A strategic alliance is when you and another business go into a loose partnership to help each other make extra profits.
For example, a tree surgeon may refer work to a gardener, and vice versa. They may give each other 10% of the price tag of any referred work. Suddenly, each has a ‘scout’ working for them. The number of suppliers the tree surgeon may do this with is unlimited, although it’s probably wise to work with only one of each type of business.
