Evidence system
Evidence should be structured before a verifier asks for it.
TonneGrid Evidence turns project files into a governed evidence room with metadata, access control, review status, and batch-level context. It is designed for teams that need every document to answer a practical question: what does this prove, who reviewed it, and where was it used?
Metadata model
Tag evidence by project, batch, vintage, standard, document type, reporting period, and claim relationship.
Verifier rooms
Create focused review spaces for VVBs, auditors, buyers, and internal approvers with clean access boundaries.
Review history
Capture document status, comments, owner responses, and final approval decisions without email archaeology.
Diligence packs
Assemble buyer-ready evidence packages from approved files and live project context.
Collect
Bring baseline studies, monitoring records, contracts, reports, and certificates into one vault.
Classify
Add metadata so evidence is searchable by project, batch, verifier request, and claim usage.
Review
Route documents through verifier, internal, and buyer-facing review states.
Share
Open controlled rooms without losing the audit trail of what was shared and why.
Make your evidence room buyer and verifier ready.
Give reviewers the right proof, context, and status without rebuilding folders for every request.
