Terms and Conditions
Effective date: April 18, 2026
This End-User License Agreement ("Agreement") is a legal agreement between you ("User," "you," or "your") and APStack, Inc. ("APStack," "we," "our," or "us") governing your use of the APStack accounts payable automation platform and all related services, features, and content (collectively, the "Service"). By creating an account or using the Service you agree to be bound by this Agreement. If you do not agree, do not use the Service.
1. License Grant
Subject to your compliance with this Agreement, APStack grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Service solely for your internal business purposes. This license does not include the right to sublicense, resell, or otherwise make the Service available to third parties.
2. Description of the Service
APStack provides an AI-powered accounts payable automation platform that allows users to:
- Upload invoice documents for automated data extraction
- Review, correct, and approve extracted invoice data
- Connect to QuickBooks Online and post approved invoices directly
- Send invoices, receipts, statements, and AP documents to APStack by SMS/MMS when text intake is enabled
- Monitor invoice status, confidence scores, and AP activity
- Detect potential duplicate invoices
3. Account Registration
You must create an account to use the Service. You agree to provide accurate, current, and complete information and to keep your account credentials confidential. You are responsible for all activity that occurs under your account. Notify us immediately at
info@apstack.ai if you suspect unauthorized access.
4. QuickBooks Integration
The Service integrates with Intuit QuickBooks Online through Intuit's authorized OAuth 2.0 API. By connecting your QuickBooks account you authorize APStack to read and write accounting data (including bills and vendor records) on your behalf, solely as directed by your actions within the Service. APStack is not affiliated with or endorsed by Intuit Inc. Your use of QuickBooks is also governed by Intuit's own terms of service and privacy policies. APStack is not responsible for any changes Intuit makes to its API, pricing, or availability.
5. APStack SMS/MMS Terms
By opting in to APStack SMS/MMS, you agree to receive transactional text and multimedia messages from APStack related to your APStack workspace. Messages may include document intake confirmations, receipt/invoice/bill/statement processing updates, review requests, workspace alerts, account activity messages, and support-related responses.
You opt in by logging into your APStack account, going to Settings / Text Intake, entering your mobile phone number, and checking an optional, unchecked SMS/MMS consent checkbox. Consent to receive SMS/MMS messages is optional and is not required to create an account or use APStack.
Message frequency varies based on your APStack activity. Message and data rates may apply. Reply HELP for help or STOP to opt out at any time. For help, reply HELP or contact us at info@apstack.ai. Carriers are not liable for delayed or undelivered messages.
APStack does not use this SMS/MMS program to send marketing, promotional, lead generation, or third-party advertising messages.
6. Your Data and Content
You retain full ownership of the invoice documents and financial data you upload to the Service ("Your Content"). By uploading content you grant APStack a limited license to process, store, and display that content solely as necessary to provide the Service. We will not share Your Content with third parties except as described in our Privacy Policy or as required by law.
7. Acceptable Use
You agree not to:
- Use the Service for any unlawful purpose or in violation of any regulations
- Upload fraudulent, forged, or intentionally misleading documents
- Attempt to reverse-engineer, decompile, or extract source code from the Service
- Interfere with or disrupt the integrity or performance of the Service
- Use automated means to access the Service in a manner that exceeds normal usage
- Attempt to gain unauthorized access to any portion of the Service or its systems
8. No Financial or Accounting Advice
The Service automates data extraction and facilitates posting to accounting software. APStack does not provide financial, accounting, tax, or legal advice. Confidence scores and extracted data are provided as a tool to assist your review — they do not constitute a guarantee of accuracy. You are solely responsible for verifying the accuracy of invoice data before approving or posting it to your accounting system.
9. Intellectual Property
The Service, including its software, design, trademarks, and all content produced by APStack (excluding Your Content), is owned by APStack and protected by applicable intellectual property laws. Nothing in this Agreement transfers any ownership rights to you.
10. Fees and Payment
Access to the Service may require payment of subscription fees as described on our pricing page. All fees are non-refundable except as required by law or as expressly stated in a separate written agreement. APStack reserves the right to change pricing with 30 days' notice.
11. Termination
Either party may terminate this Agreement at any time. APStack may suspend or terminate your access immediately if you breach this Agreement. Upon termination you must cease all use of the Service. Sections 8, 9, 12, and 13 survive termination.
12. Disclaimer of Warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. APSTACK DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT EXTRACTED DATA WILL BE PERFECTLY ACCURATE.
13. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, APSTACK SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS, ARISING FROM YOUR USE OF THE SERVICE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. APSTACK'S TOTAL LIABILITY SHALL NOT EXCEED THE GREATER OF (A) THE FEES YOU PAID IN THE 12 MONTHS PRECEDING THE CLAIM OR (B) $100.
14. Governing Law
This Agreement is governed by the laws of the State of Delaware, without regard to conflict of law principles. Any disputes shall be resolved in the state or federal courts located in Delaware, and you consent to personal jurisdiction in those courts.
