EOM Payment Terms: Net 30 EOM Meaning With Examples

EOM stands for "end of month" (Merriam-Webster). On an invoice it ties the due date to the end of the month the invoice is dated in, instead of to the invoice date itself. That gives every invoice of a month the same due date, which suits clients who pay their suppliers once a month. Below: what each EOM term means, the due dates worked out, how EOM compares with net 30 and the wording to put on your invoice.

What EOM means on an invoice

• Due EOM: payment is due on the last day of the month the invoice is dated in.
• Net 30 EOM, also written 30 days EOM: payment is due 30 days after the end of that month. Net 15 EOM, net 45 EOM and net 60 EOM work the same way with other numbers.

The days are calendar days, counted from the last day of the invoice's month.

EOM due dates, worked out

For an invoice dated November 10, 2026:

Terms	Due date	Weekday
Due EOM	November 30, 2026	Monday
Net 15 EOM	December 15, 2026	Tuesday
Net 30 EOM	December 30, 2026	Wednesday
Net 45 EOM	January 14, 2027	Thursday
Net 60 EOM	January 29, 2027	Friday
Net 30, for comparison	December 10, 2026	Thursday

An invoice dated November 28, 2026 on net 30 EOM is also due December 30: the date in the month does not matter, only the month.

EOM vs net 30

Net 30 counts from the invoice date, so each invoice has its own due date. Net 30 EOM counts from the end of the month, so:

• Your clients get longer. On net 30 EOM an invoice waits between 30 and 60 days, depending on when in the month it is dated: one dated on the last day waits 30 days, one dated on the 1st waits the whole month first.
• Everything is due on one day. All of November's invoices are due on December 30, which fits a client who pays suppliers in a monthly run.
• A day late can cost a month. An invoice dated November 30, 2026 on net 30 EOM is due December 30; dated December 1, it is due January 30, 2027. On EOM terms, invoice the day the work is done.

If you are the one choosing, net terms or due on receipt get you paid sooner. EOM is usually the client's request, and it is worth pricing in, like any longer term.

Short months and "30th after EOM"

Net 30 EOM counts days. February 2027 has 28 days, so an invoice dated January 31, 2027 on net 30 EOM is due March 2, 2027, not on a day in February.

Some invoices say "net 30th after EOM" or "the 30th of the following month". That is a calendar date, not a count of days: it is a prox term ("prox" means next month), and February has no 30th. Our guide to net 10th prox explains those terms and what happens in short months. Wording varies between businesses, so whatever you agree, print the date.

How to write EOM terms on an invoice

Spell out the terms once, then the actual date:

Payment terms: net 30 EOM (30 days after the end of the invoice month). Due date: December 30, 2026.

In a quote or contract:

Invoices are payable 30 days after the end of the month in which they are dated.

In Excel or Google Sheets, with the invoice date in A2: =EOMONTH(A2,0) gives due EOM and =EOMONTH(A2,0)+30 gives net 30 EOM. The due date calculator set to net 30 EOM does it for any date and lists the other common terms beside it; change the days for net 15 EOM or net 60 EOM.

How Clodou helps

Clodou is an AI back office you run by chat. Its default payment terms count days from the invoice date (net 30, net 15…), and there is no EOM setting. For a client on EOM terms, give the due date in your message ("invoice Harbour Foods for the November deliveries, $2,400, due December 30") and it prints on the invoice PDF. If a price is missing, Clodou asks instead of guessing.

Once the date passes, the invoice shows up when you ask "Who owes me money?" and in your daily brief, and Clodou prepares payment reminders as cards you approve before anything is emailed.

Key takeaways

• EOM means end of month. "Due EOM" is the last day of the invoice's month.
• Net 30 EOM (30 days EOM) is 30 days after that day: a November invoice is due December 30.
• On net 30 EOM an invoice can wait up to 60 days, and an invoice dated a day into the next month waits a month more: invoice the day the work is done, or ask for net 15 EOM.
• "The 30th of the following month" is a prox term, not EOM, and short months change it.
• Print the actual due date next to the terms so nobody has to count.
