Terms of Service
1. Service Provider
Avantium is provided by Avantium AI LLC (EIN 98-1967053 · Delaware File #10743587), a Delaware limited liability company with principal address at 16192 Coastal Highway, Lewes, DE 19958, United States (“Avantium,” “we,” “us,” or “our”). By creating an account or using our web or mobile applications, you agree to these Terms of Service.
2. Eligibility & Business Use
Avantium is a B2B cloud software-as-a-service (SaaS) platform designed for commercial contractors, home service businesses, and field service professionals. To create an account, you must be at least 18 years old and have authority to bind yourself or the business entity you represent.
3. Account Access & Team Permissions
You sign in using your email address and a one-time verification code. You are responsible for safeguarding access to your email account and for all activity conducted under your business account. If you invite employees, technicians, or office staff, you control each user's role and permissions within the platform.
4. Service Communications
When you register, you agree that we may contact you via email, WhatsApp, or phone to help you get started, deliver account and billing notifications, and share product updates. You can opt out of promotional messages at any time via the unsubscribe link in any email or by writing to support@avantium.app. Essential transactional and security notices continue while your account remains active.
5. Subscription Plans, Pricing & Billing
- 14-Day Free Trial. New accounts receive a 14-day free trial with full platform features and no credit card required. At the end of the trial, you may subscribe to a paid plan; if you choose not to subscribe, you will not be able to create new jobs, but your existing customers, estimates, and invoices remain accessible for export.
- Subscription Plans & Currency. Current plan tiers (Solo Pro from $22/mo billed every 2 years or $29/mo monthly, Premium from $29/mo, Projects from $44/mo, Team, and Scale at $149/mo for up to 10 users) are published on our Pricing page. For United States and international customers, subscriptions are billed in United States Dollars ($ USD) (or EUR where selected at checkout). You receive an itemized invoice/receipt for every payment.
- Billing Cycle & Auto-Renewal. You may choose monthly, annual, or two-year billing. Subscriptions are billed in advance and automatically renew for the same term unless canceled prior to the renewal date.
- No Long-Term Lock-In & Cancellation. You may cancel your subscription at any time from your account settings or by emailing support@avantium.app. Cancellation takes effect at the end of the current paid billing period. Prepaid fees are non-refundable except where required by applicable law.
- Plan Changes. When upgrading plans or adding seats, you pay only the prorated difference for the remainder of the billing cycle; downgrades take effect at the next renewal.
- Payment Processing. Subscription payments are processed securely via Stripe. If a renewal charge fails and remains unresolved after reasonable notice, your account may be paused without deleting your data.
6. Online Payments from Your Customers
If you enable online customer payments in the client portal, your customers pay you directly through your connected Stripe account. Funds flow from your customer to your Stripe account; Avantium does not hold or custody your customer funds. Stripe's own merchant terms and processing fees apply.
7. Ownership of Your Business Data
You retain full ownership of all customer records, estimates, work orders, photos, and invoices you upload or create in Avantium. You grant us a limited license solely to host, back up, and process that content to provide the service to you.
8. Data Processing Agreement (Service Provider / Processor Terms)
With respect to personal data of your customers and employees that you store in Avantium, we act as your Data Processor / Service Provider and commit to:
- Process such data solely to deliver the Avantium service in accordance with your instructions.
- Maintain strict confidentiality and industry-standard encryption in transit and at rest, with daily encrypted backups.
- Never sell, rent, or use your customer data for advertising or for training artificial intelligence models.
- Use only the vetted subprocessors listed in our Privacy Policy.
- Notify you without undue delay in the event of a confirmed security breach affecting your account data.
- Allow you to export your estimates, invoices, and records at any time, and delete your data upon account termination.

10. AI-Assisted Features
Avantium includes optional AI tools to draft estimates from voice or text and extract fields from vendor receipts. AI outputs are drafts provided for your review and approval before sending to customers; you remain responsible for verifying all final figures, descriptions, and taxes.
11. Invoicing & Tax Responsibility
Avantium helps you generate professional estimates, work orders, and invoices, and export quarterly accounting summaries for your CPA or bookkeeper. You remain responsible for configuring the appropriate tax rates and complying with applicable federal, state, and local tax regulations.
12. Limitation of Liability

To the maximum extent permitted by applicable law, Avantium AI LLC shall not be liable for indirect, incidental, consequential, or lost-profit damages, and our aggregate liability arising out of or relating to the service shall not exceed the total subscription fees paid by you to Avantium AI LLC in the twelve (12) months preceding the claim.
