QPQ = quid pro quo or "this for that", meaning an exchange, usually even or fair. A basic principle in maintaining relationships and partnerships.
We can get a discount on legal billings if we give them QPQ next quarter on our accounting fee.

The popular 'quid pro quo' universe is the one first used in rillrill's Whamilton fanfiction and is a popular AU in the Hamilton Community. The universe is a modern day interpretation with George Washington, Alexander Hamilton and many of their historical acquaintances as political figures.
