Money laundering controls are not just a bank problem anymore. Fintechs, marketplaces, real estate firms, and service providers can end up in the flow of dirty funds without noticing.
A practical AML approach keeps regulators satisfied and protects your brand when something weird hits your payment rails.

Start With A Clear Risk Picture
Compliance work goes more smoothly when the business knows where the real exposure sits. Look at who your customers are, what products you offer, how funds move, and which countries touch the transaction path.
A simple risk register can track high-risk customer types, high-risk geographies, and the channels criminals like.
Write down the reasoning behind each risk rating. That document becomes the anchor for everything else: which checks you run at onboarding, how often you rescreen, and where you set alert thresholds.
When the business launches a new feature or partners with a new platform, update the risk picture before the first transaction goes live.
Make Independent Testing Part Of The Calendar
A written program looks good on paper, but weak spots show up in day-to-day work. Regular reviews, including AML audit services, can catch gaps before an examiner does. Treat testing like maintenance, not a one-off fire drill.
Plan testing around the riskiest flows first. A high-volume payments feature needs deeper sampling than a low-use legacy product, and a new onboarding path deserves a fast review after launch. Track findings in a simple log with an owner, a fix date, and evidence that the fix shipped.
Independence matters. A second set of eyes should validate controls, not just confirm that a checklist got completed. That can mean an internal audit team, a separate compliance reviewer, or an external specialist who can challenge assumptions and test alerts with real data.
Cover The Core AML Program Building Blocks
Most AML laws point back to a few building blocks: written policies, a named owner, training, and independent review.
A FinCEN fact sheet describing AML program expectations calls out 4 core elements, including a compliance officer, ongoing employee training, and an independent audit function. That framework is a clean starting point for many teams, even outside the U.S.
Policies should read like operating instructions, not a legal essay. Spell out what gets checked, when it gets checked, and who signs off on exceptions. Keep a change log, so updates tie back to a trigger, like a new product, a new partner, or a new regulatory note.
Assign ownership in plain terms. One person should be accountable for the program, and deputies should cover key tasks like case management, reporting, and vendor oversight. Without clear owners, controls drift, and alerts pile up.
Run Strong Customer Due Diligence And Monitoring
Customer due diligence starts before the account opens, and then keeps going through the life of the relationship.
Know what “normal” looks like for each customer segment, then watch for activity that breaks the pattern. Monitoring works best when it blends rules, data signals, and human judgment.
Set up controls that match the risks you actually see:
- Verify identity with reliable documents or trusted data sources
- Screen names against sanctions and watchlists at onboarding and on a schedule
- Collect beneficial ownership details when a customer is a company
- Use transaction rules that flag structuring, rapid in-and-out movement, or unusual counterparties
- Triage alerts with clear severity levels and documented decisions
Alert handling needs a consistent rhythm. Document why a case was cleared, what extra data was reviewed, and when a report was filed. Keep the evidence trail tight, since an auditor or regulator will ask how your team reached each decision.
Keep It Lean For Small Teams
Small teams feel the pressure first: fewer people, fewer tools, and less time to tune systems. A FinIntegrity note on AML compliance for small businesses points out common challenges like limited resources, which can make it harder to build and maintain a full program.
Lean operations can still run solid controls with smart prioritization. Pick a small set of controls that cover the biggest risks, then execute them consistently. Templates help: onboarding checklists, alert playbooks, and a single case narrative format cut down rework.
When budgets are tight, focus on clean data, clear procedures, and training that teaches staff how to spot red flags in your product.
Use vendors carefully. Vendor screening can cover sanctions checks, identity verification, and transaction monitoring, and someone internal still needs to own the decisions. Review vendor performance using metrics like false positives, time-to-close, and the quality of audit logs.
Prepare For Rule Changes And Cross-Border Gaps
Cross-border business brings conflicting definitions, different thresholds, and different expectations for recordkeeping.
A Deloitte Legal perspective on the EU AML package describes a push to strengthen rules and harmonise requirements across member states, aiming to close legal gaps. When rules shift in one region, policies and controls can lag in another.
Build a light change-management process. Track regulatory updates, tie them to policy edits, and keep version control on procedures so staff follow the current steps. Map key controls to the rule they support, so audits focus on evidence.
AML compliance works best when it feels like part of operations, not a separate project. Start with a clear risk view, build core controls, and keep monitoring and testing on a steady cadence. Small improvements add up fast when every decision leaves a clean record.
