An unprofitable project rarely looks like a loss-maker on the day the contract is signed. The estimate has figures in it, the crew is busy, the customer pays on schedule, and purchasing is underway. Yet when the project ends, less money is left than expected, and its profitability has been eroded by small “losses” that nobody has brought together into one picture.
The problem is that a loss-making project almost always develops from familiar issues: work was left out of the estimate, the payment arrangement was risky, changes were agreed without recording their price, staff expense advances slipped out of control, or direct costs were not separated from overhead.
Below is a practical way to spot unprofitable projects before they become a habit. It applies to construction and renovation, as well as any project-based business where profit is earned within individual projects.

Why is an unprofitable project easy to miss?
A common scenario: a project “feels” profitable. The customer is happy, the scope is growing, and extra work keeps coming in. Meanwhile, money goes out in small amounts: a delivery, some consumables, an advance to a tradesperson, an urgent tool hire. Each transaction looks insignificant, and monitoring project profitability turns into a once-a-month check.
Another scenario is a project built on verbal agreements. The project manager is sure “we will cover that with an addendum later”, the site foreman is sure “the customer understands”, and the buyer is sure “the materials are needed for the actual work”. When figures are not backed by documents and recorded events, an unprofitable project often becomes apparent only after handover.
A third reason is confusing profit with cash. There may be money in the bank account while the project is still making a loss: some payments belong to another project, some expenses have not been entered, and some amounts owed to the crew and subcontractors have not been recorded. It helps to consider this through the lens of a cash flow gap: cash reflects timing, while project profitability reflects the overall result.
Which figures should you calculate to assess project profitability?
Three levels of calculation are enough to spot a loss-making project early. You do not need a financial model with twenty tabs.
1) Planned gross profit (margin) for the project. The formula is simple: planned revenue minus direct costs. Direct costs include materials, subcontracting, piece-rate pay, delivery, equipment hire for the job, and consumables that genuinely belong to the project. If the margin is small, any mistake can put the project at risk. The 101 blog discusses this as the “cheap money” phenomenon; a useful read is low margins and the reasoning behind business decisions.
2) Overhead and management expenses. Even a carefully managed project still needs an office, a manager, bookkeeping, marketing, transport, and communications. These costs are often “invisible” in the estimate, so project profitability may feel healthy while the company generates no net profit.
Gross profit is an amount of money; gross margin = gross profit / revenue × 100%. Forecast project result after overhead = planned gross profit − overhead and management expenses allocated to the project. Project profitability in the calculations below means this result as a share of planned revenue: forecast result / planned revenue × 100%. This forecast result is before tax and is not net profit. When revenue is zero, the corresponding percentage is undefined.
3) The payment schedule: who pays and when. A profitable project can run into cash trouble if customer payments are late while purchases and wages must be paid as work proceeds. This arrangement can create debts and penalties even when the margin is healthy.
An estimate based on guesswork increases the risk. It is also useful to keep the structure of an estimate and the customer’s expectations in mind: whether you need an estimate for an apartment renovation and what it actually provides (in Russian).
Early warning signs of a loss-making project
An unprofitable project rarely falls apart because of a single event. More often, repeated warning signs gather momentum. The good news is that these signs can be seen in the first few weeks if you compare planned and actual figures and check whether agreements are being recorded and followed.
| Warning sign | What to check | What it tells you |
|---|---|---|
| The estimate relies on broad, lump-sum items | Whether it is broken down by stage and price-list item, and who is responsible for quantities | A risk of missed work and additional costs during the project |
| Frequent changes, with extra work recorded late | How changes are documented: an acceptance certificate, a contract addendum, or an accounting event | The project is drifting into “free” work |
| Staff expense advances and small purchases grow without limits | Whether rules specify who can buy, the spending categories, and receipt requirements | Margins are falling unnoticed |
| Customer payments arrive after mandatory payments fall due | A weekly calendar of receipts and payment obligations | A risk of cash flow gaps and debt |
| Deadlines keep moving and downtime is not recorded | The reasons for downtime and who pays for the consequences | The project can become loss-making even with a sound estimate |
Another warning sign is the feeling that “the profit is there; it will just come later”. In practice, this often means hope has taken the place of profit: payment for extra work has not been agreed, some expenses are scattered across chats, amounts owed to subcontractors have not been reconciled, and purchases are not linked to the project. For a useful reference on “measuring reality”, see honest accounting and why actual events need to be recorded (in Russian).
A quick project check before work begins
If you have one evening to prepare, follow this order: check the estimate, then the money, then the rules for changes. This saves stress: there is little point building a payment schedule around an estimate full of gaps.
- Build the estimate from the price list and project stages, without grouping everything into a single “turnkey” item.
- Add the project’s direct costs: materials, subcontracting, piece-rate pay, delivery, and hire costs.
- Allow for overhead: a percentage or a fixed monthly amount reflecting what the project actually uses.
- Calculate the planned margin and project profitability as a percentage.
- Build a weekly calendar of customer receipts and mandatory payments.
- Check the rules for changes: who approves them, how the price is recorded, and the deadlines for signing.
- Set limits for staff expense advances and purchasing: who may spend, on what, and with which supporting documents.
In construction and renovation, it helps to keep two separate outcomes in mind from the start: “profit on the project” and “enough cash each week”. A weak payment schedule often forces a business to borrow, put pressure on the crew, or delay purchases. For this, see how to avoid a cash flow gap in a construction company.
What should you do if work is underway and margins are falling?
With an unprofitable project, the habit of “just getting through to the end” is dangerous. A project-based business benefits from decisions based on warning signs rather than emotion. Stop-loss rules help here: decide what to do as soon as the margin falls below the level your company considers safe.
Start by investigating the causes rather than looking for someone to blame. If costs have risen, identify the category: materials, subcontracting, rework, logistics, or downtime. If revenue is behind plan, check the agreed scope, the work completed, and the conditions for recognizing revenue: have changes been documented and the necessary acceptance certificates signed? Check cash collections separately: payment dates, overdue amounts, and how payments are tied to stages. A payment delay affects the cash schedule and does not, by itself, mean recognized revenue or profit has fallen.
Next come negotiation and disciplined recordkeeping. Three actions often help: renegotiate stages and payments, document the extra work together as a package, and tighten limits on staff expense advances and purchasing. It sounds dull, yet this is how control is restored.
If you need a starting point for finding specific ways to increase profit, read where to find profit growth opportunities in a project-based business (in Russian). It offers plenty of practical reasoning that can be applied to construction and renovation.
How can you make monitoring routine with the 101 App?
Once you have more than one project, manually monitoring project profitability quickly becomes an exercise in reconstructing the past: who paid, who bought what, which costs belong to the project, where the receipt is, and where the acceptance certificate is. One principle helps in practice: keep the accounts within the project, record actual events as they happen, and compare the plan with the actual figures.
This is the approach supported by the 101 App: each project has its own balance, expenses and payments are linked to the project, and profit, debt, and staff expense advances are visible. When figures are updated as work proceeds, you can spot an unprofitable project before it ends.
Analytics is especially useful when you have many projects and want to see where profit is rising while revenue falls, and where the reverse is happening. For that, read what it means when profit rises and revenue falls (in Russian): it helps you stop judging projects by turnover alone.
If you want to work through the process using your own projects and establish rules for recording estimates, changes, planned and actual figures, and staff expense advances, it is easier to review the key screens with an expert during a product demonstration. This helps you develop the habit of assessing project profitability through figures rather than guesswork.
