by HoopoeGem · offline · one‑time license
Create professional invoices, track payments, monitor overdue balances, and export PDFs —
all from a simple offline app with no monthly fees.
Free: full invoice creation. PDF export unlocks with paid license.
No subscription required.
Your purchase includes a license for the current major version of InvoiceApp.
You may continue using the version you purchased indefinitely.
Future major releases may be offered as separate paid upgrades.
After purchase, you'll receive a license key via email. Open InvoiceApp, go to the License tab, enter your email and license key, then click Activate License. PDF export unlocks immediately.
Your license key works on up to 2 personal devices (e.g., desktop + laptop). If you need it on more devices, contact support to deactivate one and reactivate another.
InvoiceApp stores your invoices and settings in your browser's local storage. Clearing your browser cache will permanently delete all your invoice data. Always use the Export Backup feature in the Settings tab to keep your data safe. We cannot recover lost data.
No — after the initial load, it works entirely offline in your browser. You only need internet to activate your license (once) and to access the app initially.
Due to the digital nature of the product, refunds are generally not offered after license delivery. If you experience a technical issue, please contact support and we will work with you to resolve it.
Email us at hoopoegem@gmail.com with your purchase email, and we'll resend your key.
Your license covers the version you purchased.
Minor updates and bug fixes may be included at our discretion.
Future major releases (such as Version 2.0 or later) may require a separate purchase.
InvoiceApp is designed to work locally in your browser.
The version you purchased will continue to function on supported browsers
even if future development or support ends.
We strongly recommend exporting backups regularly.
