BATNA Best Alternative To a Negotiated Agreement — your fallback plan if the deal falls through, like walking out of a car dealership when they won't meet your price.
TCO Total Cost of Ownership — the full cost of a contract including fees, penalties, and extras you forgot about, like a "free" phone that costs $200 in activation fees.
SLA Service Level Agreement — the promised performance standard your supplier committed to, like a delivery guarantee with a refund if they're late.
Auto-renewal trap A clause that renews your contract automatically with price increases you didn't agree to — like a gym membership that keeps charging you every year.
Indexation formula A formula that automatically increases prices based on inflation — like your rent going up because the CPI rose, whether you got a raise or not.
Leverage Your bargaining power — having a competing supplier quote or documented SLA failures gives you leverage, like bringing a competing job offer to your salary review.
