PSC DA10 is the subscription twin of DA01. The manual defines it as analysis, design, development, code, test and release packaging delivered as a service contract, along with off-the-shelf business software licensed for a defined period. Its framing note is the one that trips people up: software as a service, service contracts, subscription-based software provisioning, and device rentals are all treated as services. End-user productivity software is excluded and belongs in the DE or 7E codes. FY2025 obligations were $8.6 billion.
The channel, not the publisher
$3.3 billion went to 541519, Other Computer Related Services, which is the reseller and solution-provider industry. Software Publishers (511210) took $1.73 billion, less than half of it. 541512 follows at $1.10 billion and 541511 at $1.03 billion. Even 334111, Electronic Computer Manufacturing, shows $361 million against a software-as-a-service code, because hardware resellers carry that registration while brokering subscriptions.
PSC and NAICS in one line
The PSC classifies the purchase, the NAICS code classifies the seller, and on DA10 the seller is usually not the maker.
For a software company, that means federal SaaS revenue mostly arrives through partners. Track DA10 and 7A21 together to see both the subscription and perpetual-license sides of the same product line.

Frequently Asked
PSC DA10 questions, answered.
What does PSC DA10 cover?
Business application and application development capability delivered as a service: SaaS, subscription licensing, and service contracts covering off-the-shelf business software and the development work around it.
What NAICS codes win DA10 work?
541519 led FY2025 at $3.3 billion, roughly double the $1.73 billion that went to Software Publishers (511210). 541512 and 541511 follow at $1.10 billion and $1.03 billion.
Does DA10 include end-user productivity software?
No. The manual excludes end-user productivity software from DA10. Email, word processing, spreadsheets, and presentation tools delivered as a service belong to DE10, and their perpetual-license equivalents to 7E20.
How do I tell a DA10 buy from a 7A21 buy?
License duration. Software licensed for a defined term is a service and codes to DA10. Software licensed indefinitely is a product and codes to 7A21. The functional software can be identical.
