About PayQuanta

Building realistic payment architectures for complex businesses.

PayQuanta is a worldwide payment gateway focused on institutions and merchants for whom payments are mission-critical – from PSPs and FX brokers to platforms, high-risk verticals and their banking and EMI partners.

Our role in the payment ecosystem.

We sit between merchants, PSPs, FX & trading companies, EMIs, banks and crypto service providers – making sure flows, responsibilities and expectations are clearly defined for everyone involved.

Technology gateway

A single technical layer over multiple acquirers, processors and payment methods, with routing tuned to real-world constraints.
  • Cards, APMs, bank transfers and crypto*
  • Routing by country, currency, BIN and risk profile
  • Fallback logic and resilience across providers

Operational backbone

Tools and processes that help finance, reconciliation, operations and risk teams run the payment business day by day.
  • Merchant and sub-merchant structures
  • Settlement, fee and reserve configurations
  • Exportable reporting for audit and finance

Solution designer

Advisory and hands-on work when positioning payment flows with banks, EMIs and crypto partners, especially in complex or high-risk verticals.
  • Realistic use-case and country mapping
  • Support preparing materials for partners
  • Iterative adjustments as your business evolves

How we think about payments.

Our starting point is not “what can we plug in technically?” but “what will your banks, EMIs, schemes and regulators accept over time?”.
1

Counterparty first

We design flows so that banks, EMIs and other partners can clearly understand the business model, risk controls and responsibilities.
2

Operational reality

We consider who reconciles, who monitors risk, who responds to chargebacks and which teams need which reports – then build accordingly.

Long-term relationships

Our goal is not a quick workaround, but an arrangement you can discuss with partners in risk, compliance, treasury and finance with confidence.

Who we work with.

PayQuanta works with institutions and businesses across regions where cross-border flows, complex verticals and regulatory scrutiny are part of daily life.
Payment service providers (PSPs) FX & trading companies Brokers & investment platforms Payment-intensive merchants & marketplaces EMIs & payment institutions Advisors, consultants & referral partners Businesses in high-risk or niche verticals

How we work with clients.

We prefer clear communication, realistic expectations and documented flows over promises that cannot be sustained in front of your partners.

Transparent & pragmatic

We are direct about what can be achieved given your verticals, countries and counterparties. If something is not realistic, we say so early.
  • Clear communication with all stakeholder groups
  • Documentation your teams can actually use
  • Iterative improvements instead of big surprises

Relationship-driven

We see ourselves as a long-term payment partner, not just a technical vendor. Our work is measured by the strength of your relationships with banks, EMIs and merchants.
  • Respect for partner risk appetite and constraints
  • Support for internal committees and decision makers
  • Focus on stability and scalability, not just speed

Leadership.

PayQuanta is led by operators who have built and scaled real-world payment infrastructures — not theory. Our leadership team comes from payment gateways, fintech platforms, FX and brokerage operations, European PSPs and crypto payment environments.
