Frequently Asked Questions
Are my client names or financial records saved or sent to any server?

No. The invoice engine executes 100% in your local browser sandbox. Your business information, client details, and financial figures are never transmitted to any third-party server.

Can I use different currencies and tax rates?

Yes. You can customize the currency symbol ($, €, £, ₹, ¥, etc.), adjust tax and discount percentages, and add personalized payment terms.

How do I save invoices for future billing?

Your invoice data is automatically preserved in your browser's local storage so you can return to update items or re-download your PDF anytime.
