The Challenge
The firm’s core invoicing bottleneck was rooted in communication breakdowns between its sales consultants and finance staff.
Consultants, focused on delivering placements, often delayed or inaccurately supplied the information needed to raise invoices. This delay not only frustrated the finance team but also had a tangible business impact: invoices weren’t sent out on time, and debtor days were creeping up significantly, reaching 66 days in some instances.
The invoicing process was further complicated by regional differences in requirements across the US, UK, and EU entities, and inconsistent use of the CRM (Bullhorn) as the system of record.
