is Killing Your
Growth.

Two Models. One Clear Choice
for Modern Platforms.
Both route payments — but they differ fundamentally in speed, liability, and who owns the merchant relationship. Here is what separates them.
| Feature | PayFac | ISO |
|---|---|---|
| Account Type | Sub-merchant under master MID — no bank contract needed Instant Access |
Dedicated individual merchant ID with direct acquirer relationship |
| Onboarding | Minutes to hours — automated KYC/KYB, no manual underwriting Automated |
Days to weeks — traditional underwriting, paperwork, acquirer approval |
| Liability | PayFac owns fraud, chargebacks, AML, and PCI DSS Level 1 Full Coverage |
Acquiring bank carries primary liability — merchant manages own risk |
| Funds Flow | PayFac settles to sub-merchants after aggregating transactions | Settlement flows bank-to-merchant directly — ISO never touches funds No Funds Flow |
| Pricing Control | Fixed transparent flat-rate — simple but less negotiable at scale | Fully negotiable — interchange-plus, custom rates for high volume Rate Flexibility |
| Best For | SaaS platforms, marketplaces, embedded finance, startups Platforms |
High-volume merchants needing dedicated accounts and negotiated terms Established |

- You control pricing, branding, and onboarding experience
- Processing or targeting $1M+ monthly with margin focus
- Ready to invest in KYC, KYB, AML, and fraud infrastructure

ISO works when your business processes high predictable volume, you want a direct acquirer relationship, and you prefer not to carry underwriting or PCI compliance risk.
- Established merchant with high, predictable volume
- Want to negotiate custom interchange-plus rates
- Compliance burden and PCI Level 1 are dealbreakers
- Prefer a direct acquirer relationship over sub-merchant structure
- Early-stage SaaS adding payments without PayFac capital outlay
