Clinical Trial Vendor Categories | Clinical Vendor Compare

Frequently Asked Questions

How are vendors categorised on Clinical Vendor Compare?

Vendors are classified based on their primary service offering. Many vendors span multiple categories — they appear in their primary category and are tagged with secondary buckets so they surface in relevant searches.

Can a vendor appear in multiple categories?

Yes. Vendors that offer services across multiple domains (e.g. a CRO that also provides eClinical systems) are tagged with secondary categories. The primary category reflects their core business focus.

How do I suggest a new vendor category?

Contact us through the contact page or submit feedback. We review category suggestions quarterly and add new categories when there are enough vendors to justify a separate listing.

What does "verified" mean for vendor profiles?

Verified vendors have had their profile data cross-referenced against public sources, regulatory filings, and industry databases. Vendor profiles are updated regularly to reflect acquisitions, name changes, and service expansions.
