A credit note refunds any over-billed amount from the prior month's reconciliation, applied per line item to the original prior-month subscription invoice.
A credit note is issued when the actual amount paid out on your behalf was lower than what we billed on the subscription. We refund the difference back to you, applied to the original prior-month subscription invoice.
Credit notes work differently from debit invoices:
Credit notes are applied per employee, per line item — the credit lands on the specific line on the original prior-month invoice (under that employee), matching the chart of accounts.
Debit invoices are aggregated by charge type across all employees in a single new invoice.
For example, if we billed $2,000 in employer pension contributions for an employee in March but the actual amount paid was $1,800, you'd see a $200 credit applied to the pension contribution line under that employee on your March subscription invoice.
