SaaS Startup FAQ
Where is the best place to incorporate a SaaS startup?
Delaware (USA) is the gold standard if you plan to raise venture capital. For bootstrapped founders, Estonia (OÜ) or the UK (LTD) offer great digital infrastructure and tax efficiency.
Do I need to charge VAT/Sales Tax to global customers?
Yes, most jurisdictions require you to collect VAT or Sales Tax based on the customer's location, even if your company is based elsewhere. Using a Merchant of Record (MoR) can simplify this.
How do I accept recurring payments?
You need a business bank account and a payment gateway like Stripe, or a Merchant of Record like Paddle or Lemon Squeezy. These services require your company to be incorporated in a supported country.
