Why does REDUVO Solo ask for a business number?
Because REDUVO Solo books for your professional activity, and your invoices are in your business's name.
Signing up happens entirely in the WhatsApp chat, in about a minute. Laure asks for your country, your name, your email address, whether you work through a company or are self-employed, the name to show on your invoices, then a business number.
The number asked for depends on your country and your status. Laure tells you which one at that step.
You finish by confirming this sentence: I confirm that I am booking for my professional activity, on behalf of my business.
