Terms of service
These terms explain how Nexa Development works with clients: how a project starts, what each side is responsible for, who owns what, and what happens when things change. They are written in plain English deliberately.
1. Who we are
Nexa Development (“Nexa”, “we”, “us”) is a UK software studio that designs and builds bespoke software, automations and practical AI for businesses. These terms cover your use of this website and the work we do for clients.
Where you and Nexa have signed a separate project agreement, that agreement takes precedence over anything set out below. You can reach us at any time at admin@nexadevelopment.co.uk.
2. Quotes and engagement
Every piece of work starts with a written quote setting out the scope, the price and the timeline. Work begins once you accept that quote in writing; until then neither side is committed to anything.
Quotes are valid for 30 days from the date we send them. After that we may need to re-price, because availability and third-party costs move.
3. Prototypes
For projects we think are a good fit, we build a working prototype free of charge so you can see the idea before spending anything. A prototype is there to illustrate how a system could work — it is not production software and is not built to be deployed as it stands.
Prototypes remain Nexa’s property until a paid engagement begins, at which point the relevant work is folded into the project. Asking for one, or receiving one, places no obligation on either side to go further.
4. Payment
We invoice in stages. The stages, the amounts and the trigger for each are set out in the quote for your project, so you always know what is due and when.
Invoices are payable by the date shown on them. Late payment attracts statutory interest and compensation under the Late Payment of Commercial Debts (Interest) Act 1998. All prices exclude VAT unless we state otherwise.
5. Intellectual property
Full intellectual property in the bespoke code, designs and documentation we build for you transfers to you once we have received final payment for that engagement. Until then we retain ownership of it.
Pre-existing material works differently. Frameworks, libraries, open-source components and our own reusable tooling stay owned by whoever already owns them; you receive a licence to use them as part of the delivered work rather than the underlying rights.
6. Your responsibilities
We will need feedback, content, approvals and access to the systems and accounts the work touches. The timeline in a quote assumes you can supply these within the windows we agree together.
Where those are delayed, dates move — and for long delays we may need to re-plan or re-price the remaining work. Please also make sure you hold the rights to any content, data or credentials you pass to us.
7. Warranties and support
If you report a defect within the support period agreed for your project, we will fix it at no charge. That covers the work as we delivered it.
It does not cover code that someone else has modified, faults caused by third-party services outside our control, or changes made to the environment the software runs in. Beyond this, the software is provided without further warranty except where the law implies one that cannot be excluded.
8. Ongoing support and retainers
Many clients keep us on a monthly retainer after launch, for maintenance, small improvements and priority access to our time. What a retainer covers, and how much time it buys, is set out in the written agreement for it.
Retainers are billed monthly in advance, and either side may end one by giving a month’s written notice. Ending a retainer does not affect your ownership of completed project work, or the free defect-support period attached to it.
9. Liability
Our total liability in connection with an engagement is limited to the fees you have paid us for that engagement. We are not liable for loss of profit, revenue, data, goodwill or business opportunity, whether direct or indirect.
Nothing in these terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for anything else that cannot lawfully be excluded.
10. Confidentiality
Each of us will keep the other’s confidential information private and use it only for the purposes of the project. That includes business plans, customer data, pricing, source code and anything else a reasonable person would treat as confidential.
This does not apply to information that is already public, that either of us knew independently, or that we are required by law to disclose. These obligations continue after the engagement ends.
11. Data protection
We handle personal data in line with our Privacy Policy, the UK GDPR and the Data Protection Act 2018. Where we process personal data on your behalf we act on your written instructions and apply appropriate technical and organisational security measures.
If a project requires it, we will agree a data processing schedule covering the categories of data, the purposes and the retention periods before that processing begins.
12. Termination
Either of us may end an engagement by giving written notice. We will stop work in an orderly way and hand over what has been produced up to that point.
On termination we invoice for all work completed, including work in progress and any third-party costs already committed. The sections on intellectual property, confidentiality and liability continue to apply afterwards.
13. Governing law
These terms, and any engagement made under them, are governed by the law of England and Wales. The courts of England and Wales have exclusive jurisdiction over any dispute arising from them.
If something goes wrong we would always rather sort it out by talking first — email admin@nexadevelopment.co.uk and we will come back to you quickly.
Our Privacy Policy sets out how we handle personal data in more detail. If anything here is unclear, email admin@nexadevelopment.co.uk.
