What it costs you — and what you gain

Trade-offs a CTO or CEO must make — translated into lost revenue and compliance risk.

Without structured support

  • PSP vendor lock-in

    Single processor, impossible migration, subscribers lost on switch

  • Wrongly refused revenue

    No cascading, failed transactions without smart retry

  • Opaque compliance

    PCI-DSS, PSD2, 3DS — costly audits, poorly scoped PCI

  • Drifting PSP costs

    No cost-based routing, unoptimized interchange fees

With JST6 pipeline

  • PSP independence

    Vault + tokens — switch processor without friction

  • Revenue saved

    +5 to +15% via smart routing & failover

  • Compliance by design

    Scoped PCI-DSS, webhooks & audit trail

  • Controlled costs

    Multi-PSP routing by cost and availability

Field proof

Orchestration and gateway delivered in FinTech prod — not generic slides.

Payment under the iASSET framework

  • Versioned spec before any PSP change
  • Security & compliance gates on every merge
  • Cost/acceptance rate monitoring in prod
iASSET method

15 minutes to scope your payment

We'll identify whether the lever is an audit, a targeted orchestration or a full AEP workshop.
