by HoopoeGem · offline · one‑time license
Professional invoicing that works offline. Create, send, and manage invoices with ease.
Free version: full invoice creation. PDF export unlocks with paid license.
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.
Each license key is valid for one device. If you need to use it on multiple computers, you can purchase additional licenses or contact support for deactivation/reactivation.
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.
All sales are final. Because you receive a permanent, non-transferable license key immediately after purchase, we do not offer refunds. If you encounter technical issues, contact support and we will help resolve them.
Email us at hoopoegem@gmail.com with your purchase email, and we'll resend your key.
