Professional Services Business Information Model

Everything the Firm Sells Is Recorded in Six-Minute Increments

Professional Services Business Information Model is a structured inventory of the business data entities an advisory firm runs on — client, engagement, resource, role, time entry, rate, work in progress, invoice — organized into foundational, transactional and informational layers, in an editable Word document with a guide to business data modeling.

A professional services firm's entire economic record is assembled from time entries. Every margin number, utilization figure, realization rate and client profitability report is a rollup of them, which makes the entities around a time entry — who recorded it, against what, at what rate, in what currency, chargeable or not — the most consequential definitions in the firm.

They are also usually the least examined. A person has a grade, a cost rate, a bill rate that varies by client and engagement, and possibly a different role on each project. Firms that model a single rate per person discover the limitation the first time they price work differently for a major client.

This model states those entities and their relationships. It is a business information model rather than a database design — it names what the firm means, which is the layer where realization and utilization arguments actually originate.

The Distinctions This Is Meant to Make

Three definitional problems that quietly distort firm reporting.

Client, account, or engaging entity? The relationship, the billing entity and the legal party to the contract can differ, particularly for group clients. Client profitability is only meaningful once the firm says which it means.

Engagement, project, or matter? One contract may carry several workstreams billed differently, or several contracts may serve one program. Modeling only one level makes the other invisible.

Which rate applies? Standard rate, client rate, engagement rate, cost rate and realized rate are five different numbers attached to the same hour. Realization is the ratio between two of them, which is why the definitions have to be explicit.

Why This Matters Now

Fee model change and firm consolidation both stress the same definitions.

Non-Hourly Fees Break Hourly Assumptions

Fixed-fee, retainer and outcome-based work still consumes hours, but the hour is no longer the revenue unit. The model has to hold both without one distorting the other.

Mergers Mean Reconciling Two Rate Structures

Combining firms means combining grade ladders, rate cards and engagement structures. Where neither firm wrote them down, the reconciliation happens person by person.

Practice Management Platforms Impose a Model

Adopting a new system means accepting its entities unless the firm defined its own first — and the entities determine what can be reported for years afterward.

What Is Included

Who This Is Built For

This model pairs with the Professional Services Capability Model, which states what the firm does; the information model states what it does it to. Neither substitutes for the other.

How to Put It to Work

• State which of client, account and engaging entity each profitability report means.
• Model rate as its own entity so a person can carry several without contradiction.
• Allow an engagement to contain several workstreams with different fee arrangements.
• Use it as the firm-owned target when evaluating a practice management platform.

Where Firms Typically Start

What You Are Actually Buying Is Time

Building this internally consumes partner and finance hours — the most expensive in the firm, and the ones with the strongest competing claim from client work.

• The first draft is the expensive part. Reviewing a proposed set of entities is a different task from inventing one, and a much shorter one.
• Disagreement becomes visible immediately. A written definition of realization surfaces the difference between two practices' numbers in the first session.
• It outlives the project that prompted it. The same model serves a system selection, a merger integration, and a profitability rebuild.

Those first two columns describe what comparable efforts tend to involve, not a quoted benchmark — your figures depend on scope and who does the work.

Built From Real Engagements

We are software entrepreneurs and business consultants who have delivered business architecture and transformation work across financial services firms. This model is the distilled, reusable output of that work rather than a theoretical exercise — which is also why it carries the limits described below.

An Honest Note on Fit

This is a generic model designed as a starting point. Customization is expected, not a sign that something went wrong.
