Stahls' Fulfill Engine has no monthly fee — it takes 3.5% of every webstore cart, or $0.50 per item on integrated orders, capped at $20 an order. Forever. PlatenFlow is $149/mo flat. Past a few hundred orders a month, the math stops favoring transaction fees pretty fast.
Stahls' "no monthly fee" pitch is real — if you do a handful of orders. As volume scales, you pay the percentage on every single one, and the bill grows with the shop. PlatenFlow's bill doesn't.

"Zero monthly" sounds free until you're paying it on every shirt that ships. The deeper issue isn't the math — it's that you don't own the stack you're running on.
At 100 orders/mo it's a wash. At 500 you're paying 4× the PlatenFlow flat fee. At 2,000 you're paying 18×. The successful shop pays the most.
