Business English Phrase Cheat Sheet

For software engineers working with US / European clients

How to use this: don't try to memorize all of it. Take one section per week. Pick the 3–4 phrases in that section you'd actually use, say them out loud five times each, and force yourself to use them at work that week. A phrase you've said out loud is retrievable; a phrase you've only read is not.
