Dynamic product use reporting system

A product monitoring method comprising:

• receiving, at a data processing system, a refill alert indicating that a product dispenser is being refilled with a first roll in a primary roll holder;
• determining, at the data processing system, a stub roll size based on a number of dispenses of the product dispenser between a time of the refill alert and a time of a low product alert indicating that the amount of the first roll is in a threshold range;
• setting, at the data processing system, a size of a second roll in a stub roll holder as the stub roll size, wherein the first roll is the second roll when moved to the stub roll holder;
• determining, at the data processing system, an expected depletion date for the first and second rolls based on the stub roll size and a size of the first roll in the primary roll holder;
• receiving, at the data processing system, reports of the numbers of dispenses of the product dispenser according to a reporting schedule;
• and
• adjusting, at the data processing system, the reporting schedule to increase the frequency of reports in response to determining that the numbers of dispenses exceeds a threshold.
