PSC DE01 is the end-user support labor code. The manual's scope is long and specific: Tier 1 and Tier 2 help and service desk, deskside support, adds, moves and changes, workspace support, collaboration and productivity software technical support, audio-video and video teleconferencing support for conference rooms and telepresence rooms, and printer support including managed print services for multifunction print, scan, fax, and copy devices. It excludes mobile device support, which has its own code, DE02. FY2025 obligations totalled $1.73 billion.
No one owns this code
The distribution is flatter than almost any other D-family code. Other Computer Related Services (541519) leads with only $435 million, then Computer Systems Design Services (541512) at $369 million, Computer Facilities Management Services (541513) at $150 million, software publishers 511210 at $133 million, and 541511 at $109 million. Five industries within about $435M of each other on a $1.7B code is what a commoditized service looks like in procurement data.
One line on the two codes
The PSC is about the requirement; the NAICS code is about the company that filled it.
DE01 is winnable by small firms because no registration confers an advantage, but it is also priced accordingly. If your differentiation is mobile device management, bid DE02, where the pool is much smaller.

Frequently Asked
PSC DE01 questions, answered.
What does PSC DE01 cover?
End-user support labor: Tier 1 and 2 help desk, deskside support, adds, moves and changes, workspace and productivity software support, audio-video and VTC conferencing support, and printer and managed print services.
What NAICS codes win DE01 work?
Other Computer Related Services (541519) at $435 million, Computer Systems Design Services (541512) at $369 million, and Computer Facilities Management Services (541513) at $150 million lead, but no registration takes even a third of the code.
Does DE01 cover mobile devices?
No. Mobile device support is excluded from DE01 and coded DE02, with DE11 covering managed mobility delivered as a service.
Is video teleconferencing support really in this code?
Yes. The manual places audio-video and VTC support for conference rooms and dedicated telepresence rooms inside DE01, alongside help desk and print support.
