Acquirer Solution Available / Current Platform
Integrate Once. Connect to Multiple Acquirers.
MerchantPaisa Acquirer Solution is an enterprise payment acquiring, processing, routing and financial-switching platform designed to connect banks, fintechs, PSPs and payment platforms with multiple acquiring providers and payment networks through a unified processing architecture.
Financial institutions and payment platforms can integrate once with MerchantPaisa instead of rebuilding provider-specific payment-processing logic for every acquirer, processor or rail.
The platform centralizes validation, idempotency, risk, limits, provider selection, credential selection, transaction execution, timeout recovery, scheme clearing, settlement, reconciliation and financial operations.
Challenge
- Different APIs, protocols and transaction capabilities
- Hardcoded routing and inconsistent financial states
- Ambiguous timeouts that can create duplicate charges
- Fragmented clearing, settlement and reconciliation
MerchantPaisa response
- One canonical payment API and lifecycle
- Configurable routing, Risk and Limits controls
- Safe recovery, inquiry and reversal workflows
- Connected ledger, clearing, settlement and operations

Management Portal Roadmap
MerchantPaisa Management Portal
Centralized Operational and Configuration Control for the MerchantPaisa Payment Platform
The MerchantPaisa Management Portal gives authorized operational, technical and administrative teams centralized visibility and control across the acquiring and payment-processing platform.
It is designed for authorized internal and operator users, not public merchant checkout users.

MerchantPaisa API Platform
MerchantPaisa API Platform is the next stage of the MerchantPaisa enterprise integration layer, expanding the platform with additional APIs, management capabilities, provider connectivity and reusable integration services.
Who uses it
Built for the Payment Ecosystem
MerchantPaisa is positioned for organizations that need controlled payment infrastructure without embedding provider behavior throughout their upstream platform.

Smart routing
Route Every Transaction Intelligently
Routing policies are centrally configurable and evaluate eligibility before optimization. This avoids unsafe provider shopping and keeps provider capability, health and credential compatibility visible.

Credential processing
Secure Credential Processing by Design
PaymentInstrumentId abstracts the credential boundary while card-vault, provider-token, network-token and stored-credential behavior remain controlled by configuration and provider compatibility.
CVV is never persisted after authorization.

Financial lifecycle
From Payment Approval to Financial Completion

First Presentment
Eligible captured or financial transactions can be transformed into scheme-clearing records and prepared for submission according to the selected clearing profile.
Second Presentment
MerchantPaisa connects its Disputes & Chargebacks workflow with the Clearing Engine so an approved representment decision can produce a controlled second-presentment financial submission.
Authorization-to-Clearing Matching
Clearing records can be correlated with original payment activity using available transaction references and configured matching profiles.

Controlled scheme file processing
Resubmission Without Losing Financial Control
MerchantPaisa retains the original file and record history when clearing submissions are rejected or require correction. Resubmissions follow controlled lifecycle and duplicate-prevention rules rather than overwriting previous financial history.
- Duplicate file and record protection
- Sequence control and file audit history
- Secure file transport abstraction
- Acknowledgement and rejection handling
- Controlled correction and resubmission

Fees, settlement and reconciliation
Configurable Scheme Financial Processing
Configurable Interchange & Scheme Fee Processing
MerchantPaisa includes a versioned, effective-dated calculation framework for interchange and scheme/network fees. Actual production rates and rules must be configured from authorized Visa, Mastercard, sponsor or processor specifications.
Scheme Settlement Processing
Accepted clearing input, settlement positions, gross/net processing, refunds, reversals, fees, multiple currencies, FX readiness, business dates, settlement cycles, confirmation and mismatch handling.
Settlement Reconciliation
MerchantPaisa compares clearing, scheme/sponsor data and settlement results to detect amount, currency, count, fee, FX, missing-record, duplicate and three-way mismatches.
