Four Critical Risks in Merchant Onboarding
A strong onboarding process offers thorough and flexible risk controls to help protect your platform from a variety of threats. At a minimum, it should screen for these four primary types of merchant risk:
1. Money Laundering & Compliance Risk
Ensure the merchant is a legitimate business, not a front for illegal activity. Your process should:
- Comply with AML (anti-money laundering) laws and card network rules.
- Collect business registration, ownership, and licensing details.
- Run know-your-business (KYB) checks and verify against sanctions lists.
2. Fraud & Transaction Risk
Look out for red flags that signal fraud or financial abuse:
- Analyze fraud history and chargeback rates.
- Check for patterns like transaction laundering or unusual spikes in volume.
- Use transaction history to spot potential abuse of your platform.
3. Reputational Risk
The wrong merchant can hurt your brand. Protect your reputation by:
- Screening for adverse media mentions or ties to controversial activity.
- Avoiding merchants involved in unethical or illegal practices.
- Monitoring for industries or associations that could draw negative attention.
4. Financial (Credit) Risk
If you’re assuming financial liability, assess the merchant’s ability to meet obligations:
- Review creditworthiness, financial statements, and cash flow.
- Examine their ability to fulfill orders and avoid default or chargebacks.
- Gauge the stability and sustainability of their business model.
Key Steps for Effective Merchant Onboarding
Here’s a step-by-step onboarding checklist that reflects current industry best practices. Each step helps you identify potential risk while maintaining efficiency and a good merchant experience.
1. Pre-Screen Applications Early
Catch obvious red flags before investing time in full reviews:
- Validate basic info like website URL and phone number.
- Spot disqualifiers like unsupported business models or fake data.
- Save time by filtering out high-risk or non-serious applicants early.
2. Perform KYB Checks
Know-your-business checks verify that the company is real and properly registered:
- Collect and cross-verify business documentation (e.g., registration, EIN, licenses).
- Identify Ultimate Beneficial Owners (UBOs).
- Check the business name against global sanctions lists.
3. Vet the People Behind the Business (KYC)
Screen UBOs and executives to assess their credibility:
- Verify identity (e.g., ID, selfie match).
- Screen individuals for political exposure, sanctions, or criminal records.
- Search for negative media coverage or connections to fraud.
4. Assess Financial Stability
Evaluate whether the merchant can manage their financial obligations:
- Pull business and principal credit reports.
- Review processing history (volume, chargebacks).
- Analyze bank statements and P&Ls for viability and capital sufficiency.
5. Conduct a Holistic Risk Assessment
Go beyond the basics to understand the full picture:
- Identify high-risk industries or markets.
- Review website content and marketing materials for compliance.
- Use tools such as LegitScript’s Merchant Onboarding to scan for restricted products or misleading claims.
- Assign a risk tier or score based on all available information.
6. Make an Informed Onboarding Decision
Use a structured approach to approval:
- Use automation to flag low-risk for instant approval, and high-risk for auto-decline.
- Manually review edge cases and set conditional terms (e.g., reserves or caps).
- Communicate decisions promptly to deliver a positive experience.
7. Set Up Ongoing Monitoring
Onboarding doesn’t end with approval. Ongoing merchant monitoring is an essential part of maintaining the integrity of your merchant portfolio. After a merchant has been approved:
- Flag merchants for future compliance checks based on initial risks.
- Re-scan high-risk websites and conduct periodic reviews.
- Monitor for changes in behavior or risk indicators.
Best Practices to Strengthen Your Onboarding Process
Use Multiple Data Sources
Don’t rely on one document or database. Cross-verify data points to uncover inconsistencies and reduce fraud risk.
Automate Where It Makes Sense
Automation improves speed and accuracy:
- Automatically pull credit reports, run watchlist checks, and verify registrations.
- Free your team to focus on high-value risk analysis, not repetitive tasks.
Involve the Right Stakeholders
Effective onboarding requires cross-functional collaboration:
- Risk and Compliance teams ensure thorough checks.
- Sales and Product teams optimize the experience.
- Legal and Marketing help align with regulation and brand standards.
