At a glance

  • Your payroll invoice shows what your company needs to pay or fund.
  • It can include employee pay, employer-side costs, benefits, reimbursements, service fees, and adjustments.
  • Invoice totals can differ from employee payslip amounts because the two documents answer different questions.
01

What a payroll invoice is

A PIO payroll invoice is a company billing document. It helps your finance team review the payroll-related amount due for a billing period and pay it through the correct funding or payment method.

The invoice is not an employee payslip. A payslip explains one employee's gross-to-net pay. The invoice explains the amount your company owes for payroll and related services.

02

What can appear on the invoice

Depending on your service setup, an invoice can include salary or wages, approved bonuses, commissions, allowances, reimbursed expenses, employer-side taxes or statutory contributions, benefits, local employment costs, platform or service fees, and billing adjustments.

Some items are employee-level payroll amounts. Others are company-level charges. PIO keeps them together on the customer invoice so your finance team can fund the full employer cost in one place.

03

How to review an invoice

Start with the billing period, currency, due date, and total amount. Then review the employee-level breakdown and any company-level fees or adjustments.

If the invoice includes more than one country or region, line names may vary by local payroll practice. For example, a statutory item in Germany may be named differently from an item in Singapore or China, Hong Kong.

If an amount looks different from the employee payslip, compare the invoice category first. Employer costs, service fees, benefits, and certain billing adjustments may not appear on the employee's payslip.

Before paying

  1. 01Confirm the billing period and currency.
  2. 02Review employee-level payroll amounts and company-level charges separately.
  3. 03Check whether any credits, adjustments, or reimbursements are included.
  4. 04Make sure your payment method and due date are correct.

Common questions

Why does the invoice total not match one employee's net pay?
Net pay is the amount paid to an employee after deductions. A customer invoice can include more than net pay, such as employer taxes, benefits, service fees, reimbursements, and adjustments.
Does an invoice replace the employee payslip?
No. The invoice is for the company payer. The payslip is for the employee and explains that employee's pay calculation.
Who should review invoice questions?
Finance teams usually review totals, due dates, and payment status. Payroll or HR teams usually review employee-level payroll components.
