The GC That's Quietly Costing You Money

Last updated: September 2026

Could you name your most profitable GC right now and back the answer with data?

In RiffleCM’s August 2026 survey of 200 U.S. subcontractors, 41% could. Another 44% could name a GC, but said the answer was gut feel. The remaining 15% did not know.

That is the difficulty with relationship-level profitability. Most subcontractors eventually know whether an individual job made money. Far fewer have a reliable view of what all the work for one customer adds up to. When that picture finally becomes clear, the result is often less favorable than the relationship felt along the way.

In August 2026, RiffleCM surveyed 200 U.S. subcontractors through Pollfish, an independent panel, with general contractors screened out; full methodology appears in The Profitability Blind Spot: What 200 Subcontractors Told Us About Knowing Their Numbers; RiffleCM builds software for subcontractors, including profitability tracking, and the numbers are reported as they came back.

1. The claim and the number

When asked directly whether they track profitability by GC or customer, 51% said they do it with real numbers. Another 30% said they track profitability job by job only, 16% rely mostly on gut feel, and 3% said they do not track it consistently.

At first glance, that puts about half the market on solid ground. The next question made the picture less tidy.

Among the respondents who said they track customer profitability with real numbers, 43% could not name their most profitable GC and back the answer with data when asked directly.

That gap is more useful as a systems finding than as a judgment about how carefully a subcontractor runs the business. Job-level information can be accurate while remaining difficult to assemble into a relationship-level answer. A company may know exactly how several projects performed without having one reliable answer for the GC behind all of them.

That distinction matters because customer history shapes future invitations, pricing conversations, and which opportunities receive estimating capacity. A stack of profitable-looking individual jobs can still add up to a weaker relationship once the full history is considered.

The broader benchmark set is available in Subcontractor Profitability Statistics 2026.

2. What running on gut feel costs

Instinct built plenty of good subcontracting businesses.

Owners and PMs learn which GCs communicate clearly, which teams create schedule churn, which customers keep work coming, and which relationships usually feel worth pursuing. That knowledge carries real value. Its limits become clearer when the question shifts to what the relationship has actually earned across all of its jobs.

Sixty-one percent said a GC relationship they had considered a good one eventually turned out to be losing them money. For 28.5% of the full sample, that discovery had happened more than once.

Another 27% had wondered whether a relationship was losing money. Only 12% said they were confident their systems would catch it.

Taken together, 88% had either been burned by a relationship they misjudged or could not confidently rule out that it was happening.

The sharpest cut comes from the group that said it already tracks profitability by customer with real numbers. Among those respondents, 67% had still discovered a GC relationship that was losing them money.

That result separates two capabilities: tracking something and seeing it in time. A customer-level answer can become available after enough jobs are closed and reconciled while arriving too late to influence earlier bids, pricing assumptions, or the amount of attention a relationship receives.

This is why customer profitability analysis in construction is harder than it sounds. The decision is often being made while the evidence is still scattered across jobs.

3. Who actually knows this number

Company size produces a mixed picture rather than a smooth progression toward better customer-level visibility.

Among firms under $1 million in annual revenue, 35% could name their most profitable customer with data. The figure rose to 50% among firms at $1 million to $3 million, then moved back to 41% for $3 million to $10 million and 39% for $10 million to $25 million.

The largest revenue group came in at 67%, with an important caveat: the over-$25-million cell contained only nine respondents. That result is directional and should be treated cautiously rather than used as a stable benchmark for large subcontractors generally.

The middle revenue bands stay fairly flat. The largest group is the only band that stands well above that middle cluster, and its small sample limits how much weight the difference can carry.

Owners show the same exposure. Among the 29 owners and presidents in the sample, 72% said they had discovered that a GC relationship they thought was good was losing them money. The subgroup is too small to carry the section, so it works best as supporting evidence.

Commercial mix adds another view. Among respondents whose work is mostly commercial, 36% could name their most profitable GC with data, compared with 44% among residential-majority respondents. The commercial-majority subgroup contained 75 respondents.

In this sample, the businesses most centered on GC relationships were less likely to know their top relationship from data. The survey shows that difference without establishing why it exists.

4. Why the number is hard

Job profitability and customer profitability answer different questions.

A job report can tell you whether one project held the margin in the estimate. Customer-level profitability requires the results of every project for the same GC to be considered together.

That view spans work that closed at different times, ran under different PMs, carried different margins, and absorbed different amounts of administrative attention. Costs that weaken a relationship can also look small when they appear one project at a time.

The survey gives a useful picture of those pressures. When respondents were asked which GC behaviors cost them the most margin, disputed or unpaid change orders ranked first at 49.5%. Slow pay followed at 32.5%, and retainage held too long came in at 28%.

These figures are reported as survey findings only.

They also help explain the structural problem. Job profitability typically sits in accounting one project at a time. Relationship profitability requires those jobs to be viewed together, including margin pressures that may repeat across several projects for the same customer.

One difficult project may be an exception. Several modest leaks across a string of otherwise decent jobs can create a very different customer-level result.

Gut feel has a hard time weighting all of that consistently. People remember the large win, the painful project, the easy PM, or the customer sending the most invitations. A relationship-level financial view has to account for each job according to what actually happened.

5. What knowing it changes

Knowing which customers actually make money changes the context around the next opportunity.

A GC that produces strong results across several jobs gives an estimator different evidence from one where awarded work repeatedly gives margin back after the bid. That history can inform bid decisions, relationship pricing, and which opportunities receive attention when estimating capacity is tight.

It also gives job results somewhere useful to go. Individual project performance becomes evidence for the next customer decision instead of remaining only a closeout record.

This is where job profitability and customer profitability connect. One describes the economics of the project. The other puts that project into the history of the relationship.

FAQ

How common is customer-level profitability tracking among subcontractors?

In RiffleCM’s August 2026 survey of 200 U.S. subcontractors, 51% said they track profitability by GC or customer with real numbers. Another 30% said they review profitability job by job without rolling it up by customer.

How often do subcontractors discover that a customer relationship is losing money?

Sixty-one percent said a GC relationship they had considered a good one eventually turned out to be losing them money. That had happened more than once for 28.5% of the full sample.

Why can customer profitability be harder to see than job profitability?

Job profitability is usually reviewed one project at a time. Customer profitability requires the results of every job for the same customer to be viewed together, including repeated margin pressures such as slow pay, disputed change orders, and retainage.
