I’d start from the premise of aiming to sell more things to more people. In practice this can result in a range of actions. One of those can be a cooperative sales motion and one could be to expand your portfolio, so that your clients can source multiple products and services from you. If they’ve already bought, they’re likely to buy from you again. Cooperative selling is where you’re partnering with another similar business with complementary offerings and you simply look to sell to each others’ client. I’m seeing a marked increase in this latter approach.
If you a bereft of ideas or simply feel are stuck – drop me a line. Always happy to help
