Client onboarding for an accountancy or advisory firm includes the mandatory know-your-customer (KYC) and anti-money laundering (AML) checks required under the Money Laundering Regulations before a new client engagement can begin, alongside the practical setup of client records, engagement letters and service scope. These checks are a regulatory requirement enforced by professional body supervisors, not an optional internal process, and firms must be able to evidence them on request. EdgeAdvisory™, Advantage's AI accelerator for accountancy and advisory firms built on Business Central, structures client onboarding so AML evidence is captured and auditable from the first record created.
How structured onboarding supports AML compliance
Capturing identity verification, beneficial ownership information, risk assessment and supporting documentation as a structured part of the client setup process within Business Central, rather than as separate paperwork stored elsewhere, gives a firm a single auditable record per client from day one. EdgeAdvisory can flag clients due for periodic risk review, ensure new engagements cannot proceed without the required AML checks being marked complete, and keep a clear, time-stamped history of when checks were carried out and by whom, which is exactly the evidence a professional body supervisor or HMRC review will ask for.
Client onboarding in practice
- A new client engagement is held in EdgeAdvisory until AML and identity verification checks are marked complete, preventing work from starting before compliance requirements are met.
- A firm undergoing a professional body AML inspection produces evidence of completed checks for every client directly from Business Central, rather than searching through separate paper files.
- A practice uses automated review reminders to identify clients due for periodic AML risk reassessment, rather than relying on individual partners to track this manually.
- A firm onboarding a higher-risk client applies enhanced due diligence steps consistently, with the additional checks and documentation captured in the same structured record as standard onboarding.
How Advantage supports AML-compliant onboarding with EdgeAdvisory
EdgeAdvisory structures client onboarding within Business Central so identity verification, risk assessment and AML documentation are captured consistently and remain auditable for as long as regulatory requirements demand. We help practices reduce the compliance risk that comes from AML evidence being scattered across separate paper files or disconnected systems.
Frequently Asked Questions
Common questions about KYC and AML client onboarding for UK accountancy firms.
What KYC checks are accountancy firms legally required to carry out?
UK accountancy firms are supervised under the Money Laundering Regulations and must carry out customer due diligence on every new client, including verifying identity for individuals and beneficial ownership for companies, understanding the nature and purpose of the client relationship, and assessing money laundering risk. Higher-risk clients require enhanced due diligence, involving more detailed checks and ongoing monitoring rather than a one-off verification at the start of the relationship.
Why is documented evidence of AML checks so important for a practice?
Professional body supervisors, such as ICAEW or ACCA, and HMRC where relevant, can request evidence that AML checks were carried out and properly documented for any client at any time. A firm unable to produce this evidence, even where the underlying checks were genuinely performed, risks regulatory action and reputational damage, making structured, auditable record-keeping as important as the checks themselves.
How does ongoing monitoring differ from initial onboarding checks?
Initial onboarding checks establish a client's identity and risk profile at the start of the relationship, but money laundering regulations also require ongoing monitoring throughout the relationship, meaning firms must periodically review client risk and update due diligence information, particularly when a client's circumstances change significantly. A system that flags clients due for periodic review, rather than relying on staff to remember, reduces the risk of stale or incomplete AML records.
