I've seen some solid concepts at this stage using circles and arrows which both make sense for a supply company. I'm not sure if a chain of some kind makes sense (ie Supply chain). My limited design talents only see chains in very masculine of designs, which we do not want, but that's why we come to you. None of these are requirements, but rather ideas we've seen and liked.
Remember, we're partners with our clients. We're a supply company. We don't want them to buy something from us once. We want clients to come to us to resupply them every month.
Thank you all.
