Unbilled and Underbilled Consulting Hours in Proposals and SOWs

3 verified sources

Definition

In operations consulting, a significant share of delivered work is never billed because hours spent in pre‑sales discovery, solution design, and SOW refinement are not captured or not included in the commercial scope. Studies on professional and consulting services show that around 15% of chargeable consulting work is never billed, directly eroding project and firm profitability.

Key Findings

  • Financial Impact: ≈15% of consulting revenue at risk annually (industry studies on professional/consulting services)
  • Frequency: Daily
  • Root Cause: Manual and fragmented time tracking during proposal/SOW development, lack of clear policy on what pre‑sales work is billable, and poor handoff between sales/partners and finance so that additional scope defined in SOWs never reaches billing systems.[3][7][2]
