Frequently asked questions
What if we need a Q-Sub meeting first?

We'll recommend a Q-Sub if your device is novel or the pathway is genuinely unclear. The Q-Sub prep and meeting management is included in the Complex and SaMD tiers, or available as an add-on to Standard.

What happens if FDA sends an AI request?

We respond. Every tier includes post-submission support for AI request responses — 30, 60, or 90 days depending on tier. We draft the response, the consultant reviews it, and you submit it. Same team, same workflow.

Do I need to have all my test data before starting?

No. We scope the submission first, then map what testing you still need. We can help you select labs, write test protocols, and integrate results as they arrive — without holding up the sections that don't depend on test data.

How does the expert review actually work?

Your consultant has a dedicated view in the Complizen workspace. They review sections as they're completed, leave inline comments and tracked changes, and flag items that need your input. You see every comment, approve every change, and sign off before anything goes to FDA.

Who are your FDA consultants?

Former CDRH reviewers, RA professionals with 10–25 years of direct 510(k) experience, and regulatory affairs PhDs. All consultants have submitted multiple 510(k)s independently before joining the Complizen network. We'll introduce you to yours before kickoff.
