This one caught me off guard.
The normal sales process for an Atlassian plugin is to have a 30 to 90 day evaluation period, after which a company might or might not decide to buy a commercial license. This morning however, a sales transaction appeared in my Atlassian vendor page from a company I did not see before. They apparently decided to proceed with buying a commercial license without having a trail first, or the trial at least did not show up in my records.
Needless to say this was a very pleasant surprise and the first real validation.
