Invoice due date questions

What does Net 30 mean?

Net 30 means payment is due 30 calendar days after the invoice date, unless your contract explicitly says business days.

Are Net terms calendar or business days?

They normally refer to calendar days. If a deadline falls on a weekend, many businesses use the next working day; confirm this in your agreement.

What does EOM mean on an invoice?

EOM means end of month: payment is due on the final calendar day of the month in which the invoice was issued.

When should I send an invoice reminder?

A friendly reminder three to seven days before the deadline and another on the due date can prevent many late payments.
