Organizations must:

• Have proven experience providing card transaction processing or VisaNet/card-scheme connectivity services.
• Have provided such services in South Africa or to South African-regulated financial institutions.
• Have completed similar implementations in the past 5 years with verifiable references.
• Clarify their role (direct processor, reseller, integrator, aggregator, technology partner, or subcontractor) and identify any material third parties.
• Hold relevant regulatory scheme, PCI DSS, information security, and data-protection compliance.
• Demonstrate operational readiness including support model, service desk, monitoring, business continuity, and disaster recovery.
• Provide at least two client references for similar work.
• Confirm experience integrating with an existing financial transaction switch (not replacing it).
• Confirm service can be delivered without changing Postbank's current ACH clearing and settlement arrangement with PayInc.

• Postbank seeks a processing provider to enable VisaNet transaction visibility for debit card transactions.

• Required outcome: Enable transaction visibility through VisaNet while PayInc continues as the ACH for clearing and settlement. The processor’s role is visibility, monitoring and reporting, not duplicate authorisation, clearing or settlement.

• How long have you provided these services in South Africa or to South African-regulated financial institutions?
• List similar implementations in the past five years (country, institution type, service scope, go-live date, current status).
• Confirm if your organisation is a direct processor, reseller, integrator, aggregator, technology partner or subcontractor.
• Identify any material third parties required and explain their roles.
• Confirm whether you have previously integrated with an existing financial transaction switch rather than replacing it.
• Confirm whether your service can be delivered without changing Postbank’s current ACH clearing and settlement arrangement with PayInc.

• Provide a typical implementation plan, including dependencies, resource requirements and estimated timelines.
• Separate activities into discovery, design, build, certification/testing, pilot and go-live.

• Provide a detailed costing model covering:
