Looking for modules useful for multi stock and drop shipping

[YoannFR]

Hello folks,

We are building an online store with multiple drop shipping suppliers in addition to our own stock.

The suppliers we work with already provide their PrestaShop plugin to sync their catalog and stock. So far we included one and planing for the second, which ask questions of course. 
 

This lead us to looking for advice for the following needs, and we talk for thousands of references per supplier, so automation and robustness is needed.

 

We need to have a way to manage shipment fees per supplier. 

We need to have different stock per supplier, and eventually some product in more than one supplier. 

We need multiple supply price for product in more than one supplier. 

We need sub basket in the shipment fees calculation, based on in which stock the product is. 

And if some product are in more than one stock, a preference logic to group products as much as possible. 
 

So far that’s our main needs and limitations seen with prestashop. 
 

We tired to look at the marketplace but their is way to many option and no trials. 
 

We already have an issue with a template we bought that is not working as expected and can’t get a refund for it. 
 

So even if we are OK to pay for the modules we need, we are not OK to pay for module that does not suite the needs and sellers that deny our refund request after few hours or days of test.
 

So we are here for advice on module to add here that could fit our needs.

 

Thanks!
