Be able to calculate sales commissions per user. Currently, the best way to calculate commissions is based on tags. For example, by adding a tag with the name of the commercial to each of your contacts, this will allow that when generating any document to that contact, it will be generated with the commercial's tag. If you want to change it, you could also do it when creating the document. Then, you can filter by these tags, which are the names of the commercials, to know the sales of each of them.
