Terms of service

1. Scope

These terms govern services provided by Trivellu, company registration number [REGISTRATION NUMBER], Islamabad, Pakistan. They apply alongside the individual proposal or statement of work signed for your project. Where the two conflict, the signed proposal wins.

2. Proposals and scope

Every engagement starts with a written proposal setting out deliverables, timeline, price and payment milestones. A proposal is valid for [NUMBER] days from issue. Work begins when you accept it in writing and the first milestone payment clears.

Fixed-price means fixed scope. Changes to scope are handled by written change order with an agreed price adjustment before the extra work starts. We will not do unagreed work and then invoice for it.

3. Fees and payment

• Prices are quoted in [CURRENCY] and exclude any taxes, duties or bank charges applicable in your jurisdiction.
• Invoices are payable within [NUMBER] days of issue.
• We accept bank transfer, Payoneer and Wise. Transfer fees are borne by the payer.
• Late payment beyond [NUMBER] days entitles us to suspend work after written notice.

4. Your responsibilities

Projects depend on timely input from you: access to systems and data, decisions when we ask for them, and a named point of contact. Where a delay on your side pushes the timeline, we will tell you in writing and agree a revised date rather than absorb it silently.

5. Intellectual property

On receipt of final payment, all intellectual property in the deliverables created specifically for you — source code, models, prompts, configuration and documentation — transfers to you outright.

We retain ownership of our pre-existing tools, libraries and general know-how, and grant you a perpetual, non-exclusive licence to use them as embedded in your deliverables. Third-party open-source components remain under their own licences, which we list at handover.

We will not resell or reuse your specific solution for another client.

6. Confidentiality

Each party keeps the other's confidential information in confidence and uses it only for the engagement. This survives the end of the engagement by [NUMBER] years. We will sign your own NDA where you prefer it.

7. AI-specific terms

Machine learning systems are probabilistic. We will state expected accuracy ranges for any model we deliver and test against them, but we do not warrant that a model will be correct in every case. You are responsible for human review where an incorrect output could cause harm, and for the lawfulness of the use case in your jurisdiction — including, where relevant, obligations under the EU AI Act.

Where generative output is delivered, you are responsible for final clearance of the content you publish. We will disclose which tools produced it.

8. Warranty and support

We warrant that deliverables will materially conform to the agreed specification for 30 days after acceptance, and we will fix defects in that period at no charge. This does not cover faults caused by your changes, third-party service failures or use outside the agreed specification.

9. Limitation of liability

Neither party excludes liability for fraud, wilful misconduct or anything that cannot be excluded by law. Subject to that, our total liability arising from an engagement is limited to the fees paid under that engagement, and neither party is liable for indirect or consequential loss, including lost profits or lost data.

10. Termination

Either party may terminate an engagement on [NUMBER] days' written notice. On termination you pay for work completed and accepted to that date, and we hand over everything produced up to that point.

11. Governing law

These terms are governed by the laws of [JURISDICTION], and the courts of [JURISDICTION] have exclusive jurisdiction. The parties will attempt good-faith resolution before starting proceedings.

Note: clients in the EU frequently ask for their own jurisdiction here. Decide your default position with a lawyer before publishing.
