Construction cost controlQuoted per project

Find the overrun while you can still fix it.

Most builds learn what they cost on the way out. Yours doesn't have to, whether you are putting up one house, running twenty sites, or costing someone else's build.

Scoped to your build and quoted per project, whether that is one house or twenty sites. Its own product and its own bill, with nothing to do with our property software unless you want it to be.

What you get

Your BQ, kept honest

Planned against actual, item by item. Every change kept, none overwritten.

Materials, delivery to wall

What arrived, what went out, what's still on site, with photos.

Wastage you can see

Losses recorded with a reason and a cost. No more mystery shortfalls.

Who was on site

Daily attendance by trade, casual and subcontracted kept apart.

Variations, properly signed off

Raise, review, approve, with the cost and time impact attached.

Budget alerts before the money's gone

Live cost against plan, per phase, with warnings while it still helps.

The week it changes

A build that tells you where it stands

Not a report at handover. A position you can look at on a Tuesday, while the decision still costs you nothing.

Deliveries counted in, not assumed

A goods-received note against the order, so twenty bags paid for and eighteen delivered is a discrepancy you find on the day rather than a shortfall you notice at the end.

Spend measured against the BQ

Consumption compared to what the works were measured at, element by element. Half the money at half the build means nothing on its own; against a quantity it means everything.

Variations with a running total

Each change carries its cost, its time impact and who approved it, plus the number nobody usually has: the contract sum plus every variation to date.

Labour recorded as it happens

Daily attendance by trade, casuals and subcontractors kept apart, so a wage bill can be reconciled to the days worked on your site.

Who it's built for

  • Building your own house

    The highest-stakes build most people ever commission, usually run on a notebook and trust. One project, quoted as one project, with the same cost control a contractor would use. You need nothing else we make.

  • A QS practice

    Measured quantities, valuations against progress, and variations with an approval trail a client can follow without a meeting. Taken on its own, with no portfolio and no agency account behind it.

  • Contractors running several sites

    Each site its own budget, its own record and its own quote, with the position across all of them in one place and no site able to quietly borrow from another.

  • Developers

    Cost against budget per phase, with the variations that moved it attributable to whoever approved them.

Getting started on a live site

You do not have to wait for the next project. Most accounts start mid-build, from wherever the records currently are.

  1. 1

    Bring whatever you have

    A priced BQ, a spreadsheet, or a stack of delivery notes. We start from the records that exist rather than asking you to reconstruct the last four months.

  2. 2

    Set the baseline together

    Elements, quantities and rates go in with you on a call, so the first budget-versus-actual is one you recognise rather than one you have to audit.

  3. 3

    Run one week in parallel

    Record a week both ways and compare. If the numbers disagree, that is exactly what you wanted to find out, and better now than at handover.

Background reading: what a bill of quantities is for, why materials go missing and how variations lose a budget.

Questions we get a lot

Do I need to be a property agency?

No. This is its own product with its own customers: someone costing their own house, a QS practice, or a firm running twenty sites. It needs no agency account behind it.

Is it only for big contractors?

No. An account can be one person or a whole firm with roles per project, and it is quoted on the build rather than on how many of you there are. Someone putting up a single house pays for a single house.

Do you pay my suppliers or my fundis?

No. Domexa Technologies records what you spent so the numbers are right. You pay people yourself, as you always have.

What does it cost?

It is quoted per project, on the scope of the works, and billed on its own separately from anything else we make. Not a monthly seat licence: a build has an end, and so does what you pay for it. Tell us what you are putting up and we'll quote you straight.

Show us your site, we'll show you the numbers.
