Terms of Service

Effective Date: July 15, 2026

These Terms of Service (“Terms”) govern your access to and use of Stonaris, including our website, software platform, bookkeeping tools, reporting tools, integrations, and related services (collectively, the “Services”).

These Terms are a legal agreement between you and Ecomessence LLC, doing business as Stonaris (“Stonaris,” “we,” “us,” or “our”). By accessing or using the Services, you agree to these Terms. If you do not agree, do not use the Services.

1. About Stonaris

Stonaris is automated bookkeeping software for ecommerce sellers, starting with Amazon sellers. Stonaris connects to the accounts you authorize, books your Amazon settlements, categorizes your business transactions, and produces financial reports and tax-ready summaries.

Stonaris is a software company, not a bank, and the Services do not hold your money or move your money. Additional financial services may be offered in the future; if they are, they will be governed by separate or supplemental terms presented to you at that time.

2. Eligibility

To use Stonaris, you must:

  • Be at least 18 years old
  • Use the Services for business purposes only
  • Have authority to bind the business you represent
  • Provide accurate and complete information
  • Comply with these Terms and all applicable laws

We may refuse, suspend, or terminate access at any time if we determine that you or your business are not eligible, present unacceptable risk, or violate these Terms or applicable law.

3. Account Registration

You may need to create an account to use the Services. You agree to provide accurate, current, and complete information and to keep it updated.

You are responsible for:

  • Maintaining the confidentiality of your login credentials
  • All activity under your account
  • Ensuring authorized users comply with these Terms
  • Promptly notifying us of unauthorized access or security concerns

We may require multi-factor authentication or other security controls.

4. Amazon and Third-Party Integrations

Stonaris allows you to connect third-party services, including Amazon Seller Central, Amazon Ads, and your business bank and card accounts through our data providers.

These connections are read-only. They allow Stonaris to receive your data; they do not allow Stonaris to move your money, change your listings or prices, or take any action in your accounts.

By connecting a third-party account, you authorize Stonaris to access, receive, store, and process data from that third party as needed to provide the Services, including bookkeeping, reconciliation, expense tracking, reporting, tax-readiness, profitability visibility, and support.

You represent that you have the legal right and authority to connect each third-party account and authorize Stonaris to access and process the data.

You may disconnect integrations at any time, but some features may stop working if you do.

Third-party services are governed by their own terms and policies. Stonaris is not responsible for third-party services, outages, data inaccuracies, API changes, delays, or errors, including outages or errors at Amazon or our banking data providers.

5. Bookkeeping and Reporting

Stonaris provides software tools for bookkeeping automation, transaction categorization, Amazon settlement parsing, reconciliation, expense tracking, profit visibility, and financial reporting.

Stonaris is not a certified public accountant, tax preparer, law firm, investment adviser, or financial adviser. The Services are not legal, tax, accounting, investment, or financial advice.

Your books are prepared from the data you connect and the answers you confirm. You are responsible for:

  • Reviewing your books and reports
  • Confirming the accuracy of transaction categories
  • Providing complete and accurate information, including product costs
  • Consulting qualified tax, accounting, legal, or financial professionals
  • Filing taxes and regulatory reports correctly and on time
  • Maintaining required business records

We may use software, rules, automation, machine learning, or artificial intelligence to categorize transactions, parse settlement data, and generate reports. Automated outputs may be incomplete, inaccurate, delayed, or require review. You should not rely solely on automated outputs without review.

6. Estimates

Some numbers in the Services are clearly labeled as estimates — for example, today's profit, current-month storage fees, and open-period sales previews. Estimates are previews built from incomplete or provisional data. They are not bookkeeping records, they do not appear in your books or financial statements, and they may change as final data arrives. Do not rely on estimates for tax, accounting, or financial decisions.

7. Taxes

Stonaris may help organize financial data and generate tax-ready reports, but Stonaris does not file taxes for you unless a separate service is expressly offered and agreed in writing.

Tax-ready means that Stonaris attempts to organize and present financial information in a format that may be useful for tax preparation. It does not guarantee that your taxes are complete, accurate, compliant, or accepted by any tax authority.

You remain responsible for all taxes, filings, payments, penalties, interest, and tax positions.

8. Fees and Billing

Stonaris is offered as a paid subscription with a free trial. Unless we state otherwise at signup:

  • New accounts receive a free trial; no payment card is required to start
  • Your subscription plan is assigned automatically from your trailing-12-month Amazon sales, detected from your settlement data
  • You choose monthly or annual billing; annual billing is twelve months for the price of ten
  • Founding pricing, where offered, remains locked while your subscription stays active
  • Payments are processed by Stripe; we do not store your card details
  • You may cancel at any time from your billing settings; your subscription runs through the end of the period you paid for

We may change list prices by providing notice where required. If you continue using the Services after a fee change becomes effective, you accept the updated fees.

9. Your Data

Your business data is yours. We access and process it only to provide and support the Services, as described in these Terms and our Privacy Policy.

  • You can export your books, reports, and transactions at any time from within the product
  • You can delete your account yourself from Settings; deletion is permanent
  • We retain only what the law, tax rules, or fraud prevention require us to keep after deletion

10. Acceptable Use

You agree not to use Stonaris for:

  • Illegal activity
  • Fraud
  • Deceptive practices
  • Unauthorized access
  • Personal, family, or household use
  • Infringing intellectual property rights
  • Circumventing Amazon, data-provider, or compliance rules
  • Uploading malware or harmful code
  • Interfering with the Services
  • Scraping, reverse engineering, or abusing the platform
  • Misrepresenting your identity, business, or ownership

We may suspend or terminate access if we believe your use violates these Terms, law, Amazon requirements, or risk policies.

11. Data Accuracy and Availability

Bookkeeping and reporting data depend on third-party systems, APIs, user input, processing timelines, and data availability.

We do not guarantee that data will always be complete, accurate, current, or available. You are responsible for reviewing important information before making business, tax, accounting, or financial decisions.

12. Security

We use reasonable administrative, technical, and physical safeguards designed to protect the Services. However, no system is perfectly secure.

You agree to:

  • Use strong passwords
  • Protect your credentials
  • Enable required security features
  • Limit access to authorized users
  • Notify us immediately of suspected unauthorized access
  • Keep your devices and systems secure

We are not responsible for losses caused by your failure to secure your account, credentials, devices, or authorized users.

13. Confidentiality

You may receive access to non-public information about Stonaris, including product features, pricing, technical information, security practices, business plans, or beta functionality. You agree not to disclose confidential information unless authorized in writing.

14. Intellectual Property

Stonaris and its licensors own all rights, title, and interest in the Services, including software, design, text, graphics, logos, trademarks, workflows, systems, and technology.

You receive a limited, non-exclusive, non-transferable, revocable right to use the Services for your internal business purposes, subject to these Terms.

You may not copy, modify, distribute, sell, lease, reverse engineer, or create derivative works from the Services except as permitted by law or authorized by us in writing.

15. Feedback

If you provide feedback, ideas, suggestions, or recommendations, you grant Stonaris a perpetual, worldwide, royalty-free, irrevocable right to use them without restriction or compensation.

16. Beta and Early Access Features

Some features may be offered in beta, pilot, or early access form. Beta features may be incomplete, inaccurate, unavailable, or changed at any time. We may modify, suspend, or discontinue beta features without notice.

17. Suspension and Termination

We may suspend or terminate your access to the Services at any time if:

  • You violate these Terms
  • You create legal, compliance, security, financial, or reputational risk
  • Required by law, Amazon, our data providers, or regulators
  • We suspect fraud, misuse, or unauthorized access
  • Your business is no longer eligible
  • You fail to pay fees
  • We discontinue the Services

You may stop using the Services at any time. Certain obligations survive termination, including payment obligations, confidentiality, intellectual property, disclaimers, limitation of liability, indemnification, and dispute provisions.

18. Disclaimers

The Services are provided “as is” and “as available.”

To the fullest extent permitted by law, Stonaris disclaims all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, accuracy, availability, security, and reliability.

We do not guarantee that:

  • The Services will be uninterrupted or error-free
  • Reports will be accurate or complete
  • Bookkeeping automation will classify every transaction correctly
  • Third-party integrations will remain available
  • Tax-ready reports will satisfy any tax authority or accountant
  • Any business outcome, savings, profit, or tax result will occur

19. Limitation of Liability

To the fullest extent permitted by law, Stonaris and its affiliates, officers, directors, employees, agents, partners, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, punitive, or lost profit damages, including loss of revenue, loss of data, business interruption, tax penalties, tax interest, missed filings, accounting errors, third-party failures, or reputational harm.

To the fullest extent permitted by law, Stonaris's total liability for all claims arising out of or related to the Services will not exceed the greater of:

  • The amount you paid to Stonaris for the Services in the twelve months before the event giving rise to the claim; or
  • $100

Some jurisdictions do not allow certain limitations, so some limitations may not apply to you.

20. Indemnification

You agree to defend, indemnify, and hold harmless Stonaris and its affiliates, officers, directors, employees, agents, partners, and service providers from any claims, damages, losses, liabilities, costs, and expenses, including reasonable attorneys' fees, arising out of or related to:

  • Your use of the Services
  • Your business
  • Your transactions
  • Your connected accounts
  • Your data
  • Your violation of these Terms
  • Your violation of law
  • Your violation of third-party rights
  • Your tax, accounting, or reporting obligations
  • Your fraud, negligence, or misconduct
  • Actions by your authorized users

21. Governing Law

These Terms are governed by the laws of the State of Texas, without regard to conflict of law principles.

22. Dispute Resolution; Arbitration; Class Action Waiver

Before filing a claim, you agree to contact us at support@stonaris.com and attempt to resolve the dispute informally for at least 30 days.

If the dispute cannot be resolved informally, you and Stonaris agree that any dispute, claim, or controversy arising out of or relating to these Terms or the Services will be resolved by binding individual arbitration administered by the American Arbitration Association under its rules, rather than in court. The arbitration will be conducted in Texas or, at your election, by remote means. Judgment on the award may be entered in any court of competent jurisdiction.

Either party may instead bring an individual claim in small claims court if it qualifies. Either party may also seek injunctive relief in court for infringement or misuse of intellectual property.

You and Stonaris each waive the right to a trial by jury and the right to participate in a class action, class arbitration, or representative action to the fullest extent permitted by law. Disputes may only be brought on an individual basis.

23. Changes to These Terms

We may update these Terms from time to time. If we make material changes, we will update the effective date and may notify you by email, in-app notice, or website notice.

Your continued use of the Services after updated Terms become effective means you accept the updated Terms.
