Incumbent The supplier you're already using. Like your current phone carrier — switching feels hard, but staying costs more.
Price Creep Small, slow price increases that add up over time. Like a streaming service that raises its fee $1/month every year — barely noticeable, but expensive in the long run.
Amortized Spreading a one-time cost over several years. Like paying €120 for a yearly gym membership instead of €10/month — the upfront feels big but averages out to pennies a day.
Qualification The process of checking if a new supplier meets your standards (audits, certifications, testing). Like a background check before hiring someone — it costs time and money, but it prevents bigger problems.
Breakeven The point when the money you save from switching equals what you spent to make the switch. After that, every month is pure savings.
Market Rate Benchmarking Comparing your supplier's prices to what others in the market charge. Like checking prices on Amazon before buying at full retail — you can't know if a deal is fair without comparison.
