The 3 Stages of Money Laundering: Placement, Layering, Integration

Certivus AML team11 minUpdated 2026-06-27

In brief: Money laundering usually moves criminal property through placement, layering, and integration, but professional firms often see only fragments of the pattern and need a documented way to assess and escalate risk.

Key points

  • Placement introduces criminal funds into the financial or professional-services system.
  • Layering moves value through transactions, entities, assets, or jurisdictions to disguise origin.
  • Integration makes the funds appear legitimate, often through property, business activity, loans, dividends, or professional advice.

What are the three stages of money laundering?

The three stages of money laundering are placement, layering, and integration. In real client work they rarely appear as a neat sequence. A UK accountancy firm or law firm may only see a new company, a source-of-funds explanation, a property transaction, an unusual loan, or a client who cannot explain why money has moved through several accounts.

The point of understanding the stages is not to accuse a client. It is to recognise when the facts no longer fit the client's profile, document the concern, and decide whether customer due diligence, enhanced due diligence, refusal, or internal escalation is needed.

Stage 1: placement

Placement is the entry point. Criminal property is introduced into a system where it can be moved, converted, invested, or explained.

For professional firms, placement can appear as:

  • A new client paying large retainers from an account that does not match their profile.
  • A cash-heavy business asking for accounts, tax, payroll, or bookkeeping support.
  • Funds introduced as a director loan with weak evidence of origin.
  • A buyer using third-party funds for a transaction without a clear relationship.
  • A client asking for urgent work before identity, ownership, or source-of-funds checks are complete.

The risk signal is not simply "cash". It is a mismatch between the client, the transaction, the source of funds, and the explanation provided.

Stage 2: layering

Layering is the attempt to make funds harder to trace. This can involve multiple accounts, companies, jurisdictions, assets, invoices, loans, crypto wallets, nominee arrangements, or rapid movement of value.

Examples that matter for accountants and law firms include:

PatternWhy it matters
Repeated transfers between connected companiesMay create distance between the funds and their origin.
Back-to-back loans with unclear commercial purposeCan disguise the source of wealth or beneficial ownership.
Overly complex ownership structuresMay hide the person who ultimately owns or controls the client.
Unusual invoice chainsMay be used to justify movement of funds without real economic activity.
Money moving through unrelated third partiesMakes the source and control of funds harder to evidence.

Layering often creates the audit problem: the firm has documents, but the story behind them does not make sense.

Stage 3: integration

Integration is where illicit funds appear legitimate. The funds may be used for property, business acquisition, dividends, shareholder loans, luxury assets, professional fees, or investment activity.

For UK professional-services firms, integration risk often appears when a client says the funds are already clean because they are sitting in a bank account. A bank account is not proof of legitimacy. The firm still needs to understand the client, beneficial owners, purpose of the work, source of funds, and source of wealth when risk requires it.

What should a regulated firm do when the pattern appears?

Use a documented workflow:

  1. Record the facts without speculation.
  2. Compare the activity with the client risk assessment.
  3. Ask for proportionate evidence if the explanation is incomplete.
  4. Consider whether enhanced due diligence is needed.
  5. Escalate internally to the MLRO or nominated officer where suspicion may exist.
  6. Keep a decision log explaining what was checked, what changed, and why the firm continued, paused, or exited the relationship.

Evidence to keep

Keep enough evidence for another competent reviewer to understand the decision:

  • Client profile and expected activity.
  • Identification and verification records.
  • Beneficial ownership and control checks.
  • Source-of-funds and source-of-wealth evidence where required.
  • Risk assessment notes and review history.
  • Internal escalation notes.
  • Rationale for continuing, declining, or exiting.

Common mistake

The biggest mistake is treating the three stages as theory. They are a practical lens for asking better questions: why this client, why this money, why this structure, why now, and why does the explanation fit the evidence?

This guide is general information, not legal advice. If a suspicion arises, follow your firm's internal reporting procedure and the relevant UK AML obligations.

Common questions

What are the three stages of money laundering?

The three stages are placement, layering, and integration. Placement introduces criminal funds into a financial or professional-services channel. Layering moves and converts the funds to obscure their origin. Integration returns them to the client as apparently legitimate wealth. In practice the stages overlap and a UK firm usually sees only one of them.

What are the 4 stages of money laundering?

The established model has three stages. Some training material describes four by counting the predicate offence, the crime that generated the funds, as a separate first stage before placement. UK supervisory guidance, including FATF and NCA material, uses the three-stage model, so a firm-wide risk assessment should be written against placement, layering, and integration.

How many stages of money laundering are there?

Three: placement, layering, and integration. This is the model used in FATF, NCA, and UK supervisory guidance, and the one HMRC and professional-body inspectors expect to see reflected in a firm's risk assessment and training records.

What is the money laundering cycle?

The money laundering cycle describes the same three stages as a loop rather than a line, because integrated funds are often used to finance further criminal activity, which starts the cycle again. For a professional firm the practical significance is that a client can present at any point in the cycle, not only at placement.

Which stage of money laundering is easiest to detect?

Placement, because it is the point at which criminal funds first meet a regulated business and leave a record. It is also the stage a UK accountancy or law firm is least likely to see, since firms are usually instructed later. The stage most firms encounter is integration, when funds reappear as property purchases, business income, or investment.

What are examples of layering in money laundering?

Layering examples include rapid transfers between accounts or jurisdictions, loans between connected companies with no commercial purpose, over- or under-invoicing, converting funds into high-value assets and reselling them, and inserting holding companies or trusts that obscure who ultimately controls the money.
