THE PROCESSING FOUNDATION

Keep complexity
behind the interface.

Normalize payment intent, response meaning and recovery behavior—without erasing the rules of each provider.

Payment lifecycle

Sale, authorization, capture, void, refund, reversal and inquiry within configured provider capabilities.

Policy-based routing

Evaluate merchant, scheme, currency, channel, capability, health and priorities before provider selection.

Risk, limits & eligibility

Apply configured transaction rules and limits before financial transmission.

Idempotency & duplicates

Protect repeated requests and preserve financial intent through the supported transaction lifecycle.

Provider abstraction

Keep protocol mappings, credentials, response codes and provider behavior inside dedicated adapters.

Operational visibility

Make outcomes, attempts, provider behavior and recovery exceptions visible to authorized operators.

BUILT FOR THE DIFFICULT CASES

Uncertain response.
Controlled next step.

A timeout is not automatically a decline. When a payment may have reached a provider, recovery must preserve financial truth.

No blind rerouting after
ambiguous financial transmission.

Inspect the transmission state. Use supported inquiry or reversal. Resolve the original financial intent before considering a new attempt.

IN_DOUBT

Investigate before retrying.

The provider response is uncertain. Preserve the original intent and resolve it through the configured recovery workflow.

AFTER AUTHORIZATION

Track clearing
and settlement.

Connect presentment, acknowledgement, settlement, reconciliation and payment-event accounting in a controlled financial lifecycle.

01

Clearing & presentment

Prepare eligible records, match authorizations, generate files and handle acknowledgements, rejects and controlled resubmission.

Original history retained
02

Interchange & fees

Configure versioned, effective-dated calculations from authorized provider, sponsor or scheme specifications.

Rates from authorized specifications
03

Settlement positions

Track gross/net positions, fees, settlement cycles, currencies, confirmations and financial exceptions.

Explicit financial state
04

Reconciliation & accounting

Compare clearing, sponsor/provider data and settlement results; connect outcomes to switch accounting and exception review.

Differences stay visible

Visa / Mastercard clearing readiness

Internal UAT and pre-certification are not external Visa or Mastercard approval. Official specification mapping and external certification are still required before production scheme use.

CONNECTIVITY WITH CLEAR CONDITIONS

Different providers.
A consistent foundation.

Integrate the rails and acceptance channels your operating model requires, using validated profiles and the right external approvals.

Card-present EMV/contactless, e-commerce/3DS, stored credentials, tokenization and wallet-payment acceptance depend on the provider, market and agreed implementation.

IMPORTANT DISTINCTIONS

What requires
separate approval?

Is MerchantPaisa officially Visa or Mastercard certified?

No completed external scheme certification is claimed. Internal UAT and pre-certification are engineering milestones, not network approvals.

Does 3-D Secure mean a payment is authorized?

No. Cardholder authentication and financial authorization are separate stages. A 3DS result does not itself authorize funds or guarantee acceptance.

Are all payment wallets and local schemes available?

No universal availability is claimed. Wallet acceptance, local schemes, account updater and network tokens require provider compatibility, enrollment, agreed scope and any necessary external approval.

Is the switch ledger a complete accounting system?

The ledger scope is payment-event and switch accounting. It is not presented as a replacement for corporate accounting, an ERP or jurisdiction-specific financial reporting.
