Over time there have been heaps of requests for improved reporting.
Back in January @cs-cart stated
We do have plans to revise the accounting in Multi-Vendor, but there is no exact date for when there will be news on this topic. An announcement will be made when there is news worthy of such an announcement.
This thread is for anyone (not just developers) to post SQL queries and a one paragraph description that generates desired information … this will mean that cs-cart (or other developers) can build an add-on that generates the reports the community want/need … and in the meantime people that don’t have the knowledge of SQL/cs-cart structure to generate them themselves can get some reports (… for those so challenged actually running a SQL query is simple, google running SQL in [myphp admin - if you have cpanel]).
