Worked example
An invoice dated 31 January 2026 on Net 30 terms is due on 2 March 2026. On 30 days EOM terms it would be due 30 days after 31 January, on 2 March as well; dated 10 February, Net 30 gives 12 March but 30 days EOM gives 30 March.
When to follow up
Send a friendly reminder on the due date and a firmer one a week later. The client follow-up email templates include invoice reminders you can copy.

What does EOM mean on an invoice?

Do weekends count?
Yes. Payment terms use calendar days unless your contract says business days.
