Federal exclusion screening vs checking SAM.gov by hand
Checking SAM.gov by hand confirms whether a vendor is excluded today, but it leaves no dated record of what the list said at award time, doesn't scale across a vendor portfolio, and can't answer the point-in-time question every auditor asks. SAM.gov carries 324,126 active exclusion records; in one bounded Fonteum analysis, 112 prime awards worth $1.6M went to 21 recipients while each held an active exclusion.

From a manual SAM.gov lookup to a retained, source-dated screen
| Capability | Manual SAM.gov checks | Fonteum |
|---|---|---|
| Coverage | One entity at a time, typed into the SAM.gov search box. | The full GSA exclusion registry — 324,126 active records — screened in a single pass. |
| Point-in-time status | Today's status only — the screen shows what the list says now. | Current screening plus bounded award-date analyses. Fonteum does not claim universal historical replay of SAM.gov rows. |
| Identity resolution | A name or UEI typed by hand, with no record of how it was matched. | UEI-, CAGE-, and name-keyed match against the registry, with the basis recorded. |
| Portfolio scale | Re-check every vendor, by hand, every cycle. | The free procurement workflow checks the first 10 UEIs on screen; it does not create a download or monitoring. |
| Award-time evidence | No record of a vendor's status on the day the contract was awarded. | An exclusion-active-at-award-date join — the mechanism behind the Leakage Report. |
| Match provenance | A screenshot with a timestamp you have to trust. | Matches expose source record, exclusion type, and observation fields where the response supplies them. |
| Refresh cadence | As current as your last manual lookup. | Loaded SAM.gov observation dates are reported separately from publisher or job cadence. |
| Audit trail | A folder of dated PDFs, assembled after the fact. | The free procurement result stays on screen and does not create a report artifact. |
Descriptions reflect the manual SAM.gov screening pattern — searching the public exclusion registry by hand — not any single vendor or service. SAM.gov remains the authoritative source; figures cite Fonteum's published federal-contracting research.
What a manual SAM.gov check leaves uncovered
An award to an excluded party is the failure mode
Federal rules bar awards to excluded parties (FAR 9.405; 2 CFR part 180). Yet in one bounded Fonteum analysis, 112 prime awards worth $1.6M went to 21 recipients while each held an active federal exclusion. A manual SAM.gov check at award time is the control that is supposed to catch this — and it is the control that is hardest to prove ran.
The point-in-time question is the one a manual check can't answer
A live SAM.gov lookup tells you current status. A past-date claim requires a retained row or a bounded published analysis using the source's effective-date fields. Fonteum has only a small procurement-history set and does not offer universal SAM.gov replay.
Manual checks don't scale across a vendor portfolio
Screening one vendor in the SAM.gov UI is quick. The free Fonteum workflow checks the first 10 UEIs on demand and stays on screen; larger procurement portfolios are outside that free workflow.
A clear result needs a record, not a screenshot
Suspension-and-debarment programs are judged on evidence. The free workflow exposes its result on screen but does not create a downloadable report, email, or monitoring schedule.

Common questions
- Can't I just check SAM.gov myself for free?
- Yes — SAM.gov exclusion search is free and authoritative for a single entity's status today. The limits show up at scale and over time: a manual check doesn't retain what the list said on a past date, doesn't produce a dated audit record, and is impractical to run across a large vendor portfolio every solicitation cycle.
- What does a manual SAM.gov check miss?
- It misses the award-time record and the point-in-time question. A live lookup shows current status, not what SAM.gov said when a contract was signed. It also leaves no dated, re-derivable evidence trail, and it doesn't scale: each of the 324,126 active exclusion records and each vendor has to be checked one at a time.
- How can a vendor receive an award while excluded?
- Most often a screening gap, not intent: the award-time check is skipped, run against a stale copy, or matched on a name that doesn't tie to the excluded entity. In one bounded Fonteum analysis, 112 prime awards worth $1.6M went to 21 recipients during an active exclusion window — exactly the gap an award-time, point-in-time screen closes.
- How does Fonteum prove a vendor's status at award time?
- Fonteum does not claim universal SAM.gov row replay. Its bounded award analysis compares award dates with published exclusion-effective intervals, and production procurement history currently contains only a small retained set. A current screen alone cannot prove a past status.
- Does this replace SAM.gov?
- No. SAM.gov remains authoritative. Fonteum adds current registry screening with the observation metadata available in the response. The free workflow stays on screen and does not create a report artifact; there is no universal historical replay.
