Hello, I have worked on the similar projects in the past. Could you please tell me some more information about your website the platform which you are using if you want the portal to update those quantity on your website as well regarding your suppliers website at the providing any API or do we need to scrap their website. I have been doing this similar work for a New Zealand based company, but they have API from their suppliers, which makes things easier because we need to do it on every hour.
Best,
