Supplier Payment Terms: What They Mean, How to Negotiate Them, and How They Affect Your Cash Flow
Payment terms with suppliers are not just an administrative detail. They're a working capital lever that directly affects how much cash you need to run your business.
Most businesses accept whatever terms suppliers offer without negotiating. Some don't even know what terms they're on. Both situations leave money on the table.
Understanding the Terminology
Net 30, Net 60, Net 90: Payment is due within 30, 60, or 90 days from the invoice date (or sometimes from delivery date — confirm which with your supplier).
2/10 Net 30: A 2% discount if you pay within 10 days; full amount due by day 30. The "2/10" part is the early payment discount offer.
COD (Cash on Delivery): Payment is due at the time of delivery. Common for new suppliers or customers with poor payment history.
Prepayment / Pro forma: Payment is required before the goods are shipped or produced. Used when the supplier has significant risk (custom orders, new relationships, large orders from unknown buyers).
EOM (End of Month): Payment due at the end of the month following the invoice date. Sometimes combined with a date: "15 EOM" means payment by the 15th of the month following invoice.
Letter of Credit (LC): A bank guarantee that payment will be made when specified conditions are met. Common in international trade, particularly for large import orders.
How Terms Affect Your Cash Flow
The longer your payment terms, the longer you have your suppliers' capital working in your business. This directly affects your working capital cycle.
Consider two scenarios:
Scenario A: Net 15 payment terms with suppliers. Your customers pay on Net 45. Cash flow gap = 45 - 15 = 30 days. You're funding 30 days of operations between paying suppliers and collecting from customers.
Scenario B: Net 45 payment terms with suppliers. Same customer terms. Cash flow gap = 45 - 45 = 0 days. Your suppliers are essentially financing your operations.
For a business with Rs. 50 lakh in monthly revenue, the difference between Scenario A and B is Rs. 50 lakh × (30/30) = Rs. 50 lakh of additional working capital required in Scenario A. That's either cash you need to have on hand, or borrowing cost.
This is why negotiating better supplier terms is worth real money — and why businesses with better terms can often grow faster with less financing.
The Early Payment Discount Calculation
When a supplier offers an early payment discount (e.g., 2/10 Net 30), you need to calculate whether taking the discount is worth it.
The annualized cost of the discount trade-off:
Effective annual rate = (Discount % ÷ (100 - Discount %)) × (365 ÷ (Payment days - Discount days))
For 2/10 Net 30: = (2 ÷ 98) × (365 ÷ 20) = 0.0204 × 18.25 = 37.2% annualized
This means that by paying 20 days early, you're effectively earning 37.2% per year on that cash. If your cost of capital (or your borrowing rate) is less than 37.2% — which it almost certainly is — you should take the discount.
Early payment discounts are almost always worth taking if you have the cash available. The returns are typically much better than any short-term investment.
How to Negotiate Better Terms
Payment terms are negotiable. Not always by a lot, but usually by something. Here's what helps:
Establish a payment track record first. Suppliers extend better terms to customers who have demonstrated they pay reliably. If you're new to a supplier, COD or Net 15 is reasonable. After 3-6 months of on-time payments, you have grounds to request Net 30 or Net 45.
Order volume is leverage. Larger, more predictable orders justify better terms. If you're committing to a regular monthly order of significant size, you have grounds to negotiate.
Ask for extended terms on seasonal or large orders. Even suppliers who normally require Net 30 may be willing to extend to Net 60 for a one-time large order, particularly if the relationship is good.
Offer something in exchange. Willing to commit to a minimum monthly order? Pre-authorize your bank for payment on the due date (automatic payment reduces their collection effort)? Suppliers often value certainty over the maximum possible payment time.
Compare to what competitors are being offered. Market intelligence about standard terms in your product category gives you a baseline for what's negotiable.
Dynamic Discounting: A More Flexible Approach
Dynamic discounting is a newer arrangement where payment timing and discount rate are negotiable on a per-invoice basis. The supplier offers a sliding scale: pay in 10 days for 2% discount, in 20 days for 1.5%, in 30 days for 1%, full amount at 45 days.
This gives you flexibility to optimize based on your current cash position. When you have surplus cash, take the higher discount. When cash is tight, extend to the full term.
Some supply chain financing platforms facilitate this arrangement, particularly for businesses with large supplier bases.
The Accounts Payable Connection
Knowing your payment terms and using them correctly requires your AP process to be tracking invoice dates, due dates, and available early payment windows per invoice.
If your AP process is manual — someone periodically goes through invoices and decides what to pay — you'll miss early payment windows, potentially pay late (damaging relationships), and leave money in low-value short-term positions when it should be working as early payment discounts.
A systematic AP process with clear due date visibility and payment scheduling is the operational foundation for using payment terms strategically.
When to Prioritize Longer Terms vs. Lower Prices
Both are working capital benefits. Sometimes you can negotiate one or the other, not both.
Prefer lower price if: Your cash position is strong, your alternative investment opportunities are limited, or the discount is significant.
Prefer longer terms if: You're cash-constrained, you're growing fast and need working capital, or you have better uses for the cash over the payment window.
This is a judgment call that should be made deliberately, not by default.
