Polar handles all your sales tax and VAT as your MOR, so you can just use it and focus on your business instead of tax hassles, while Stripe only becomes necessary once your SaaS startup hits $4–10M/ARR.
Only use Stripe if you're a venture-backed SaaS startup doing $4–10M/ARR+, otherwise just use Polar.
Polar takes all the sales tax and VAT compliance off your plate by acting as your Merchant of Record, so you don't have to worry about tax rules or filings. Stripe leaves that burden on you, which means you're responsible for handling all those compliance headaches yourself.
If you're a startup in the $1K–400K/MRR range and want to avoid the mess and distraction of tax compliance, Polar is the obvious pick. Stripe only becomes the better choice once you're a much larger, venture-backed SaaS and need its deeper infrastructure and integrations.
For most teams just looking to process payments without dealing with tax complexity, Polar is the one that actually saves you time and stress. Stripe is strong, but unless you're already at scale and ready to take on tax yourself, it just makes things harder.
