How many vendors does your company utilize over the course of a year? Depending on what type of business you have, that number could vary significantly. You may have one "go-to" provider for some items, but multiple suppliers for other items or services you use on a day-to-day basis.
While your company may have fewer suppliers than your favorite coffee shop down the street, if you look at THEIR vendor list, you may find there's a good reason to focus on "more-of-the-same" vendors for your company, too.
Pretend for just one minute that YOU are the owner of that little coffee shop and diner down the street. It's unlikely all of your daily needs would come from just one distributor, so it's easy to identify which areas where you might need to have multiple suppliers —
Multiple vendors for dishes, glassware, and utensils
A different one for the heavy coffee mugs
And a different one for the Styrofoam cups and to-go boxes
And another for your pots, pans, and cooking utensils
There's a vendor to lease the coffee machines
And another for the actual coffee grounds
And another for the filters
And then there's the soda supplier
And the water supplier
Multiple vendors for perishable food products like bread and fruit
And more for non-perishables like sugar, flour, ketchup
