Phase 3 means more sites, more participants and a pivotal data set. Capture keeps every site on one locked form version, one randomization design and one audit trail, built the same self-serve way as a smaller study.

What changes at Phase 3
A pivotal study adds sites, participants and scrutiny, not necessarily complexity in the software itself. Capture keeps the same visual study builder for a 5-site Phase 3 study as a single-site Phase 1, with the coordination features multi-site work actually needs.

Allocation
Set your arms, block size and stratification once at study setup. Allocation happens automatically the moment a participant is enrolled, the same way at every site.
Day 28 is an Arm B only visit, so Arm A participants never see it.
Data quality at scale
A pivotal data set cannot wait weeks for a monitor to catch a bad value. Edit checks raise auto-queries the moment a site enters something that breaks a rule, across every site at once.

Add sites, forms and a randomization design in the free sandbox. Nothing is live until you say so.
Before you switch
No per-site or setup fees. Pricing applies once the study goes live, not to adding sites during the build.
21 CFR Part 11-aligned controls, field-level audit trail and verified e-signatures apply the same way at every site.
Sites are added by inviting a coordinator and sharing a QR enrollment link, not by rebuilding the study.
Moving an existing Phase 2 build forward, or starting fresh for Phase 3, both use the same visual study builder.
Email support and documentation for every plan; Enterprise adds dedicated support and validation assistance.
Capture hosts data in the EU (Frankfurt) or US (N. Virginia), chosen at study setup. Multi-site coordination features work the same across sites regardless of country; confirm your specific regulatory submission requirements separately.
There is no hard site limit in the platform. Each site gets its own coordinator portal and participant numbering under the same study.
Yes. Approved forms are locked for live use and shared identically across every site, so there is no drift between sites after an amendment.
The randomization design, arms, block size and any stratification factor, is set once at study setup and applied automatically at enrollment, the same way at every site.
Yes. Exports can be filtered by site and by date range.
No. There are no per-site or setup fees. Adding a site means inviting a coordinator and sharing an enrollment link.
