E&O Insurance Reporting for
‍Architecture and Engineering Firms

The Annual Scramble Nobody Talks About

E&O insurance renewal is one of the most consistent administrative pain points in A/E practice — and one of the least discussed. Every firm goes through it. Almost nobody has a system for it.

The underwriter needs revenue data summarized by project type category. Gross billings. Subconsultant costs broken out. Net professional fees — the number the premium is actually rated on. Three years of data, typically. The five largest clients. A breakdown by client type and contract type. Claims history.

Most of that information exists somewhere in the firm's records. The problem is where it exists — scattered across invoices, project files, accounting systems, and memory. The office manager who handles renewal every year is not pulling from a single organized source. She is reconstructing the picture from whatever she can find, calculating the category splits as best she can, and hoping the numbers hold up when the underwriter asks a follow-up question.

The reconstruction is slow because the underlying data was never organized for this purpose. Projects were opened without a category tag that matches the underwriter's classification list. Billings were tracked at the project level without a mechanism to group them by project type. Subconsultant costs lived in the accounting system, separately from the billing records. Pulling the picture together means crossing three systems, making judgment calls about which projects belong in which categories, and doing the math by hand.

Then the renewal comes around again next year — and the reconstruction starts over.

The firms that handle renewal efficiently are the ones that solved the organization problem before renewal arrived. When every project is tagged with the underwriter's category at intake — one field, populated when the project is opened — the renewal report is not a reconstruction. It is a date range selection and an export. BaseBuilders summarizes all project activity within the reporting period by category, producing Gross, Subs, and Net figures for each category automatically.

The setup is one-time. The report runs every year in minutes. The data your broker needs to go to market — whether renewing with your current carrier or shopping competitively across the field — is ready before the conversation starts.

What E&O Underwriters Actually Need — and Why It's Harder to Produce Than It Should Be

The E&O renewal application asks for straightforward information: how much did your firm bill last year, and what kind of work was it? In practice, producing that information accurately is more involved than it appears.

Revenue categorized by project type

The underwriter's primary concern is understanding the firm's risk profile — what kinds of projects it works on, in what proportions, and how those project types have changed over time. A firm that does primarily commercial office work has a different risk profile than one that does significant residential, healthcare, or infrastructure work. The application asks for revenue broken down by category so the underwriter can assess the profile.

The categories are not standardized across carriers. Each underwriter maintains its own classification list, and the categories vary meaningfully — one carrier may combine commercial and retail into a single category while another separates them; one may have a specific category for government work while another groups it with institutional. The firm's project data needs to be organized against its carrier's specific list, not a generic industry taxonomy.

Gross billings, subconsultant costs, and net professional fees — separately

The underwriter needs three numbers for each category, not one. Gross billings — the total invoiced to clients. Subconsultant costs — the amount paid to subconsultants whose fees were passed through or marked up and billed to the client. Net professional fees — gross billings minus subconsultant costs — which is the figure the premium is actually rated on.

This distinction matters because a significant portion of what many A/E firms bill consists of subconsultant pass-throughs — structural engineers, MEP engineers, and civil engineers hired by the prime and billed to the client. The prime firm's own professional services — the work that generates the liability the E&O policy covers — is the net amount. Firms that report gross billings without subconsultant separation are overstating their net professional fee base and potentially overpaying their premium.

Three years of data

Most E&O applications request three years of data — the current reporting period and the two prior periods. This gives the underwriter a trend view of the firm's project mix and revenue, not just a snapshot. A firm that shifted significantly toward higher-risk project types in the current year will show that shift more clearly in a three-year view than in a single-year report.

Why reconstruction is the default — and why it doesn't have to be

The reason E&O renewal is painful for most A/E firms is that the data required for renewal was never organized with renewal in mind. Projects were set up in the project management system without a category tag that matches the underwriter's classification list. Revenue was tracked at the project level, but there was no mechanism to group it by project type. Subconsultant costs were managed in the accounting system separately from the billing records.

At renewal, the office manager is assembling a picture from multiple sources — billing records, project files, the accounting system — and calculating the category splits from scratch. The process takes days and produces an answer that is accurate enough, but not documented enough to answer follow-up questions confidently.

The alternative is tagging projects at intake with the underwriter's category — one field on the project record, populated when the project is opened. When that tag exists, the renewal report is a filtered export that runs in minutes and produces the same organized data every year.

Using Clean Data to Shop Competitively — Not Just Renew Compliantly

Most A/E firms renew their E&O policy with the same carrier every year. Not because the carrier is necessarily the best option — but because pulling together the renewal data for one application is already painful enough. Shopping multiple carriers means doing that work two or three times simultaneously.

That calculus changes when the data is already organized.

A firm with a properly configured BaseBuilders renewal report can produce the complete renewal data package in a single export. That same export can be handed to two or three competing brokers simultaneously — each shopping the firm's book across their carrier relationships and returning with competitive quotes.

The dynamics of the E&O insurance market reward firms that shop. There are approximately 60 carriers in the A/E professional liability space. Pricing varies meaningfully across carriers for identical risk profiles. Brokers who specialize in A/E professional liability have relationships across the market and can identify pricing differences that a firm renewing with a single carrier every year never sees.

The barrier to shopping has always been the data — most firms don't have it organized well enough to hand to multiple brokers without significant additional work. When the data exists as a saved report in BaseBuilders, shopping becomes as easy as renewal. The firm enters the renewal conversation armed with organized data, a clear picture of its own risk profile, and the ability to obtain competitive bids from multiple sources without tripling administrative burden.

Fees vs. Billings vs. Income — Which Number Does Your Underwriter Want?

One of the most common sources of confusion in E&O renewal reporting is which revenue figure the underwriter is asking for — and why the answer matters.

Fees are the contracted amounts — the fees the firm agreed to deliver services for, as stated in the contract or proposal. For a multi-year project that spans reporting periods, the contracted fee may not reflect what was actually invoiced or collected during the specific renewal period. A $500,000 design fee contracted in year one but billed across three years produces a distorted picture if reported as a single-period revenue figure.

Billings are what were actually invoiced to clients during the reporting period — the amounts that appeared on invoices, regardless of when the underlying work was performed or when payment was received. Billings are a more accurate reflection of the firm's activity during a specific period than contracted fees.

Income is what was actually collected — payments received during the reporting period. Income is the most conservative measure and the most accurate reflection of the firm's realized revenue for the period.

Most underwriters ask for billings or income rather than contracted fees precisely because fees distort multi-year projects. A firm that is mid-design on a large project at renewal time should report what it actually billed during the period — not the full contracted fee for the project.

BaseBuilders supports all three measures — Net Fees, Net Billings, and Net Income — in the renewal report output. The right choice depends on what the specific underwriter asks for. When in doubt, ask the broker. The broker knows what the carrier wants and can clarify before the report is run.

What Good E&O Renewal Preparation Looks Like

A firm that handles E&O renewal well can answer these questions without a reconstruction exercise:

• What were gross billings by project category for each of the past three renewal periods?
• What were the subconsultant costs by category for the same periods?
• What were the net professional fees by category for each period?
• Who were the five largest clients by revenue in the current period?
• What was the breakdown of client types — government, private owner, developer, contractor?
• What was the breakdown of contract types — AIA standard, firm's own contract, letter agreement?

A firm with BaseBuilders configured for E&O reporting can answer all those questions from a single report run. A firm without that configuration is assembling the answers from invoices, project files, and accounting records — every year, from scratch.

The firms that handle renewal efficiently aren't doing more work than those that don't. They did a small amount of setup work once — creating the category field, loading the underwriter's list, tagging projects at intake — and that work produces the renewal report automatically every year thereafter.
