Typical portal notice
“An addendum has been issued.”
Your estimator must retrieve the files, compare versions, find the material changes, assign owners, and confirm acknowledgement.
Public bid amendment monitoring
Don't lose a public bid to a late amendment.
Send us one active solicitation. We watch the official public source through deadline and deliver a reviewed brief showing what changed, what it affects, and what your team must acknowledge.
If the baseline is useful, monitoring is $149 for one pursuit for up to 30 calendar days.
- Official public sources
- Human-reviewed alerts
- No automatic submission

An alert tells you a file appeared. Your team still has to work out what to do.
Amendment Sentinel brief
- Exact official source and posting time
- Before-and-after requirement changes
- Affected price, scope, forms, and deadlines
- Required action, suggested owner, and acknowledgement status
How the founding pilot works
One pursuit. One accountable workflow.
Share the solicitation URL and current deadline. No private files are required for the founding pilot.
We inventory the public package, existing amendments, key dates, and acknowledgement requirements.
When the public source changes, a Truvo Digital operator verifies the finding and emails the source-linked action brief.

Straight answers
What this is—and what it is not.
How is this different from BidNet or portal alerts?
Those services notify you that something changed. This pilot owns the next step: retrieving the public artifact, checking the change, and sending the action brief for your live pursuit.
How is this different from VisibleThread Compare Docs?
VisibleThread is document-comparison software. Amendment Sentinel is a managed, per-pursuit service: we watch the official public source and deliver the reviewed monitoring-to-action handoff without requiring an enterprise software license.
What sources are included?
Public solicitation pages and public attachments that can be accessed without credentials or bypassing portal controls. Login-only, controlled, export-restricted, classified, and proprietary materials are excluded from the founding pilot.
Does this guarantee compliance?
No. Amendment Sentinel provides monitoring and proposal-support information, not legal advice or a compliance guarantee. Your team remains responsible for reviewing and submitting the bid.
Accountable delivery
Technology-assisted. Human-verified.
Monitoring and document-comparison tools surface potential changes. Before any material alert reaches your team, a Truvo Digital operator verifies it against the official public source. No automated bid decisions or submissions.
