Sanctions Screening Guide for Cross-Border B2B Marketplaces and SaaS Platforms
A practical sanctions screening guide for B2B marketplaces and SaaS platforms that move money or goods across borders, covering onboarding, ongoing monitoring and audit-ready evidence for banks, PSPs and enterprise customers.
•8 min read
Cross-border B2B marketplaces and SaaS platforms sit in an awkward middle ground:
You move money or goods internationally
You touch high-risk sectors (manufacturing, logistics, professional services)
But you aren’t a bank – and you don’t have a 30-person compliance team
This guide gives product, ops and compliance leads a practical playbook for setting up sanctions screening that:
Protects payment and payout flows
Supports marketplace trust & safety
Generates documented audit trails for partners and regulators
Stays realistic for lean teams (1–3 people, not 50)
1. Why B2B marketplaces and SaaS platforms can’t ignore sanctions
If your platform lets businesses:
Pay each other for goods or services
Store balances (wallets, credits, virtual IBANs)
Arrange cross-border shipments or projects
…then you’re exposed to sanctions risk, even if you don’t hold a banking licence.
Typical risk drivers:
Cross-border flows: buyers in the EU paying sellers in higher-risk regions
Complex supply chains: sub-suppliers or logistics partners hidden behind a primary vendor
Multi-tenant structure: one platform, many merchants / tenants, each with different risk levels
Payment partners’ expectations: acquirers, PSPs and banks increasingly require your own
sanctions policy, not just theirs
What’s at stake:
De-risking by your bank or PSP (account or MID closed with short notice)
Scheme or marketplace suspension (cards, alternative payment methods, wallets)
Contract loss with large enterprise customers who expect sanctions due diligence
Reputational damage if a sanctioned seller, buyer or transaction is exposed in the press
2. Map your sanctions exposure by business model
Before buying tools or writing policy, map where sanctions risk actually lives in your product.
Run a full name check for entity + key individuals against your sanctions lists
Capture results in an audit log entry linked to the account / tenant
If there’s a potential hit:
Flag the account with a “Compliance review” status
Assign a reviewer and capture their decision (clear / escalate / reject)
Store evidence (screenshots or PDFs of the screening results)
MatchAudit can automate:
Screening via UI or API during onboarding
Writing audit-ready logs and generating PDF reports that can be shared with partners
Re-screening active customers on a schedule (e.g. weekly)
4.2 Ongoing monitoring: active tenants and high-value accounts
Instead of re-screening everyone every day, focus on:
Active tenants (recent invoices, shipments, projects, logins)
High-value accounts by revenue or volume
Higher-risk corridors (e.g. exports to specific regions)
Practical pattern:
Maintain an “active counterparties” list (ACM – Active Counterparties per Month)
Push that list to your sanctions engine weekly for re-screening
Only open cases when:
There’s a new hit
A match score increases substantially
A customer moves into a higher-risk country or sector
This keeps alerts manageable for lean teams while staying defensible in reviews.
4.3 Payments, payouts and wallets
For platforms that move money:
Screen payees / sellers before first payout
Re-screen when bank accounts or payout details change
Add rules like:
Block payouts if a sanctions hit is pending
Require a manual review if large payouts are going to higher-risk countries
Where possible, align with your PSP / acquiring bank:
Share your sanctions policy and technical flow
Show examples of MatchAudit PDF reports and audit logs
Clarify who screens what (you vs. them) to avoid gaps or duplication
5. Reducing false positives without missing true risk
B2B platforms often struggle with:
Common company names (e.g. “Global Trading”, “International Consulting”)
Transliteration and spelling variations
Very noisy results from generic tools
Key levers to improve precision:
5.1 Use more than just the name string
Improve matching by considering:
Country of registration / operation
Date or year of birth (for individuals)
Industry or sector (construction vs. software vs. logistics)
Hit evaluation workflow:
Check if country overlaps with the sanctions entry
Check if date/year of birth is compatible
Look at program / regime (Russia, terrorism, DPRK, etc.)
Decide: clear as false positive, escalate, or block
5.2 Tune matching and use “explainable” scores
Look for screening that gives:
A numeric confidence score
A clear explanation: which fields matched and why
This is exactly what MatchAudit optimises for: explainable scores with human-readable reasons that you can paste into a case file or partner questionnaire.
6. Evidence, auditability and partner expectations
For B2B marketplaces and SaaS businesses, the “customer” is often:
An enterprise buyer (procurement, risk, or compliance team)
A PSP or bank underwriting your flows
A card scheme or payment network
All of them care about evidence more than marketing slides.
You should be able to:
Produce an export of screening activity (e.g. by date range, by counterparty)
Show individual case histories: what was screened, what matched, who approved what
Share PDF reports that stand up in a governance committee or regulatory inspection
MatchAudit helps by:
Logging each search / API call with a timestamp, user/API key and parameters
Storing match details and decisions per event
Generating structured PDF reports that you can attach to RFP responses or partner reviews
7. Minimum viable sanctions program for B2B marketplaces & SaaS
If you’re starting from zero, a realistic MVP looks like this:
Policy
4–6 pages covering:
Scope (who you screen, when, and against which lists)
Governance (who approves policy and high-risk decisions)
Escalation paths (who you talk to when there’s a real hit)
Record-keeping and retention
Controls
Onboarding screening for new customers, vendors or tenants
Weekly re-screening of active counterparties
Pre-payout checks for higher-risk markets
Manual review workflow for hits
Evidence
Centralised audit log of all screenings
Standard decision templates (“Why this match?” and “Why this is a false positive”)
Exportable reports for banks, PSPs and large customers
8. How MatchAudit supports B2B marketplaces and SaaS platforms
MatchAudit is built specifically for non-bank institutions that need structured screening evidence:
One dashboard + API for sanctions checks across UN, EU, OFAC, UK and more
Name-matching tuned for business names and people with clear, human-readable explanations
PDFs and exports you can attach to RFPs, bank reviews and scheme audits
Re-screening support (CSV, async jobs and scheduled runs) so you can keep active
counterparties up to date
Whether you run a B2B marketplace, billing platform or vertical SaaS, you can start with a lean, realistic sanctions program and grow into more automation as volumes and expectations increase.
