Payment Terms (Net 30, 2/10 Net 30): The Cheapest Financing Most SMBs Will Ever Access

Payment terms define when a buyer must pay a supplier after receiving goods — and they are the cheapest form of financing most SMBs will ever access.

A supplier offering Net 30 is extending a zero-interest, 30-day loan on every invoice. That free float directly reduces your cash conversion cycle by increasing DPO. Yet most small operators pay invoices the day they arrive, voluntarily surrendering weeks of free credit because nobody tracks when payment is actually due.

Quick answers

What are the most common payment terms? COD (Cash on Delivery), Net 15, Net 30, Net 60, 2/10 Net 30 (2% discount if paid within 10 days, full amount due in 30), EOM (End of Month), and CIA (Cash in Advance). Net 30 is the most common default for established supplier relationships.

What does 2/10 Net 30 mean? The supplier offers a 2% discount if you pay within 10 days of the invoice date. If you do not take the discount, the full amount is due in 30 days. The implicit cost of skipping the discount is 37.2% annualized — almost always worth taking if you have the cash or a credit line below that rate.

How do payment terms affect cash flow? Longer terms give you more time to sell inventory and collect revenue before the supplier invoice is due. Net 60 instead of Net 30 means 30 extra days of float on every order — effectively a free, revolving credit facility sized to your purchasing volume.

Can I negotiate better payment terms? Yes. Suppliers extend better terms to buyers with reliable payment history, consistent volume, and low credit risk. Start by paying on time for 3-6 months, then ask. Offer volume commitments or longer contracts in exchange for extended terms.

Common terms explained

The formula: annualized cost of skipping an early-payment discount

Annualized Cost = (Discount % / (100% − Discount %)) × (365 / (Full Days − Discount Days))

For 2/10 Net 30:

Annualized Cost = (2 / 98) × (365 / 20)
               = 0.0204 × 18.25
               = 37.2%

You are paying 2.04% for 20 extra days of float. Annualized, that is a 37.2% interest rate. If your cost of capital — whether a business credit card, line of credit, or opportunity cost on cash — is below 37%, take the discount. For most SMBs, it is.

The further apart the discount window and the due date, the cheaper it is to skip. 2/10 Net 60 — 2% for 50 extra days — is 14.9% annualized, closer to a typical line of credit rate. Still usually worth taking, but not the automatic decision that 2/10 Net 30 is.

Worked example

A business orders $15,000/month from a supplier offering 2/10 Net 30.

Option A: Always take the discount (pay on day 10)

• Monthly discount: $15,000 × 2% = $300
• Annual savings: $300 × 12 = $3,600
• Cash required: $15,000 available on day 10 of each cycle

Option B: Always pay on day 30 (skip the discount)

• No discount captured
• Cash available 20 days longer per cycle
• Value of that float at 8% cost of capital: $15,000 × (20/365) × 8% = $65.75/month = $789/year

Net comparison: Taking the discount saves $3,600/year. Skipping it saves $789/year in float value. The discount wins by $2,811 annually — and that gap widens with order volume.

The math scales linearly: at $30K/month, the gap is $5,622/year.

Why most operators get this wrong

1. They do not track due dates systematically. Without a system that knows when each invoice is due, operators either pay early (losing free float) or pay late (damaging the supplier relationship and losing access to better terms). Both outcomes are worse than paying on the optimal day.

2. They skip early-payment discounts without calculating the cost. Skipping 2/10 Net 30 feels like "keeping cash longer." It is actually paying 37% annualized interest for 20 days of float. Most operators would never take a 37% loan, but they make the equivalent decision every invoice cycle.

3. They never negotiate. Payment terms are not fixed properties of the universe. They are the output of a supplier's credit decision about your business. Reliable payment history, volume commitments, and timing your ask to the supplier's slow season all improve the outcome. Operators who never ask stay on COD or Net 15 indefinitely.

4. They negotiate terms and MOQ separately. Minimum order quantities and payment terms are the two main levers in a supplier negotiation. Trading a higher MOQ commitment for Net 60 instead of Net 30 can be worth more in working capital than the discount per unit.

How LineNow handles it

LineNow tracks payment terms at the supplier level and surfaces them at every decision point in the procurement loop:

Terms visibility on every PO. When a purchase order is created, the supplier's payment terms are displayed alongside the order total — so the buyer sees the cash commitment timeline, not just the dollar amount.

Early-payment discount tracking. For suppliers offering discount terms, LineNow flags invoices approaching the discount window so operators do not accidentally let a 2% discount expire. The annualized cost of skipping is calculated automatically.

DPO impact on cash forecasting. Payment terms feed directly into procurement capital forecasting — showing how much cash will be due to suppliers in each of the next 10 weeks, broken down by supplier and PO. Operators see the cash flow impact of their terms portfolio before placing the next order.

Negotiation context. Supplier order history — on-time payment rate, total volume, order frequency — is available in one view, giving operators the data to support a terms negotiation. Start a 90-day free trial at linenow.co.
