ISO vs. ISV: Which Payment Model Actually Wins for SaaS?
ISO vs. ISV is the wrong question for most SaaS platforms in 2026. Here's the four-role framework that actually decides which payment model wins.
Patient billing is one of the biggest pain points in healthcare software. Here's how embedded payments fix it and unlock a new revenue line for platforms.

Healthcare billing is one of the few consumer experiences that has actively gotten worse over the last decade. About 100 million Americans now carry a combined $220 billion in medical debt, and patient financial responsibility keeps climbing as deductibles rise.
Providers feel it on the other side: days in accounts receivable keep stretching, and collection shortfalls have only worsened since medical debt began being removed from credit reports.
For the healthcare software platforms serving this industry (practice management systems, EHRs, patient portals, RCM tools, telehealth apps, behavioral health SaaS), this is the single biggest operational pain point their users face every day.
The platforms that embed payments directly into their product don't just improve billing. They turn healthcare's messiest workflow into a competitive moat, and payments themselves into a revenue line.
Healthcare payments don't behave like retail or subscription billing. Every encounter touches multiple parties (patient, provider, primary insurer, secondary insurer, sometimes a third), each with its own rules, timing, and documentation. That structure is the root cause of almost every downstream billing failure.
The share of payments that come directly from patients has risen steadily as high-deductible plans have become the norm. Out-of-pocket healthcare spending grew 5.9% to $556.6 billion in 2024, and average per-capita out-of-pocket costs now exceed $1,600, before insurance premiums.
The problem is that patients often don't know their real balance until weeks after the visit, when a paper statement arrives. 70% of consumers still receive medical bills through the mail, but only 9% want to pay by paper check. That mismatch is where collections break down.
Software platforms that bring balances, eligibility, and payment into a single patient-facing flow close that gap. Practices using digital payment options collect roughly 30% more patient balances than those relying on paper statements alone.
Provider-side payments are just as messy. A single claim might involve a primary payer, a secondary payer, patient cost-sharing, and post-adjudication adjustments, often settling weeks or months after the service.
Platforms that can ingest remittance data, match it to patient accounts, and move provider reimbursements on a modern rail collapse a workflow that today eats hours of billing staff time per day.
Healthcare doesn't get to choose between HIPAA and PCI DSS — platforms have to handle both. Card data flows through PCI-governed infrastructure; anything touching PHI sits under HIPAA; and many states layer their own protections on top of that.
A payments layer that isn't purpose-built for this environment becomes a liability the moment it touches a patient record.
The headline medical debt numbers are staggering at the macro level, but what matters for healthcare software platforms is how broken billing shows up in the day-to-day experience of the providers and patients inside their products.
Every one of these failure modes has a software fix. The platforms that ship it win.
Embedded payments means the entire payment lifecycle (patient pay-in, provider reimbursement, plan setup, refunds, reporting) lives inside your platform rather than being handed off to an outside processor. For healthcare SaaS, that translates into a handful of capabilities that matter more than the generic pitch.
Patients pay inside the portal, the app, or the text-to-pay link the practice sent them. No redirect, no separate login, no paper statement cycle.
Rising deductibles mean more patients need to spread balances over time. Platforms that can create plans, run autopay against cards or ACH on file, and adjust terms inside the same UI collect more.
Payments tied to real-time eligibility checks let practices collect the right patient portion at the right time instead of chasing balances after the fact.
Provider reimbursements, refunds to patients, and payouts to affiliated clinicians need to move on the right rail for the situation, whether card, ACH, or instant rails.
HIPAA and PCI-compliant infrastructure. Not "we'll figure it out." Built in from day one.
Embedded payments aren't just a feature. Done right, they add 30–50% to effective revenue per customer without touching SaaS pricing. That economics shift is why every serious vertical SaaS company is moving in this direction.
Most healthcare platforms start with whatever processor was easiest to plug in, typically Stripe Connect or a legacy gateway bolted on through a reseller. That works until it doesn't.
As volume grows, the economics get worse, the integration gets more brittle, and the feature gap between "payments" and "embedded payments" becomes a competitive problem.
A partner built for vertical SaaS should offer:
Coinflow is a payments infrastructure built for software platforms that want to own the payments experience their customers live inside.
For healthcare SaaS (practice management, patient portals, RCM, telehealth, behavioral health, specialty EHRs), that means a single API that handles patient pay-in, provider reimbursements, submerchant onboarding, and settlement, with PCI DSS Service Provider Level 1 and SOC 2 compliance built in.
We support:
For early-stage healthcare SaaS platforms under $10M ARR, with 20–1,000 submerchants, Coinflow Launchpad is an accelerator program built around exactly this use case. No setup fees, no platform fees, and revenue share from the first transaction.
If payments are still a feature you pass through rather than a revenue line you own, talk to our team. We'll model out what switching looks like for your specific setup.
