Best way to loose money as a roaster is provide equipment.
Even if you got $20 per pound to the store (which is crazy talk) how many pounds would do have to sell to pay back a $17,000 two group Synesso machine? And a $2000 espresso grinder plus a $2000 Lab Grinder (you said highend)
Lets do the math:
High end coffee per pound roasted in bag cost: $8 (finished) leaving $12 profit
$21,000 / $12 = 1750 bags of coffee
Average coffee shop is going to use 50 pounds per week (this is way high estimate)
1750 pounds / 200 per month = 8.75 months to break even on equipment. Plus you have to pay off your roaster.
Do not forget about repairs and service you will need to provide.
This is based on over inflated sales numbers, lets do it for real.
The real numbers:
Equipment $21K, Profit per pound $4.4 = 4,667 1# bags to pay off equipment
4,667 / 25 pounds per week = 47 months to pay off equipment.
Now most coffee shops owners that do not have the cash to buy the gear probably will be out of business in two years as they should not be running a business to begin with. Restaurant business has the highest failure rate of any, do not kid your self that is what this is.
4 years to pay the equipment off before you break even. If you lay out gear for 5 stores your into equipment for over $100k in other peoples store which you have no control over. If you have that kind of cash laying around surely you can find a better investment than maybe break even in 4 years.
Most real roasters are not in the equipment business as John P stated. The guys in the equipment rental / lease business are mostly slimy sales people that sell floor sweeping coffee roasted by someone else (not all, most).
Finally $10+ coffee does not mean that is all profit.
Not to be the downer, just want you to have a real view of what your getting into. You can make money, it is not as easy as it looks that is all.
