Only if you have employees, and not necessarily even then. QuickBooks payroll is a separate subscription that bolts onto your accounting and handles RTI submissions, payslips and pension uploads, with the advantage that the wage journals post straight into your books without anyone rekeying them. That integration is the real benefit. Against it: standalone payroll software is often cheaper, and if we run your payroll for you it makes no difference to you which system we use, since you get the same payslips either way. For a single director taking a simple monthly salary, the add-on is usually more than you need. For a business with a dozen staff, weekly variations and auto-enrolment to manage, the integration starts paying for itself.
