Net 30

Net 30 is a credit payment term meaning the full invoice amount is due within 30 calendar days from the invoice date. It allows business customers time to review goods and process payments without paying upfront.

What it means

In business-to-business commerce, sellers rarely expect buyers to pay immediately upon delivery. Instead, they issue an invoice with specific payment terms.

Net 30 is one of the most common standards. The word net indicates that the total balance is due with no deductions, and the number 30 represents the payment window in days.

For non-finance managers, understanding Net 30 is vital because it directly impacts cash flow. When you make a sale on Net 30 terms, you do not receive cash on the day you deliver your product or service.

You must wait up to a month to get paid, even though you likely incurred expenses for materials and labour immediately. This delay creates a gap between doing the work and collecting the money.

If a company takes on too many Net 30 clients without managing its working capital, it can run out of cash despite being profitable on paper. Conversely, offering Net 30 terms can help you win clients who require delayed payment schedules to match their own cash flow cycles.

In practice

Real-world examples.

1

Example

A graphic design agency completes a website rebrand for a client on the first of the month and issues a bill for 2,000 pounds. Under Net 30 terms, the client has until the 30th of that month to send the payment.

2

Example

A small bakery supplies wholesale bread to local cafes, agreeing to Net 30 terms. The cafes receive weekly deliveries in January and must settle their accumulated January bills by the end of February.

3

Example

An office furniture supplier delivers desks to a tech start-up. The invoice of 5,000 pounds is dated 10 May, meaning the start-up must transfer the funds by 9 June to avoid late fees.

Think of it

Net 30 is like borrowing a library book. You take the item home immediately, but you have 30 days before you actually have to return it to the shelf.

Formula

Calculation

Payment Due Date = Invoice Date + 30 Days. Example: If an invoice is issued on 12 April (Day 0), the payment due date is calculated as 12 April + 30 days = 12 May.

Case study

Seen in the real world.

Oakwood Landscaping secured a large commercial contract to maintain grounds for a business park, billing 4,000 pounds per month on Net 30 terms. Oakwood completed the January maintenance and sent an invoice on 31 January. However, because of the client's internal accounts payable schedule, the funds did not arrive until 2 March. Meanwhile, Oakwood still had to pay its gardeners weekly wages and purchase fuel and fertilizer throughout February. To bridge this gap, the owner learned to track cash flow closely, ensuring the business held enough reserve cash to cover forty days of operating expenses before taking on more Net 30 corporate clients.

Watch out

Common mistakes.

  • Confusing Net 30 with 30 days from the end of the month, which is actually Net 30 EOM.
  • Failing to run credit checks on new clients before offering them Net 30 terms.
  • Ignoring the impact on cash flow and spending money that has been invoiced but not yet collected.

Questions

People also ask.

Does Net 30 mean 30 business days or calendar days?

It means calendar days, including weekends and public holidays.

Can I offer a discount for early payment?

Yes, sellers often pair Net terms with an early payment incentive, such as 2/10 Net 30, offering a two percent discount if paid within ten days.

What happens if a customer does not pay within 30 days?

The invoice is overdue. Sellers typically follow up with reminders, and many charge late fees or interest as stated in their terms.
