Split billing and CREG tariffs

With split billing an employee charges their company car at home at their own charge point, and the employer pays for those charging sessions. Wattify measures the sessions, invoices the employer and pays out the employee. This article explains how that works and what you set.

#How it works

1. The employee has a charge point at home that is connected to Wattify, with a charge card for the company car.
2. Every charging session is registered on the charge site of the employee.
3. Once a month Wattify invoices the employer for all the sessions of their employees together.
4. As soon as the employer has paid, Wattify pays out the employee through a refund note, to the IBAN in their profile.

Split billing therefore requires two accounts: an employer account and an own account per employee, each with its own sign-in details. The Split billing subscription costs 5 euro per month per charge site, with monthly settlement and an annual summary.

#Setting up split billing

On the dashboard go to Wizard in the left-hand menu, click Start and go through the steps. In the last step:

• Are you signed in as an employer? Then you do not have to choose an employer: the charge site is linked to your account automatically.
• Are you an installer? Then choose an existing employer or create a new one.

The wizard creates the charge site, the charge point and the accounts of the employer and the employee. You will find the remaining steps in Registering a new charge site.

#The CREG tariff

The CREG (Commission for Electricity and Gas Regulation) publishes the average electricity price for households every month, around the middle of the month. That figure includes VAT (6%), transport and distribution, and starts from an annual consumption of 8,000 kWh, which includes one electric car. There are separate figures per region (Flanders, Brussels, Wallonia) and per type of meter (digital or classic).

Wattify adopts those tariffs automatically. You can always see the most recent CREG prices on your dashboard. An employee may well have a more expensive or a cheaper energy contract; the CREG tariff is an average that serves as a cost-covering basis. Anyone who regularly runs the VREG's V-test can switch to a contract with better terms.

#Regional or federal

Since 2025 an employer may calculate the reimbursement in three ways, each time as a maximum amount:

You record the choice between regional and federal in the portal and keep it for the whole calendar year. If you do not make a choice, the regional tariff applies. Record your policy on the reimbursement of home charging in your company's car policy as well; your social secretariat can help you with that.

#Setting the CREG tariff on a charge site

Open the charge site of the employee, tab Price setting, and under CREG tariff choose at Rate either Regional CREG rate or Federal CREG rate. On charge sites with the subscription for employees' home charge points the CREG tariff is always on; Off only exists for the Public subscription. You can read more about how the price is built up in Setting your prices.

Do you want to give one particular charge card the CREG tariff on a charge site that has a different tariff itself, the company car of an employee at the charge point of the business for example? You do that with a CREG discount on that charge card; see Linking charge cards and giving a preferential tariff.

#Settling on the actual cost

Does the final settlement of the energy supplier show that the employee paid more or less than the CREG tariff? Then Wattify can recalculate a period on the basis of their actual price per kWh. To do so you divide the total amount of the energy invoice (including 6% VAT) by the total consumption in kWh. The difference with what has already been paid out is corrected in a separate settlement; the employer and the employee both receive a pdf of it. This settlement is without obligation and does not lead to extra Wattify invoices. Contact support@wattify.be for it, with the start date, the end date and the price per kWh from the energy invoice.

#The payout of the employee

• Employers see all invoices and their status under Invoices. The status is updated at least once a day.
• As soon as the invoice of the employer has been paid, the linked payouts of the employees jump from Unpaid to To pay out. Wattify processes payouts at least once a week, normally on Monday.
• If a payout is on Paid, the amount has been transferred to the IBAN stated with the payout.
• Without an IBAN in the profile of the employee, Wattify cannot pay out. The employee then receives a weekly reminder by e-mail to fill it in. See Your profile and billing details.

#Letting somebody else charge at a split billing charge point

Do you want your partner or a housemate with a company car from another employer to charge at the same charge point? That is possible in two ways.

The other employer becomes a Wattify client themselves. That employer sends their billing details to support@wattify.be. Wattify creates a client account, after which that employer adds charge cards. Those cards work on the existing charge point straight away. Both employers only see their own sessions and are invoiced separately on the same terms.

The other employer does not want to become a client. Then you make the charge point semi-public: public charge cards (Shell, TotalEnergies, Eneco, and so on) are then accepted. Wattify settles with the issuer of the charge card, who in turn settles with the employer. The price Wattify charges is the same for every party; the charge card issuer may add its own margin on top. Mail support@wattify.be to have your charge point set to semi-public; Wattify first carries out a few checks.

A semi-public charge point is passed on to the charge card issuers. Some issuers show it in their app anyway, even though Wattify asks them not to; there is nothing Wattify can do about that.
