Harper James advises start-ups, scale-ups and established companies on forming enforceable commercial agreements under the laws of England and Wales. A contract is formed when the parties reach agreement, intend legal relations, provide consideration, and use sufficiently certain terms, with the signatory having authority to bind the business.
The familiar model is offer and acceptance, but commercial negotiations rarely follow it neatly. An agreement can arise through signed documents, exchanged emails, acceptance of an order form, or conduct such as delivering goods after receiving an order. Directors and employees must have actual or apparent authority, and key terms should identify the parties, scope, price, term, service levels, liability position and termination rights. A deed follows different execution rules and does not require consideration.
Businesses often exchange their own standard terms, creating a “battle of forms”. The last set of terms sent and accepted before performance frequently becomes the contractual basis, but the result depends on the wording and sequence of communications. Procurement portals, purchase orders and supplier acknowledgements add further complexity. A practical guide to commercial contract formation should therefore be used alongside a clear contracting process, not as a substitute for reviewing the actual documents.
Electronic signatures generally provide a valid way to execute commercial contracts, provided the relevant formalities are met. Email acceptance, click-through terms and automated ordering systems can also create binding obligations. Businesses should retain the contract version, signature certificate, audit trail, signatory details and evidence of the terms displayed at the point of acceptance. Incorporating website terms by reference requires particular care: the other party must receive reasonable notice of the terms before contracting.
Current contracting practice focuses on reducing disputes about what was agreed, especially where teams use templates, e-signature platforms or AI-assisted drafting. A practical process includes an approved template, a contract owner, delegated signing limits, a record of negotiated changes, and a rule stating which document takes precedence if terms conflict. Before work starts, confirm the parties, authority, scope, pricing, variation procedure, governing law and termination rights. These steps protect the commercial deal while keeping negotiation proportionate to its value and risk.
