End User License Agreement

Effective date: June 30, 2026 · Last updated: June 30, 2026

This End User License Agreement ("Agreement" or "EULA") governs your access to and use of Attachly ("Attachly," the "Service"), operated by Hollis Technologies, Inc. By creating an account, connecting a QuickBooks® Online company, or otherwise accessing or using the Service, you agree to be bound by this Agreement. If you do not agree, you must not access or use the Service.

1. Scope

This Agreement is a legal contract between you ("you," "your," or "Customer") and Hollis Technologies, Inc., a Washington corporation ("Hollis Technologies," "we," "us," or "our"), governing your access to and use of Attachly, including any associated documentation, updates, and related services (collectively, the "Services"). Attachly is a file-synchronization tool that migrates document attachments from QuickBooks Desktop into QuickBooks Online and links each file to the corresponding record.

2. Definitions

  • "Authorized User" means any individual you authorize to access and use the Services on your behalf, including employees, contractors, and — on the Firm plan — your client companies and their representatives.
  • "Customer Data" means data you or your Authorized Users submit to, generate within, or transmit through the Services, including your document files, file manifests, and configuration settings.
  • "Intuit Data" means data accessed from your connected QuickBooks Online company through the Intuit API.
  • "Third-Party Service" means any third-party software or service (such as QuickBooks Online) that you connect to, or that supports, the Services.
  • "Order" means a one-time migration purchase or a recurring subscription to the Services.

3. License Grant

Subject to your compliance with this Agreement and payment of all applicable fees, Hollis Technologies grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services solely for your internal business purposes. You may permit Authorized Users to access the Services on your behalf, and you remain responsible for their compliance with this Agreement.

4. The Service; Modification of Your QuickBooks Data

You understand that the Services, when you direct them to run a migration, will create attachment records in your connected QuickBooks Online company and may delete those same attachment records when you use the undo feature. The Services are designed so that every file is accounted for, duplicates are skipped, and each created attachment is recorded so the migration can be reversed within the undo window. You are responsible for reviewing the verification report and for confirming results in your QuickBooks Online company.

5. Orders, Billing, and Refunds

5.1 Payment Through Stripe

Fees are billed and processed through our payment processor, Stripe. By placing an Order you authorize Stripe to charge your payment method for the applicable fees. Hollis Technologies does not directly collect or store your payment-card details.

5.2 Pricing

The Services are offered as one-time, per-company-file migration purchases priced by tier, and as a recurring Firm subscription for users migrating multiple client companies. Current plans, tiers, and pricing are published at attachlysync.com. The applicable one-time tier is determined by the number of files in your migration. We may modify our plans, features, or pricing; changes will not affect an Order already placed.

5.3 Subscriptions

Recurring subscriptions renew automatically for successive periods until cancelled. You may cancel at any time; cancellation takes effect at the end of the current billing period. Access continues until the end of the period for which you have paid.

5.4 Refunds

Except where required by applicable law, fees are non-refundable. Because the Services provide a one-click undo that reverses a completed migration within the undo window, you can reverse the changes made to your QuickBooks Online company without a monetary refund. Contact [email protected] with any billing questions.

6. Acceptable Use

You agree to use the Services only for lawful purposes and in accordance with this Agreement. You will not, and will not permit any Authorized User or third party to:

  • Use the Services in any manner that violates applicable laws, regulations, or third-party rights;
  • Upload or process content you do not have the right to process, or that is unlawful, infringing, or malicious (including malware);
  • Attempt to gain unauthorized access to the Services, other customers' data, or connected systems;
  • Interfere with or disrupt the Services, including through excessive or automated requests beyond documented limits;
  • Use the Services to build or operate a competing product, or to benchmark them for competitive purposes;
  • Violate Intuit's applicable terms in connection with your use of the QuickBooks Online integration.

7. Restrictions

Except as expressly permitted, you will not copy, modify, or create derivative works of the Services; reverse engineer, decompile, or disassemble the Services except to the extent permitted by law; sell, resell, rent, lease, sublicense, or otherwise transfer the Services; remove or obscure any proprietary notices; or circumvent any usage limits, access controls, or security measures.

8. Customer Data and Privacy

8.1 Ownership

As between you and Hollis Technologies, you retain all right, title, and interest in your Customer Data and your Intuit Data. You grant Hollis Technologies a limited, worldwide, non-exclusive license to access, use, store, process, and transmit Customer Data and Intuit Data solely as necessary to provide the Services and as permitted by this Agreement and our Privacy Policy.

8.2 Your Responsibility

You are solely responsible for the accuracy, quality, and legality of your Customer Data and for having all rights necessary to submit it to the Services and to authorize the QuickBooks Online connection.

8.3 Privacy Policy

Our collection, use, and disclosure of personal information is governed by our Privacy Policy at attachlysync.com/privacy, which is incorporated into this Agreement by reference.

8.4 Deletion

Uploaded document files and cached QuickBooks Online data are deleted on the retention schedule described in the Privacy Policy (by default, 30 days after a migration completes), and OAuth tokens are deleted when you disconnect a company.

9. Third-Party Services; QuickBooks Online

The Services integrate with QuickBooks Online, operated by Intuit Inc. Your use of QuickBooks Online is governed by Intuit's own terms and privacy policy, not by this Agreement. Hollis Technologies is not responsible for the availability, accuracy, or content of any Third-Party Service. You may disconnect a connected company at any time. We may modify, suspend, or discontinue an integration in response to changes by the third-party provider.

10. Intellectual Property

The Services, including all software, designs, text, graphics, and logos (excluding Customer Data and Intuit Data), are the exclusive property of Hollis Technologies and its licensors and are protected by intellectual property laws. Except for the limited license in Section 3, no rights are granted to you by implication or otherwise. "Attachly" and "Hollis Technologies" are trademarks of Hollis Technologies, Inc. "QuickBooks" and "QuickBooks Online" are trademarks of Intuit Inc., used for identification only.

11. Feedback

If you provide suggestions or other feedback regarding the Services, you grant Hollis Technologies a perpetual, irrevocable, worldwide, royalty-free, sublicensable license to use and incorporate it into our products and services without obligation to you.

12. Service Availability

We strive to keep the Services available but do not guarantee uninterrupted or error-free operation. The Services may be temporarily unavailable due to maintenance, updates, technical issues, or events outside our reasonable control. We may modify, suspend, or discontinue features at any time, and will use commercially reasonable efforts to provide notice of planned maintenance where practical.

13. Confidentiality

Each party may access the other's confidential or proprietary information ("Confidential Information"). The receiving party will use it only as necessary under this Agreement, protect it with at least reasonable care, and not disclose it except to personnel and advisors bound by comparable confidentiality obligations. Confidential Information excludes information that is or becomes public through no fault of the receiving party, was already rightfully known, is independently developed, or is rightfully obtained from a third party without restriction.

14. Warranty Disclaimer

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. TO THE MAXIMUM EXTENT PERMITTED BY LAW, HOLLIS TECHNOLOGIES DISCLAIMS ALL WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICES WILL MEET YOUR REQUIREMENTS, BE UNINTERRUPTED OR ERROR-FREE, OR THAT MATCHING RESULTS WILL BE COMPLETELY ACCURATE. YOU ARE RESPONSIBLE FOR REVIEWING MIGRATION RESULTS AND FOR MAINTAINING APPROPRIATE BACKUPS OF YOUR DATA, INCLUDING YOUR QUICKBOOKS COMPANY FILE.

15. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, HOLLIS TECHNOLOGIES AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AND AGENTS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY. OUR TOTAL CUMULATIVE LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE SERVICES WILL NOT EXCEED THE TOTAL FEES YOU PAID TO HOLLIS TECHNOLOGIES IN THE TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE EVENT GIVING RISE TO THE LIABILITY. SOME JURISDICTIONS DO NOT ALLOW CERTAIN LIMITATIONS, SO SOME OF THE ABOVE MAY NOT APPLY TO YOU.

16. Indemnification

You agree to indemnify, defend, and hold harmless Hollis Technologies and its officers, directors, employees, and agents from any claims, liabilities, damages, losses, and expenses (including reasonable attorneys' fees) arising out of or relating to: (a) your use of the Services in violation of this Agreement; (b) your Customer Data or Intuit Data, including any claim that it infringes third-party rights; (c) your violation of applicable law; or (d) your violation of the rights of any third party.

17. Termination

You may terminate this Agreement at any time by ceasing use of the Services and disconnecting your QuickBooks Online companies. We may suspend or terminate your access, with or without notice, if you breach this Agreement, fail to pay, are required by law, if we discontinue the Services, or if we reasonably determine your use poses a security, legal, or operational risk. Upon termination, your right to use the Services ceases and Customer Data and Intuit Data are deleted in accordance with our Privacy Policy. Sections 8, 10, 11, 13, 14, 15, 16, and 18–20 survive termination.

18. Changes to This Agreement

We may modify this Agreement from time to time. When we make material changes, we will update the "Last updated" date above and, where appropriate, notify you by email or in-app. Your continued use of the Services after the effective date constitutes acceptance of the updated Agreement.

19. Governing Law and Dispute Resolution

This Agreement is governed by the laws of the State of Washington, United States, without regard to conflict-of-laws principles. Any legal action arising out of or relating to this Agreement will be brought exclusively in the state or federal courts located in Snohomish County, Washington, and each party consents to the personal jurisdiction and venue of those courts. Before filing a formal claim, the parties agree to attempt informal resolution by contacting [email protected] and negotiating in good faith for at least thirty (30) days. Either party may seek injunctive relief to protect its intellectual property or Confidential Information.

20. General Provisions

This Agreement, together with our Privacy Policy, is the entire agreement between you and Hollis Technologies regarding the Services and supersedes prior agreements. If any provision is held unenforceable, the remaining provisions remain in effect. No waiver is effective unless in writing. You may not assign this Agreement without our prior written consent; we may assign it in connection with a merger, acquisition, or sale of assets. Neither party is liable for failures due to causes beyond its reasonable control. The parties are independent contractors. Notices to Hollis Technologies must be sent to [email protected].
