Frequently asked questions
The most common questions about Smart Invoice Generator.
Getting started
Is there a setup wizard for new users?
Yes. The first time you open Settings & Design, a guided 3-step tour walks you through your logo, company information, and date/number format — see the Getting Started guide for the full walkthrough.
Limits & billing
When does my monthly invoice limit reset?
Your billing cycle resets on your subscription anniversary (the date you subscribed). On the Free plan, it resets on the 1st of each calendar month.
What happens once I hit my limit?
On the Free plan, you can't generate more invoices until the next reset on the 1st. On Basic, the same applies until your next billing date. The Business plan has no limit at all.
Design & language
Can I customize the design of my invoices?
Yes. Logo, colors, font sizes, layout, company data, payment terms, footer text and an optional "Paid" stamp can all be configured under Settings & Design — available on every plan. See the Settings & Design module for the full list.
Does the app support multi-language stores?
Yes. Invoices are available in English, German, French, Spanish, Italian, Dutch and Portuguese. You can also add your own translations or a fully custom language via JSON import — see Languages.
Sending & automation
How do I get invoices to my customers automatically?
On Basic and Business, email sending can trigger automatically on payment. On the Free plan, sending is manual — either way, it's sent as a PDF attachment using a template you can fully customize.
Can invoices be pushed automatically into my accounting system?
Yes — SFTP Server Export (Basic and Business) automatically uploads invoices to your own server, and a CSV export with up to 25 customizable fields is also available.
Privacy & security
Is the app GDPR compliant?
Yes. Smart Invoice Generator only processes order and customer data to create documents, stores minimal metadata long-term (like your design and email settings), and supports all GDPR webhooks required by Shopify. See the app's Privacy Policy for details.
What happens to my data if I uninstall the app?
Your configuration is kept for 30 days in case of an accidental uninstall. After that, everything is deleted automatically and permanently. You can also request immediate deletion in the app or by emailing info@erostech.de.
Support
Where can I get support?
Through "Contact Support" inside the app, or via the contact form on our website. Basic and Business customers get priority email support.
