The best part of vendor portals, which I found useful was that all my vendors are in one place i can easily access them from anywhere at any time without being present physically with those companies who sell me products for production or supply chain management. It's still quite buggy when you have more than 50-60 items but it gets better as soon as new features get added. With this system we can keep track of our inventory levels across multiple locations. We also make sure orders come through only once so there is no risk of double ordering etc.. Vendor portal has made my life easier, I used to manage all vendors in one place, now I can see all vendors information in one place, it's very helpful for me to keep track of my vendors. Nothing so far. It is very good and highly recommended, we recommend vendor portal to everyone who want to take control of their business. We are managing our vendor with Vendor portal. It really helped us manage our vendors and we can get more information about them from any where at anytime.
