How a construction company increased gross margin from 18% to 23% and released nearly $300,000 CAD from working capital

The company was completing more than $6 million CAD of construction work annually, but the numbers were not behaving the way management expected.

Monthly revenue averaged approximately $520,000 CAD. Yet gross margin was only about 18%, projects that looked profitable when quoted were frequently finishing below estimate, and almost $1 million CAD was sitting in accounts receivable.

There was another problem that was less obvious.

The company was receiving about 70 new enquiries every month, but new signed work averaged only around $460,000 CAD per month. The company was effectively completing work faster than it was replacing its backlog.

Management initially saw customer acquisition as the main challenge.

Our review suggested that acquiring more leads alone would not solve it.

The business needed to improve the economics of the projects it was already winning, shorten the path from enquiry to signed contract, control margin erosion after work began, and convert completed work into cash more quickly.

The company had revenue, but relatively little room for error

The contractor employed approximately 26 people across estimating, project management, administration, and field operations, in addition to subcontractors used across active projects.

Monthly revenue of about $520,000 CAD produced annualized sales of roughly $6.2 million CAD.

Direct project costs, including field labour, materials, subcontractors, equipment, and other job-specific costs, averaged approximately $426,000 CAD per month.

That left:

$520,000 CAD revenue – $426,000 CAD direct project costs = about $94,000 CAD gross profit

or approximately an 18% gross margin.

Operating overhead was about $78,000 CAD per month.

That meant roughly $16,000 CAD remained before financing costs and income taxes in a typical month.

The business was profitable, but the margin for mistakes was narrow.

A $15,000 CAD cost overrun on a project could eliminate most of one month's operating profit.

Understanding why those overruns were occurring became more important than simply increasing the number of projects.

Seventy enquiries were producing only four signed projects

The company's acquisition funnel initially looked healthy at the top.

It received approximately 70 enquiries per month from referrals, online marketing, previous customers, and other sources.

Roughly 30 appeared to be qualified opportunities.

About 14 progressed far enough for the company to prepare a meaningful estimate or proposal.

Only around four became signed projects.

The typical funnel looked like:

70 enquiries → 30 qualified opportunities → 14 estimates → 4 signed projects

Average project value was approximately $115,000 CAD.

Four signed projects therefore represented about:

4 × $115,000 CAD = $460,000 CAD of new contracted work per month

The company was recognizing around $520,000 CAD of monthly revenue but adding only about $460,000 CAD of replacement work.

If that continued, backlog would gradually decline.

The company was also spending approximately $14,000 CAD per month on customer acquisition and related marketing activities.

At four signed projects per month, the apparent acquisition cost was about:

$14,000 ÷ 4 = $3,500 CAD per signed project.

We did not recommend increasing the marketing budget immediately.

The existing 70 enquiries were already creating enough opportunities to investigate what was happening further down the funnel.

Some leads were disappearing while estimates were being prepared

We reviewed the path from initial enquiry to signed contract.

An interested prospect could speak with the company, wait for an initial review, arrange a site visit, wait for subcontractor or supplier information, receive an estimate, ask questions, request revisions, and then wait for a final price.

For more involved opportunities, average estimate turnaround was approximately 7 business days.

That delay had commercial consequences.

A construction customer rarely asks only one contractor for a price.

By the time the company returned with its proposal, some prospects were already discussing terms with a competitor.

We reorganized acquisition reporting around the entire funnel rather than raw lead volume.

Management began reviewing lead source, qualified opportunities, site visits, estimates issued, estimate turnaround time, signed contracts, project value, and eventual gross margin.

That last metric mattered.

A marketing source that produced five projects was not necessarily better than one producing three if those five projects consistently carried weaker margins.

Customer acquisition therefore became connected to project economics rather than being measured separately.

We also standardized the information collected before estimating began. Prospects who were not ready, had unrealistic budgets, or fell outside the company's target work could be identified earlier.

Estimators could spend more time on opportunities with a realistic probability of becoming profitable projects.

Winning the project was only half of the pricing problem

The next issue became visible when we compared estimated project margins with completed project margins.

The company commonly targeted margins above 20% when preparing estimates.

Actual gross margin across the business was closer to 18%.

When we reviewed completed projects, we found that the problem was not simply that estimators were quoting low prices.

Margin was also being lost after the contract was signed.

Consider a typical $115,000 CAD project.

At an 18% gross margin, the economics looked approximately like this:

Contract price: $115,000 CAD

Direct project cost: about $94,000 CAD

Gross profit: about $21,000 CAD

A relatively small estimating error could materially change that outcome.

An additional $4,000 CAD of labour and subcontractor cost would reduce gross profit from approximately $21,000 CAD to $17,000 CAD.

The project's margin would fall from about 18% to less than 15%.

Across several projects, those differences explained why company-level profitability was weaker than the quoted margins suggested.

Small estimating assumptions were becoming expensive on site

We reviewed where estimated and actual costs were diverging.

The pattern was not one dramatic failure.

Margin was being lost through smaller items accumulating during construction: labour taking longer than expected, differences between preliminary supplier allowances and actual costs, minor scope changes, subcontractor adjustments, and work proceeding before the financial effect of a change was fully documented.

A review of completed jobs showed that the gap between expected and final gross margin was commonly around four percentage points.

On a $115,000 CAD project, four percentage points represent:

$115,000 × 4% = $4,600 CAD

of gross profit.

Across four or five new projects every month, that became a significant amount of money.

We rebuilt the pricing review around both the original estimate and what happened after the job began.

Estimates separated major cost categories more clearly. Labour assumptions became visible instead of being buried in a total project figure. Subcontractor and material allowances were distinguished from confirmed costs. Contingency and project-specific risks were identified before the final price was approved.

We also introduced minimum margin expectations and clearer rules for reviewing projects that fell below them.

The objective was not to reject every lower-margin project.

A strategically important customer or project could justify a different decision.

The important change was that management could now see the tradeoff before committing resources.

A signed change order was worth more than a verbal agreement

Pricing discipline would not protect margins if the same discipline disappeared once construction started.

Change orders were an important example.

A client might request additional work on site. The project team wanted to keep the job moving, so smaller changes sometimes proceeded before pricing and written approval were completed.

Commercially, the risk was straightforward.

The company could incur the labour and material cost immediately while the revenue remained uncertain.

We introduced a more consistent change-management process.

The project team documented the requested change, estimated the cost and schedule impact, priced it, obtained approval where required, and then connected it to billing.

Urgent situations still required judgment. The process was not designed to stop construction every time conditions changed.

It was designed to prevent scope changes from disappearing inside the original project margin.

That helped move project profitability closer to the margin management had expected when the work was sold.

The projects themselves were being managed differently

Our operating review showed that the company had capable employees, but many project-management practices depended on individual habits.

One project manager maintained detailed notes.

Another relied heavily on email.

Site information might be recorded in one place while purchasing information existed somewhere else.

Project handoffs from estimating to operations also varied depending on who was involved.

This created recurring questions:

What exactly had been included in the price?

Which assumptions had the estimator made?

Which materials had been ordered?

Which client changes were approved?

What remained to be billed?

Who was responsible for the next action?

We mapped the project lifecycle from qualified opportunity to final collection.

The company then standardized the critical handoffs rather than attempting to document every possible construction activity.

The process covered estimate approval, project handoff, procurement, project-cost review, change management, progress billing, completion, and final closeout.

That gave different project managers a common operating structure without trying to eliminate the judgment required to run a construction site.

The reports arrived after the margin had already disappeared

The company already received monthly financial statements.

The problem was timing and level of detail.

A company-level income statement could report an 18% gross margin after the month ended.

Management needed to know which active project was moving toward 14% while there was still time to do something about it.

We designed a management reporting system around project-level and company-level KPIs.

The weekly operating review included:

Sales pipeline

How many qualified opportunities, estimates, and signed projects were in the pipeline, and what was their dollar value?

Backlog

How much contracted work remained to be completed?

Estimated versus forecast project margin

Was an active project's expected profitability moving away from its original estimate?

Labour and subcontractor variance

Were actual project costs tracking the assumptions used in the estimate?

Unapproved and unbilled change work

Was the company performing work that had not yet become billable revenue?

Schedule performance

Were projects progressing sufficiently to support the expected billing schedule?

Accounts receivable

How much billed work remained uncollected, and how old were those balances?

13-week cash forecast

Would upcoming collections support payroll, subcontractor payments, material purchases, taxes, and other expected cash requirements?

The dashboard changed the timing of management decisions.

A margin problem identified before a project was 40% complete was fundamentally different from discovering it after the final invoice.

Revenue and gross margin could now be separated

One of the most useful management changes was relatively simple.

Project managers stopped treating revenue progress as sufficient evidence that a project was performing well.

Consider two projects that each generated $100,000 CAD of revenue.

Project A required $78,000 CAD of direct cost and produced $22,000 CAD of gross profit.

Project B required $88,000 CAD and produced only $12,000 CAD.

The revenue was identical.

The economic result was not.

That distinction also affected customer acquisition.

Winning more work similar to Project B could make the company larger while consuming field capacity that might be better used on stronger-margin work.

Management therefore began connecting:

pipeline → price → estimated margin → actual project cost → final margin

instead of evaluating those stages independently.

Almost $1 million CAD had already been billed but not collected

Project margin explained profitability.

It did not explain why cash remained tight.

Accounts receivable were approximately $940,000 CAD.

At around $520,000 CAD of monthly revenue, that represented roughly 54 days of sales outstanding.

Construction companies naturally carry receivables because work is often billed progressively and customers do not necessarily pay immediately.

The issue was not the existence of receivables.

It was the amount of cash being financed by the contractor.

The company also had approximately $220,000 CAD of completed or substantially completed work that had not yet reached the normal billing cycle.

Together, billed receivables and unbilled work represented more than $1.1 million CAD between performing the construction and receiving the cash.

The company could report a profitable project while still financing labour, suppliers, and subcontractors for weeks.

Faster billing was as important as faster collection

Our cash-flow work therefore started before the receivable existed.

We reviewed the path from completed work to invoice.

Progress information did not always reach administration immediately. Supporting documentation sometimes had to be assembled after the billing period had already begun. Changes could remain unresolved and delay part of an invoice.

We aligned project reviews with billing cutoffs so that project managers knew what information administration needed and when it was required.

The objective was straightforward:

completed and billable work should become an invoice as quickly as contract terms reasonably permitted.

After billing, receivables were reviewed weekly by age, amount, customer, and responsibility for follow-up.

Management also distinguished between normal contractual payment timing and balances that genuinely required action.

A 13-week forecast changed how the company looked at cash

The company previously managed cash primarily through the current bank balance, expected large customer payments, and upcoming major obligations.

That approach becomes difficult in construction because cash moves unevenly.

A single week can contain payroll, supplier payments, subcontractor invoices, taxes, and equipment expenses while a major customer payment arrives several days later.

We developed a rolling 13-week cash-flow forecast.

The forecast incorporated expected collections from existing receivables, anticipated progress billings, payroll, subcontractor payments, materials, overhead, taxes, and other known cash requirements.

It did not predict the future perfectly.

That was not its purpose.

It showed management where assumptions mattered.

If a $180,000 CAD customer payment expected in week six moved to week eight, management could see the effect before it became a cash shortage.

Cash management became a forward-looking operating activity rather than a reaction to the bank balance.

What changed over the following nine months

The company implemented the changes progressively across estimating, project management, financial reporting, billing, and collections.

Marketing spending did not materially increase.

The business did not need to double lead volume or dramatically change the kind of construction work it performed.

The more important improvement was what happened to the opportunities and projects already moving through the company.

After approximately nine months, the operating picture looked like this:

Metric	Before	After
Monthly revenue	About $520,000 CAD	About $565,000 CAD
Gross margin	About 18%	About 23%
Monthly gross profit	About $94,000 CAD	About $130,000 CAD
Monthly operating overhead	About $78,000 CAD	About $84,000 CAD
Operating profit before financing and tax	About $16,000 CAD	About $46,000 CAD
New enquiries	About 70/month	About 72/month
Estimates issued	About 14/month	About 16/month
Signed projects	About 4/month	About 5/month
Monthly marketing spend	About $14,000 CAD	About $14,000 CAD
Acquisition cost per signed project	About $3,500 CAD	About $2,800 CAD
Average estimate turnaround	About 7 days	About 4 days
Expected-to-final project margin gap	About 4 percentage points	About 1 to 2 percentage points
Accounts receivable	About $940,000 CAD	About $760,000 CAD
Average receivable period	About 54 days	About 40 days
Unbilled completed work	About $220,000 CAD	About $105,000 CAD

The sales improvement was relatively modest.

Monthly revenue increased by around 9%, from $520,000 CAD to $565,000 CAD.

The profitability improvement was much more significant.

At the beginning:

$520,000 × 18% = about $94,000 CAD monthly gross profit

Afterward:

$565,000 × 23% = about $130,000 CAD monthly gross profit

Gross profit therefore increased by approximately $36,000 CAD per month.

Operating overhead increased by roughly $6,000 CAD as the company handled greater activity and normal cost increases.

Even after that increase, operating profit before financing and income taxes moved from around $16,000 CAD to approximately $46,000 CAD per month.

The company did not simply sell more.

It retained more value from the work it sold.

Nearly $300,000 CAD was also released from the cash cycle

Accounts receivable declined from about $940,000 CAD to $760,000 CAD.

That released approximately $180,000 CAD.

Unbilled completed work declined from around $220,000 CAD to $105,000 CAD.

That represented another $115,000 CAD moving more quickly toward billing and collection.

Together, roughly:

$180,000 + $115,000 = $295,000 CAD

was no longer tied up at the same point in the billing and collection cycle.

This was not $295,000 CAD of additional profit.

It was working capital that the business no longer needed to finance to the same extent.

The distinction was important.

Construction companies can fail while showing accounting profit if cash leaves the business substantially earlier than customer payments arrive.

Profitability and liquidity needed to be managed together.

Why the changes reinforced one another

The improvement did not come from a single intervention.

Better customer acquisition reporting helped the company focus estimating effort on opportunities more likely to become suitable projects.

Faster estimating helped more qualified opportunities reach a decision before they disappeared.

Pricing discipline improved expected margins.

Project-cost reviews and better change-order controls reduced the amount of that margin lost during construction.

Standardized operating processes made project information easier to transfer from estimating to operations and from operations to billing.

Management reporting made deviations visible before projects were finished.

Faster billing and stronger receivables management converted more of the accounting result into cash.

Each improvement strengthened the next one.

The business lesson

A construction company should not evaluate growth only by signed contract value or revenue.

Every new project creates several obligations at the same time.

It consumes labour and project-management capacity.

It requires materials and subcontractors.

It may require the contractor to spend cash weeks before receiving customer payment.

And if the project was priced incorrectly, winning it can reduce overall profitability rather than improve it.

The stronger question is therefore:

How much gross profit and cash does each project create relative to the field capacity, management attention, and working capital it consumes?

For this company, acquiring customers remained important.

But the larger opportunity came from connecting customer acquisition to estimating, estimating to project execution, project execution to reporting, and reporting to cash.

Questions for another construction business owner

1. How much contracted work are you adding each month compared with the revenue you are completing?
2. Do you compare the gross margin quoted at the beginning of a project with the margin forecast while the project is still active?
3. How much additional work is being performed before a change is properly priced and approved?
4. How long does it take from a qualified enquiry to a completed estimate, and how many good opportunities disappear during that period?
5. How much completed work is waiting to be billed?
6. Can you see your expected lowest cash position over the next 13 weeks before a collection delay creates a problem?

When a construction business is busy but margins or cash do not reflect that level of activity, the answer may not be more projects. Examining how work is acquired, priced, delivered, measured, billed, and collected can show where the economic value of those projects is being lost.
