E-invoicing solutions for
Energy & utilities
Thousands of invoices a month, complex internal structures, strict legislation and diverse customers: in the energy sector, every link counts. One mistake in your billing process can lead to complaints, delays or audit problems. Yet many utilities still cling to manual controls and outdated flows.
With e-invoicing through Nymus, you bring structure and reliability to that process without upending your ERP.

E-invoicing challenges
Do you recognize yourself in these situations?
As an energy or utility company, you work with diverse customers, suppliers, and internal teams. Every billing process has to be right: for the public, the government, AND your own audit trail. But your systems are often fragmented, and every exception takes time.
Large volumes, often with anomalous flows
Invoices to citizens, businesses, governments or partners each run differently. One mistake means delays in payment or customer complaints.
Legal obligations are changing rapidly
From ViDA to e-reporting to Peppol. You have to meet increasingly stringent requirements. Manually, it's hard to keep up.
Internal complexity between entities
Multiple departments, legal structures or subsidiaries unnecessarily complicate invoice processing, especially in the case of mutual reinvoicing.
Suppliers each use their own format
Some send Peppol, others scan a pdf. Your team has to figure out what belongs to which service each time, and that takes time.
