Who can apply for a professional account?
A professional account is intended only for individuals who work professionally as glass artists, teach or operate a studio professionally. Hobbyists are not eligible.
We verify that the applicant is effectively professionally active, including through the VAT number, trade number or other supporting documents proving professional activity.
1. Become a customer
Requesting a professional account is only possible for existing customers. Thus, you must have placed an initial order before your professional account can be activated. The amount of this first order counts to calculate your annual discount*.

This can only be done by email to info@biss-glass.eu
List the following data:
- company name
- name of contact person
- billing address
- VAT number / company number
- phone number
- brief description of your activities (studio/art discipline …)
3. Approval of your professional account
Once your company number has been checked and approved, your account will be adjusted and you can enjoy discounts. The discounts are calculated based on the total amount of orders already placed.
At the end of December, the discount rate for the following year is awarded.
4. Log in and place your order
Once you log in, you will see the adjusted prices.
You will receive a pro forma invoice in your account page. The official invoice will be sent to you by email or via the Peppol system.
*How does the annual discount work?
Customized discount: The discount is customized and is based on the previous year’s total purchases.
With a PRO ACCOUNT you will always enjoy adjusted prices and benefits, but also an extra percentage discount, based on the annual purchase amount. The percentage may vary depending on the purchase amount. The more you spent in the previous year, the higher the discount will be. On Jan. 1, the new discount rate is automatically applied.
