What should I use to create invoice PDFs from structured data?

To create invoice PDFs from structured data, the best choice depends on how much control, scale, and development effort you want.

Common options

1. HTML/CSS + PDF renderer

Best for most apps

• Generate invoice data into an HTML template
• Render to PDF using:
  • Puppeteer/Playwright (Node.js)
  • wkhtmltopdf
  • WeasyPrint (Python)

Pros

• Easy to design with familiar HTML/CSS
• Great for invoices and other document layouts
• Easy to keep templates maintainable

Cons

• Some CSS/PDF quirks
• Pixel-perfect print layout may take tuning

Good if: you already have a web app or want flexible, attractive invoices.

2. PDF libraries that draw directly on the page

Examples:

• PDFKit (Node.js)
• ReportLab (Python)
• iText / Apache PDFBox (Java)

Pros

• Precise control over layout
• No browser rendering needed
• Good for programmatic generation at scale

Cons

• More work to create nice-looking documents
• Layout code can get verbose

Good if: you want full control or need to generate lots of highly structured PDFs.

3. Document templating tools

Examples:

• Prawn (Ruby)
• JasperReports
• Microsoft Word/LibreOffice templates exported to PDF

Pros

• Good for business documents
• Easier for non-developers to edit templates in some cases

Cons

• Tooling can be heavier
• Less flexible than HTML templates in many cases

My recommendation

For invoice PDFs from structured data, I’d usually recommend:

• HTML/CSS template + Playwright/Puppeteer if you’re building a web-based system
• ReportLab or PDFKit if you need direct PDF generation without a browser

Practical choice by language

• JavaScript/TypeScript: Playwright or Puppeteer
• Python: WeasyPrint or ReportLab
• Java: iText, PDFBox, or JasperReports
• Ruby: Prawn
• Go: Go PDF libraries, though HTML-to-PDF is often simpler via external tools

If you want, I can suggest the best option based on your stack and give a minimal example.
