The visible processing fee is only one part of payment acceptance cost. A business should compare the full operating model: successful payments, refunds, fiscal requirements, integration work, reporting and support effort.
This article does not publish MulenPay pricing. For commercial discussion, use payment acceptance; the goal here is to explain how to compare offers.
A sample cost model, not a universal formula
Total cost may include successful transaction fees, refund handling, fiscal receipt requirements, integration effort and operational losses from failed payments. Not every element applies to every merchant.
What a percentage fee does not show
The same percentage can mean different economics for a low-ticket store and a high-ticket education platform. Refund workflow, support time and reconciliation can matter as much as the rate itself.
| Cost element | Impact | Question to ask |
|---|---|---|
| Processing fee | affects margin on each successful payment | what is included |
| Refunds | create support and reconciliation work | how the process works |
| Fiscal receipts | add compliance and data requirements | how receipts link to orders |
| Integration | requires development and testing | which connection method is available |
A calculation example without invented rates
Use your own average order value, successful payment count, refund share and support time. Even without provider-specific rates, this shows which cost driver matters most.
How to compare providers
- Compare the same payment scenario.
- Separate card payments, links and subscriptions.
- Check reporting and status visibility.
- Review fiscal receipts if receipts matter.
Conclusion
Pricing should be evaluated through process economics, not only through a percentage. For card scenarios, also review card payments.

FAQ
Why is the fee not the full cost?
Refunds, receipts, integration, support and reconciliation can also affect the real cost.
Can pricing be compared without average order value?
Only roughly. A useful comparison needs order value, volume and refund share.
Do all cost elements apply to every merchant?
No. The model is approximate and depends on the payment scenario.
Where should commercial terms be checked?
On product pages and in agreed provider terms, not in an informational article.
