If you're a business customer, adding your VAT or tax registration number ensures your invoices are issued correctly - including applying reverse-charge rules where applicable.
Before You Start
Make sure you have:
Your VAT or tax registration number
Access to the email address linked to your Fyxer subscription
Tax details are managed through Fyxer's secure billing provider (Stripe).
Add or Update Your VAT / Tax ID
Open the Stripe Billing Portal
Use the billing link provided by Fyxer, or the portal link shown in Dashboard → Settings → Billing.
Enter your Fyxer account email
This must match the email associated with your subscription.
Check your inbox for a login link
Open the email from Stripe and click the link to access your billing profile.
Go to Billing Information
Select Update information.
Scroll to the VAT / Tax ID field
Enter your VAT or tax registration number.
Click Save to apply your changes
When the VAT / Tax ID Takes Effect
Your VAT or tax ID will be applied from your next invoice
Changes are not applied retroactively to past invoices
You can see your current billing cycle dates at the top of the Stripe portal
Common Questions
Why don't I see VAT removed immediately?
Tax changes apply from the next billing period, not existing invoices.
What if I enter the wrong number?
You can return to the Stripe portal at any time to update it.
Do I need to contact support after adding my VAT ID?
No - once saved, the change is applied automatically.
