# Research: Finance

We track the rules and deadlines that change how a business invoices and gets paid.

## What we ask

- Tax and invoicing rules, as the authorities publish them.
- What changes, for whom, and when.
- The instruments themselves, with the date of every check.

## What we do with it

A tracker says plainly what SalexHub does and does not do under each rule. Nothing in it is tax or legal advice.
