Terms of Service

Last updated: 11 June 2026

1. Agreement to These Terms

These Terms of Service ("Terms") govern your use of opexcel.app (the "Service"), operated by Opexcel ("we", "our", "us"). By creating an account or using the Service you agree to these Terms. The Service is provided for use by businesses and sole traders selling on Amazon; by using it you confirm that you are acting in the course of business and not as a consumer.

2. The Service

Opexcel is an analytics and operations dashboard for Amazon sellers: order tracking, sales and profit analytics, cost-of-goods (COGS) management, repricing tools, inventory and shipment tracking, deal monitoring and related features. The Service connects to your Amazon Selling Partner account with your authorisation and presents data retrieved on your behalf. We may add, change or remove features as the Service evolves.

3. Accounts and Acceptable Use

  • Provide accurate account information and keep your sign-in credentials secure. You are responsible for activity under your account.
  • Only connect Amazon seller accounts that you own or are authorised to manage.
  • Do not misuse the Service: no attempts to access other users' data, no interfering with or disrupting the Service, no reselling or redistributing data feeds obtained through the Service, and no use of the Service for unlawful purposes.
  • We may suspend access to protect the Service or other users while we investigate suspected misuse.

4. Financial Figures Are Estimates

All profit, fee, ROI, margin and VAT figures shown anywhere in the Service are estimates, produced for decision-support only. They are calculated from data sources that can be incomplete, delayed or inaccurate, and they do not constitute financial, tax, accounting or legal advice.

You must verify all figures against your own Amazon settlement data and your own records, and consult a qualified accountant or tax adviser before relying on any figure for pricing, purchasing, VAT, tax or accounting decisions. To the maximum extent permitted by law, we accept no liability for decisions made in reliance on estimated figures.

5. Repricing and Automated Actions

Repricing and other automation features execute price changes that you configure. You set the rules, floors, targets and triggers, and the Service submits price changes on your instruction. You retain full responsibility for your listing prices and for the outcomes of any price change made through the Service, including the consequences of rules you misconfigure. Review your repricing configuration carefully — we do not guarantee Buy Box placement, sales volume or any particular commercial outcome.

6. Your Responsibilities

You are responsible for:

  • Your own compliance with Amazon's terms, policies and programme requirements, including listing, pricing and restricted-product rules.
  • Verifying that products you source and list are permitted for sale — the Service does not warrant that any product is permitted on Amazon.
  • The accuracy of data you upload (such as cost-of-goods figures), on which your analytics depend.
  • Your own VAT, tax and accounting obligations.

7. Third-Party Services

The Service relies on third-party data sources and services, including the Amazon Selling Partner API and Keepa. Your use of Amazon's services remains governed by your agreements with Amazon. Third-party data can be delayed, incomplete or wrong, and we are not responsible for the availability or accuracy of third-party services.

8. Data Protection

Personal data is handled as described in our Privacy Policy, which forms part of these Terms.

9. Availability and No Warranty

The Service is provided "as is" and "as available", without warranties of any kind, whether express or implied. We do not warrant that the Service will be uninterrupted or error-free, or that data shown will be accurate or complete. We may suspend the Service for maintenance or to protect its integrity.

10. Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for any indirect or consequential loss, or for loss of profits, revenue, business, data or goodwill, arising out of or in connection with the Service. Our total aggregate liability to you arising out of or in connection with the Service shall not exceed the greater of (a) the fees you paid to us in the 12 months preceding the event giving rise to the claim, and (b) £100.

Nothing in these Terms excludes or limits liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot be excluded or limited under the law of England and Wales.

11. Termination

You may stop using the Service and request closure of your account at any time. We may suspend or terminate your access immediately if you materially breach these Terms, or on reasonable notice if we discontinue the Service. On termination your right to use the Service ceases; clauses which by their nature should survive — including sections 4, 9, 10 and 13 — continue to apply.

12. Changes to These Terms

We may update these Terms from time to time. The updated version will be posted on this page with a revised "Last updated" date, and your continued use of the Service after changes take effect constitutes acceptance of the updated Terms.

13. Governing Law

These Terms, and any dispute or claim arising out of or in connection with them, are governed by the law of England and Wales, and the courts of England and Wales have exclusive jurisdiction.
