Data Integration for Professional Services: PSA, Billing, Payroll, and GL Connected

Professional services integration connects systems that handle time, money, and engagement lifecycle uniquely. Time entries flow from timekeepers through PSA into billing with the matter/engagement structure that determines eligibility, rates, and approval workflow. Expenses flow from expense systems (Concur, Chrome River, SAP Concur) through matter validation to billing. Prebills circulate between timekeepers and billing teams for review, write-down, and approval before billing. Invoices flow to clients in the specific formats clients require (electronic billing through LEDES formats for law firms, client-specific templates for consulting). Collections flow back with cash application to matters. Payroll integration (ADP, UKG, Workday) handles timekeeper compensation with utilization and origination linkage. GL integration with the dimensional structure that supports partner-level profitability. Each integration has specific timing, compliance, and audit requirements.

Professional services integration done right follows time-to-cash patterns. Time entry integration from mobile time capture (Intapp Time, Bellefield, native PSA mobile) through PSA to billing with validation at each hop. Expense integration with matter-level cost attribution. Prebill workflow with timekeeper review, write-down tracking, and the audit trail compensation reviews scrutinize. LEDES e-billing for law firms with client-specific variations. Client-specific invoice templates with the customization agencies and consultancies require. Collections with matter-level cash application. Payroll integration with origination/working credit. GL with partner-profitability dimensional structure. Done with this discipline, the time-to-cash cycle runs predictably. Done generically, manual reconciliation becomes a significant portion of finance team capacity.
