The billomat[API] is an open data and pro­gramming inter­face which enab­les you to access the data in your Bil­lo­mat account via HTTP and XML/JSON. With this, online and desk­top app­li­ca­ti­ons can be crea­ted which seam­lessly inte­grate into your Bil­lo­mat account.

Here are a few ideas for poten­tial app­li­ca­ti­ons of the API:

  • Your own importing tools (CSV data, ERP-, WaWi– und CRM-systems, …)
  • Auto­ma­tic invoi­cing and bil­ling of tran­sac­tions from online shops
  • Indi­vi­dual eva­lua­ti­ons and data analyses
  • Data trans­fer to accoun­tants and tax consultants
  • Lin­king to online pay­ment systems
  • Wid­gets for iGoogle, net­vi­bes, OSX Dash­board, Win­dows 7 Gadgets, …
  • Native cli­ents for mobile plat­forms (iPhone, Android, Sym­bian, Win­dows Mobile)

Or quite dif­fe­rent mas­h­ups which we can’t even ima­gine yet. It’s up to you to test out the poten­tial of the billomat[API] to its limits, and to extend the boun­da­ries of the possible!

Whe­ther you use the billomat[API] just for your own per­so­nal requi­re­ments and deve­lop a link to inter­nal sys­tems, or whe­ther you want to make it publi­cly avail­able – the deci­sion is yours alone. You can even offer your con­nec­tion on a char­ging basis (even if we’re plea­sed about con­nec­tions avail­able free of charge, of course). It’s ent­i­rely up to you!

Bene­fit from the Bil­lo­mat Ecosystem

If you make your API app­li­ca­tion publi­cly avail­able to third par­ties, you can bene­fit from our ecosystem.

The several thousand users of Bil­lo­mat at home and abroad rep­re­sent a large and attrac­tive tar­get group. Addi­tio­nally, Bil­lo­mat is one of the best-known web-based invoi­cing ser­vices in the German-speaking coun­tries, with a strong pre­sence in well-known online and off­line media

You can pro­fit too from Billomat’s suc­cess, and create bril­li­ant app­li­ca­ti­ons with the billomat[API] that the world’s been wait­ing for!
