Types of Commercial Contracts

We advise clients on the full range of commercial agreements and recommend the approach best suited to the nature of the business and the client’s strategic business objectives.

Commercial Contracts

Well-drafted commercial contracts are paramount to facilitating seamless transactions, regardless of the relationship's nature. Our experienced commercial contracts solicitors understand that well-crafted contracts will reduce uncertainty and the likelihood of disputes and provide practical solutions when things do not go to plan. Commercial contracts perform a wide range of business-critical functions, from protecting revenue and controlling costs, through to procurement, supporting outsourcing arrangements, and maximising the value of your business.

Terms and Conditions

Terms and Conditions (T&Cs) allocate risks through liability exclusion clauses in case of default. Industry-specific regulations may require tailored terms for legal compliance, underscoring the importance of expert advice. However, effectiveness hinges on realistic, well-communicated clauses, requiring expert guidance to uphold in court. We help you draft professional T&Cs to enhance your business' credibility, providing reassurance to both you and your customers by making it much easier to establish a breach of contract.

Setting Up Your Business

Navigating the complexities of business structures - sole trader, partnership, company, or limited partnership (LP) - requires understanding their unique advantages and distinctions. We offer in-depth guidance on the range of options available, ensuring you grasp the nuances and ramifications of each potential structure so you can navigate these critical decisions with confidence.

Data Protection

Irrespective of your business size or industry, understanding and complying all aspects of data protection and privacy laws is imperative. We are skilled in helping our clients navigate the intricacies of privacy law and UK GDPR, providing strategic advice to mitigate reputation risks and ensure adherence to evolving data protection standards.

Outsourcing Agreements

From pre-procurement planning and tender stage through to initial negotiations, implementation, dispute resolution and exit management, our outsourcing agreements solicitors advise on every stage of the outsourcing contractual life cycle. We have particular expertise in drafting and negotiating contract terms across IT, technology and other business-process or service-delivery models.

Frequently Asked Questions (FAQs)

What is commercial law?

Commercial law is the area of law that governs business relationships, commercial transactions and the contracts that support them. It covers a wide range of matters including the drafting, review and negotiation of commercial agreements, the allocation of risk between parties, and the legal framework that helps businesses operate effectively, protect their interests and achieve their commercial objectives.

When should a business instruct a commercial contracts solicitor?

A business should instruct a commercial contracts solicitor whenever it is entering into, reviewing, negotiating or seeking to enforce an important commercial agreement. Early legal advice is particularly valuable where contracts involve significant risk, high-value commitments, complex service arrangements, IT or technology projects, outsourcing, or terms that may have a long-term operational or financial impact on the business.

What types of commercial contracts do you advise on?

We advise on a wide range of commercial contracts, including customer and supplier agreements, standard terms and conditions, service agreements, outsourcing contracts, IT and technology agreements, distribution and agency agreements, confidentiality agreements and other B2B and B2C commercial arrangements.

What should I do before signing a commercial agreement?

Before signing a commercial agreement, you should ensure that the contract accurately reflects the commercial deal, clearly allocates risk, and contains terms that are practical for your business to comply with in day-to-day operation. It is also important to understand key provisions relating to payment, liability, termination, service levels, intellectual property, confidentiality and dispute resolution, so that any legal or commercial issues can be identified and addressed before the agreement is finalised.

How can I protect my business from a commercial lawsuit?

The risk of a commercial lawsuit can often be reduced through well-drafted commercial contracts, effective internal procedures and early legal advice. Businesses can protect themselves by ensuring their contracts accurately reflect the agreed commercial terms, allocate risk appropriately, include suitable limitation of liability and commercial dispute resolution provisions.

Do small and medium-sized businesses need commercial law solicitors?

Yes. Small and medium-sized businesses can benefit significantly from commercial law advice, particularly when entering into important contracts, negotiating key terms or managing legal risk in commercial relationships. Instructing a commercial law solicitor at the right stage can help ensure that agreements are properly drafted, commercially workable and aligned with the business’s objectives, while reducing the risk of disputes, unexpected liability and costly problems later on.
