Nobody falls in love with a standard

Until 27 countries need to talk to each other. Why boring standards like UBL and EN 16931 quietly make digital tax possible.

Until 27 countries need to talk to each other.

World Standards Day (14 October) is probably not the biggest date in your social calendar. But in digital tax, standards quietly do a ridiculous amount of work.

Structured invoice models. Common semantic definitions. UBL. EN 16931. Network specifications.

Nobody puts them on a billboard. Good. Their job is to make different systems understand the same transaction, and that is what makes scale possible.

Why we like boring standards

They allow us to focus on the interesting part:

  • getting the Oracle data right
  • applying the correct indirect tax logic
  • reconciling the outcome
  • supporting multiple countries without reinventing everything

A standard is successful when nobody notices it. Until it is missing. Then everybody notices.

Let's talk about Tax baby.
