Negotiating your terms of sale is not a legal exercise, it is a commercial balance of power. The client who reads your general terms and conditions of sale line by line is not disputing your rights: they are testing your firmness. Payment terms, late-payment penalties, price-revision clauses, retention of title, liability caps, deposit on order. Every comma weighs on your cash flow and your risk. The classic mistake is to give way on everything just to sign, then to bankroll the client for free for 90 days. Here is how to hold your terms without sinking the deal.
Tell what is negotiable from what is not
Before any meeting, settle it internally. Well-built terms of sale contain three circles: the non-negotiable clauses (retention of title, liability cap, governing law), the adjustable clauses (payment terms, instalment schedule, volume discount) and the trading clauses that you are willing to concede in return for something. Turning up without this map means improvising under pressure. The rule: you don't defend a clause because it is written down, you defend it because it protects real cash flow or a real risk. Document the cost of each concession. Moving from 30 to 60 days on a 200,000 euro contract ties up roughly 30,000 euros permanently.
Anchor your terms, don't let them be imposed on you
Whoever puts the first number on the table frames the whole discussion. Send your terms of sale up front, not as an attachment discovered at signing. Present "payment within 30 days, 30% deposit on order" as your standard, not as a proposal. This is anchoring: your opening position becomes the reference point from which the client negotiates, rather than the other way round. A buyer who wanted 90 days will often end up at 45 if they started from your 30, whereas they would have secured 60 had you let them open. And when they challenge your late-payment penalties, don't justify yourself: lean on objective criteria, in this case the statutory rate and the regulations on payment terms. A figure backed by an external standard is far harder to contest than a demand perceived as personal.
The story of the "non-negotiable 90 days"
A software publisher I was coaching had finally landed their big account: an industrial group, 240,000 euros of annual licensing. While reviewing the terms of sale, the buyer fired off a curt email: "Our group terms are 90 days end of month. It's our policy, it's non-negotiable." The founder, ready to sign, was about to accept. I stopped him.
First instinct, you don't push back head-on, you defuse through tactical empathy: "We understand that standardising payment terms is a structural matter for a group of your size." The buyer relaxes, they feel understood. Then, instead of counter-arguing, a calibrated question: "How are we supposed to fund twelve months of development on a 90-day settlement while guaranteeing your level of service?" Silence at the other end. We held that silence without filling it. It was the buyer who picked up: "What are you proposing?"
Then the give-and-take: "90 days is possible, on condition of a 40% deposit on signing and an annual indexed revision clause." By first stating a high demand we were prepared to drop, a prepared concession, we created room to manoeuvre. Final agreement: 60 days, 30% deposit, indexation. The cash flow was saved, and the buyer walked away convinced they had won.
Trade every concession, never give it away
The cardinal error: granting a longer term while getting nothing back. Every clause you let go of must be offset. The client wants 60 days instead of 30? You agree in exchange for a volume commitment, an automatic renewal clause, a customer reference or a firm twelve-month order. This principle of reciprocity turns erosion into balanced negotiation. And if the client demands a discount, present it by contrast: start from the full list price, then "come down" to your target price. The same discount looks twice as generous when it follows a high anchor point.
Prepare your fallback and know when to walk away
You will only hold your terms of sale if you are ready not to sign. Your fallback (BATNA), the other prospects in your pipeline, your order book, is your real leverage. A client who demands 120 days and no deposit isn't a client, it's a subsidised risk of non-payment. When the red line is crossed, the walkaway remains the most powerful argument: "On those terms, we won't be able to commit with any peace of mind." That step back often reframes the discussion in a single sentence. To sharpen these reflexes, practise on the simulator or find the right technique for each situation in the library.
FAQ
Should you send your terms of sale before or during the negotiation?
Always before. Sharing your terms up front, as soon as the commercial proposal goes out, lets you set the anchor and install your standards as the norm. Discovering the terms of sale at the point of signing reverses the balance of power: the client sees them as a last-minute obstacle and digs in. Sent early, they become the natural framework for the discussion.
How do you refuse an overly long payment term without losing the client?
Don't refuse head-on: put a calibrated question that shifts the weight of the constraint onto the client ("how do we fund the work on those terms?"), then propose a trade, a longer term against a larger deposit or a volume commitment. Lean on the objective criteria of the regulations on payment terms to depersonalise the refusal. A client gives way more readily to a standard than to your will.
