Every SaaS product and e-commerce store eventually needs to generate invoice PDFs. Most teams start with a Word template, Canva, or a drag-and-drop builder, and that works fine for five invoices a month. Once you hit hundreds or thousands, you need something that runs without human input.

This guide covers three ways to generate invoice PDFs with an HTML to PDF API: raw HTML templates, Handlebars-based templates with dynamic data, and AI-generated templates. Complete with working code in Node.js and Python that you can run.

Most n8n workflows eventually need to produce documents – invoices after purchases, scheduled reports, certificates for course completions. Setting up PDF generation inside n8n usually means dealing with HTML rendering quirks or managing headless browser instances. PDFBolt's API plugs directly into n8n's HTTP Request node, so you send template data and get back a finished PDF. No browser setup, no rendering config – just an API call.
