KSeF Invoice Prefill

About

KSeF Invoice Prefill helps users prepare VAT invoices in the Polish KSeF taxpayer application faster by saving reusable invoice templates and applying them to the KSeF invoice wizard.

The extension lets users create and manage templates for seller data, buyer data, invoice details, invoice line items, prices, VAT rates, and selected optional invoice fields. A user can fill the template directly in the extension, apply it to the current KSeF step, or save values from the current KSeF step back into the selected template.

Key features:
- Save reusable invoice templates locally in Chrome.
- Prefill seller and buyer details, including NIP, name, country, address, and related fields.
- Prefill invoice details such as invoice number, issue date, issue place, currency, price mode, line items, quantity, unit, net price, net value, and VAT rate.
- Apply a template step by step in the KSeF invoice wizard.
- Save the currently filled KSeF step into a template for future use.
- Optional auto-apply mode when moving between invoice wizard steps.
- Interface available in English, Russian, and Polish.

The extension stores template data locally in the browser using Chrome storage. It does not send invoice data, company data, NIP numbers, browsing history, or template content to the developer or to third-party services.
