As Per Your Request vs. Per Your Request
Both “as per your request” and “per your request” occur in business English. Cambridge labels “as per” formal, while Chicago treats the choice largely as style and favors plainer wording such as “as you requested” in many contexts.
“As per your request” is established formal business English, but “per your request” is shorter and “as you requested” is often plainer; choose by tone rather than treating “as per” as automatically ungrammatical.
Key details
Important caveats
Scope Boundary
This is mainly a register and editorial-style choice, not a universal grammar error test.
Further guidance
Application
Use the shorter wording when brevity fits, or rewrite as “as you requested” when a plainer personal construction suits the message.
Core Rule
“As per” can mean “according to” in formal business English; “per your request” expresses the same basic relationship more compactly.
Example
Formal: “As per your request, the signed copy is attached.” Concise: “Per your request, the signed copy is attached.” Plain: “As you requested, I’ve attached the signed copy.”
Practical Application
Use either established business form when the register calls for it, but choose deliberately: “as per your request” is more formal/formulaic, “per your request” is shorter, and “as you requested” is often the plainest option.
Reader Check
Ask whether the sentence benefits from formal business phrasing or simply needs to say that you acted on the recipient’s request. Do not treat “as per” as automatically ungrammatical.
