Hey Sergio,
Thanks for reaching out!
The answer to all of your queries here is “Yes”, with one exception: the specific “running bib numbers” features you mention.
Our plugins do not offer any sort of way for bib numbers to be auto-generated, if that’s what you were implying. There is no system for that within our plugins, nor another system similar to that that could be used in its stead.
If you can elaborate a bit more on what you need in regards to bib numbers specifically, I may be able to provide a more specific bit of insight on that.
But in general, like I said, for everything else you mention Event Tickets Plus can do that.
What you call “custom fields” here, Event Tickets Plus calls “additional information.” Same thing! You can add custom input fields for tickets that allow for the entry, collection, and export of all sorts of data.
Check out this knowledgebase for a more in-depth look at these features—the “Additional Attendee Information” section should be of particular interest: https://theeventscalendar.com/knowledgebase/managing-your-orders-and-attendees/
Cheers,
George
