Terms of Service

Effective date: April 14, 2026Last updated: April 14, 2026

1. Agreement to These Terms

These Terms of Service (“Terms”) govern your use of tangadvisory.com (the “Website”) and certain interactions with Tang Advisory, the trade name of Tang Enterprises LLC, a Washington limited liability company and registered CPA firm (“Tang Advisory,” “we,” “us,” or “our”). By accessing or using the Website, or by submitting an inquiry through it, you agree to be bound by these Terms. If you do not agree, please do not use the Website.

These Terms apply to your use of the Website. Our professional services are governed by a separate, signed engagement letter between you and Tang Advisory, as described in Section 2.

2. Scope and Services

The Website provides general information about Tang Advisory and the services we offer, including tax preparation, bookkeeping, SOC 2 Type I and Type II examinations, and related advisory services. Website content is informational only. It is not, and should not be relied on as, accounting, tax, legal, audit, or cybersecurity advice for your specific situation.

Professional services are provided only under a written engagement letter executed by both parties. The engagement letter sets the scope, deliverables, fees, responsibilities, timing, confidentiality, limitation of liability, and dispute-resolution terms specific to that engagement. Where the engagement letter and these Terms conflict with respect to the professional engagement, the engagement letter controls.

3. No Professional Relationship from Website Use

Visiting the Website, submitting an inquiry through the contact form, booking a consultation through Calendly, or exchanging preliminary emails with us does not create a CPA-client, accountant-client, auditor-client, or any other professional relationship. A professional engagement begins only when (a) we deliver a written engagement letter to you, (b) you sign it, and (c) we countersign.

Until an engagement letter is in place, you should not rely on any statement we make, on the Website or otherwise, as advice specific to your facts. We have no obligation to accept any prospective client, and we may decline an engagement in our discretion (including for conflicts of interest, professional independence, or capacity reasons).

4. Use of the Website

You may use the Website for lawful, personal, informational purposes and to evaluate whether to engage us. You agree not to:

  • Use the Website in violation of any applicable law, regulation, or professional rule.
  • Scrape, crawl, harvest, or otherwise collect data from the Website by automated means, or use the Website to train machine learning or generative AI models, without our prior written consent.
  • Attempt to probe, scan, or test the vulnerability of the Website or any connected system, breach security or authentication measures, or interfere with or disrupt the Website.
  • Impersonate another person, misrepresent your affiliation, or submit false or misleading information through any form on the Website.
  • Upload or transmit any virus, worm, malicious code, or other harmful content.
  • Use the Website in a way that could reasonably be expected to damage Tang Advisory or expose us to liability.

The Website does not offer user accounts for the general public. Clients who are provisioned access to our client portal (currently TaxDome) are subject to the separate terms of that platform in addition to these Terms and their engagement letter.

5. Intellectual Property

All content on the Website — including text, graphics, logos, images, design elements, and the arrangement of the Website — is owned by Tang Advisory or our licensors and is protected by United States and international copyright, trademark, and other intellectual-property laws. “Tang Advisory” and any associated marks used on the Website are trademarks of Tang Enterprises LLC.

We grant you a limited, revocable, non-exclusive, non-sublicensable license to view and use the Website for your personal, non-commercial informational use. No other rights are granted. In particular, you may not reproduce, distribute, modify, publicly display, or create derivative works from Website content except as expressly permitted by applicable law (for example, limited fair use) or with our prior written consent.

6. Third-Party Links and Services

The Website links to, and our services use, third-party platforms, including Calendly (scheduling), TaxDome (client portal and practice management), Stripe (payment processing), Formspree (contact form delivery), Vercel (hosting), and Google Workspace (email and productivity). When you navigate to one of those services, you are subject to that provider’s own terms and privacy policy.

Tang Advisory does not control, and is not responsible for, the content, availability, accuracy, security, or privacy practices of any third-party website or service, and the inclusion of a link does not imply endorsement. You use third-party services at your own risk and subject to their terms.

7. Disclaimer of Warranties

THE WEBSITE AND ITS CONTENT ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT REPRESENTATIONS OR WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY. TO THE FULLEST EXTENT PERMITTED BY LAW, TANG ADVISORY DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT, AND ANY WARRANTIES ARISING FROM COURSE OF DEALING OR USAGE OF TRADE.

We do not warrant that the Website will be uninterrupted, error-free, secure, or free of viruses or other harmful components, or that any defects will be corrected. Information on the Website may contain inaccuracies or typographical errors and may be updated or changed at any time without notice. Tax laws, accounting standards, and cybersecurity frameworks change frequently; Website content may not reflect the most recent developments.

You should not act on Website content without first confirming the analysis with a qualified professional in the context of an engagement. This Section 7 applies to the Website. Warranties and disclaimers applicable to professional services, if any, are set forth in the engagement letter for that service.

8. Limitation of Liability

TO THE FULLEST EXTENT PERMITTED BY LAW, TANG ADVISORY, TANG ENTERPRISES LLC, AND THEIR OWNERS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, BUSINESS INTERRUPTION, OR COST OF SUBSTITUTE SERVICES, ARISING OUT OF OR RELATING TO YOUR USE OF THE WEBSITE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR AGGREGATE LIABILITY FOR ANY AND ALL CLAIMS ARISING OUT OF OR RELATING TO THE WEBSITE WILL NOT EXCEED THE GREATER OF (a) ONE HUNDRED U.S. DOLLARS ($100) OR (b) THE AMOUNT YOU HAVE PAID TO TANG ADVISORY IN THE TWELVE (12) MONTHS PRECEDING THE EVENT GIVING RISE TO THE CLAIM. LIABILITY FOR PROFESSIONAL SERVICES IS NOT GOVERNED BY THIS SECTION; IT IS GOVERNED EXCLUSIVELY BY THE APPLICABLE ENGAGEMENT LETTER.

Nothing in these Terms limits or excludes liability that cannot be limited or excluded under applicable law, including liability for fraud, willful misconduct, or gross negligence. Some jurisdictions do not allow certain limitations; in those jurisdictions, the limitations in this Section apply to the maximum extent permitted.

9. Indemnification

You agree to indemnify, defend, and hold harmless Tang Advisory, Tang Enterprises LLC, and their owners, employees, and agents from and against any claims, damages, liabilities, losses, costs, and expenses (including reasonable attorneys’ fees) arising out of or relating to (a) your misuse of the Website, (b) your violation of these Terms, (c) your violation of any law or of the rights of any third party in connection with your use of the Website, or (d) any content you submit through the Website. This indemnity does not apply to claims arising out of the professional services themselves, which are addressed in the applicable engagement letter.

10. Governing Law and Dispute Resolution

These Terms and any dispute arising out of or relating to them or your use of the Website are governed by the laws of the State of Washington, without regard to its conflict-of-laws rules. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

Before initiating any formal proceeding, the parties will attempt in good faith to resolve any dispute through direct discussion. If the dispute is not resolved within thirty (30) days after one party gives written notice of the dispute, the parties will submit the dispute to non-binding mediation in King County, Washington, with a mediator and under procedures to be mutually agreed, with mediation fees shared equally.

If mediation does not resolve the dispute within sixty (60) days after the mediator is selected, the dispute will be finally resolved by binding arbitration administered by the American Arbitration Association (“AAA”) under its Commercial Arbitration Rules, before a single arbitrator, seated in King County, Washington. Judgment on the award may be entered in any court of competent jurisdiction.

Waiver of jury trial and class actions. To the extent permitted by law, you and Tang Advisory each waive any right to a jury trial and any right to bring or participate in a class, collective, or representative action with respect to any dispute arising out of or relating to these Terms or the Website. Disputes must be brought in an individual capacity only.

Notwithstanding the above, either party may seek temporary or preliminary injunctive relief in a court of competent jurisdiction in King County, Washington to prevent actual or threatened infringement of intellectual-property rights, breach of confidentiality, or unauthorized access to systems.

11. Changes to These Terms

We may update these Terms from time to time. When we do, we will post the revised Terms on this page and update the “Effective date” and “Last updated” dates above. Changes are effective when posted. Your continued use of the Website after changes are posted constitutes acceptance of the updated Terms. If you do not agree with the updated Terms, you should stop using the Website.

12. Severability

If any provision of these Terms is held invalid, illegal, or unenforceable by a court or arbitrator of competent jurisdiction, that provision will be modified to the minimum extent necessary to make it enforceable, or severed if modification is not possible, and the remaining provisions will continue in full force and effect. Our failure to enforce any provision is not a waiver of that provision or of any other provision.

13. Entire Agreement

These Terms, together with our Privacy Policy and any additional policies we post on the Website, constitute the entire agreement between you and Tang Advisory with respect to your use of the Website, and supersede any prior or contemporaneous understandings on that subject. For clients with an active engagement, the signed engagement letter is the entire agreement with respect to the professional services described in it.
