Online store that update prices automatically from provider

We already have an online store: [login to view URL] and we sell cctv related products via our web, on amazon, on [login to view URL], on facebook, and in our physicall store. Our two main issues is that with have more than 300 different products and our provider prices changes constantly so the task of updating prices manually takes away a lot of time. Also our bussiness model is to have some inventory but we also publish some products in our online store that we don’t have so when the client buys that product we go to our provieder and we buy it so we also need to constantly check the inventory from our provieders to ensure that we are selling products that we can get. In this moment we have a POS system for our sales in our physical store. That system is not linked with our online store so if we need to update a price or a product we need to update in both places We need a solution that: - Gets prices and inventory automatically from our providers. We mainly have 2 providers and both have their catalog on their webpages: [login to view URL] and www.syscom.mx. As far as we know they don’t have APIs to get their inventory information. It will have to be done with automation tools such as selenium - Automatically update prices and inventory in our online store - Automatically update product pictures and description from provider - The online store will be a new one because the current one only have options to update products manually. The new online store can be on wordpress with woocomerce or similar. We already have a domain: [login to view URL] - Automatically publish new products. - Product list are downloaded to a csv file so we can update prices in our POS system
