Hi,
1 - A vendor is an entity which can have several linked account.
There is the vendor administrator but you can also configure other Joomla account to be manager of the vendor (and give them different rights).
And HikaMarket Multi-vendor allow you to create an unlimited number of vendors in your store (when HikaMarket front-editon just allow one single vendor).
2 - You should be able to configure your taxes in HikaShop.
You can also use plugins like "Taxcloud" or "Avalara" to have dynamic management of the taxes.
