SendOwl charges a flat monthly fee — and then caps how much you can earn before forcing you onto a more expensive plan. Two fees for the price of one. Payhook charges $0/month, has no revenue cap, no order cap, and a full write API.
SendOwl's pricing looks simple until you hit a cap. Each plan limits annual sales volume — exceed it and you're automatically upgraded. Here's what it actually costs at different revenue levels:
| Monthly revenue | SendOwl fee | Payhook fee | Difference |
|---|---|---|---|
| $500/mo | $39/mo (Launch — nearing cap) | $14.50 (Stripe only) | $24.50/mo |
| $1,000/mo | $87/mo (forced onto Grow¹) | $29.00 (Stripe only) | $58/mo |
| $3,000/mo | $87/mo (Grow) | $87.00 (Stripe only) | $0 |
| $5,000/mo | $159/mo (forced onto Scale²) | $145.00 (Stripe only) | -$14/mo |
¹ $1k/month = $12k/year — exceeds Launch plan's $10k/year sales cap. Auto-upgraded to Grow ($87/mo).
² $5k/month = $60k/year — exceeds Grow plan's $36k/year sales cap. Auto-upgraded to Scale ($159/mo).
