How do I set up split-billing for my employee's home charge point? (step by step)

Who is this subscription for?

The Employee home charging station subscription (split-billing) is there for employers: in one go you create an account for yourself as the employer and for your employee(s). Your employee charges their company car at home on their own charge point, Wattify measures every charging session, invoices you as the employer once a month at the CREG rate and automatically reimburses your employee on their own account. That way nobody has to keep receipts or meter readings any more.

This article walks you through the complete installation, from the button on the pricing page to creating an extra charge card. Allow about fifteen minutes, plus the time to enter Wattify's address in the charge point's app.

What do you need?

• Your company details: company name, email address, VAT number, IBAN and the billing address. The VAT number is checked live in the European VIES register. Are you exempt from VAT (as a home nurse, for example)? Then tick Vrije beroep (liberal profession).
• Your employee's details: name, email address and the IBAN the reimbursement has to be paid into. Usually that is their private account. Each party needs its own email address; the employee's address may not be the same as the employer's.
• The address where the charge point stands, so your employee's home address.
• The serial number of the charge point (on the unit itself or in the manufacturer's app) and access to that app or to the installer portal, to enter Wattify's address there.
• If you already have a charge card: the RFID code of that card.

You can interrupt the wizard at any time: at the bottom is the Copy link to continue later button. That link takes you back to the steps you filled in and stays valid for ninety days.

Step 1. Start on the pricing page

Go to wattify.be/nl/prijzen and click Start today in the Split-billing (AC) card. You do not need to create an account beforehand: the button opens the wizard straight away, and the accounts are created in the wizard itself.

The wizard has four steps: Charge site, Account, Charge point and Charge card. The bar at the top shows how far along you are. At the top of every step a reminder shows which subscription you chose, with a link to the pricing page.

Step 2. Charge site: name and address of the home charge point

A charge site is the place where the charge point stands: here, your employee's house.

• Name: a recognisable name for the charge site, for example "Home charge point Peeters". Every name is unique on the platform.
• Street, House number, Postal code, City of and Country: your employee's home address.

As soon as the address is complete, the wizard looks it up and places a pin on the Charge site location map. If the pin is not on the driveway or the garage, move it: the pin determines the exact GPS location of the charge point, the address itself does not change because of it. Then click Next.

Step 3. Account: employer and employee

In this step the wizard registers both parties, so that both the employer and the employee get their own account to follow up charging sessions, invoices and payouts.

Employer data are the billing details for the monthly CREG settlement:

• Company name and Email: the email address becomes the login of the employer account and receives the invoices.
• VAT number: is checked in the VIES register. Exempt from VAT? Tick Vrije beroep (liberal profession) and the field is no longer mandatory.
• Iban number: the account of the business.
• Billing email: only fill this in if the invoices have to go to a different address than the email address above, to the accounting department for example.
• Billing address: the address of your company as it has to appear on the invoice.

The Select employer dropdown at the top is only for installers and resellers who fill in the wizard for an existing customer; as an employer you leave it empty.

Then unfold Employee data. These are the details for the automatic reimbursement:

• Name and Email of the employee. At that email address they receive their own login.
• Iban number: the account into which Wattify reimburses the home charging sessions, usually their private account. You may leave the field empty; the employee can fill it in later in their profile, but without an IBAN no payout can be made.

Have you registered this employee before, for another charge point for example? Then choose them under Select existing employee; their details are then taken over.

Are you the business owner and do you charge at home yourself? Then tick The employee is the business owner. You keep one login (the employer account); the employee account for the reimbursement automatically gets a derived email address (your own address with +employee in front of it, for example name+employee@company.be) and no password of its own. Fill in your name and your private account; these appear on the refund note. You adjust the name and the account number later under Users.

Click Next.

Step 4. Charge point: serial number, setting the OCPP URL and testing

Now you link the charge point to Wattify. On the left you fill in the charge point, on the right is what you have to set in the manufacturer's app.

• Charging station brand: choose the brand (Zaptec, Easee, Wallbox, Alfen, Smappee, …). Is your brand not listed? Then choose Other: every charge point that supports OCPP 1.6 works with Wattify.
• Serial number / Device ID: the number on the charge point or in the manufacturer's app. For some brands the wizard automatically adjusts the spelling to what the charge point itself reports (Zaptec in lower case, for example). Copy the number exactly, including the letters: the charge point and the platform have to use the same number.
• Charging station description: a short, unique name by which you recognise the charge point, for example "Driveway at home". The wizard fills in a suggestion itself that you may overwrite.

The Connect your charging station block holds Wattify's OCPP URL, with a copy button next to it. As soon as you have filled in the brand and the serial number, that URL is adjusted to your charge point: for most brands it is wss://cpo.wattify.be/ocpp/ followed by the serial number. Now open the manufacturer's app or installer portal, choose "Wattify" there if that option exists, or paste the URL into the field for the OCPP server (sometimes called "back-end", "CPO" or "charging station management system") and save. How this works per brand is explained in the manual under Connecting your charge point to Wattify.

Then click Test the connection. The wizard first asks whether you have set the URL in the manufacturer's app; confirm with Confirm.

Wattify then checks whether your charge point has reported in with that serial number over the last few minutes. There are two outcomes:

• Connection failed: the charge point has not reported in yet. The notification repeats the expected OCPP URL. Check whether the URL is complete and correct in the app, whether the serial number in the wizard matches the one of the charge point letter for letter, and whether the charge point has internet (Wi-Fi, 4G or cable). Some charge points need a restart and a minute after saving. Then test again.
• Connected: the charge point is talking to Wattify. If the charge point reports in under a slightly different spelling, the wizard immediately adjusts the serial number and the URL accordingly; you see that in the notification.

Does the test not work straight away? You can still continue: you can finish the connection later, and the charge point appears as Online under Charge points as soon as it reports in. Click Next.

Step 5. Charge card

With a charge card your employee starts a charging session on their home charge point. The billing hangs on that card: every session with this card is invoiced to you as the employer and reimbursed to the employee.

Click Add another charge card and fill in:

• Name: the wizard suggests "Charge card" plus the name of your employee. Choose something by which you recognise the card in the platform and in the app.
• RFID: the unique code of the card. You find it on the card itself or with your supplier; it is what the charge point reads out when the card is tapped. An RFID code consists only of digits and the letters A to F; the wizard warns you if you type anything else. Each code can be linked to one card only.
• License plate: the number plate of the company car (optional).

Does your employee not have a charge card yet? Then leave the list empty. You create a charge card later in the portal (see below), or you request one from Wattify or from your installer. How to read out the RFID code of a card is explained in Learning mode and RFID codes.

Step 6. Finishing up and activating your account

Click Complete onboarding. Wattify now creates the charge site, the charge point, the charge card and the two accounts.

Both the employer and the employee receive an email within a few minutes with the subject Complete your account. Click Choose your password, choose a password and you are logged in at mijn.wattify.be. The link in the email is valid for seven days; after that you request a new one via Forgot password? on the login page. Received nothing? Check your spam folder.

If you chose the business owner option, you only receive the email for the employer account: that account also sees the charge site, the charging sessions and the payouts of the derived employee account.

After the wizard: your dashboard as the employer

After logging in you land on your dashboard. The Set up your account checklist shows what is still missing:

• Sign the contract: every charge site comes with a management agreement. Click Sign, read the agreement, accept it and put down your signature. You receive the signed agreement as a PDF by email. Wattify may not allow charging sessions on a charge site without a signed agreement, so do this straight away. The agreement of a home charge point is signed by the employer, not by the employee.
• Activate direct debit (recommended): with a direct debit your monthly invoice is paid automatically, and the reimbursement to your employee goes faster.

On the right of the dashboard you find the CREG rate of the month and the consumption overview of your charge sites.

Under Users you see yourself as Employer and your employee as Employee. That is also where you later adjust their name or account number, and with New user you add a next employee.

Checking the CREG rate of the charge site

On a charge site with this subscription the kWh price automatically follows the CREG rate: the average electricity price for households that the federal energy regulator publishes every month. Open Charge sites, click the charge site and go to the Price setting tab. Under CREG tariff you choose:

• Regional CREG rate: the rate of the region the charge point is located in (Flanders, Brussels or Wallonia). This is the default.
• Federal CREG rate: the lowest of the three regional rates, the same for all your employees, wherever they live.

The KWh fee shows the rate of this moment. Keep to the chosen basis (regional or federal) for the whole calendar year and lay it down in your car policy as well. More explanation about the rates and about the rules since 2025 can be found in the other articles of this category.

Creating an extra charge card

A second car, a lost card, or an employee who did not have a card yet in the wizard? Open Charge cards and click Create a charging card.

In the Type of charging card step choose Employee with a home charging point: charging at work and at home, whereby the home charging sessions are invoiced to you via split-billing. The other types are Employee without a home charging point (charges only on your charge sites) and Whitelisted private charging card (for the private car of the employee on their own charge point; those sessions are not invoiced to the employer). Click Next.

In the Data step you choose the Employee the card is for and you fill in the Name, the RFID code and optionally the License plate. Click Create.

The Note! window summarises what the card does: charging sessions with this card on the charge point of an employee are charged to the employer, in order to pay out the employee. Confirm with I understand, create. The card is in the list straight away and is Active; the employee can use it immediately.

You block a card (loss, employee leaving the company) via Edit, the Settings tab, switching Active off.

What your employee sees

Your employee logs in with their own email address and sees only their own charge site, charge point, charge cards and charging sessions. Two things are important for them:

• Their IBAN. Under their name at the top right, Profile, the Customer data tab, under Billing data is the Iban number they are reimbursed on. If no account has been entered yet, Wattify reminds them of it weekly by email; without an IBAN no payout can be made.
• Payouts. Under Payouts they follow up every refund note and its status. The overview is empty until the first month has been invoiced.

How do the invoicing and the reimbursement work?

1. Every charging session on the home charge point is registered at the CREG rate of that month.
2. Once a month Wattify invoices you as the employer for all home charging sessions of your employees together, plus the surcharge of 0,02 euro per kWh and the subscription of 5 euro per month per charge site (prices excluding VAT). You find the invoice under Invoices; the status is updated at least once a day.
3. As soon as your invoice is paid, the linked payouts of your employees jump from Unpaid to To pay out. Wattify pays out at least once a week, normally on Monday, to the IBAN from the profile of the employee.
4. Is a payout set to Paid? Then the amount has been transferred. The employee receives a note for every reimbursement.

Did your employee pay more or less than the CREG rate according to their energy bill? Then Wattify can recalculate a period on the basis of their actual price per kWh; see the article about settling at the actual rates.

Good to know

• Several employees? Go through the wizard again from the pricing page for each home charge point, or start it from your dashboard with Choose a subscription in the Split-billing charge point add for employee block. If you are logged in as the employer, your company details are already filled in and you only have to add the employee and the charge point.
• Installer or reseller? Start the wizard from your own account. In the Account step you then choose an existing employer under Select employer, or you fill in a new one. The employer and the employee each receive their activation email.
• Private charging on the same charge point? Create a Whitelisted private charging card for the private car: those sessions are not invoiced to the employer.
• A partner with a company car from another employer? That is possible on this charge point as well; read the article about opening up your split-billing to fellow residents.
• Does the charge point stay offline? Compare the serial number in the portal letter for letter with the one in the manufacturer's app, check the internet connection of the charge point and try the unsecured address ws://cpo.wattify.be/ocpp if the charge point has older software. If you cannot work it out, email the brand, model and serial number to support@wattify.be.
