What our partners say about Stax
"I would highly recommend this program to any SaaS partner who is looking to significantly increase their payments revenue and exceed their goals. Both the technology and service offering have been top notch and we truly feel that Stax is an extension of the Fishbowl team."
—Kendrick Hair, Chief Evangelist at Fishbowl
“From the onboarding perspective, it’s a knock out of the park. The sentiment is that the support is tremendously better, which makes our experience for our clients a lot better.
—Chris Meseke, Head of Product at Sera
"Stax is holding true to their motto of “meeting partners where they are” in their payment journey. We experienced this when we transitioned to Stax Connect Plus. We found their team members to be attentive to both our needs and our customers. Their expertise was instrumental in implementing a tailored program model, providing a seamless payment experience. We’re glad we adopted this as a part of our partnership."
—Allen G. Garber, Vice President & General Manager at DiamondSIS
