The 9% seller fee that turns "free" into paid
Beacons' free plan looks generous until you sell something. Every digital product sale through the free tier gives Beacons 9% off the top before you factor in Stripe's ~3%. On $500 of digital sales in a month, Beacons keeps $45; over a year that's $540, which is enough to have bought Store Pro ($30/mo, $360/yr) twice. The fee is the free tier's revenue model, and it's the exact mechanism that pushes serious sellers up to Store Pro.
