Negotiating payment terms in B2B isn't about begging for a few extra days: it's about arbitrating a balance of power over your cash flow. A supplier who imposes net 30 on you while you collect at 60 is financing your customer at your expense. A buyer who demands 90 days turns your margin into a bank overdraft. The subject is technical, but it plays out at the table, in words. Here is the method I apply and teach, illustrated by a real case.
The real stakes: the payment term is a hidden price
Thirty extra days on an annual contract worth 500,000 euros ties up roughly 41,000 euros permanently. At today's cost of credit, that adds up to several thousand euros a year. Time isn't free: it's a financial line item that too many company directors concede without ever putting a figure on it. Before any discussion, work out what each 15-day tranche is worth. That figure becomes your compass and stops you caving in to the wear and tear of the conversation.
Prepare your fallback position before you sit down
The first mistake is walking into the meeting without knowing what you'll do if it fails. Your BATNA, another supplier who'll accept 45 days, a negotiated factoring facility, an early-payment discount, determines your real room for firmness. Without a fallback, you're not negotiating, you're accepting. Also list your objective criteria: statutory limits (the 60-day cap in France), sector practice, an impeccable payment history. A term backed by an external standard is far harder to challenge than a personal preference.
The experience: how I turned 30 days into 60
An industrial SME I was advising depended on a components supplier who insisted on payment at 30 days, while the SME itself was settled at 75 by its own clients. Every order deepened the working-capital gap. The director wanted to "ask for a gesture". I advised him against the soft request.
We opened with a deliberate anchor: "To align our flows, we're starting from settlement at 75 days, in line with our own collections." The salesperson opposite flinched. Rather than justify himself, the director applied silence, five seconds, not a word. It was the other side that filled the void: "75 is impossible for us, the finance department will never go along with it."
At that point, instead of digging in, he used the mirror effect: "The finance department will never go along with it?" The salesperson then let slip the key piece of information: the real sticking point wasn't the deadline, but the risk of non-payment. We had our lever. The director followed up with tactical empathy: "I hear that your worry is being paid at all. That's legitimate."
Then the question that shifts the burden, a calibrated question: "How can we reassure you so that 60 days becomes acceptable?" The answer came of its own accord: a firm quarterly order and an initial deposit. We closed at net 60 days, in exchange for a volume commitment. The supplier gained visibility, the SME doubled its payment term. Nobody had lost face.
Trade, never concede for free
The cardinal principle: every concession calls for something in return. You want 60 days? Offer guaranteed volume, partial exclusivity, digital payment that speeds up processing. That's the logic of give and take. And when the buyer across the table demands a term you refuse, produce a concession you've prepared, one that costs you little but is prized in their eyes: a 1.5% discount for payment at 15 days often costs less than an extension you're forced to swallow.
Hold your line without breaking it
If the discussion hardens, the withdrawal remains your best signal of seriousness: "On these terms, it isn't viable for us, let's pick this up again when a compromise is possible." Nine times out of ten, that relaunches the negotiation on a healthier footing. Finally, root your requests in reality with social proof: "Our other partners in the sector work at 60 days." A shared norm defuses the sense of being singled out. To pinpoint the technique suited to your precise situation, explore the library, and rehearse your responses on the simulator before the real meeting.
FAQ
How do I ask for a longer payment term without looking like a bad payer?
Anchor your request to a structural reason, not a difficulty: alignment with your own collection terms, a volume order, a lasting relationship. Put a figure on the trade-off you're offering and lean on objective criteria (sector norms, statutory cap). A term justified by a flow logic can be negotiated; a term justified by a cash-flow hole raises alarm.
What should I do if the supplier flatly refuses to budge on their terms?
First check the strength of your fallback: an alternative supplier, a factoring facility or an early-payment discount changes everything. Then isolate the real obstacle with a calibrated question ("What would make 60 days possible?"). The refusal often has less to do with the deadline than with perceived risk, secure that risk, and the term becomes negotiable.
