1. Stax Connect Helps You Understand and Grasp Payments

We’ll guide you through the ins and outs of accepting payments on your platform, from implementation to post-launch. Without a solid understanding of payments security, technology, and adoption, many platforms fail to truly realize the potential of Payments-Led Growth.

Safety and Security

Stax handles risk management, underwriting, compliance, and a sponsor bank relationship for you, so your customers can easily apply and enroll.

Implementation Strategy

Our Partner Success Team will formulate a path to success so you can integrate payments with technology that makes the most sense for your customers.

Onboarding Support

With white-label enrollment options or full integration with the Stax API, Stax manages underwriting and approval of your merchants with automation and ample customer support.

2. Establish ROI and Apply Payments

ROI modeling uncovers the impacts of integrating payments beyond revenue and aligns with the “why” of payment integration. Using payments specific to your business will scale growth with monetizable features that make sense, such as surcharging, ACH, custom pricing, etc.

Deep Industry Understanding

Our team brings experience and knowledge of your SaaS vertical and works closely with you to understand the goals, impact opportunities, and best practices to integrate payments into your platform.

ROI Modeling

We’ll show you the true impacts of integrating payments and give you the tools to effectively sell, implement, and scale with Payments-Led Growth.

Personal Collaboration and Education

No more cloud-based documents and chat robots. Our team will fly, drive, or even sprint, to collaborate on how Payments-Led Growth will impact your business.

3. Integrate Payments with the Stax API

Get started as soon as tomorrow with zero development and a proprietary white-labeled enrollment system or build custom enrollment flows through our API, with features such as surcharging, split payments, ACH, and more.

Custom Integration and Enrollment Options

Use our proprietary white-labeled enrollment system or have merchants sign up directly from your software or app with customizable enrollment flows.

One API For Everything

Build custom features as you go, without needing multiple APIs—add features such as surcharging, Card Present, and Card Not Present Payments.

Adaptable Revenue Opportunities

You decide whether you want to use surcharging to grow revenue and cover processing costs, or enable a custom fee structure for your customers' transactions.

4. Go-to-Market Planning

Without a plan to promote your new payments technology, processing volume stays stagnant and your Payments-Led Growth plan can fall flat. We’ll help you identify who your customers using payments are, and why they need to process payments through your platform.

Partner Marketing Portal

Make the lift of planning and executing on your campaign plans as easy as possible with a library of landing page templates, email content, blog content, webinar outlines, and more.

Campaign Support

We'll give you key insight into how payments will make an impact, whether you are targeting current merchants to switch from a previous payment processor, or attracting new customers with payments.

Promote Relevant Features

The most relevant and valuable features of your payments technology will build the most excitement for your customers, depending on their needs.
