Concierge EOR Payrolling for One of the Largest Public Accounting Firms in the World

A global leader in advisory services sought a payrolling partner to improve onboarding for its contingent workforce. With a proprietary talent marketplace in place, they aimed to streamline operations and support supplier diversity while maintaining a top-tier candidate experience.

the challenge

A global leader in assurance, tax, transaction, and advisory services utilizes a large contingent workforce, including executive-level advisors, marketing and IT consultants, project managers, and customer service representatives. The company leverages a sophisticated internal direct sourcing recruitment approach using its proprietary talent marketplace technology to match contract workers with consulting roles.

While the recruitment strategy ensured access to a pool of high-quality candidates, it was important to the company’s recruitment team to ensure the selected candidates had a best-in-class onboarding and employment experience with external partners to maintain its reputation as an employer of choice in the market. To that end, the company sought a new payrolling partner that could offer a high-quality experience with streamlined operations while supporting their corporate initiative of treating supplier diversity as a social and business priority.
