Invoice date
The invoice date is the date an invoice is formally issued to the customer. It often starts the payment-term calculation and helps place the transaction in the seller's records, but it is not always the same as the supply, service or payment date. Local tax and invoicing rules may define when an invoice must be issued.
Why this matters when you invoice
The invoice date anchors the document in time. It helps calculate the due date, organize records and distinguish the billing date from delivery, service and payment dates.
Where it appears on an invoice
Show it prominently near the invoice number and due date. Where another date matters—such as service, delivery or payment—label that date separately.
Invoice date example
Work is completed on 31 August 2026 and the invoice is issued on 2 September 2026. With Net 14 terms calculated from the invoice date, payment is due on 16 September 2026.
Common mistakes
- Using the payment date as the invoice date.

Frequently asked questions
Is the invoice date always the service date?
No. They may match, but the service or supply date can be different and may need to appear separately.
Does the due date always start from the invoice date?
It commonly does, but the agreement may use another starting event. State the resulting calendar due date clearly.
