Nuvvola

Good morning, I am a Graphic Design and only provide digital services. I work with clients from other UE / extra-UE countries that are both private customers and entrepreneurs with VAT-id. But I expect to earn less than 20k per year, so I will apply for the Small Business Scheme. My question is: do I still need to file the VAT return? I read contrasting articles about it. For instance, using the tool named "Ik lever diensten in en uit het buitenland – wat doe ik vanaf 1 juli 2021 met de btw?" it says that I shouldn't file or charge VAT. But then I read an article about foreign services and it stated the following: "Wanneer je buitenlandse klanten hebt of transacties doet waarbij de btw is verlegd, dan moet je toch aangifte omzetbelasting doen. Ga dan na of de KOR al dan niet interessant voor je is." Can you help me figure it out?
