Custom Fintech Software Development

Modern fintech products require more than a dashboard and a few APIs. They need reliable transaction workflows, secure access controls, accurate ledgers, provider integrations, reconciliation, failure handling, auditability and a scalable backend.

Scriza develops custom fintech software around the client's use case, operating model and integration ecosystem. We can build a new platform from the ground up, extend an existing application, modernize legacy workflows or integrate third-party financial APIs into an existing product.

Our focus is software engineering: architecture, backend development, web and mobile interfaces, role-based dashboards, API orchestration, transaction records, reconciliation tools, notifications, reporting and operational controls.

Fintech Solutions We Develop

From payment platforms to white-label fintech products — we engineer software that handles real transactions, real APIs and real business logic.

Payment Platform Development

Custom transaction platforms with configurable payment workflows, status tracking, reporting, reconciliation and integration-ready architecture.

Fintech API Integration

Integration of authorized third-party banking, payment, verification and financial APIs into client applications using secure API and webhook flows.

Wallet & Ledger Systems

Transaction-grade wallet and ledger modules for credit, debit, fees, commissions, reversals, adjustments, remarks and balance reporting.

Merchant Management Software

Onboarding, KYC workflow, role permissions, package assignment, transaction controls, settlement views and merchant reporting.

Payout Software Development

Software workflows for initiating, tracking and reconciling payouts through client-authorized payout APIs and banking partners.

BBPS / Bill-Payment Integration

Custom software integration for bill-payment use cases where the client has the required access, approvals and authorized API partners.

Recharge Platform Development

Recharge and service-aggregation software with provider mapping, API routing, transaction status, callback handling and reports.

KYC & Verification Integration

Identity, bank-account and business verification workflows through permitted third-party verification APIs.

API Partner Platform

Developer dashboards with API credentials, IP management, token controls, API documentation, callback URLs, wallet, reports and logs.

White-Label Fintech Software

Configurable multi-tenant software with brand themes, domains, user hierarchy, packages and client-level controls.

Reconciliation & Settlement Tools

Automated and assisted reconciliation workflows to compare internal transactions with provider or banking records.

Fintech Mobile App Development

Android and iOS applications connected with the same secure fintech backend and role-based platform architecture.

Core Fintech Modules

Each module can be included or excluded depending on project scope. Our modular approach ensures you only build what your business needs.

Admin & Operations Dashboard

Business KPIs, transaction monitoring, service configuration, user controls and operational alerts.

Role & Permission Management

Custom roles, module-wise permissions and access restrictions for admin, staff, partner, distributor, merchant and API user roles.

User / Merchant Onboarding

Registration, profile, business details, document upload, KYC workflow and approval status.

Wallet & Ledger

Opening balance, credit/debit, transaction entries, charges, commission, refunds, reversals, adjustments and remarks.

Charges & Commission Engine

Fixed, percentage, slab or package-based commercial rules.

Provider / API Management

Provider master, service mapping, primary/backup API selection and configurable routing.

Transaction Management

Transaction ID, provider reference, timestamps, request/response state, success/pending/failed status and exception handling.

Callback & Webhook Logs

Raw callback capture, verification, processing status, retries and searchable logs.

Reconciliation Module

Mismatch identification, provider comparison, settlement tracking and downloadable reports.

Developer Zone

API token, IP whitelist, callback URL, docs, sample requests/responses and test credentials.

Notifications

Transactional email, SMS, WhatsApp and push integration based on client requirements.

Audit Logs

Login, configuration, wallet, role, token and operational activity records for traceability.

Multi-Provider API Routing & Failover

When a fintech platform depends on multiple providers, software reliability also depends on how provider failures, timeouts and status differences are handled. Scriza can develop configurable API-routing logic that supports primary and backup providers, service-wise mapping and transaction-level logs.

Ledger & Reporting

Routing logic supports priority, backup selection, timeout handling, response mapping, retry rules, manual switching and provider-wise success monitoring.

Wallet, Ledger, Charges & Commission Engine

Financial software needs a clear and auditable record of every balance movement. Scriza can build wallet and ledger modules where every credit, debit, fee, commission, reversal and administrative adjustment creates a traceable entry.

Commercial rules can be designed around the client's model — fixed charge, percentage charge, slab, package, service-wise fee, user-group pricing or partner commission. The software calculates applicable values, stores the calculation basis and shows the impact in transaction and ledger reports.

Opening balance management
Credit / debit tracking
Fee & commission calculation
Reversal & refund handling
Administrative adjustments
Audit-logged wallet changes
Package-based pricing rules
Partner commission structures

Security-First Fintech Engineering

Fintech software should be designed with security controls at the architecture level rather than added only at the end of development.

HTTPS/TLS for data in transit
Secure password storage and credential handling
Role-based access control (RBAC)
2FA / OTP for sensitive actions where required
IP whitelisting for API access
Signed or verified webhooks where provider capability allows
Rate limiting and abuse protection
Audit trails and administrative logs
Development / staging / production separation
Backup and disaster-recovery planning
Vulnerability testing / VAPT coordination
Secrets management — no keys in frontend code or public repositories
