Data Warehousing for Professional Services: Time, Billing, Matter, and Client Data Unified

A firm builds a data warehouse and the compensation committee doesn't use it. The reasons are familiar: the warehouse's partner-level attribution differs from the billing system's origination/working credit because the methodology wasn't encoded correctly. Utilization numbers differ from the practice group reports finance produces manually. Client lifetime value calculations use inconsistent methodology across analyses. Ethical walls aren't respected in the warehouse's join patterns — data from Client A influences analyses involving Client B because walls weren't enforced architecturally. The compensation committee goes back to using the billing system's native reports for origination discussions, and the finance team maintains spreadsheets for practice group reviews. The warehouse investment doesn't pay back at the decision moments that matter.

Professional services warehousing done right encodes the compensation-relevant methodology and ethical wall discipline from day one. Partner attribution with the firm's origination/working/supervising credit methodology matching the billing system. Utilization with the firm's target-hours policy matching practice group reports. Client lifetime value with documented methodology the compensation committee has validated. Ethical walls enforced architecturally with practice group isolation where applicable. Matter and engagement profitability with overhead allocation methodology. Client master data with deterministic matching. Reconciliation to PSA and billing after every load. Done with this discipline, the warehouse becomes the instrument the compensation committee and practice group leaders use. Done generically, it stays a parallel reality.
