SaaS based in Finland, customers potentially from anywhere. Question about taxes
I am building a SaaS and was thinking of using Stripe's hosted Checkout and the new Customer portal since this would save me a lot of time from building everything myself, and I could launch earlier. However my understanding is that Stripe doesn't do anything about taxes, so I have to take care of that myself. I know that there are some partner services like Octobat that calculate taxes and integrate with Stripe, but if I understood correctly this isn't enough. I have learnt that you have to file and pay taxes to authorities in various countries. Some countries have thresholds, others don't. Countries like India even require to register in the country before doing any business there. It sounds like a mess to me...
I'm based in Finland, so in the EU. What should I do to accept payments from anywhere and be tax-compliant with every country?
I found a few services like Paddle that seem to handle everything for me and act as resellers/merchant of record. They do everything about taxes and I don't have to do anything at all. However my SaaS is a CMS that lets users create their sites and Paddle's AUP (https://paddle.com/support/aup/) says mentions web hosting services as potentially not supported/allowed. I have sent a message asking if my SaaS would be considered hosting but I haven't received any reply.
Are there other options I should be looking into? Generally speaking - for those of you who have a SaaS based in the EU - which payment solution did you go for and how do you manage taxes in the various countries if you don't use something like Paddle?
Thanks a lot in advance for any help!
