Paying by purchase order
Billing · For everyone · Updated Oct 20, 2026 · 1 min read
You can join or renew without a card. Choose Invoice me on the payment step and enter your purchase order number.
What happens next
- ICAA issues an invoice with your PO number on it. It is due in 30 days.
- Your membership is pending until the invoice is paid. Benefits open when payment is recorded.
- Pay by check or ACH and quote the invoice number. ICAA Finance records the payment and your membership becomes active the same day.
Finding the invoice
Open Billing in your workspace. Open invoices are listed first; choose an invoice number to see and print it.
Common questions
- Can I change from PO to card? Yes. Open the invoice in Billing and choose Pay now.
- The invoice is overdue. Pay it or open a ticket from Support and tell us when payment is expected. A pending membership stays pending; nothing is cancelled automatically.
- We need a W-9 or vendor form. Open a Billing ticket and attach your form. Billing tickets always reach ICAA Finance.
