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.

Quick answer

“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.

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.

In Regard To vs. With Regard To vs. In Reference To

“In regard to,” “with regard to,” and “in reference to” are established formal expressions meaning roughly “about” or “in connection with”; their main differences are phrasing and register rather than a sharp difference in core meaning. Treat the choice as register and style, not as a universal correctness contest; also avoid confusing these expressions with the closing “regards.”
