Net 30 vs Net 15 vs Due on Receipt: Which Payment Terms Should You Use?

The short answer

If you’re a small business or freelancer, Net 30 is probably costing you cash flow. Net 14 or Net 15 is the sweet spot for most service businesses today, and Due on Receipt works for product-based or recurring relationships. Net 30 should be reserved for large enterprise clients who genuinely need that long for AP cycles.

The longer answer depends on your industry, your clients, and how much cash you need on hand. Let’s break it down.

What payment terms actually mean

"Payment terms" tells your client how many days they have to pay an invoice after you send it. The most common options:

The two outliers worth knowing:

• EOM (End of Month): Payment due at the end of the month the invoice was issued. Common in retail and wholesale.
• COD (Cash on Delivery): Payment required before goods are released. Used for first-time clients or high-risk transactions.

Why Net 30 became the default (and why it shouldn’t be)

Net 30 became standard in the 1900s when businesses physically mailed paper checks. The 30-day window covered: invoice mailed, received, processed, check cut, mailed back, deposited, cleared. That made sense in 1950.

Today, with ACH transfers, online invoice links, and same-day banking, the 30-day window is mostly a habit — one that disproportionately hurts small businesses. The math is brutal:

• If your average invoice is $5,000 and you send 4 per month on Net 30, you have $20,000+ tied up in receivables at any given moment
• That same volume on Net 14 ties up roughly half — about $10,000
• The difference is real cash you could be using for payroll, ad spend, or growth

You also need to factor in late payments on top of your stated terms. According to Atradius, 48% of B2B invoices are paid late, with the average late payment running 14 days past due. Net 30 in practice often means Net 44.

Which payment terms should you choose?

Match the term to the situation:

The case for shorter payment terms

Beyond the obvious cash flow benefit, shorter terms have second-order effects most business owners don’t think about:

1. Faster feedback on bad clients. If a client is going to pay late, you’ll know in 14 days instead of 30. You can stop work, escalate, or fire them before sinking more time in.
2. Smaller follow-up workload. Half the receivables window means roughly half the overdue invoices to chase at any given time.
3. Better client behavior. Clients on Net 14 actually pay closer to the due date than Net 30 clients, on average. The shorter window creates urgency.
4. Compounding. Money received 16 days earlier can pay your own bills, fund growth, or earn interest. Over a year, that’s real money.

How to actually set (or change) your payment terms

For new clients

Set your terms in your contract before work starts. Don’t spring Net 14 on a client who assumed Net 30 — that’s a fight you don’t need. Your contract should specify:

• Payment terms (e.g., "Net 14 from invoice date")
• Late fee policy (typically 1.5% per month past due)
• Accepted payment methods
• What happens if payment is missed

For existing clients on Net 30

Don’t change terms mid-relationship without warning — that breaks trust. Instead, use one of these approaches:

1. Tie it to a renewal or new project. "Starting with our next engagement, we’re moving to Net 14 across the board to match industry standard."
2. Offer an early payment discount. 2/10 Net 30 gives the client a 2% discount if they pay within 10 days. Many enterprise AP departments will actually take the discount because it nets them ~36% APR equivalent.
3. Add a late fee. If clients keep paying you on day 35 of Net 30, a documented late fee gives you leverage. See our late payment fees guide for the legal limits and contract language.

Early payment discounts: are they worth it?

The classic "2/10 Net 30" structure means: pay full price within 30 days, OR get 2% off if you pay within 10 days. From the client’s perspective, taking that 2% discount is equivalent to earning ~36% annualized return — better than any short-term investment.

From your perspective, you’re giving up 2% of revenue to get paid 20 days earlier. Whether that’s worth it depends on:

• Your cost of capital. If you’re running on a credit line at 12% APR, getting cash 20 days earlier is worth ~0.66% of the invoice. Giving up 2% is a loss.
• Your alternative use of cash. If 20 extra days of cash means you can take on a new project, hire a freelancer, or run more ads, the 2% can be more than worth it.
• The client’s reliability. If a client is chronically late, the discount could prevent the invoice from going to 60+ days overdue.

For most small businesses, a flat shorter term (Net 14) beats Net 30 with an early payment discount. Less complexity, same result.

What to do when clients pay late anyway

Even with Net 14, plenty of clients will pay late. Your follow-up game is what closes the gap between stated terms and actual cash in hand.

The pattern that works:

• Day 5 past due: friendly reminder — most are just busy
• Day 14 past due: firmer follow-up with deadline
• Day 30 past due: final notice, reference late fee

The bottom line

Default to Net 14 for most small business work. Use Due on Receipt for repeat or small invoices. Reserve Net 30 for large clients who actually need it. Add a late fee policy regardless.

Pair shorter terms with a clear invoice and consistent follow-up, and you’ll have your cash in hand 2-3 weeks earlier on average. Over a year, that’s the difference between a stressed business and a healthy one.
