The adverbial phrase as per, which comes from business writing, usually means in accordance with, as in these examples:
As per the earlier agreement, Hero Honda was not allowed to export bikes. [mydigitalfc.com]
The time of the contract will depend on the user as per his convenience. [PR Wall Street]
As per is especially common in Indian publications. We can’t explain this. Outside India, careful writers tend to avoid as per because it has a jargonistic tone, and simply saying in accordance with or according to usually sounds more natural.
Plus, as per is redundant. Per, without as, conveys the same meaning. And in some cases, as on its own would work just as well as as per, especially with the common phrase as per usual—for example:
As per usual, Richard Blais once again collected all 3 first place votes, with Angelo swapping places with Tiffani to round out the top three. [Television Blend]
Here, per could be removed with no loss of meaning.
