From site activation to database lock, each role sees what to do next. Sites screen and enter data, monitors verify, data managers freeze and lock, and sponsors watch it all on a live dashboard.

The workflow
Ethics approval, contract, initiation visit and delegation log, then one Activate button.
A guided screening flow assigns sequential numbers and handles rescreens.
Sites enter visit data, edit checks raise queries, monitors verify.
Data managers freeze and lock data field by field or in bulk.
Site activation
Each site passes a four-item checklist before it opens. Until it is activated, nobody can add, screen or randomize participants there, and the rule is enforced on the server, not just in the screen.
Pre-launch readiness
1 site activated
1 form not yet approved
Screening
Adding a subject follows a short guided flow. New subjects and rescreens are handled separately, numbers are assigned in sequence, and the site confirms the details before anything is saved.

Data quality
Edit checks raise queries as data is entered, and monitors raise their own. Everyone works the same list, with status, priority and age visible at a glance.

A free sandbox comes with sample data, so you can activate a site, screen a subject and raise a query in minutes.
Roles
Each role sees its own tasks and permissions. Site staff enter data, monitors verify, data managers freeze and lock, and only the principal investigator signs off the casebook.
Study owner
Builds and configures the study
Principal investigator
Oversees the site, signs off the casebook
Sub-investigator
Enters and signs clinical data
Study coordinator
Screens subjects, enters visit data
Monitor (CRA)
Verifies data, raises queries
Data manager
Reviews, freezes and locks data
Participant
Completes their own questionnaires
Oversight
The study dashboard pulls enrolment, compliance, safety and site risk into one view, filtered globally, by country or by site.

It is software that supports the daily work of running a trial: activating sites, screening and enrolling participants, collecting visit data, resolving queries and locking data. Capture handles these steps in the same system where the study is built.
Each site completes a four-item checklist: ethics approval, contract, site initiation visit and delegation log. An authorized user then activates the site, which is recorded in the audit trail.
Sequentially, never randomly, using the prefix and format you set. Rescreened subjects get a new number linked to their previous one.
Study owner, principal investigator, sub-investigator, study coordinator, monitor (CRA), data manager and participant, plus blinded and unblinded access for randomized studies.
Queries are raised automatically by edit checks or manually by monitors. They move from open to answered to closed, can be answered in place from the casebook, and can be exported to CSV.
Data managers freeze and lock data, field by field or in bulk. Unfreezing or unlocking requires a reason, and every change is in the audit trail.
Yes. The dashboard shows enrolment, compliance, safety and site risk, filtered globally, by country or by site.
Yes. The free sandbox includes sample data, so you can walk through each step. No credit card is needed.
