1
Start with the newest official action
Open the issuing agency's current opportunity page and notice history. Confirm whether the latest action is active, amended, cancelled, withdrawn, awarded, or closed before relying on earlier instructions.
Public proposal control
The original RFP may no longer control.
An addendum can change the deadline, required form, eligibility condition, package name, or submission route. Use this seven-step checklist before your team treats the first document it downloaded as current.
Customer boundary: This checklist supports administrative control. Your company retains strategy, pricing, technical content, representations, approvals, credentials, and final submission.
Seven checks
Reconcile the opportunity before proposal work accelerates.
Record the source and result for each step. If evidence is unavailable or official sources conflict, mark the item unresolved and continue only with conclusions the evidence supports.
2
Build the complete addendum list
List every amendment, addendum, Q&A release, revised attachment, and incorporated notice by date. Do not assume the files appear in chronological order or in only one section of the site.
3
Compare every deadline and timezone
Check the summary, narrative, addenda, attachments, and submission portal. Preserve conflicting values instead of silently choosing one, and seek authoritative clarification when the conflict could affect delivery.
4
Track required acknowledgments
Identify each addendum that must be signed, initialed, uploaded, or acknowledged in a portal. Record the required location and the person responsible for completing it.
5
Reconcile forms and attachments
Mark each named file as reviewed, pending, inaccessible, or customer supplied. Capture renamed or superseded forms and never treat a filename as proof that its contents were reviewed.
6
Separate submission channels
Map the final proposal route separately from Q&A forms, support email, qualification portals, site-information portals, and file-transfer links. A valid question channel may still be an invalid proposal channel.
7
Run an independent final pass
Have a second review verify the newest action, terminal status, deadline, mandatory eligibility, required forms, acknowledgments, package naming, and submission route against the official sources.
Minimum control record
Make the evidence easy to audit.
