Common Pitfalls & Mitigation:
- Incomplete Documentation: Implement mandatory fields in digital forms and automated reminders for missing documents.
- Delayed Client Communication: Establish clear communication SLAs (e.g., respond within 1 business day) and automated follow-up sequences.
- Incorrect Service Setup: Mandate a final review of PMS service setup by EP/CRM against the signed engagement letter.
- Client Overwhelm: Break down data requests into manageable stages; provide clear, concise instructions and offer live support sessions.
- Lack of Internal Handoff Clarity: Utilize standardized templates for client briefs and mandatory internal meetings with clear agendas and action items.
Audit Checklist (Quarterly Review):
-

7. Troubleshooting FAQ
Q1: Client is unresponsive or significantly delayed in providing requested documents/information. A1:
- Escalate Communication: After 3 business days of no response, send a polite follow-up email outlining the impact of the delay on service commencement.
- Offer Assistance: Proactively offer a brief call to clarify requirements or assist with data collection.
- Involve CRM/EP: If delays persist beyond 7 business days, the Onboarding Specialist informs the CRM/EP to directly engage the client to understand obstacles and re-emphasize the importance of timely submission.
- Formal Pause: If no progress after 10 business days, formally communicate a pause in onboarding until required information is received, reiterating that service commencement timelines are impacted.
Q2: During KYC/AML checks, a discrepancy or red flag is identified (e.g., suspicious identity document, sanction list match). A2:
- Immediate Pause: Immediately halt the onboarding process. Do not proceed with any further steps.
- Inform Compliance Officer: Notify the Compliance Officer (CO) with all relevant details and evidence.
- CO Investigation: The CO will initiate an internal investigation, which may include requesting additional verification from the client through secure channels, consulting legal counsel, or reporting to relevant authorities if required by law.
- Decision: A decision will be made by the CO (potentially in consultation with EP) regarding whether to proceed with onboarding, request more information, or decline the client based on risk assessment and regulatory requirements. All actions and decisions must be meticulously documented.
Q3: Client experiences issues accessing the secure portal or integrated accounting software (e.g., login errors, permission issues). A3:
- First-Line Support (OS): Onboarding Specialist verifies user credentials, checks for common typos, and confirms account activation status.
- IT Administrator Escalation: If basic troubleshooting fails, escalate to the IT Administrator (ITA). Provide detailed error messages, client's operating system/browser, and steps taken.
- Remote Assistance: ITA may offer remote screen-sharing sessions to diagnose and resolve technical issues directly with the client.
- Alternative Access: If a persistent technical blocker exists, provide temporary alternative secure methods for data submission while the primary access issue is resolved, ensuring security protocols are maintained. Update client with resolution timeline.
