Welcome to the OSPOS Guide

Open Source Point of Sale (OSPOS) is free POS software for retailers.  As the name suggests, it's also open source.  This means you can use the software and change it for free.

OSPOS has the following features:

  • Point of Sale (POS)
  • Inventory Control
  • Customer Relationship Management (CRM)
  • Reporting
  • And More!

Please visit our tour for more information about these features.

We recommend Digital Ocean to host OSPOS online.  If you sign up through our link, you'll get a $10 credit with Digital Ocean and we'll install OSPOS for free.

You can also read our Installation Guide that walks you through installing the software on your local Windows machine.

Note: We have many guides and tips about OSPOS. Most of the screenshots need to be changed, though, as OSPOS has updated its user interface.

We now have a development page. Here we discuss how to get started with developing for OSPOS or how to hire us if you want to do that.
