The Next Frontier for ISOs: Back-Office Automation

The B2B payments landscape is transforming. Merchants are demanding consumer-like digital payment experiences for their payables and receivables — but most are stuck with clunky, paper-based processes.

For Independent Sales Organizations (ISOs), this shift presents a massive opportunity: Extend your front-office success in POS and e-commerce into the back office, where your merchants need you most.

That’s where Cashflow.io comes in.

We built our platform specifically for ISOs — giving you a way to expand your portfolio, generate recurring revenue, and make your merchants stickier than ever.

The ISO Advantage: Add Revenue Without Adding Complexity

ISOs have mastered the art of helping merchants accept payments. But back-office automation? That’s a wide-open lane — and a game-changer for portfolio growth.

Here’s how Cashflow.io turns that opportunity into reality:


  • Earn Net-New Revenue
    Offer merchants a back-office SaaS solution for payables and receivables — and collect 30% of monthly platform fees.

  • Seamless Integration
    No need to disrupt your merchants' existing processing relationships. Simply plug in their API key, and they’re ready to go.

  • Boost Merchant Stickiness
    You’ve already won their POS or e-commerce business. Now close the last gap with a full-service back-office automation tool that makes you indispensable.

What Makes Cashflow.io Different?

Not all B2B automation platforms are built for ISOs. We are.


  1. Multi-Account Support
    Manage multiple MIDs, bank accounts, currencies, and locations — perfect for franchises, multi-location operations, and treasury management.

  2. Custom API Solutions
    Our development team adapts quickly to merchant needs, modernizing legacy ERP systems and delivering tailor-made integrations.

  3. Simple, Intuitive UX
    We call it “Fisher Price for B2B” — an easy-to-use front end with powerful back-end technology that merchants love.

  4. White-Glove Customer Service
    We handle onboarding, support, and issue resolution. You get the benefits of a turnkey partnership without added operational load.

Why Now?

Platforms like Bill.com and Melio opened the door for B2B automation. But here’s the catch — they aren’t designed for ISO partnerships.

Cashflow.io is.

We combine SaaS automation, bring-your-own processing, and ISO-friendly revenue-sharing into one easy-to-deploy solution that gives you:


  • Recurring, predictable revenue

  • Stronger merchant relationships

  • A competitive edge in the payments market
