Paperwork disqualifications on 나라장터 — H1 2026, counted.
We aggregated every negotiated-contract (협상에 의한 계약) service tender opened between Jan 9 and Jul 8, 2026 from public 나라장터 bid-opening records: 32,319 notices, 68,912 bids, 12,796 distinct bidders. This report covers the bidders who were cut before their proposal was ever evaluated — on paperwork alone.
The four preventable grounds
Of all disqualification reasons recorded in bid-opening data, four are pure pre-submission paperwork — checkable before the deadline: proposal not submitted, required documents not submitted, bid over the project budget, and company-name/CEO mismatch across documents. In H1 2026 they disqualified 423 distinct bidders in 734 bid entries.
| Ground | Entries | Distinct bidders |
|---|---|---|
| Proposal not submitted | 417 | 247 |
| Required documents not submitted | 225 | 107 |
| Bid over project budget | 75 | 64 |
| Name/CEO mismatch across documents | 17 | 16 |

How much was at stake in those slips
Estimated price (추정가격) of the 525 notices where a preventable slip occurred. These are not small tenders: 60% are ₩100M+, and the largest single notice was ₩4.36B.
It happens every month, not in one bad season
Preventable paperwork disqualifications occur every month — 73 to 154 entries a month through H1 (July covers only the first week of the period). This is not a one-off accident season; it is a constant tax on bidders who assemble packages under deadline pressure.
The full picture
For context, all recorded grounds. The largest — negotiation-evaluation ineligibility (5,502 bidders) — is about proposal substance, a different problem. The paperwork grounds above come earlier: a gate a bid must pass before its proposal is even evaluated. Price-over-예정가격 (213 entries) is excluded from the preventable set: the reserve price is drawn at opening and cannot be checked in advance.

Negotiation-evaluation ineligibility (5,502 bidders) is omitted from this chart — it is proposal-substance, on a different scale; see the table below.

Method and limits
Source: public 나라장터 (G2B) bid-opening records — negotiated-contract service tenders opened 2026-01-09 through 2026-07-08. Counts are unique bidders per ground (a bidder can appear under multiple grounds) and raw bid entries.
How the headline figures relate: the per-ground bidder counts sum to 434, which exceeds the 423 distinct companies because a company disqualified on more than one ground is counted once per ground. The 525 notices exceed the company count because one company can be disqualified across several notices — the 734 bid entries are the raw total.
The ₩127.6B figure is the combined estimated price (추정가격) of the 525 notices where at least one preventable slip occurred — it measures what was at stake in those tenders, not lost revenue: a disqualified bidder was not guaranteed to win.
