Registering the FlexiObox to your business

It is possible to register the FlexiObox to your business instead of you as a private person.

To do this, you need to contact our helpdesk and provide your VAT number. From then on, we will bill your company instead of you as a private person.

By registering as a business, you agree to use self billing for earnings generated by grid balancing.

Implications for your business

  • FlexiO has a monthly subscription cost,

  • and, once your installation is part of our digital power plant, monthly earnings for grid balancing.

So you will pay us money (and register that as a cost), and receive money from us (and register that as revenue).

Taxes on FlexiO earnings

The grid balancing earnings you make as a company are taxable. If you are a private person, they are not taxable, as the tax administration in Belgium considers this small income as a normal part of normal management of your PV and battery installation, and not an economic activity. But this exception only applies to private persons.

We will not support billing the subscription to a company and the earnings to a private person.

Invoices

The subscription invoice is like any other invoice your receive: we create the invoice and send it to your company.

The earnings invoice is different: because your company is providing a service to us (grid balancing), your company should create the invoice, with the exact amount you are going to receive. But to simplify the administration, we will create a self bill for your company. You can enter it in your bookkeeping like any other invoice you created.

VAT on your energy tariff

Because your energy contract is probably also registered to your company, you will deduct the VAT paid. This means the consumption cost FlexiO calculates should not include the VAT. Contact our helpdesk or your installer to change the VAT in the calculation to zero.

If the electricity is also provided to an employee as a benefit in kind, the VAT you can deduct might not be the full VAT paid. Check this with your accountant and let us know the actual rate.

Self billing details

Self billing means we (the receiver of the services) will create the invoice instead of your company (the supplier of the services).

The invoice will have a unique prefix, so they do not conflict with other invoices you create. E.g. LP/INV/2025/0004 will be the fourth invoice we create for you in the year 2025. The numbers will be sequential for you: LP/INV/2025/0001, LP/INV/2025/0002, LP/INV/2025/0003, …

21% VAT will be added to the invoice, which you will need to include in your regular VAT statements. So if your installation generated 20 EUR in earnings, the bill will have a total amount of 24,20 EUR, and you will be paid 24,20 EUR by us.

The invoices will be generated one month after the month when grid balancing happened, but the payment date will be three months after the month when grid balancing happened, just like our earnings payouts to private customers.

Example:

  • Grid balancing in January

  • Self bill created in February, with payment date April

  • Payment in April

Agreeing or contesting self bills

As we generate the invoice, you have the right to contest it. You can do so by contacting our helpdesk. If we did not receive a contest from you in the month following the creation of the invoice, we assume you agree to it.

Transitional measures 2024-2025

We will start self billing for all earnings generated in 2025. Earnings before this date will not get a self bill from us, even if they are paid out in 2025.

This means that in February and March 2025 we will send out self bills for earnings generated in January and February, but we will also send out the payments for earnings generated in November and December 2024.
