Who uses GetMyInvoices with Power Watt Energy Island

Electricity & Gas Providers
At the end of the month, many energy providers accumulate dozens of billing documents from the Energy Island account, scattered across multiple inboxes and folders, while accounting simultaneously has to reconcile tariff billing with actual procurement costs. If even a single energy procurement receipt is missing, the entire reconciliation is delayed and the VAT advance return slips through at the last minute. With GetMyInvoices, all invoices and billing data from Power Watt Energy Island are automatically retrieved and forwarded directly to accounting. This creates a complete set of receipts without anyone having to manually add missing documents or remind colleagues about outstanding paperwork.

Municipal Utilities
A municipal utility that distributes or resells electricity locally via Power Watt Energy Island regularly receives billing statements for grid feed-in and consumption balancing, which often need to be searched for in the finance department before account reconciliation can begin. Especially with multiple feed-in and consumption points, it's easy to lose track of which billing has already been recorded and which is still missing. GetMyInvoices automatically downloads these documents from the portal and makes them available to the responsible team, so that no duplicate retrievals or forgotten invoices delay reconciliation any longer. This creates a reliable foundation for bank reconciliation, without anyone having to chase after portal access credentials.

Charging Infrastructure & E-Mobility
Operators of charging infrastructure who source electricity from Power Watt Energy Island's generation pool often receive their invoices on a usage basis and at irregular intervals, which makes monthly cost allocation to individual charging locations more difficult. If these receipts arrive late or are scattered, the basis for correctly allocating consumption costs to the respective locations is missing at the end of the month. With GetMyInvoices, new documents are automatically detected and downloaded, ensuring that all consumption bills are reliably and completely available. This allows cost allocation per charging point to be completed promptly, without having to wait for delayed receipts.
