Sub-Merchant Onboarding Without Technical Complexity
Most ISVs spend 18 months building payment infrastructure that breaks the moment they scale beyond 100 merchants. What they don't realise is they're solving the wrong problem entirely.
The real challenge isn't processing payments—it's building a sub-merchant onboarding system that handles compliance, risk management, and regulatory requirements without drowning your engineering team in financial services complexity.
PayFacLite® provides automated sub-merchant onboarding that transforms ISVs into payment facilitators without the technical overhead. Our platform handles everything from initial merchant applications through ongoing compliance monitoring, letting you focus on building software instead of becoming a fintech company.

The Hidden Cost of DIY Sub-Merchant Onboarding
Building your own sub-merchant onboarding system doesn't just consume engineering resources—it creates compounding risks that grow with every merchant you add.
When you build internally, you're not just writing code. You're becoming responsible for FCA compliance, PCI DSS requirements, anti-money laundering checks, and ongoing risk monitoring. Each new regulation means months of development work. Each compliance failure means potential fines and merchant churn.
Consider what happens when the FCA updates their Strong Customer Authentication requirements, or when PCI DSS introduces new data protection standards. Your engineering team stops building features and starts rebuilding compliance infrastructure. Meanwhile, your competitors using purpose-built platforms continue shipping product updates.
The mathematics are brutal: most ISVs underestimate onboarding costs by 300%. They budget for the initial build but ignore ongoing compliance maintenance, regulatory updates, and risk management overhead. A typical in-house onboarding system costs 400,000 in the first year and 150,000 annually thereafter—before counting opportunity cost.
Every month you spend building payments infrastructure is a month your competitors gain market share by focusing on their core product. Every compliance issue that slips through your custom system risks merchant relationships and regulatory standing.
How PayFacLite® Automates Sub-Merchant Onboarding
Our platform eliminates these costs and risks through automated workflows that handle the entire sub-merchant lifecycle while maintaining regulatory compliance.
Intelligent Application Processing
When a potential sub-merchant submits their application, our system immediately validates business information against Companies House records, performs automated credit checks, and runs enhanced due diligence through multiple data sources. This happens within minutes, not days.
The system flags high-risk applications for manual review while automatically approving low-risk merchants that meet predefined criteria. You define the risk parameters—we handle the execution.
Automated Compliance Monitoring
Compliance doesn't end at onboarding. Our platform continuously monitors sub-merchants for regulatory changes, transaction pattern anomalies, and risk threshold breaches. When issues arise, the system automatically initiates appropriate responses—protecting your payment facilitator status.
Streamlined Documentation and Verification
Document collection becomes automatic through our intelligent request system. Sub-merchants receive customised document requests based on their business type and risk profile. Our OCR technology extracts data from uploaded documents, automatically populating merchant profiles and flagging inconsistencies.
This eliminates the typical back-and-forth documentation process, reducing onboarding time from weeks to 48 hours while improving data accuracy.
Risk-Based Decision Engines
Our machine learning models evaluate sub-merchant applications using over 200 data points, from standard business metrics to behavioural indicators. The system learns from your approval patterns, becoming more accurate at identifying merchants that align with your business model.
Stop Building Financial Infrastructure. Start Scaling Your Business.
While your competitors wrestle with compliance requirements and regulatory updates, you could be onboarding merchants in 48 hours and focusing entirely on product development.
