It depends on what platform your supplier is using. We specialize in customizing data flows for client needs so you are not limited by some platforms that give you specific fields or data flows that you have to use.
Our product information management platform allows you to integrate your supplier data, map to your requirements and then push to your Shopify store. We split product data and inventory data flows so you can enrich and add any missing data to your products before pushing them to Shopify.
We have a number of integrations from complex ERP's like SAP to other ecommerce systems so we may have what you are after but if not we build and customize as needed.
Just shoot me an email with details to tom@ channelup.com.au and I can take a look for you and give you some options.
