There are 2 ways to make money in business…Cut costs or increase sales or both…
If the pre-shredded cheese is satisfactory, you have to decide if the extra labour to shred your own is a good investment…Could that time be better used “growing” your sales…
I have no idea how much time is involved in shredding your own cheese but say for sake of argument it is 2 hours a days with prep, shredding, cleanup time, etc…Plus there is the cost of “wear and tear” on your equipment…Plus there is a consideration of consistency…Plus if your employee is shredding cheese are they able to answer the phone as quick? Even a slight delay may prevent you from the offering the best customer service possible…
Now consider if you take that time and use it for marketing…Get your staffer to make phone calls to your data base or random folks that have not ordered from you…Even a few extra pies a day will give you a better return than the money you save on cheese…
This is not an “exact” science so all variables have to be considered to determine what will work best in your situation…Good luck…
