Commercial Contracts
Strategic legal contracts to fuel growth and protect your business
Your commercial contracts don’t just protect your business – they’re growth tools. Whether launching a product or expanding markets, we help start-ups and scale-ups create robust, flexible agreements that reduce risk and drive smarter decisions.
From SaaS to licensing, outsourcing to partnerships – we build contracts that support long-term success.
Experts in commercial contracts
Helping your business create and manage better contracts
We advise on the full range of commercial agreements – NDAs, agency and distribution agreements, service terms, SaaS and technology licences, outsourcing contracts and more.
Our work goes beyond drafting and negotiation. We help you:
Review and optimise underperforming agreements to remove risk, clarify terms and improve outcomes.
Audit contracts to uncover risks and missed opportunities that could impact revenue, liability or enforceability.
Build scalable templates and playbooks to streamline negotiations and reduce inconsistencies.
Advice on contract management tools to help you streamline, organise, and control every stage of the contract lifecycle.
Implement contract management workflows that grow with your business to simplify oversight and support compliance.
Resolve disputes when deals don’t go to plan to protect your commercial interests and minimise disruption.
We take you into account

All of our commercial contract lawyers have worked at partner level in top 100 law firms, or in-house at large international corporations. Find out more about each of our commercial contract solicitors here:
Testimonials
What our clients say
The two contracts Harper James has been advising on were both major pieces of work worth tens of millions of pounds in potential business. The procurement process was therefore substantial, complicated and often onerous. Karen provided first-class support at all times. As a business, to move forward, we require a level of legal services which demonstrate an expert understanding, and Harper James delivers on that and more.

Harper James have been incredibly professional and responsive. They immediately understood the challenges we have. Not only those of any small business, but those relating to building a piece of complex tech, and they have been able to help us navigate that from a legal perspective.

This is a key stage of ANB Sensors’ growth as an SME, because it saw us transferring from a research and development company to a commercial entity. It’s a major milestone for us. Having Harper James by our side is reassuring, as they’ve helped us ensure all our documentation and sales terms are both fair and reasonable and led us through the sales process.
Dr Nathan Lawrence
CEO and Co-Founder,
ANB Sensors
Harper James has been invaluable. They drafted the relevant agreements and gave us sound legal advice in an area that we did not have prior experience in. As a start-up, having advice and feedback from an organisation that specialises in early-stage enterprises was instrumental in us having the confidence to push forward with our product
Dean Bryan
Co-Founder,
Yyoma
Stephen was very helpful, pragmatic and where appropriate, entertaining. We were grateful for the way Stephen advised us in layman’s terms, showing patience to ensure we understood the transaction and were able to move to completion. I value the relationship we have developed with Harper James over the last few years and would recommend them to others.
Jon Arcos
Founder & CEO,

Harper James has been the ideal law firm for Paragraf because of the flexibility that’s built into the extend subscription package. With HJ, I have all the legal expertise and answers I need at the end of an email. We have ambitious plans to fulfil, pushing our product lines overseas and bringing graphene electronics to the masses. There’s no better partner to help us get there than Harper James.
Cathy Cranton

Having the Extend plan with Harper James gives us constant access to leading legal experts across the areas of law we need to keep growing our business. I’m convinced no one delivers better service or beatable value.

Harper James delivers exactly what I want from my lawyers; someone who presents not only the risks and the legal argument but who also understands the commercial side. Take our recent work with Sarah Gunton for example; if we decide we’re going to take on a commercial risk, she’ll adapt the terms for us to do that while reducing the risk as much as possible. The service we get there is like gold dust for us.
Craig Aston
COO,
Celerity Limited
I've had great experience in dealing with HJ, unlike any I've experienced in the past. There was care and attention in the drafting stage working out my exact requirements, not just legally but understanding how the business worked to advise further.

Commercial Partner, Rob Cobley, helped us do the necessary due diligence and guided us on which online age verification solution offered us the best legal protection. We needed to eliminate any reputational risk and wanted a ‘gold-standard’ solution that set us apart from any competitors. Getting it right with all the 'belts and braces' gave us comfort because there are several different providers who achieve age verification in different ways. Navigating and implementing the solution was made possible with Rob’s help.
