Best QMS for IVD startups in 2026

In Vitro Diagnostic software sits in a specific regulatory position. In Europe, IVDR 2017/746 applies -- a separate regulation from EU MDR with its own classification system and conformity assessment requirements. In the US, the FDA regulates IVD software under a distinct set of guidance documents. In both markets, the underlying quality management requirements are substantially similar to those for other SaMD.

If you are building software that supports laboratory analysis, diagnostic interpretation, or clinical decision support based on in vitro test results, here is what compliance looks like and which QMS tools work for your situation.

IVD software and the regulatory framework

The key question for IVD software is the same as for any SaMD: what does your software claim to do?

Under IVDR, software that is intended to provide information for diagnostic purposes -- interpreting test results, flagging abnormal values, supporting laboratory workflow decisions -- is regulated as an IVD. Classification depends on the risk level of the diagnostic purpose.

The QMS requirements under IVDR are closely aligned with ISO 13485. Your technical documentation needs to demonstrate requirements traceability, verification and validation of the software, risk management, and a structured release process. This is the same evidence base as standard SaMD compliance.

What IVD software teams need from a QMS

• Documented software requirements linked to verifications and test evidence
• Traceability matrix
• Risk analysis under ISO 14971 covering IVD-specific failure modes
• Structured release management
• Post-market performance follow-up (PMPF) for IVDR
• Document control and SOPs

The good news: if you get the underlying QMS right, the IVD-specific documentation (analytical performance studies, scientific validity assessment) attaches as supporting evidence to the relevant records. It does not require a fundamentally different QMS structure.

The options

| Tool | IVDR/IVD aligned | Software-focused | Free tier | Starting price | |---|---|---|---|---| | QualiHQ | Yes | Yes | Yes | Free | | Qualio | Yes | Partial | No | ~$500-800+/month | | Greenlight Guru | MDR-focused, partial IVDR | Partial | No | ~$1,000+/month | | MasterControl | Yes | No | No | Enterprise |

QualiHQ

Covers the core QMS requirements that IVDR and FDA IVD guidance expect: requirements management, verifications, traceability, release management, risk analysis, CAPA, and document control. AI generation from your existing product documentation. Free to start.

For IVDR, the conformity assessment pathway for IVD software is similar enough to MDR that the evidence structure QualiHQ produces maps directly.

Best for: IVD software startups where developers are managing compliance.

Qualio

ISO 13485 aligned and broadly applicable to IVD companies. Strong document control. Built for quality teams.

Best for: IVD companies with a dedicated quality manager.

Greenlight Guru

Strong for MDR, less specifically designed for IVDR. The hardware-centric features are less relevant for pure IVD software. Worth evaluating if you have a combination product.

Best for: Hardware IVD companies with a quality team.

The recommendation

IVD software compliance is not fundamentally different from other SaMD compliance. Get the core QMS in place -- requirements, verifications, traceability, releases, risk analysis -- and layer the IVD-specific documentation on top. Start with a tool designed for software teams doing this themselves.

QualiHQ is free to start. Build your IVD software QMS from your product documentation. No credit card.
