Add payment method for a unregistered business in italy

[Shoaib77]

So Im opening this business as a side hustle. After making website and all these, I just found out customers cant pay with visa, mastercard or other credit/debit cards except paypal.  When I tried to add a payment method provider, they're asking for the registration or VAT number. Strip is not available here.

Now if I go to register the company, it'll take a lot of time and money. I really dont want to face this hassle right now. And also I dont wanna put this much money and effort before seeing some returns. What can be the solution of this problem except registering the business?

Thanks in advance
