Merchant Onboarding Software Drives 60% Faster Activation for a US Acquirer

THE CLIENT 

A $40 Billion Payment Provider Running Merchant Onboarding Across Four Disconnected Gateways 

The client is a leading provider of integrated payment and frictionless commerce solutions, processing over $40 billion in annual payment volume across SMB and enterprise merchant segments. 

With multiple payment gateways and front-end acquirers supporting mission-critical transaction processing, the complexity of managing fragmented onboarding portals, inconsistent APIs, and diverse gateway configurations was slowing merchant acquisition and straining operations. 

To sustain growth and improve merchant experience, the client engaged Opus to design and build a unified omnichannel onboarding platform from the ground up. 

THE CONTEXT 

Four Gateways. Multiple Portals. A 35-Year-Old Platform. Every New Merchant Felt the Pain. 

Four structural challenges were limiting the speed and scalability of merchant onboarding: 

• Merchant onboarding timelines too slow to sustain acquisition growth: Multiple gateways and portals created inconsistent, time-consuming onboarding experiences that slowed merchant activation and frustrated the teams managing it, directly constraining revenue growth from new merchant relationships 

• 100% merchant satisfaction impossible to achieve across fragmented, inconsistent experiences: Inconsistent gateway behaviors, inconsistent APIs, and inconsistent onboarding flows meant merchant experience varied by platform, making it structurally impossible to deliver the consistent, reliable experience that 100% satisfaction required 

• 99.99% platform availability unachievable on a 35-year-old multi-gateway architecture: A 35-year-old platform supporting four-plus payment gateways with no unified approach for expansion or sustainability could not provide the high-availability foundation that mission-critical payment processing demanded 

• Sub-5ms response times blocked by fragmented API models and gateway complexity: Inconsistent API behaviors across gateways and the absence of standardized API management created latency and reliability gaps that prevented the platform from meeting the response time thresholds modern merchant transaction processing required 

WHAT OPUS ENGINEERED 

A Unified Omnichannel Merchant Onboarding Platform With Standardized APIs and Built-In Analytics 

Opus partnered directly with the client’s product management team to design and deliver a modern, centralized onboarding platform aligned with long-term business goals: 

• Unified platform development: A single-entry omnichannel platform consolidating multiple payment gateways into one consistent onboarding experience across all acquiring segments, replacing the fragmented multi-portal model 

• Seamless store-level migration: Existing merchants were migrated to the new platform through a unified API portal with minimal disruption and operational risk to live payment processing 

• Flexible platform enablement: Merchants gained the ability to select any store or gateway, allowing adoption of new platforms based on evolving business needs without requiring re-onboarding 

• API management and analytics via Apigee: Apigee API management, analytics, and monetization capabilities standardized APIs across all gateways, enabled performance insights, and optimized costs across the platform 

• Platform specifications delivered: 200-plus APIs, 500 transactions per second on 8 cores, 1 million transaction volume capacity, sub-5ms SLA response time 

WHAT CHANGED 

Merchants Activated Faster. Satisfaction Hit 100%. The Platform Never Goes Down. 

• Merchant onboarding timelines dropped by 60% as streamlined workflows and standardized APIs removed the friction that had made every activation a multi-step, multi-portal effort 

• Customer satisfaction for merchant onboarding reached 100%, reflecting the consistency and reliability that the unified platform delivered to every merchant segment 

• Platform availability reached 99.99%, delivering a measurable increase in high availability for mission-critical payment services across the full merchant base 

• Sub-5ms SLA response times and 500 transactions per second capacity gave the client a platform built not just for current volume but for the growth ahead 

• The standardized API framework and scalable portal positioned the client to expand gateway coverage and onboard new merchant segments without rebuilding the underlying infrastructure
