Is Deleix Invoice Maker completely free?
Yes. Deleix Invoice Maker is completely free to use. There are no monthly subscriptions, hidden fees, watermarks, or user account sign-ups required.
Where is my invoice data stored?
All invoice drafts are stored exclusively in your web browser's local storage (under the dim.* key namespace). Your financial data never leaves your device and is never uploaded to any remote server.
How does the calculation engine avoid rounding errors?
Unlike typical web applications that use JavaScript IEEE 754 floating-point numbers, Deleix Invoice Maker uses an exact BigInt fixed-point engine scaled to 1,000,000 units. Subtotals, tax component groupings, pro-rata invoice discounts, and deposits balance to the exact cent every time.
Can I generate multi-page invoices with many line items?
Yes. The built-in PDF generator automatically measures page height, prevents line items from breaking across pages, repeats the table headers on subsequent pages, and groups the summary totals together on the final page.
Can I print invoices directly without downloading a PDF?
Yes. Clicking the “Print” button triggers your browser's native print dialogue using our custom print stylesheet. All navigation, buttons, and form inputs are automatically hidden, leaving only the clean invoice document formatted for paper or native Print to PDF.
