Price escalator
A contract sentence that changes the price on a schedule, by a fixed percent or by an index.
A price escalator is the clause that keeps a multi-year service fee from staying frozen while costs move. In commercial cleaning, landscaping, HVAC maintenance, security, and pest control it is usually a fixed percent once a year, a CPI adjustment, a wage pass-through, or a step that happens because the contract renewed.
The escalator is not the invoice. Billing systems such as QuickBooks, Aspire, Jobber, ServiceTitan, CleanGuru, and Swept store a number and repeat it. They do not read the clause. The work is to extract the sentence, compute the number it actually produces, and change the template only after a person approves it.
Read four things before any arithmetic: the base the percent applies to (the fee then in effect, or the original fee), the date it happens, whether notice is a condition, and whether a cap or a floor sits on top. Missing any of the four produces a confident wrong number.
A clause that is silent is not an escalator. Do not infer a 'standard 3%' because similar customers have one. The audit cites the words that are there and stops when they are not.
