We attempt to provide reasonable price increases for renewal contracts, typically inflation rate plus 1% per year, for the incremental value that we add to our products. In addition, at the time of initial purchase, we offer customers the option to purchase a price lock-in. This limits the maximum price increase to 3% per year. Purchased on a 3 year contract it will cover the 2 years following that term. For clarity, this 3% annual increase limits the total increase in price for year 4 to 9% (3 years at 3% per year).
