- Price
- Payment schedule
- Expected timescale
- Included revisions
- Licensing and usage rights
- Client responsibilities

Unless a different period is stated, a quotation remains open for acceptance for 30 days.
A project becomes confirmed when the Client accepts the quotation or proposal in writing and satisfies any stated deposit or advance-payment requirement.
If a Project Agreement conflicts with these Terms, the Project Agreement will take priority only in relation to the specific matter it expressly changes.
A1Korbz may decline a project before acceptance where capacity, timing, subject matter, suitability or another reasonable concern would prevent delivery to the required standard.
5. Client Brief and Responsibilities
The Client is responsible for:
- Providing a clear and accurate brief

A1Korbz is entitled to rely on information and instructions supplied by the Client.
If information is incomplete, inaccurate or delivered late, the price, scope or delivery timetable may need to change.
6. Client-Supplied Materials
The Client retains ownership of materials supplied to A1Korbz.
The Client confirms that they have the necessary rights and permissions to provide those materials and to authorise their use for the project.
Client-supplied materials must not unlawfully infringe copyright, confidentiality, privacy or other third-party rights.
The Client should remove unnecessary personal or sensitive information before sending files. Confidential or particularly sensitive material should be discussed before transmission.
A1Korbz will use supplied materials only as reasonably necessary to assess, manage and complete the project, subject to the Privacy Policy and any separately agreed confidentiality terms.
7. Fees and Payment
Fees will be agreed before work begins.
Depending on the project:
- Full payment may be required in advance.
- A deposit may be required before work begins.
- Larger projects may be invoiced in stages.
- Organisational clients may be invoiced after delivery or according to an agreed purchase-order process.
The applicable arrangement will be stated in the quotation or invoice.
Payments are made by bank transfer unless another method is agreed.
Invoices must be paid within the period stated on the invoice. If no period is stated, payment is due within 30 days of the invoice date.
The Client is responsible for providing any purchase order or internal approval needed before work begins.
8. Late Payment
If an invoice remains unpaid after its due date, A1Korbz may:
- Issue a payment reminder
- Pause active work
- Withhold undelivered files
- Delay further revisions
- Decline additional work until the account is brought up to date
For Business Clients, A1Korbz reserves the right to claim statutory interest and applicable debt-recovery costs under late-payment legislation.
Any action taken in relation to late payment will be reasonable and proportionate.
9. Delivery and Timescales
The expected delivery date or timetable will be stated in the Project Agreement where possible.
A1Korbz will use reasonable care to meet agreed deadlines. The timetable may be affected by:
- Changes to the brief
- Additional requests
- Delayed files or instructions
- Delayed Client feedback
- Late payment

If a delay becomes likely, A1Korbz will notify the Client and provide an updated timetable where reasonably possible.

Digital delivery may be made by email, download link, cloud-storage link or another agreed method.
10. Review, Revisions and Corrections
The number and type of revisions included will be stated in the Project Agreement.
Unless otherwise agreed:
- Minor amendments within the original brief may be included.
- Changes to the brief are not included as revisions.
- New content, additional versions or substantial restructuring may incur an additional fee.
- Repeated or conflicting revision requests may require a revised scope.
The Client should review delivered work promptly and report any apparent error or departure from the agreed brief within a reasonable period.
Where A1Korbz has made an error or the deliverables do not conform to the agreed brief, A1Korbz will take reasonable steps to correct the issue without an additional fee.
Nothing in this section limits a Consumer’s statutory rights.
11. Changes to the Project
Either party may propose a change to the project.
A change may affect:
- The price
- Deliverables
- Timescale
- Number of revisions
- Required formats
- Licensing terms
A significant change will not be incorporated until its effect has been agreed in writing.
A1Korbz is not required to undertake work outside the agreed scope without an additional agreement.
12. Cancellation by Business Clients
A Business Client may request cancellation by contacting A1Korbz in writing.
If cancellation occurs after work has begun, the Business Client must pay for:
- Work completed up to the cancellation date
- Time reasonably committed to the project
- Any agreed milestones already completed
- Non-recoverable costs reasonably incurred for the project
Any advance payment will be applied against these amounts. Where the advance payment exceeds the amount properly due, the balance will be refunded.
A1Korbz will not impose a cancellation charge greater than the reasonable loss and cost resulting from the cancellation.
13. Consumer Cancellation Rights
If you are a Consumer and the contract is concluded online, by email or otherwise at a distance, you may have a legal right to cancel the service contract within 14 days after the day on which the contract is entered into.
You may cancel by sending a clear statement to:
You do not need to provide a reason.
Starting Work During the Cancellation Period
If you want A1Korbz to begin work during the 14-day cancellation period, you must make an express request.
If you then cancel before the service is completed, you may be required to pay a proportionate amount for work properly performed before cancellation.
Once the service has been fully performed, the right to cancel may be lost where:
- You expressly requested that work begin during the cancellation period; and
- You acknowledged that the cancellation right would be lost once the service was fully performed.
These cancellation rights do not affect your rights where a service has not been carried out with reasonable care and skill or does not otherwise comply with applicable consumer law.
14. Cancellation by A1Korbz
A1Korbz may cancel or terminate a project where:
- The Client materially breaches the agreement
- An invoice remains overdue after reasonable notice
- Required information is not supplied
- Communication breaks down to the extent that the project cannot reasonably continue
- Supplied material raises legal, ethical or rights-related concerns
- Continuing the project would be unlawful
- Illness or circumstances outside reasonable control prevent completion
Where A1Korbz cancels for reasons unrelated to a Client breach, the Client will receive a refund for paid work that has not been delivered.
Where cancellation results from a Client breach, A1Korbz may charge for work properly completed and reasonable costs already incurred.
15. Intellectual Property
15.1 A1Korbz Materials
A1Korbz retains ownership of:
- Pre-existing templates
- General production methods
- Reusable code and commands
- Document structures
- Style systems
- Technical processes
- General know-how
- Materials not created specifically for the Client
15.2 Bespoke Deliverables
Unless otherwise stated in the Project Agreement, copyright in original deliverables created by A1Korbz remains with Adrian Korban.
Once full payment has been received, the Client is granted a non-exclusive, non-transferable licence to use the deliverables for the purpose agreed in the Project Agreement.
15.3 Commercial and Publishing Rights
Rights for any of the following must be expressly agreed:
- Commercial publication
- Resale
- Sublicensing
- White-label use
- Platform-wide distribution

Any agreed commercial licence or copyright assignment should be recorded in the quotation, purchase order, commissioning agreement or another written document.
15.4 Source and Editable Files
LaTeX source, TikZ source, PGFPlots source, Word files, MathType files, templates and other editable materials are included only where stated in the Project Agreement.
Receipt of an editable file does not automatically transfer copyright or grant rights beyond the agreed licence.
15.5 Full Payment
No licence or transfer of rights takes effect until all amounts due for the relevant project have been paid in full.
16. Portfolio Use and Confidentiality
A1Korbz will not knowingly publish confidential Client materials or identify confidential projects without permission.
A1Korbz may ask for permission to display selected deliverables or anonymised extracts in a portfolio, website or promotional material. The Client is free to decline.
Confidentiality obligations stated in a separate non-disclosure agreement or commissioning contract will take priority where applicable.
General knowledge, skills and techniques developed through performing a project may be used in future work, provided confidential information and Client-owned material are not disclosed or reproduced unlawfully.
17. Mathematical and Subject-Specific Approval
A1Korbz will perform agreed services with reasonable care and skill.
Where mathematical review is expressly included, A1Korbz will apply appropriate mathematical expertise to the agreed scope. However, the Client remains responsible for final approval and suitability within its own publication, platform, curriculum, assessment or organisational process.
For scientific, engineering, financial, legal or regulated documents, A1Korbz provides mathematical, visual and document-production support only unless another role is expressly agreed.
The Client is responsible for obtaining approval from an appropriately qualified specialist where professional, regulatory, safety or technical sign-off is required.
18. Academic Integrity and Appropriate Use
A1Korbz may support authors, researchers, educators and students with legitimate typesetting, formatting, diagram and document-production work.
A1Korbz will not knowingly produce assessed academic work intended to be submitted dishonestly as the Client’s own or assist with plagiarism, fraud or other academic misconduct.
A1Korbz may decline a request where its intended use creates a reasonable ethical or integrity concern.
19. Third-Party Requirements
The Client is responsible for identifying any requirements imposed by:
- Publishers
- Examination boards
- Awarding organisations
- Universities
- Platforms
- Regulators
- Employers
- Other third parties
A1Korbz will follow requirements supplied and agreed as part of the brief but cannot guarantee acceptance by a third party whose decision-making is outside A1Korbz’s control.
20. File Compatibility and Retention
A1Korbz will provide the output formats agreed in the Project Agreement.
The Client is responsible for confirming any required software versions, platform restrictions or technical specifications before work begins.
Differences in fonts, software, packages, operating systems or third-party applications may affect how editable files display or compile.
Completed source files and deliverables are normally retained for up to three years after final delivery, in accordance with the Privacy Policy. This retention period is not a substitute for the Client maintaining its own secure backups.
The Client should download, inspect and safely store all delivered files.
21. Limitation of Liability
Nothing in these Terms excludes or limits liability where doing so would be unlawful, including liability for:
- Death or personal injury caused by negligence
- Fraud or fraudulent misrepresentation
- A Consumer’s statutory rights
- Any liability that cannot legally be excluded or limited
21.1 Consumers
If the Client is a Consumer, A1Korbz is responsible for foreseeable loss or damage caused by a failure to comply with the agreement or to use reasonable care and skill.
A1Korbz is not responsible for business losses suffered by a Consumer where the service was commissioned wholly or mainly for private purposes.
21.2 Business Clients
For Business Clients, A1Korbz will not be liable for indirect or consequential loss, loss of profit, loss of revenue, loss of opportunity, loss of anticipated savings or loss arising from a third-party decision, except where such liability cannot legally be excluded.
Subject to the exceptions above, A1Korbz’s total liability to a Business Client arising from a project will not exceed the total fees paid or payable for that project.
The Client is responsible for maintaining appropriate backups and for reviewing deliverables before publication, distribution or operational use.
22. Events Outside Reasonable Control
Neither party will be responsible for delay or failure caused by events genuinely outside its reasonable control.
These may include serious illness, widespread service disruption, loss of essential utilities, cyber incidents, natural events, government action or failure of a critical third-party service.
The affected party should communicate the problem promptly and take reasonable steps to reduce its impact.
If the project cannot reasonably continue, the parties will discuss rescheduling, partial delivery or cancellation and an appropriate adjustment of fees.
23. Data Protection
Personal information is handled in accordance with the A1Korbz Privacy Policy.
The Client should not provide unnecessary personal, confidential or sensitive information.
If a project requires A1Korbz to process personal information on behalf of an organisation, additional data-protection terms may be required before work begins.
View the Privacy Policy
24. Complaints
If you are dissatisfied with a service, please contact A1Korbz promptly and explain:
- The project concerned
- The issue identified
- The outcome you are seeking
A1Korbz will review the matter and attempt to resolve it fairly and within a reasonable time.
Nothing in this section affects a Consumer’s statutory rights.
25. Ending the Agreement for Breach
Either party may end the agreement by written notice if the other party commits a serious breach and, where the breach can be remedied, fails to remedy it within a reasonable period after being asked to do so.
Ending the agreement does not remove rights, payment obligations or liabilities that arose before termination.
Terms relating to payment, intellectual property, confidentiality, liability, data protection and governing law continue where necessary after the agreement ends.
26. Changes to These Terms
A1Korbz may update these Terms & Conditions from time to time.
Changes will not retrospectively alter an already confirmed project unless both parties agree in writing.
The version applying to a project will normally be the version available when the project is confirmed, together with the relevant Project Agreement.
27. Governing Law and Jurisdiction
These Terms and any Project Agreement are governed by the law of England and Wales.
If the Client is a Business Client, the courts of England and Wales will have exclusive jurisdiction unless another arrangement is agreed in writing.
If the Client is a Consumer living elsewhere in the United Kingdom, nothing in these Terms removes any mandatory protection or right to bring proceedings in the courts available under applicable consumer law.
28. General Terms
If any provision of these Terms is found to be unlawful or unenforceable, the remaining provisions will continue to apply.
A failure or delay in enforcing a right does not waive that right.
No person other than the Client and A1Korbz has a right to enforce the agreement unless expressly agreed.
Neither party may transfer the agreement without the other party’s written consent, except where permitted by law or expressly agreed.
