How is UPSTACK different from traditional sales agents?
If your services are free to your clients, how do you get paid?

No. Our participation doesn't increase your costs. UPSTACK acts as an outsourced extension of the vendor's sales and support organization, which reduces their cost of sale and overhead. In fact, most of our customers receive better pricing and terms than they would by going direct.
What happens if I don’t move forward with a new solution recommended by UPSTACK?

We’re also happy to connect you with current clients who can speak to their experience.
