    Integrating FastSpring with existing systems and third-party applications can be complex and may require technical expertise, which could be a barrier for some businesses.

  • Show HN: List of Stripe Alternatives
    Seems like every time there's a negative Stripe story on here, the inevitable question, "any alternatives?" gets asked. Hell, I was tempted to ask myself. Instead, I decided to search hn.algolia.com to see for myself what others have recommended in the past. Might as well share the list with y'all, make it meta. -- 2Checkout | https://www.2checkout.com Adyen | https://www.adyen.com Amazon Pay |... - Source: Hacker News / over 3 years ago
  • Update: Stripe is holding over $400k of mine with no explanation
    We had a great experience w/ Fastspring: https://fastspring.com/ It has been a few years though since we sold the company. Super easy to set up, super reliable. Never had any issues w/ them. - Source: Hacker News / over 3 years ago
  • Ask HN: What's your freelancing company/business setup?
    All of the below is no professional advice, Iโ€™m just a programmer who looked into this a bit. The easiest thing in my opinion would be to incorporate in Croatia and then use Paddle https://www.paddle.com/, Gumroad https://gumroad.com/ or FastSpring https://fastspring.com/ for payments. They take care of all your VAT/Sales taxes. If you want to go with a simple company outside of Croatia, maybe go with a UK Ltd,... - Source: Hacker News / over 3 years ago
  • Got an email from fastspring today saying my auto subscription to Premiumize was declined?
    Hi, I have been paying for Premiumize via paypal but today I get an email from fastspring.com saying an autopayment was declined. I have tried to "update my info" as it asks me to do but there is still an error? Source: over 4 years ago
  • Ask HN: SaaS Billing?
    FastSpring https://fastspring.com/ and Gumroad https://gumroad.com/ are two more alternatives to Paddle you can look into. Both handle VAT for you which makes global sales so much easier (worth it in my opinion for the higher rate you pay, but that depends on your project). - Source: Hacker News / over 4 years ago
