Most owners could tell you what their business sells. Far fewer could tell you who owns the code their developer wrote, whose terms govern their biggest customer contract, or what happens to their data if their main software supplier goes under. None of it feels urgent. It stays that way until a buyer’s due diligence, a contract dispute, or a falling-out with a supplier turns a comfortable assumption into a problem with a price tag.
Two things sit at the heart of this: the contracts that govern how you trade, and the intellectual property that is often the most valuable thing you own. “We paid for it” is the line we hear most, and for copyright work it is a potentially costly misunderstanding for a growing business. Paying for work does not, by itself, make you the owner of what was created. The law sets the default, and the contract can change it — but only if it was written to. Here is where the gaps tend to sit.
1. Whose terms govern — the battle of the forms
You send your terms with the quote. The customer sends back a purchase order with their terms on the reverse. Work begins. Whose terms apply? English courts usually work it through on ordinary offer-and-acceptance principles. The last set accepted by words or conduct will often prevail, but prior framework arrangements and the parties’ actual conduct can change the result — “last document wins” is not a complete rule. The practical answer is not to chase the last word in a paper exchange. It is to state expressly which terms govern, reject conflicting purchase-order terms, and get clear acceptance before work begins.
2. Limitation and exclusion: what the law lets you cap
Most terms try to limit liability, and not all those limits survive. In business-to-business contracts, the Unfair Contract Terms Act 1977 can subject certain exclusions and caps to a reasonableness test — in particular, exclusions of liability for negligence and clauses relied on where one party is contracting on the other’s written standard terms. It does not catch every negotiated cap. Consumer contracts are a different regime, governed principally by the Consumer Rights Act 2015. Some limits are off the table altogether: under section 2(1) of the Unfair Contract Terms Act 1977, liability for death or personal injury resulting from negligence cannot be excluded or restricted, and separately a party cannot exclude liability for its own fraud in inducing the contract. The lesson runs against instinct: a clause that fails an applicable test may be ineffective, leaving you without the protection you expected, so a sensible, defensible cap is worth more than an aggressive one a court may not uphold.
3. Indemnities: the clause people sign without reading
An indemnity can allocate loss differently from an ordinary damages claim. Depending on its wording, it may affect causation, remoteness, mitigation, who controls a third-party claim, and when payment falls due. That is exactly why the words matter: the courts construe the actual indemnity language rather than applying broad assumptions about what indemnities always do. An indemnity may also sit outside the general liability cap, if the definitions, carve-outs or cap mechanics say it does. Read every indemnity against the cap — if one quietly sits outside it, the cap is doing less than you think.
4. Service levels, payment, and change of control
Service level agreements are where a contract’s promises get real. The points worth checking are practical: how performance is measured and over what period, whether service credits are your only remedy or sit alongside a right to terminate, what happens on chronic or repeated failure, and what is excluded from the measurement. Service credits that are the sole remedy can cap your recovery far below your actual loss. Read the remedies as carefully as the targets.
Two more clauses earn their place. Payment terms decide your cash flow, so the right to interest and to suspend should be explicit. And change-of-control clauses, buried at the back, can let a customer or supplier walk away or renegotiate the moment you sell. If your key contracts can be ended on a change of control, that is a fact about how saleable your business is, not just a line in a contract.
5. Who owns your IP — and why “we paid for it” isn’t the test
For copyright and many design rights, the creator is usually the first owner — unless the work was made by an employee in the course of employment, or the parties agreed otherwise in writing. A legal assignment of copyright has to be in writing and signed by or on behalf of the person assigning it. Other rights, including patents and database rights, follow their own rules. So the question is never “did we pay?” It is “do we have a written assignment?” If not, you may be left relying on an implied licence whose scope, duration and transferability are uncertain. The employee position is the helpful one; work made by an employee in the course of employment usually belongs to the employer. That does not carry across to contractors, consultants, freelancers or agencies. A common gap is the developer or design agency, paid in full, who never assigned the copyright in the code, the designs or the brand assets they made.
The fix is far cheaper before there is a dispute. A properly drafted assignment from every contractor and developer who has created anything material, dealing with present and future rights, moral rights, and any third-party or open-source material in the work. Where the work is ongoing, build it into the engagement terms so it happens as a matter of course, not as something you chase years later once the freelancer has moved on. The fuller checklist, including the joint-ownership trap where an employee and a contractor build something together, is in the guide.
6. Software, SaaS, data rights and exit
Run your business on third-party software and the useful question is rarely “who owns the data” in the abstract. It is whether you have the rights, and the means, to get your data and configuration out and keep operating. Before you commit, and before you leave, check what you can export and in what format; whether there is an exit charge; what is deleted on termination; whether you hold backups independently of the provider; and what continuity applies if the supplier fails. “Our data” is a phrase many SaaS contracts quietly qualify. The contract, your own exit plan and your independent backups together decide whether the business keeps running when a platform relationship ends.
7. AI-assisted work, brand and the assets a buyer checks
AI-assisted work may qualify for copyright where there is enough human creative contribution. The position for output generated by a machine alone is less certain: UK law currently has a special provision for computer-generated works, but its application to modern generative AI is largely untested, and on 18 March 2026 the Government proposed removing that provision while keeping protection for qualifying AI-assisted human work. A right under a provider’s terms to use an output is not the same as owning copyright in it, or a guarantee that it does not infringe someone else’s rights. If you are building AI-generated material into a business asset, check that staff use approved tools only, that the human contribution is recorded enough to show provenance, and that the provider’s terms deal with training use, output rights and third-party material.
The rest of what a buyer checks is more familiar. Trade marks, and whether they are registered in the right name. Domains, and who they are registered to. Website copy and images, owned or merely licensed. And the customer data in your CRM — whether you can lawfully use and transfer it, which on a sale turns on the deal structure, the lawful basis, transparency and security, not on whether you call it “our data.” Gaps here rarely kill a deal. They slow it down and hand the buyer leverage.

One line on registered rights and disputes. This is the commercial and contractual side of IP: ownership, assignment, licensing and what your terms say. Where registration, enforcement or a specialist IP dispute is needed, we coordinate with specialist IP counsel while keeping the contracts, the ownership chain and the deal strategy aligned. |
The takeaway
Your contracts decide how you trade and what you are exposed to. Your IP is often the most valuable thing you own, and the most likely to be sitting on the wrong side of a missing signature. The cheapest time to fix either is now, while it is a tidy-up job and not a negotiation under pressure. If you are signing a significant contract, taking on a developer or agency, building something with AI, or thinking about a sale, send the paperwork our way first. Where the way you hold valuable IP raises a tax question, we work alongside our tax colleagues across the Fusion Consulting Group to get it right.
Quick answers
Does paying a freelancer transfer copyright?
Not by itself. For copyright work the creator is usually the first owner unless they have assigned it to you in writing. Employees are the main exception; contractors and agencies are not.
Which terms apply when a quote and a purchase order conflict?
Whichever set was accepted by words or conduct, judged on ordinary contract principles — not automatically the last document sent. The safe course is to state which terms govern and get acceptance before work starts.
Can a business limit its liability in its terms?
Often, but not without limit. Certain exclusions and caps can be tested for reasonableness. And under section 2(1) of the Unfair Contract Terms Act 1977, liability for death or personal injury resulting from negligence cannot be excluded or restricted; separately, a party cannot exclude liability for its own fraud in inducing the contract.
What should a SaaS exit clause cover?
Data and configuration export, the format and timescale, any exit charge, what is deleted on termination, independent backups, and continuity assistance if the provider fails.
