Effective date: July 2, 2026
These Terms of Service ("Terms") govern the use of FlatInvoice ("the App"), a Shopify application operated by Stelar Digital LLC ("we", "us"). By installing or using the App you agree to these Terms.
FlatInvoice generates PDF invoices and packing slips for orders in your Shopify store. Documents are rendered on demand from your store's order data and delivered to you for download or printing.
The App is offered as a subscription at $9 USD per month, with a 7-day free trial. All billing is handled through Shopify Billing and appears on your regular Shopify invoice. No payment details are collected by us directly.
You may cancel at any time by uninstalling the App from your Shopify store. Billing stops automatically upon uninstall through Shopify Billing; no separate cancellation step is required.
You agree to use the App only for lawful purposes and in connection with a store you own or are authorized to operate. You may not attempt to interfere with, reverse engineer, or disrupt the operation of the App.
The App is provided "as is" and "as available", without warranties of any kind, whether express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the App will be uninterrupted, error-free, or that generated documents will meet every jurisdiction's invoicing requirements. You are responsible for verifying that documents produced by the App satisfy your legal and tax obligations.
To the maximum extent permitted by law, Stelar Digital LLC shall not be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, or business opportunity, arising out of or related to your use of the App. Our total aggregate liability for any claim arising from these Terms or the App shall not exceed the amount you paid us in the three (3) months preceding the claim.
We may modify the App or these Terms at any time. Continued use of the App after changes take effect constitutes acceptance of the revised Terms.
These Terms are governed by the laws of the United States, without regard to conflict-of-law principles.
