A debit invoice is a separate invoice we issue when the actual amount paid out on your behalf was higher than what we billed on the subscription. It captures the under-billed amounts from the prior month's reconciliation.
In practice, debit invoices are almost always driven by ad-hoc and variance items billed in arrears:
Approved items — overtime, bonuses, commissions, financial assistance (approved by your team's direct manager via Outstaffer's approval workflow)
Auto-applied items — public holiday loading, penalty rates, night differentials (applied per local labour law)
The debit invoice is a single invoice per customer per month, grouped by charge type across all your employees. So if three employees each had a small variance on the same line item, those amounts appear as one combined line on the debit invoice. The per-employee breakdown is in the Payroll Reconciliation Report — the debit invoice itself notes "Refer to your payroll reconciliation report for [Month]" to direct you there.
