I hate accounting, especially invoicing. It's a repetitive, mind-boggling task, that steals away my energy; thus should be handled by a machine. Believe me, I would give my pinky toe if I never ever had to do it again. At most I just want to scribble a few notes and be done with it. Maybe Tyler King hat the same thoughts while he created Markdown Invoice to solve the problem. It turns Markdown invoices into HTML or PDF. Of course his tool is totally rad, so I borrowed it and adjusted it to my own needs. This somehow grew out of my hand and I added a bunch of features and gave it a new name - karban. Karban is a hacker-friendly, static invoice generator. It's kinda like Jekyll, but for invoices.


Simple. Put your invoices into the invoices/ directory. See for an example invoice in Markdown and its PDF output.

Example run:

./karban --invoice="invoices/2424-11-04-xxx" --output=pdf --layout="layouts/unicorns.html"
Compiling invoice "invoices/2424-11-04-xxx"...
PDF saved to: invoices/2424-11-04-xxx.pdf


  • Fancy HTML/CSS invoice layouts (with separate headers and footers) using Twig
  • PDF output
  • Meta data using YAML FrontMatter
  • Multiple layouts
  • Keep a plain text version of your invoices. Text files are awesome.
  • Completely adaptable to your own workflow
./karban --help
 karban [-f|--format[="..."]] [-o|--output[="..."]] [-l|--layout[="..."]] [invoice]

At the moment you have to fiddle around with the page breaks when things go awry. That's a known issue caused by wkhtmltopdf. Yeah, it sucks; the only alternative might be to look for an alternative or wait for a proper fix since all the available hacks are messy. For the time being, you can use <div class="pagebreak"></div> anywhere in your markdown invoice to force a page break.
