can I use the payroll core without useing the quickbook subscription?

You can only sync it with QBO or use it as a stand alone app. If you are using Xero, you can use a 3rd party payroll app like Gusto.

I agree with SIAB, Juanitarhoy. Let me further elaborate on this topic.

Yes, you can use QuickBooks Payroll Core without QuickBooks Online. However, it requires a separate subscription. QuickBooks Payroll Core includes payroll features, but it does not offer bookkeeping functionalities.

On the other hand, as SIAB mentioned, QuickBooks Payroll integrates exclusively with QuickBooks’ accounting software. Thus, integrating with other accounting apps, such as Xero, is not possible. However, you can transfer payroll data from QuickBooks Payroll to Xero by exporting payroll reports and manually entering or uploading them into Xero.

Also, consider exploring QuickBooks Payroll to enhance your payroll processing. This way, you'll have access to advanced features that simplify handling unique setups, like recording payroll history and managing tax payments.
