To say an invoice is due immediately, the most direct and standard term to use is "Due upon receipt". This phrase indicates that payment is required as soon as the client receives the invoice, typically within the same day or by the next business day.
“Payment is due immediately upon receipt of this invoice.” “Please process payment within one business day to avoid delays.” Provide clear payment links and instructions, for example: “Complete payment by using our online payment portal.”
Remember: an invoice requiring immediate payment should not come as a surprise. Clients should understand that payment is due upon receipt when your contract is completed.
