Independent Selling Organization (ISO)

Help more merchants accept payments fast

Serve the growing number of small and mid-size business (SMB) merchants adopting digital payments with a partner that helps you get to market fast with flexible payment solutions.

Solutions

Build a more profitable portfolio with payments in it

Choose your partnership model and equip your merchants with complete payment tech, lightning-fast onboarding, and dedicated, hands-on support.

Two partner models, two ways to get paid

Every ISO has unique business goals and revenue strategies. CSG offers two partnership paths to help you start earning from payments. No matter the model, we’ll handle compliance and risk liability.

  • Referral partnership: Hand off your leads directly to CSG and earn a share of the volume processed per referral that we close. Delight customers with a proven partner.

  • Reseller partnership: Go to market reselling CSG Payments with your team, your brand, and your pricing. Keep the difference between your buy and sell rate. 

Rely on a single partner for payments

No need to source different vendors for different channels or payment types. CSG Payments has end to end solutions for all your merchants’ needs.

  • Omnichannel payments: Over the phone, in-person, online, and via a convenient web portal we take payments through multiple channels.

  • Diverse payment methods: Cards, ACH, and digital wallets ensure popular consumer preferences are being met.

  • Centralized reporting and payment operations: Merchants get access to a web-based platform to handle the entire payment lifecycle.

Get merchants deployed in days, not weeks

Skip the long implementation cycles. CSG Payments provides a streamlined setup that removes technical hurdles, making it easy for your merchants to get to market and start generating revenue faster.

  • Make the process effortless for your merchants with average payment processing and approval in under 24 hours.

  • A simple payment connection between your customers’ website or application means they can start processing payments without heavy integrations.

Hands-on support for you and your merchants

We don’t just turn on payments and walk away. Get dedicated support that’s consistently rated as outstanding, responsive, and highly reliable.

  • Dedicated teams guide your merchants through implementation, ensure they're highly successful, and deliver training that is tailored specifically to your customers' needs. 

  • Gain access to extensive technical documentation and an AI-powered chatbot for fast, effective answers whenever you need them.

  • Stay in the know with our newsletters, blogs, product announcements, and release notes.
