Net 30 and other payment terms explained

Net 30 means the full invoice amount is due 30 days after the invoice date. It is the most common B2B payment term: long enough to give business customers room to process and pay, short enough to keep your cash cycle moving.

Terms set the deadline, but they only matter if you collect to them. A net-30 term where the average customer pays on day 48 is really net 48, and the gap is cash trapped in receivables. Understanding the terms is step one. Enforcing them is where the cash actually lives.

What does net 30 mean?

"Net" refers to the full amount due, with no early-payment discount applied. The "30" is the number of days the customer has to pay. So net 30 is the entire balance, due 30 days out.

The start date matters. Most invoices count from the invoice date, but you can anchor terms to a different event:

• Net 30 from invoice date. The default. The clock starts the day you bill.
• Net 30 from delivery or receipt. The clock starts when goods or services arrive. Common in distribution and manufacturing.
• Net 30 EOM (end of month). All invoices in a month are due 30 days after that month closes, which simplifies a customer's payment runs.

State the start point on the invoice. Ambiguity here is one of the quiet reasons invoices age past due.

Common payment terms explained

Beyond net 30, a handful of terms cover most B2B billing:

• Due on receipt. Payment is expected immediately. Used for new accounts, small jobs, or higher-risk customers.
• Net 15. Due in 15 days. Tighter terms for faster cash or shorter-cycle work.
• Net 45 / Net 60 / Net 90. Longer terms, often demanded by large buyers with leverage. Each extra day is working capital you are financing for the customer.
• 2/10 net 30. A 2% discount for paying within 10 days, full amount otherwise due in 30.
• CIA (cash in advance) / CBD (cash before delivery). Payment up front. Used for first orders or shaky credit.
• 50% upfront, balance on completion. Split terms common in project and services work.

Net 30 vs due on receipt vs 2/10 net 30

These three get compared most often because they sit at different points on the speed-versus-flexibility line.

Due on receipt is fastest for your cash but the least customer-friendly. It signals low trust, so it fits new or high-risk accounts, not your best customers.

Net 30 is the middle ground and the market default. It is generous enough to be competitive without parking cash for long.

2/10 net 30 tries to get the best of both. You offer net 30 but bait early payment with a discount. The math matters: a 2% discount for paying 20 days early is an annualized cost north of 36%, so use it where freed-up cash is worth more than the margin you give up.

How to choose payment terms

Match terms to risk, margin, and competition, not habit:

1. Check the customer's credit. Stronger credit can earn longer terms. New or weak accounts start tighter, on due-on-receipt or net 15.
2. Look at your margins. Thin margins cannot absorb long terms or early-pay discounts. Healthy margins have room.
3. Watch what competitors offer. Terms are part of the deal. Being far off the market norm costs you sales or cash.
4. Protect your own cash cycle. Terms you extend to customers should line up with how fast you need cash to pay your own bills.

For a deeper walkthrough, set terms inside a clear credit policy so they are consistent across the customer base, not negotiated ad hoc.

Enforcing payment terms

Terms are a promise on paper. Enforcement is what turns them into cash. The pattern that erodes terms is simple: an invoice goes out, the due date passes, and nobody follows up until it is weeks overdue. By then the customer has learned the deadline is soft.

The fix is consistent, timely follow-up the moment an invoice ages. Every invoice needs the right nudge at the right time, before and after the due date, with no gaps. Done by hand across a full ledger, that is exactly the work that slips. The terms you put on the invoice only hold if someone is watching every due date.

How Rex enforces your terms

Rex watches every invoice against its terms and acts the moment one ages. It sends the right reminder at the right time, escalates tone as an invoice moves past due, and keeps following up until the balance clears. It does this across the entire ledger at once, so net 30 actually means 30 days instead of quietly drifting to 50.

When a customer disputes a charge or asks for a payment plan, Rex pauses the cadence and routes that case to a person. The team spends its time on judgment calls, not on chasing due dates that should have collected themselves.
