Deidiker Accounting & Consulting LLC

Deidiker Accounting & Consulting LLC, a Missouri-based sole proprietorship and limited liability company, provides financial assistance and accounting support services to the federal government exclusively as a prime contractor on recurring purchase orders with the National Transportation Safety Board. The vendor operates outside SBA set-aside programs on most recent awards, though one 2024 purchase order carried a Total Small Business set-aside designation.

Deidiker's federal footprint is narrow and stable. The National Transportation Safety Board accounts for 100% of the vendor's fifteen awards across the source data window, with combined potential value of $808 thousand and $453 thousand in obligated dollars (56% realization rate). The vendor has maintained an annual purchase order cadence with NTSB since 2021, with contract values consistently in the $19.9 thousand to $24.9 thousand range. Recent awards include a $24.9 thousand purchase order for financial assistance services effective April 6, 2026 through November 30, 2026, and a $24.9 thousand purchase order for financial assistance support services running March 1, 2025 through February 28, 2026. Work is performed in West Plains, Missouri.

Deidiker operates under two parent vehicles at NTSB: an Indefinite Delivery Contract (NTSBD140001) carrying four task orders valued at $163 thousand combined, and a Blanket Purchase Agreement (9531BM18A0001) carrying three task orders valued at $145 thousand combined. The vendor's work spans financial management and accounting support under NAICS 541211 (Offices of Certified Public Accountants), with PSC coding split between Support-Management Financial (nine awards) and Support-Management Accounting (six awards). Activity remains flat at one award per year across the past five years. One award reaches ultimate completion within the next twenty-four months, exposing $25 thousand in potential recompete.
