Hi, we have been having lots of issues of support and functionality with Etail, any idea what extension will be a better option?
Happy to help try and point you in the right direction but need a bit more information in order to do so.
We don't support Magento 2 at the moment (although it's in development) so we're almost certainly not a fit at the moment.
Which marketplaces are you selling on?
Are you looking for a solution from which to manage all sales channels including Magento or are you looking to run marketplaces channels from Magento?
