Commercial negotiation is a business process with a legal output. The objective is a signed agreement that reflects the commercial deal, allocates risk acceptably and can be operated by the people who have to live with it.
Deals stall for predictable reasons: no agreed scope, too many people involved, positions taken without understanding the underlying interest, and last-minute legal review of a contract that has already been informally agreed.
This guide sets out an approach that shortens negotiations and produces better contracts, whether you are the customer or the supplier.
Prepare before the first draft
Decide what a good outcome looks like, what you would walk away over, and what you will trade. Rank issues into must-have, would-like and nice-to-have, and identify what the other side is likely to want in return for each concession.
Understand your alternative. Knowing what happens if the deal does not close — another supplier, in-house delivery, delay — determines how much leverage you actually have. Negotiating without that clarity leads to concessions made under imagined pressure.
Control the paper
Whoever produces the first draft frames the negotiation. The default positions in that draft become the baseline and the other side spends the negotiation arguing away from it. Offering to prepare the document is rarely refused and is usually worth the drafting cost.
Where you must work from the counterparty's paper, respond with a marked-up version rather than a list of comments, so your wording is on the table. Keep one version-controlled document, use tracked changes and avoid parallel side-emails that create ambiguity about what was agreed.
Agree heads of terms first
A one- or two-page heads of terms covering scope, price, term, key liabilities and any deal-breakers takes an hour and prevents weeks of drafting on a misunderstood commercial basis.
Mark it 'subject to contract' and state which parts, if any, are binding — typically confidentiality, exclusivity and costs. Then have the lawyers document what has been agreed rather than discovering during drafting that the parties had different deals in mind.
The clauses actually worth fighting for
Focus effort on: the scope and specification, because most disputes are really about what was promised; payment terms and remedies for late payment; limitation and exclusion of liability, including the cap and the excluded loss types; indemnities and their caps; intellectual property ownership; termination rights and notice periods; and any change control mechanism.
Boilerplate deserves a quick check rather than a debate — but read the notices clause, the entire agreement clause, the assignment provision and the governing law and jurisdiction clause, because each has caught out businesses that assumed they were standard.
Techniques that work
Trade rather than concede: link every concession to something you receive. Where positions are entrenched, look for a different structure — a lower cap paired with insurance, a shorter term with renewal, a pilot phase before full commitment.
Escalate constructively. When two negotiators are stuck on principle, a short call between the commercial owners on each side often resolves in ten minutes what email has failed to resolve in three weeks. And keep a running issues list with agreed and outstanding points, so the endgame is a short list rather than a rediscovery of everything.
Closing and operating the contract
Before signature, check the schedules match the commercial deal, the defined terms are used consistently, dates and figures are correct, and the signature blocks reflect the correct legal entities. Entity errors are surprisingly common and undermine enforceability.
After signature, brief the people who will deliver. A contract that sits unread in a folder produces breaches by accident: missed notice deadlines, unclaimed service credits, uncharged indexation. Keep a contract register with key dates and obligations, and diarise renewal and break notices.
Key points
- Rank issues into must-have, would-like and nice-to-have before you start.
- Producing the first draft sets the baseline — offer to do it.
- Heads of terms prevent drafting on a misunderstood commercial basis.
- Scope, liability, IP and termination deserve most of the effort.
- Trade concessions rather than giving them away.
- Check entity names and schedules before signature; brief the delivery team after it.
Frequently asked questions
- Should I sign the other side's standard terms?
- Often you can negotiate them, even where a supplier says they are non-negotiable. At minimum, review liability, termination, IP and auto-renewal. If the counterparty genuinely will not amend, price the risk into the commercial deal.
- What is a battle of the forms?
- Where each party purports to contract on its own standard terms. English law generally applies the 'last shot' analysis, so the terms sent last and accepted by conduct usually prevail. Avoid it by agreeing expressly which terms apply.
- How long should a commercial contract be?
- As long as the risk requires. A low-value, low-risk supply arrangement can be a few pages. A business-critical outsourcing needs schedules and detail. Length for its own sake slows deals and creates inconsistency.
- Can we agree terms by email?
- Yes — an exchange of emails can create a binding contract if the essential terms are agreed and there is intention to be bound. Use 'subject to contract' in negotiations if you do not intend to be bound yet.
