Worked examples on a $50 sale. Compare to a typical card processor at 2.9% + $0.30 → you'd keep $48.25. EpochPay's bank, stablecoin, and Lightning rails are all cheaper than card.

Dedicated quantum-compute capacity on IBM Heron.
If you want quantum-compute throughput (not payments, not the developer SDK), these tiers reserve IBM Heron processor time with our pipeline-parallelism and error-mitigation layers on top. For most buyers this isn't what you want; click I want to take payments above for the rail.
Per-tier QSWT overage available; talk to partners@epochpay.today for a quote and reserved-capacity contracts.
