What makes it hard to control costs without estimating software?

Controlling costs on a building project sounds straightforward enough.

Work out what the job should cost. Keep an eye on what you’re spending. Make sure there’s enough left at the end to deliver the profit you expected.‍ ‍

The difficulty is that good cost control depends on having good information in the first place.‍ ‍

And without estimating software, that information can quickly become fragmented, inconsistent or out of date.

Cost control starts with the estimatE ‍

The estimate isn’t simply a figure you give to the customer.

‍ It’s the financial blueprint for the job.

It should tell you what materials you expect to need, how much labour is involved, what plant and subcontractors will cost, what overheads need to be recovered and what profit you expect to make.

‍If those numbers aren’t properly calculated at the beginning, controlling the costs afterwards becomes much harder.

‍You’re effectively trying to manage the job against a moving or incomplete target.

So let’s look more closely at what can go wrong if you don’t use professional estimating software…

Manual calculations create more opportunities for mistakes

Spreadsheets can be useful. But the more complicated the project becomes, the more formulas, cells, quantities and rates there are to manage.

One wrong formula or missed item can alter the profitability of the job.

And calculations are only part of the problem.

Someone still has to decide what needs to be included in the first place.

Have you allowed enough labour?

Have you included waste?

Have you remembered fixings, sundries and plant?

Are your overheads properly recovered?

Have you allowed for contingencies where appropriate?

Small omissions across dozens or hundreds of cost items can become a sizeable hole in the job.

Your prices can become out of date

Materials prices change.

Labour rates change.

Subcontractor costs change.

If your estimating process relies on manually maintaining spreadsheets or referring back to old quotes, it becomes very easy to price today’s job using yesterday’s numbers.

That difference may look small against an individual item.

Multiply it across an extension, loft conversion or new build and it can have a serious effect on margin. ‍

Estimating software such as EstimatorXpress gives you a structured pricing system, with PriceTracker+ providing regular material price updates, helping you build estimates using more current information.

Changes take longer to deal with‍ ‍

Building projects change.

A customer upgrades a specification. A quantity changes. Another room is added. The construction method alters. ‍

With a manual estimate, one change can mean finding the relevant figures, recalculating quantities and checking whether anything else has been affected.

That takes time.

More importantly, it increases the chance that something gets missed.

With estimating software, the information is structured. Changes can be made within the estimate and the changes cascade. Think of the time saved. And the impact of the changes becomes much easier to understand.

It’s harder to see where the money is going

Good cost control isn’t simply about knowing the total cost of a project.

You need to understand what sits underneath it.

How much is labour? ‍

How much is materials?

What have you allowed for subcontractors?

What overheads need recovering?

Where is your profit? ‍

Detailed estimating software breaks the project down into meaningful cost areas.‍ ‍

EstimatorXpress gives you a dashboard so you can assess the profitability of your various jobs and start making a judgement about the kind of work you want to do.

there’s no professional audit trail

Without a digital estimate, you’re instantly going to struggle to audit the job - you just won’t have the detail.

Not every builder works this way, but many need to adhere to certain frameworks and are required to provide traceable breakdowns.

That could be New Engineering Contracts (NEC) or Joint Contracts Tribunal (JCT). They’re both standard-form construction contracts used in the UK.

Could you provide the Quantity Surveyor type checks?

Forecasting becomes guesswork

One of the biggest advantages of a properly constructed estimate is the ability to look ahead. ‍

What should this stage of the job cost? ‍

When will materials be required?

When should money be coming into the business?

What happens to the expected profit if costs increase?

Without structured estimating information, those questions become much harder to answer.

And that can mean problems are only discovered after the money has already been spent.

More estimating admin means less cost management

There’s another cost that’s easy to overlook: your time.

If hours are spent building spreadsheets, checking formulas, looking up prices and repeatedly recalculating jobs, that’s time that can’t be spent analysing the numbers or managing the project.

Estimating software automates much of the repetitive work.

EstimatorXpress, for example, uses hundreds of purpose-built estimating calculators to help calculate the labour, materials and other costs required for residential building projects.

You enter the project information. The software does much of the heavy lifting.

That leaves you with more time to consider the decisions that actually affect profitability.

So, does estimating software help control building costs?

Yes - because it gives you a much stronger starting point.

It doesn’t stop material prices changing.

‍It doesn’t stop customers changing their minds.

And it doesn’t remove the need to manage a building project carefully.

What it does is give you structured, consistent and detailed cost information on which to base those decisions. ‍

Instead of trying to control costs retrospectively, you can understand where the money is expected to go before work starts - and spot more quickly when reality begins to move away from the plan.

Because ultimately, cost control doesn’t start on site. It starts with the estimate.

EstimatorXpress helps residential builders estimate extensions, loft conversions, renovations and new builds in detail, using hundreds of ready-made estimating calculators, regularly updated material prices and built-in tools for overheads, profit, contingencies and project reporting.

The better you understand the numbers before the job starts, the better chance you have of protecting them once it does.
