When I said "adjusting up or down", I meant the size of the machines, not the prices. You know, like a 6 selection soda machine vs a 12 selection. I think the only time I might change pricing would be if a location requests commissions, or my costs increase dramatically in some other way.

I have seen all kinds of "formulas" for predicting sales.

For instance, the lady at the vending distributor figured you take roughly half the employees, multiplied by 26 days per month, then times average sale per employee (she used $2.50, based on $1.50 soda and $1.00 chip/candy). This would be your Gross Sales per month.
40 x 26 x 2.5 = $2,600!

Very ambitious numbers indeed!

Another formula I have read about depends on the type of employees. You calculate $2 per "white collar" employee per week, or $4 per "blue collar".

But yeah, there are so many variables to consider. Each location could vary widely. Especially with fewer than 100 employees. I'm sure demographics like ethnicity and gender could even play a role.

Seems my best bet starting out, would be to get a few good locations with no less than 70 employees. Get those machines paid off as soon as possible, then expand.

AZVendor, sounds like you have had a bad personal experience with USI before?

Let's forget about brands. Let's talk about a location with an average of 75 employees.
 

I have already considered all the logistics. Not going into this as a get-rich-quick scheme. It really comes down to sales projections.
Mainly interested in thoughts about whether a location with 75 employees could generate more than $200 per week between 2 machines (1 snack, 1 soda)?  Is there a reliable way of estimating the gross revenue from locations based on the number of employees?  I realize it could vary depending on the hours of operation, like a 5-day week vs 7-day week vs 24/7. For the sake of example, let's go with a 5 day workweek office environment with a break/lunch room.
 

What do most people do? Just plug in a couple machines blindly, then adjust up or down based on actual sales?
