Consulting firms are in the business of solving complex problems for clients, not processing their own paperwork. Yet the AP function is critical—subcontractor invoices must be paid on time to retain talent, client-reimbursable expenses must be tracked precisely to recover costs, and overhead vendor bills must be processed accurately to maintain clean financials for the firm's own reporting. A virtual assistant for invoice processing in consulting firms handles this entire workload so your principals and project managers can stay focused on delivery.
Industry-Specific Invoice Processing Challenges
Management, IT, or strategy consulting firms frequently engage subject-matter-expert subcontractors who bill on a project or time-and-materials basis. Tracking these invoices against project budgets and ensuring they are approved by the responsible project manager before payment is a multi-step workflow that is easy to break down. Client-reimbursable expenses—travel, accommodation, software licenses purchased for an engagement—must be logged with receipts and included in client billing, or they simply become write-offs. Firms with multiple practice areas or offices need consistent GL coding to produce meaningful internal financial reports.
