I m a solo dev about to sell a one-time-purchase macOS desktop app, and I ve been hunting for the right way to take payments and handle licensing. I wanted a merchant-of-record so I don t have to deal with global sales tax / EU VAT myself.My experience so far, in case it s useful to others going through this:- Lemon Squeezy: spent about a week integrating their API and testing the full purchase + license flow, and then got rejected during review with no explanation and no real path to ask why. A week of work to a dead end. Frustrating, and I still don t know what tripped it.- Polar.sh: Went with them after the LS rejection. Onboarding and developer experience have been great so far, though I ll be honest, I haven t pushed real volume through it yet, so I can t speak to payouts or support-under-pressure.- Paddle: keep hearing it recommended as the established MoR option. Haven t tried it. Is it worth the integration effort, or is it heavier than a solo shop needs? I m considering adding a 2nd payment processor I can easily switch over to just in case polar.sh changes their minds...- Gumroad anyone? Their fees are twice as much as compared to the others (10% vs. 5%, same $0.50 transaction fee though).I should also note that the review period on Lemon Squeezy took like 4 days until I got the rejection, whereas Polar.sh approved me with 2 minutes of submitting and verifying my identity. And they both used Stripe in the background for the verification; although Polar.sh s path via the Stripe verification took a few more steps; needed to take back and front photos of my drive license and then a selfie (presumably to match it up to the driver license photo. Lemon Squeeze didn t ask for any of those steps...So for those of you actually selling software:What did you settle on, and would you pick it again?For the MoR options (Paddle, Polar, FastSpring, Lemon Squeezy, etc.) — how s the reality vs. the pitch on tax handling, payout reliability, and support when something breaks?Anyone moved off one of these and why?Trying to make a decision I won t regret in a year. Thanks!
