All-In Accounting Solutions: Firm Technology

Effective Date: September 1, 2026 – Version 3.1

This Technology Use and End User License Agreement (this "Agreement") is a binding agreement between All-In Accounting Solutions, LLC, a Missouri limited liability company (the "Firm," "we," or "us"), and each person who accesses or uses any Firm Technology (as defined below). This Agreement applies to (i) each individual whom the Firm authorizes to access or use Firm Technology in the course of the Firm’s business (each an "Authorized User" as further defined in Section 1), and (ii) each client of the Firm, and each individual acting on a client’s behalf, who accesses Firm Technology or authorizes it to connect to the client’s accounts or data (each a "Client User"). This Agreement supersedes and replaces all prior end user license agreements governing any component of Firm Technology, each of which is now governed by this Agreement.

BY ACCESSING OR USING ANY FIRM TECHNOLOGY, YOU ACKNOWLEDGE THAT YOU HAVE READ, UNDERSTOOD, AND AGREE TO BE BOUND BY THIS AGREEMENT. Where the Firm presents this Agreement for acceptance (for example, at first login to a client portal), clicking or tapping "I agree" or a similar mechanism also constitutes acceptance of this Agreement. If you do not agree to this Agreement, you are not authorized to access or use Firm Technology.

(a) "Authorized User" means an employee, partner, member, or contractor of the Firm whom the Firm has expressly authorized in writing to access Firm Technology within the scope of that person’s duties for the Firm.

(b) "Client" means a client of the Firm. "Client User" has the meaning given in the introductory paragraphs of this Agreement and includes the Client and any individual the Client authorizes to act on its behalf in connection with Firm Technology. "You" refers to the Authorized User or Client User bound by this Agreement, as applicable.

(c) "Client Data" means all data, records, financial information, tax information, and other content of or relating to a Client that is provided to the Firm or accessed, retrieved, processed, transmitted, or stored through Firm Technology.

(d) "Credentials" means OAuth tokens, refresh tokens, API keys, passwords, multi-factor authentication factors, and any other authentication materials used by or in connection with Firm Technology.

(e) "Firm Technology" means all software, systems, tools, and services owned, operated, licensed, or made available by the Firm in connection with its professional accounting practice, including: (i) proprietary applications, software integrations, and connectors built by or for the Firm, including tools that connect to Third-Party Services; (ii) client portals, file-exchange and e-signature tools, and the non-public, authenticated portions of websites operated by the Firm (the Firm's public marketing website is not Firm Technology and is addressed by the Firm's Privacy Policy); (iii) the Firm’s internal systems, networks, devices, workpaper platforms, and communication tools; and (iv) analytics, automation, and artificial-intelligence-assisted tools used by the Firm in performing or supporting client services.

(f) "Third-Party Services" means products, services, platforms, and APIs made available by third parties and used by or connected to Firm Technology, including accounting and bookkeeping platforms, payroll and payment platforms, cloud hosting and storage providers, and tax and practice-management software.

This Agreement governs access to and use of Firm Technology. It does not define the professional services the Firm provides to any Client; those services are governed by the Client’s engagement agreement with the Firm. In the event of a conflict between this Agreement and a Client engagement agreement, the engagement agreement governs as between the Firm and that Client. Firm Technology is made available for use in connection with the Firm’s services only: it is not offered to the general public, is not listed on any app store or marketplace, and is not made available for download, resale, sublicense, or standalone use by any third party.

Part I: Terms Applicable to Authorized Users

Subject to your continued compliance with this Agreement, the Firm grants each Authorized User a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use Firm Technology solely to perform services for Clients and to conduct Firm business on behalf of the Firm, in accordance with Firm policies, this Agreement, applicable law, and applicable professional standards. All rights not expressly granted in this Agreement are reserved by the Firm. This license does not constitute a sale of any Firm Technology or any copy of it.

As an Authorized User, you shall not, and shall not permit or assist any other person to:

(a) access any Client account, accounting system, or other Client system without proper, current Client authorization;

(b) access, use, copy, or disclose Client Data for any purpose other than providing the services the Client has engaged the Firm to perform, or use Client Data for any personal benefit;

(c) sell, sublicense, rent, lease, distribute, publish, or otherwise make any Firm Technology, or any access to it, available to any third party;

(d) copy, export, or transmit Credentials outside of the Firm’s approved secure storage, or record Credentials in logs, documents, screenshots, messages, or source control;

(e) reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code of any Firm Technology, except to the extent such restriction is prohibited by applicable law;

(f) modify, adapt, or create derivative works of any Firm Technology without the Firm’s prior written consent;

(g) circumvent, disable, or interfere with any security, access-control, or audit feature of Firm Technology or of any Third-Party Service;

(h) transfer Client Data to any personal account, personal device, or unapproved application or service (including unapproved artificial-intelligence tools), or store Client Data anywhere other than Firm-approved systems;

(i) use Firm Technology to introduce any virus, malware, or other harmful code, or in any manner that could damage, disable, or impair Firm Technology or any Third-Party Service; or

(j) use Firm Technology in violation of the terms governing any Third-Party Service (including any developer or platform terms applicable to that service), any other agreement between the Firm and a third party, or any applicable law, regulation, or professional standard.

You are responsible for all activity that occurs under your access to Firm Technology. You shall: (a) keep your login credentials confidential, not share them with any other person, and use multi-factor authentication wherever the Firm makes it available; (b) access Firm Technology only from devices and networks approved by the Firm, and keep approved devices current with Firm-required security updates and protections; (c) comply with the Firm’s information-security, confidentiality, data-handling, and acceptable-use policies as in effect from time to time, including least-privilege access practices and clean-desk and screen-lock requirements; (d) access Client Data only for the Client engagements to which you are assigned and only to the extent necessary to perform the services engaged; and (e) notify the Firm immediately, and in any event within twenty-four (24) hours, upon becoming aware of any unauthorized access to or use of Firm Technology, any lost or stolen device with access to Firm Technology, any compromise of Credentials, or any actual or suspected security incident involving Client Data.

Part II: Terms Applicable to Clients and Client Users

The Firm may make certain Firm Technology, such as client portals, file-exchange tools, and e-signature workflows, available to Client Users in connection with a Client engagement. Subject to this Agreement, the Firm grants each Client User a limited, non-exclusive, non-transferable, revocable right to access and use such Firm Technology solely for the Client’s legitimate business purposes in connection with the Firm’s services. Client Users shall keep their access credentials confidential, use multi-factor authentication where offered, designate only appropriate personnel to hold access, and promptly notify the Firm when a Client User’s access should be revoked (for example, upon that individual’s departure from the Client’s organization).

Certain Firm Technology accesses a Client’s accounts or data on Third-Party Services only after the Client (or a person authorized to act on the Client’s behalf) has completed the applicable authorization flow, such as the Third-Party Service’s standard authorization or consent process (for example, an OAuth consent flow), and consented to the connection as part of an engagement with the Firm. A Client may revoke any such authorization at any time as described in the Firm’s Privacy Policy (available on the Firm’s website at www.all-inaccounting.com) or through the applicable Third-Party Service. Upon revocation or termination of the related engagement, the Firm disables the connection and deletes the stored Credentials for it. The Firm accesses connected accounts and Client Data only to the extent necessary to perform the services the Client has engaged the Firm to provide.

Client Users shall: (a) provide information through Firm Technology that is, to the best of their knowledge, accurate and complete, and remain responsible for the accuracy and completeness of the Client’s own records; (b) use Firm Technology only for lawful purposes connected to the engagement, and not upload or transmit content that is unlawful, infringing, or malicious (including viruses or other harmful code); (c) not attempt to access another client’s data, probe or circumvent security features, or use automated means to scrape or bulk-extract content from Firm Technology; and (d) notify the Firm promptly of any suspected unauthorized access to the Client’s portal account or connected services.

As between the Firm and a Client, Client Data remains the property of that Client. The Firm uses Client Data solely to perform the services engaged, to satisfy its legal and professional obligations, and to operate, secure, and improve Firm Technology, in each case consistent with the engagement agreement, the Firm’s Privacy Policy, and applicable law. Client Data is used to improve Firm Technology only in aggregated or de-identified form that does not identify, and cannot reasonably be used to identify, any Client or individual, and Client tax return information is never used for that purpose. The Firm does not permit Client Data to be used to train, fine-tune, or improve any machine-learning or artificial-intelligence model, whether by the Firm or by any technology provider. The Firm does not sell Client Data and does not disclose Client tax return information except as permitted by the Client’s consent or by law, including Internal Revenue Code Sections 6713 and 7216 where applicable. Upon written request following the conclusion of an engagement, the Firm will return or delete Client Data in its possession, subject to record-retention requirements under applicable law and professional standards; copies retained under those requirements remain protected by Section 10 (Data Protection and Security) and Section 11 (Confidentiality).

Part III: Terms Applicable to All Users

The Firm maintains an information-security program with administrative, technical, and physical safeguards designed to protect Client Data and Firm Technology, consistent with its obligations under applicable law, including the Gramm-Leach-Bliley Act and the FTC Safeguards Rule where applicable, and applicable professional standards. These safeguards include encryption of Client Data in transit and, where supported, at rest; role-based, least-privilege access controls; multi-factor authentication; logging and monitoring of access to Firm Technology; vendor due diligence for Third-Party Services that process Client Data; and periodic review of the security program. If the Firm determines that a security incident has resulted in unauthorized acquisition of unencrypted personal information or Client Data, the Firm will notify affected Clients and, where required by applicable law, affected individuals and regulators, without unreasonable delay, consistent with applicable breach-notification laws, and will cooperate reasonably in the Client’s own response. No security program eliminates all risk, and except as expressly stated in an engagement agreement or required by law, the Firm does not guarantee that security incidents will never occur; this Section describes the program the Firm maintains, not a warranty of uninterrupted security.

All Client Data, and all non-public information concerning Firm Technology itself (including its architecture, Credentials, and security measures), constitute confidential information. Each Authorized User and Client User shall hold such information in strict confidence, use it solely as permitted by this Agreement, and handle it in accordance with the Firm’s engagement agreements with its Clients, the Firm’s professional obligations (including applicable rules of professional conduct governing accountants), and the Firm’s Privacy Policy. Confidentiality obligations survive termination of this Agreement and, for Authorized Users, termination of your relationship with the Firm.

Firm Technology, together with all software, documentation, designs, templates, and other materials associated with it, and all intellectual property rights therein, are and shall remain the sole and exclusive property of the Firm or its licensors. No title to or ownership of Firm Technology is transferred to you under this Agreement. Client Data remains the property of the respective Client as stated in Section 9. All third-party trademarks are the property of their respective owners. No Third-Party Service provider endorses, warrants, or supports Firm Technology. Any suggestions or feedback you provide regarding Firm Technology may be used by the Firm without restriction or obligation to you.

Firm Technology depends on Third-Party Services, which are provided by their respective providers under their own terms and policies. The Firm does not control and is not responsible for Third-Party Services, including their availability, performance, accuracy, security, or any changes their providers may make to them. Your use of Firm Technology in connection with a Third-Party Service must at all times comply with that service’s applicable terms, including any developer, API, or platform terms that apply to connections the Firm maintains with that service.

FIRM TECHNOLOGY IS PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY 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. THE FIRM DOES NOT WARRANT THAT FIRM TECHNOLOGY WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY THIRD-PARTY SERVICE WILL REMAIN AVAILABLE OR UNCHANGED. THIS SECTION DISCLAIMS WARRANTIES REGARDING FIRM TECHNOLOGY ONLY AND DOES NOT DISCLAIM OR MODIFY ANY OBLIGATION THE FIRM OWES A CLIENT UNDER AN ENGAGEMENT AGREEMENT OR APPLICABLE PROFESSIONAL STANDARDS.

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW: (A) THE FIRM SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR RELATING TO FIRM TECHNOLOGY OR THIS AGREEMENT, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES; AND (B) THE FIRM’S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT ARISING OUT OF OR RELATING TO FIRM TECHNOLOGY SHALL NOT EXCEED ONE HUNDRED U.S. DOLLARS (US $100).

Nothing in this Agreement limits or modifies the Firm’s obligations or liability to its Clients under their respective engagement agreements or under applicable professional standards, and nothing in this Agreement limits liability that cannot be limited under applicable law. As between the Firm and a Client, claims relating to the Firm’s professional services are governed by the applicable engagement agreement, not by this Section.

To the extent permitted by applicable law, you shall indemnify and hold harmless the Firm and its members, officers, and employees from and against any losses, damages, liabilities, and expenses (including reasonable attorneys’ fees) arising out of or relating to your unauthorized use of Firm Technology, your breach of this Agreement, or your violation of applicable law, in each case except to the extent caused by the Firm’s own conduct. This Section does not apply to conduct within the ordinary scope of an Authorized User’s employment with the Firm where such indemnification is prohibited by law, and it does not modify any allocation of responsibility in a Client engagement agreement.

This Agreement is effective from your first access to any Firm Technology and continues until terminated. The Firm may suspend or terminate your access to Firm Technology, or terminate this Agreement, at any time, with or without cause and with or without notice, including where the Firm reasonably believes suspension is necessary to protect Client Data or the security of Firm Technology. An Authorized User’s license terminates automatically upon the end of employment or engagement with the Firm or upon breach of this Agreement; a Client User’s access terminates upon conclusion of the related Client engagement, upon the Client’s request, or upon breach of this Agreement.

Upon termination of a Client engagement or revocation of a Client’s authorization, Firm Technology’s access to that Client’s connected accounts is disabled and stored Credentials for those connections are deleted, and Client Data is handled as described in Section 9. Upon any termination of this Agreement, you shall immediately cease all use of Firm Technology. Sections 4, 5(e), 8, 9, 10, 11, 12, 13, and 14 through 20 survive any termination of this Agreement.

You shall use Firm Technology in compliance with all applicable federal, state, and local laws and regulations, including those governing data privacy and security (such as the Gramm-Leach-Bliley Act and applicable state data-protection and breach-notification laws) and, where applicable, the confidentiality of tax return information under Internal Revenue Code Sections 6713 and 7216, and with all professional standards applicable to the Firm’s practice, including applicable rules of the AICPA and state boards of accountancy.

(a) Governing Law; Venue. This Agreement is governed by the laws of the State of Missouri, without regard to its conflict-of-laws principles. The state and federal courts located in the State of Missouri shall have exclusive jurisdiction over any dispute arising out of or relating to this Agreement, and each party consents to the personal jurisdiction of such courts.

(b) Amendments. The Firm may amend this Agreement from time to time by providing notice to Authorized Users and Client Users or by posting the amended Agreement; for material changes, the Firm will provide reasonable advance notice (for example, by email or through Firm Technology) before the amended Agreement takes effect. Your continued use of Firm Technology after an amendment becomes effective constitutes acceptance of the amended Agreement.

(c) Entire Agreement. This Agreement, together with the Firm’s policies referenced in it, constitutes the entire agreement between you and the Firm regarding access to and use of Firm Technology and supersedes all prior or contemporaneous understandings on that subject, including all prior end user license agreements for any component of Firm Technology. In the event of a conflict between this Agreement and a Client engagement agreement, the engagement agreement governs as between the Firm and the Client.

(d) Severability; Waiver. If any provision of this Agreement is held unenforceable, that provision will be enforced to the maximum extent permissible and the remaining provisions will remain in full force. No failure or delay by the Firm in exercising any right is a waiver of that right.

(e) Assignment. You may not assign or transfer this Agreement or any rights under it. The Firm may assign this Agreement without restriction.

(f) No Third-Party Beneficiaries. This Agreement does not confer any rights on any third party. No provider of a Third-Party Service is a party to, or has any obligations under, this Agreement.
