About Williams Stanley & Co
Williams, Stanley & Co is a leading accountancy firm catering to a diverse range of clients within the hospitality industry, from high street chains to family-run cafes. Our company began with a mission to provide accurate and actionable financial insights to businesses, drawing from our founders’ own experiences in managing multiple rapidly growing ventures.
Driven by a commitment to customer-first accounting, we’ve assembled a team of experienced and trusted accountants who share our vision for excellence. With a strong emphasis on collaboration and expertise, our team operates seamlessly across different locations, including the UK, Philippines and Dubai.
As our client base continues to grow, we are expanding our Operations function and hiring a Client Onboarding Supervisor to ensure every new client experiences a smooth, structured, and professional transition into the firm.
Role Overview
The Client Onboarding Supervisor will own the end-to-end onboarding journey for new accounting and advisory clients, from the point of sale through to full handover into ongoing service delivery.
This role is critical to the success of our outsourced model. You will manage client transitions from previous accountants or inhouse finance teams, ensure all internal teams are fully prepared, and act as the central point of coordination across Sales, Account Managers, Bookkeeping, Payroll, Compliance, and Client Services.
Your goal is to deliver a consistent, compliant, and confidence-building onboarding experience — ensuring clients feel supported from day one and internal teams are set up for success.
