1. A method for managing usage of storage tank consumables in a storage tank, comprising:

  • receiving and storing by a central server comprising a processor and a storage device, measurements of storage tank consumables from a remote system associated with a storage tank;

    periodically calculating by the processor usage-based data for generating invoices for storage tank consumables based on sensor measurements representative of an estimated usage of the storage tank consumables;

    receiving and storing by the central server a fill value representing an actual usage reported to the central server when the storage tank is filled;

    reconciling the estimated usage with the actual usage by the processor by summing all estimated usages since a last fill of the storage tank, calculating a difference between the sum of the estimated usages and the fill value, and issuing a debit or credit based on the difference for reconciliation.
