Corporate invoicing
You can take care of your company’s electricity invoices conveniently with an e-invoice, online invoice or collective invoice.
Value added tax will increase from 24 per cent to 25.5 per cent on 1 September 2024, which will also affect Oomi’s prices for electricity contracts and services. As the increase comes into force, companies obligated to pay value added tax must take the new VAT into consideration in their operations.
E-invoice
An e-invoice is a secure method developed by banks for receiving and paying invoices. You can subscribe to e-invoices even before the first electricity invoice. In the contract confirmation, we will provide you with an invoicing ID that you can use to authorise e-invoicing in your online bank.
