Crypto payment gateway: how much does it cost and how is it billed?
The two billing models
In the % per transaction model, you pay a slice of every sale — that's how cards work, through the MDR (the merchant discount rate).
In the fixed subscription model, you pay a monthly amount and receive as much as you want without paying per transaction.
Stackfy's model: a fixed subscription
Stackfy charges a monthly subscription, with no percentage per sale:
- Starter — R$97/month
- Pro — R$197/month (15-day free trial, no card)
- Business — R$397/month (full white-label, own domain)
It's non-custodial (the money lands straight in your wallet) and BRL-native (prices locked in reais).
When does a fixed subscription pay off?
The higher your volume, the more a fixed subscription beats a %: since the cost doesn't grow with sales, the per-transaction price drops as you bill more. In a % model, the cost rises with revenue — forever.
What's included
All plans include a ready-made checkout (Bitcoin and USDT), a dashboard, email and Telegram alerts, and the API. Business adds full white-label (your brand and domain). See the details on Plans.
Frequently asked questions
Does Stackfy charge a per-transaction fee?
No. The model is a fixed monthly subscription, so the cost is the same whether you receive R$10 or R$10k.
Is there a trial period?

Are prices in reais?
Yes. Stackfy is BRL-native: plans and charges are locked in reais, even while you receive in crypto.
