How the calculation works

Payment terms are usually counted in calendar days starting from the date on the invoice. An invoice dated 1 March on Net 30 terms is therefore due on 31 March. Weekends and public holidays count as normal days unless your agreement says otherwise.

Payment terms you will often see

• Due on receipt: payment falls due on the same day the invoice is dated.
• Net 7, Net 10, Net 15: the due date is 7, 10 or 15 days after the date on the invoice.
• Net 30: payment is due 30 days after the invoice date, a term used by many businesses.
• Net 45, Net 60, Net 90: payment is due 45, 60 or 90 days after the invoice date.
• EOM (end of month): the due date is the last calendar day of the month of the invoice.
• Net 30 EOM: the 30 days start counting from the end of the invoice month.

EOM wording is not used the same way by everyone, so it is worth checking your agreement.

If the due date is a Saturday or Sunday

Some companies move a Saturday or Sunday due date to the next working day. Switch on the weekend option and a Saturday or Sunday due date moves to Monday.

What invoice payment terms mean

Payment terms describe when an invoice should be paid and under what conditions. They normally appear on the invoice, typically close to the invoice date and the amount due. Clear terms tell the customer exactly how long they have to pay. They also give both sides a shared reference point if a payment arrives late. Terms are normally agreed before the work starts or the goods are delivered.

How Net terms work

Net terms combine the word Net with a number of days, for example Net 15 or Net 30. That number is the count of days after the invoice date by which the full amount must be paid. Net means the full invoice amount, without any discount for early payment. Short terms such as Net 7 or Net 10 give the customer only a few days to pay. Longer terms such as Net 60 or Net 90 give the customer more time but mean you wait longer for the money. For any Net term, you get the due date by counting that number of days from the invoice date.

Terms based on the end of the month

Some payment terms are linked to the end of the month instead of the invoice date. With plain EOM terms, the invoice is due on the last day of the month in which it is dated. For instance, an invoice dated April 12 on EOM terms is due on April 30. With Net 30 EOM, you first go to the end of the invoice month and then add 30 days. An invoice dated 12 April on Net 30 EOM terms would be due on 30 May. These terms group all invoices from one month into a single payment cycle, which some customers prefer.

Discounts for paying early

A seller may offer a small discount when an invoice is paid well ahead of the due date. The term 2/10 Net 30 gives the customer 2% off if they pay within 10 days. If the customer does not take the discount, the full amount is due 30 days after the invoice date. For an invoice of 1,000 on 2/10 Net 30, payment within 10 days would be 980. The discount window is counted from the invoice date in the same way as the Net period. A discount may bring payment in sooner, but it lowers the amount you collect.

Counting the days

Normally the invoice date counts as day zero. The day after the invoice date is day one of the count. This is why an invoice dated June 1 on Net 30 is due on July 1. Because months differ in length, Net 30 does not always land on the same date of the next month. In a non-leap year, an invoice dated January 31 on Net 30 is due on March 2. Using a calculator avoids errors with short months and leap years.

Weekends, holidays and business days

Ordinary Net terms are counted in calendar days, weekends and holidays included. Some contracts use business days instead, which skip weekends and holidays. A term in business days ends later than the same number of calendar days. This calculator uses calendar days and can move a weekend due date to Monday. It does not leave out public holidays, as they vary between countries and regions.

Picking the right payment terms

Shorter terms mean you are paid sooner and wait less for your money. Some customers, larger companies in particular, may request longer terms. It is easier to agree terms before starting the work than at the moment you send the invoice. Using the same terms for similar customers keeps your records simple. Whichever terms you pick, show them on every invoice. Writing the actual due date next to the terms removes any doubt.

What to show on the invoice

An invoice usually includes its date, a unique invoice number and the total due. Next to these, show the payment terms, such as Net 30, and the due date they give. If there is an early payment discount, state the discount and the last day it applies. Include the payment methods you accept, so the customer knows how to pay. A complete and clear invoice helps the customer pay on time.

Common questions

Does Net 30 include weekends?

Usually yes: Net 30 counts calendar days, including weekends, unless the agreement specifies business days.

Which day is day one?

The day after the invoice date is day one, so the invoice date itself is not counted.

Is the due date the last day to pay?

Yes, the due date is the last day on which payment is on time under the agreed terms.

Is it worth printing the due date on the invoice?

Writing the date as well as the terms removes any doubt about when payment is expected.
