Custom Payment Processing Software Development for Merchant Platforms

Uptime is not a feature. It is the product. We build payment infrastructure that processes millions of transactions with sub-second response times and 99.99% availability.


Payment Processing Services we could build for you

01

Custom Payment Gateway Development

Overview

How platforms build payment infrastructure they own and control: direct processor connections, smart routing, tokenization, and PCI-DSS compliance without paying a third-party gateway markup on every transaction.

What's included

Direct Processor Connections. Connect to acquirers directly. Skip the gateway middleman and their per-transaction fee.

Smart Routing. Transactions route to the processor with the highest approval rate for that card type, region, and amount.

Tokenization Vault. Card data tokenized at entry. Your systems never touch raw card numbers. PCI scope minimized.

Failover Logic. Primary processor down? Transactions reroute automatically. Zero downtime for your merchants.

Estimated impact

Direct processor connections save $0.05 to $0.15 per transaction vs gateway providers. Smart routing increases approval rates by 3 to 8%. For a platform processing 1M transactions/month, that is $50K to $150K saved annually.

02

Merchant Dashboard and Analytics Platform

Overview

How payment companies give merchants visibility into their money: real-time transaction monitoring, settlement tracking, chargeback management, and revenue analytics that help merchants understand where every dollar goes.

What's included

Real-Time Transactions. Every payment, refund, and chargeback visible the moment it happens. No waiting for batch reports.

Settlement Tracker. Merchants see when funds land in their account. Payout schedules, holds, and reserves explained clearly.

Chargeback Management. Disputes identified, evidence collected, and responses submitted from one interface. Win rate tracking included.

Revenue Analytics. Sales by channel, product, time period, and geography. Payment method mix and average ticket analysis.

Estimated impact

Merchants with real-time visibility reduce reconciliation time by 80%. Chargeback management tools improve dispute win rates from 20% to 45%.

03

Multi-Currency and Cross-Border Processing

Overview

How platforms accept payments globally without a separate processor in every country: dynamic currency conversion, local payment methods, FX optimization, and settlement in 25+ currencies.

What's included

Dynamic Currency Conversion. Customers pay in their local currency. You settle in yours. FX rates locked at transaction time.

Local Payment Methods. iDEAL, SEPA, Alipay, PIX, UPI. Each market has preferred methods. One API covers all of them.

FX Optimization. Best exchange rate sourced across providers automatically. Transparent markup, no hidden spreads.

Multi-Currency Settlement. Settle in the currency that minimizes FX exposure. Hold balances in multiple currencies.

Estimated impact

Offering local payment methods increases conversion by 20 to 40% in international markets. FX optimization saves 0.5 to 1.5% on every cross-border transaction.

04

Subscription and Recurring Billing Engine

Overview

How SaaS and subscription companies manage recurring revenue: flexible billing cycles, usage-based pricing, dunning logic, proration, and revenue recognition that keeps your finance team sane.

What's included

Flexible Billing. Monthly, annual, usage-based, tiered, and hybrid models. Any pricing structure your business needs.

Smart Dunning. Failed payments retried at optimal times with updated card details from network tokenization. Recovery rate 15 to 30% higher.

Proration Engine. Mid-cycle upgrades, downgrades, and cancellations calculated automatically. Credits and charges adjusted to the day.

Revenue Recognition. ASC 606 compliant revenue schedules generated automatically. Finance team gets accurate reports without spreadsheets.

Estimated impact

Smart dunning alone recovers 5 to 15% of churned subscribers. Usage-based billing with proration reduces customer disputes by 60% on billing-related support tickets.

05

PCI-DSS Compliance and Security Infrastructure

Overview

How payment platforms achieve and maintain PCI compliance without a permanent audit team: tokenization architecture, encryption standards, access controls, penetration testing, and security monitoring that makes compliance continuous.

What's included

Tokenization Architecture. Sensitive data replaced with tokens at the edge. Your application layer never processes raw card data.

Encryption at Every Layer. TLS 1.3 in transit, AES-256 at rest. Key management automated and rotated on schedule.

Access Controls. Role-based permissions with MFA, IP allowlisting, and session management. Least privilege enforced everywhere.

Continuous Monitoring. Security events logged, analyzed, and alerted in real time. Quarterly ASV scans and annual penetration tests scheduled.

Estimated impact

Tokenization architecture reduces PCI scope by 90%, cutting annual compliance costs from $200K+ to under $30K. Continuous monitoring catches 95% of threats before exploitation.

06

Payment Orchestration and Optimization Hub

Overview

How enterprises manage multiple payment processors, methods, and channels from one platform: orchestration layer that routes, retries, and reports across all providers without vendor lock-in.

What's included

Multi-Provider Routing. Stripe, Adyen, Checkout.com, and direct connections managed from one API. Switch providers without changing code.

Cascading Retries. Declined transactions retried on alternative processors automatically. Conversion recovered without customer involvement.

Unified Reporting. All providers, all channels, one dashboard. Reconciliation across processors automated.

A/B Testing. Test processor performance by traffic split. Route to the best performer for each transaction profile.

Estimated impact

Payment orchestration recovers 2 to 5% of declined transactions through cascading. Unified reporting saves 15 to 20 hours/month in manual reconciliation.
