The decision, in plain words
For a solo builder at $5,000 monthly revenue and a $50.00/mo budget for the payment provider slot, Stripe leads at 33% fit and $196.60/mo. The two rules doing the work: ecosystem maturity (established — our estimate from ecosystem age, docs and hiring pool); batteries included (Bundles usage-based billing — fewer services to glue at team size 1).
Polar runs close (29% fit, $278.80/mo). It takes the lead if bundles tax handled, license keys, usage-based billing — fewer services to glue at team size 1 matters more to you than the current weights assume.
Honest weak spot of the pick: ~$196.6/mo is 393% of your $50/mo budget — over it.
