There is at the moment no straight forward way for tracking payroll. But there is a workaround.
Let your accountants enter payroll costs
We recommend keeping your accounting software as the source of truth for payroll. However, you can still track payroll costs in Planyard as well as part of costs.
One option is to add a new line-item to the project budget. It could be called, for example, "General costs" or "Payroll costs".
You would then have to agree with accounting how to enter those costs. It's quite common that these are entered once per month or once per quarter by the accountant. It's a matter of agreement (depending on the project length as well).
Note that you can also Consolidated Invoices (if the feature is not turned on for you, ask your support) for splitting costs between projects.
