About ERP Reference: how the reference data is made

About ERP Reference

Sourced reference data for the people who set up and run ERP systems.

How the data is made

Every value comes from a source that was actually read: official government and EU publications, standards bodies and vendor documentation first. Secondary sources are used only where no primary source is available, and are labelled as such.
Each record shows its source and the date it was last checked.
Where something could not be verified, the page says "unknown" instead of filling the gap with a typical value.
When a value changes, the change is dated.

It is not legal, tax or financial advice. Check the linked source, and an adviser where it matters, before acting.
It does not sell rankings or placements, and it shows downsides and gaps alongside the data.
It does not set cookies or track visitors across sites.

If a value here differs from the source linked next to it, the source is authoritative.
