software that provides online access.
Integrations with accounting, time tracking and other software can keep your payroll more accurate and save you lots of time. If you already rely on specific software, you should check to see if your potential payroll solutions will sync with your existing apps. Or, if you have the know-how, open-source software makes it easier to build your own integrations.
Most payroll software comes with some level of automation, even if it’s just calculating taxes for you. More advanced automation can automatically distribute payslips, file tax documents and sync with outside software. If you want to spend less time on payroll, look for software with more extensive automation tools.
Payroll rules and regulations vary widely by jurisdiction, so it’s helpful to have payroll software that can adapt to your (or your employees’) location. That can include allowing for different currencies, but the best software also localizes tax calculations.
The best open-source payroll software for your business should give you a more affordable, flexible experience than licensed competitors. It ought to include essential payroll functions, like tax calculations and payslip creation, along with helpful features for time and employee management.
That said, different businesses will have different needs from their payroll software. The best payroll software for accountants, for instance, will need seamless integrations with popular accounting software and robust customer support. But payroll software for a small retail store may care more about timesheets and online access. Make sure you think through what matters to your business so you end up with open-source payroll software that actually solves your problems, instead of creating more.
