The choice between billing models significantly impacts cash flow timing, revenue predictability, and profit margins. Firms typically use multiple billing structures across their client portfolio.

• Benchmarks vary by firm size, service type, and market positioning

• Directly impacts profitability, cash flow, or operational efficiency
