Overview
In federal procurement
DA01 is the federal PSC for business-application and application-development support delivered as labor: developers and engineers building and supporting custom applications. Contracting officers use it to classify bespoke software-build requirements on a services (labor-hour or task) basis. It is one of the IT-services PSCs ITC filed in SAM, and it pairs with NAICS 541511 on most custom-build solicitations.

The same capability, commercially
The same work, sold commercially, is straightforward custom-software delivery: a team building and maintaining an application to a buyer’s spec. Mid-market and SMB firms buy it without any PSC. ITC ships its own products on the same Next.js and TypeScript stack it uses on client engagements, which is the demonstration behind the capability.
Mid-market, SMB, and enterprise buyers.
A PSC only matters when the buyer is a federal agency. The underlying service is the same for commercial buyers.

Common questions
What is the difference between PSC DA01 and DA10?
DA01 classifies application development and support delivered as labor (a services engagement); DA10 classifies the same business-application capability delivered as Software as a Service. The build-as-labor versus buy-as-SaaS distinction drives which code applies.
