# Partnerships vs. sales internships: what is the difference?

## How many additional customers cover the setup cost?

A fictional partnership costs $15,000 to set up and contributes $5,500 per genuinely additional customer after the listed customer-level costs. Assume no other costs or benefits.

### Do not confuse introductions with customers

| Outcome | Contribution after setup |
| --- | --- |
| Two additional customers | 2 × $5,500 − $15,000 |
| Three additional customers | 3 × $5,500 − $15,000 |

## Your turn

What is the minimum whole number of additional customers needed to cover setup? Would three introductions satisfy it?
