〜(さ)せていただく: humbly do (with your permission)

A polite way to say that you do something, as if you were given permission.

Causative te-form + いただく: 紹介させていただきます, 休ませていただきます. Very common in business. Use it when the listener's permission matters or the action benefits them. Overuse sounds heavy; plain 〜いたします is often enough.
