Blanket invoice template
Blanket invoice template is used to bill against a blanket purchase order (BPO) or master agreement. Instead of one PO per order, the buyer has one BPO for repeated purchases; you issue an invoice for each delivery or period, referencing the BPO number and agreed prices. Common in procurement, recurring supplies, and contract-based purchasing.

An invoice should include your business or name, the customer’s details, the date and invoice number, and a line-by-line breakdown of what was provided. Including payment terms—such as due on receipt, Net 15, or Net 30—helps you get paid on time and keeps records clear for taxes.

Frequently Asked Questions
