Today’s Japanese Business Slang is “NARU-HAYA”.
“NARU-HAYA” is the abbreviation of “NARUBEKU HAYAKU”, meaning “as soon as possible”.
Some examples are 「資料、なるはやでお願いします。」(”Please, prepare the documents as soon as possible.”) and 「これ、なるはやで、できるかな。」(”Can you do it ASAP?”).
Why don’t you use this phrase?
