Dynamic product use reporting system

1. A product monitoring method comprising:

receiving a refill alert indicating that a first roll in a primary roll holder has been removed or a housing holding the first roll has been opened;

determining a stub roll size, by a data processing system, based on a difference between a number of dispenses available from the first roll at a time of a low product alert and a number of dispenses available from the first roll at a time of the refill alert; wherein the low product alert indicate that the amount of the first roll is in a threshold range;

setting, by 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 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 reports of the numbers of dispenses of the product dispenser according to a reporting schedule;

adjusting, by the data processing system, the expected depletion date based on the reports of the numbers of dispenses; and

adjusting, by 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.

2. The method of claim 1 , wherein adjusting the expected depletion date comprises adjusting the expected depletion date based on monitoring foot traffic in an area of the product dispenser.

3. The method of claim 1 , wherein the product dispenser dispenses from the second roll until depleted before dispensing from the first roll.

4. The method of claim 1 comprising maintaining the reporting schedule in response to determining that the numbers of dispenses does not exceed the threshold.

5. The method of claim 1 , wherein determining a stub roll size comprises accessing data describing a predetermined number of dispenses available from the first roll.

6. The method of claim 1 comprising resetting the reporting schedule to an initial state in response to receiving the refill alert.

7. The method of claim 1 comprising generating a dispensing profile based on the expected depletion date and the numbers of dispenses, wherein the dispenser profile indicates a time-varying number of dispenses over a set period.

8. The method of claim 1 comprising adjusting the reporting schedule to align with maintenance visits to the product dispenser.

9. A product monitoring method comprising:

receiving, at a data processing system, a refill alert indicating a first roll in a primary roll holder has been removed or a housing holding the first roll has been opened;

determining, at the data processing system, a stub roll size based on a number of dispenses available from the first roll at a time of a low product alert and a number of dispenses available from the first roll at a time of the refill alert;

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.
