Concepts

This section explains what are the main concepts in Erply, how they fit together, and what does Erply's data model look like.

The documentation of API calls generally only tells what is the required input and expected output, and what do the individual fields mean. At the same time, the documentation might not give clear answers to more general questions, such as:

  • How can a product catalog be organized? Can a product belong to multiple groups?
  • What exactly is required to set up taxes?
  • What does a "location" mean? Do I need to have locations?

This is hopefully explained in the pages below.
