Software built for how construction really runs

Your best information is out on site, and it gets to the office too late.

Construction software development means building software around how your business really runs a job — your estimating, the flow between the office and the site, and the accounting and supplier systems you already use — so it supports the work instead of forcing your team onto a generic tool.

On most jobs the office and the field run on two different systems: paper dockets, group texts and photos on one side, dashboards and accounts on the other. Someone re-types the field notes into the system, job costs surface weeks late, and half your crew quietly goes back to paper because the app spins with no signal. You end up managing yesterday’s job instead of today’s.

Avaib closes that gap. We put senior people who understand both construction and integration on your project, design the office-to-site flow first, and build a field app the crew will actually use. One accountable team, code you own, at a cost-effective senior rate.

What we build for construction

The software that runs a job from bid to handover.

From the estimate to the final defect list, we build the software that keeps the office and the site working from the same picture. Some of it is custom-built, some extends what you already run.

Construction & project management platforms

One place for drawings, documents, RFIs, daily logs, change orders and progress — shaped around how your projects actually run, not a generic template that leaves half your process in spreadsheets.

Estimating & takeoff tools

Estimating and quoting built around your own rates, assemblies and margins, so bids go out faster and more accurately, and the numbers you win on flow straight into the job instead of being re-keyed.

Field & site apps (offline-first)

Apps the crew will actually use on site — daily reports, photos, timesheets, checklists, variations and defects — built to work with no signal and sync the moment a bar of reception returns.

Job costing & accounting integration

Live job costing that ties labour, materials, subcontractors and change orders together and syncs cleanly with QuickBooks, Xero or Sage, so you know whether a job is making money while you can still act on it.

Scheduling & subcontractor coordination

Scheduling, resource planning and subbie coordination that replace the whiteboard and group texts, so the right crew and trades are on the right site with the right information.

Safety, compliance & defect tracking

SWMS and inductions, safety checklists, certifications and defect and snagging lists tracked in one system built for the trade doing the work, not bolted onto a platform built for the head contractor.

Why construction software goes wrong

The site knows before the office does — but the office pays the bill.

This is how a capable, hard-working firm still ends up managing every job a week behind. It is the most common way construction software falls short, and everything about how Avaib builds is designed to avoid it.

01

The work happens on site, in real time

Costs are committed, hours are worked, materials are used and problems appear out on the job — hours or days before any of it reaches a screen in the office.

02

The office is always managing yesterday

Field notes get texted, photographed or scribbled on paper, then re-typed by someone in the office. By the time the numbers are in the system, the job has already moved on.

03

You find out a job lost money after it is built

When job costing lands weeks late, the profit leak is invisible until it is too late to fix. On single-digit construction margins, catching it in week two instead of at handover is the whole difference.

Construction firms do not lose margin because they lack effort. They lose it because the information reaches the office after the work, the money and the mistakes have already happened. Close the gap between the site and the office, and the software starts protecting your margin instead of reporting on it.

Where the money and the hours disappear

Two systems, one job, and a gap in the middle.

The office and the field usually run on completely different systems. The gap between them is where double entry, missed variations and late job costing live. Custom software is the bridge across it.

In the office

Clean, structured, always a step behind reality

  • Clean dashboards and reports
  • Invoices, budgets, forecasts
  • Accounting and payroll
  • Client and contract updates
The gap
Re-typing, missed variations, job costs that arrive weeks late

On the site

Where the work, the cost and the problems actually happen

  • Paper dockets and photos
  • Group texts and phone calls
  • A spinning app with no signal
  • Timesheets on the back of a hand

We do not ask the crew to work like the office, or the office to chase the site. We build the bridge — one system where the field records once and the office sees it live — so the gap simply closes.

What good looks like

One connected job, from the site to the accounts.

When the field records once and the office sees it live, the whole business gets calmer and more profitable. Here is what that changes.

The field records once, the office sees it live

Crews capture hours, photos, materials and variations on site in an app they will actually use, and it flows straight to the office — no re-typing, no double entry, no paper going missing on the way.

Job costs you can act on, not autopsy

Labour, materials, subcontractors and change orders roll up as they happen, so you can see whether a job is making money while there is still time to do something about it.

Works where the job is, signal or not

The site app keeps working in a basement, a rural block or behind concrete, and syncs the moment reception returns, so bad coverage never costs you the day’s records.

The tools you already run, connected

We wire the new software to QuickBooks, Xero, Sage or your payroll and supplier systems, so estimates, costs and invoices move automatically instead of being entered twice.

Variations and defects that do not slip

Change orders, site instructions and defect lists are captured against the job the moment they happen, so nothing gets built for free and nothing gets missed at handover.

Software you own outright

The code, the data and the integrations stay yours, so the system that runs your jobs is never held to ransom by a platform vendor or a per-seat price that climbs every year.

Where a job leaks, and where we seal it

Every stage of a job, from bid to handover.

Off-the-shelf tools tend to stop talking to the next one at each seam of a job. Here is where the data drops out along the way, and what connected software gives back at each stage.

Bid & tender

Bids live in email and spreadsheets, disconnected from the job that follows.

Capture every enquiry and bid in one place, ready to become a live job the moment you win it.

Estimate & takeoff

The winning numbers get re-entered by hand into the project and the accounts.

Estimates flow straight into the budget and job costing, so you build against the numbers you actually won on.

Schedule & resource

Crews and trades are coordinated on a whiteboard and by group text.

Schedule people, trades and equipment in one view everyone can see and act on.

Site execution

Hours, photos, materials and issues sit on paper until someone types them up.

The crew records it once on site, offline if needed, and the office sees it live.

Job costing

Real costs surface weeks late, long after you could have acted on them.

Costs roll up as they happen, so profit leaks show while you can still fix them.

Variations & change orders

Verbal changes get built and only argued over at invoice time.

Every variation is logged against the job the moment it happens, so nothing is built for free.

Defects & handover

Snagging lives on a clipboard and a dozen photos in someone’s phone.

Defects are tracked to close-out and handover is a clean, documented finish.

The concerns, answered

What worries builders and contractors about a custom build, and how we handle it.

These are the real concerns we hear before a construction project starts. Here is exactly how Avaib takes each one off the table.

"We are paying for a platform built for big head contractors, and using a tenth of it."
Enterprise construction platforms are priced and built for the general contractor on a large job, so a builder or subbie ends up paying for modules they never open. We build only what you actually run on, so you are not renting bloat, and the per-seat price does not climb every year for features you never use.
"The crew won’t use it — they add a login and go straight back to paper."
Software gets abandoned when it is built for the office and handed to the field with nothing in it for the crew. We design the site app around what the crew needs to get through the day — fast, offline, a few taps — so it gives them something back and the data actually gets captured.
"Half our sites have no signal, and the app just spins."
Not every job site has coverage — basements, rural blocks, behind concrete. We build the field app offline-first, so it keeps working with no signal and syncs the moment a bar of reception returns, rather than timing out and sending the foreman back to paper.
"We don’t know if a job actually made money until it’s finished."
That is a data-flow problem, not an accounting one. We wire live job costing to the field and to your accounts so labour, materials, subs and variations roll up as they happen, and you see the margin while there is still time to protect it, not weeks after handover.
"Our software and our accounting package never really talk."
Shallow, one-way syncs are where construction tools usually fall down — change orders and sub payments still get keyed in twice. We build proper two-way integration with QuickBooks, Xero, Sage or your payroll, so the numbers move once and match on both sides.
"A generic developer will not understand how construction actually runs."
Progress claims, retentions, variations, back-charges, SWMS, defect liability periods — construction is full of specifics a generic build gets wrong. Our senior specialists have built project, estimating, field and job-costing software before, so those realities are designed in from the start, not discovered on site.

Why Avaib

Why choose Avaib for construction software development.

Plenty of teams can write code. Fewer design the office-to-site flow and the accounting integration as the main event before they start. Our model is built to bring both to your jobs.

Tower cranes over a construction site at dusk

Two decades of building operational software

Since 2004 and more than 600 projects, including project, estimating, field and job-costing systems, so the messy reality of running construction jobs is understood before the build starts.

Built for the field as well as the office

We design the site app around what the crew will actually use — fast, offline, a few taps — because the tool only pays off if the people on site keep the data flowing.

Integration with the tools you already run

Proper two-way links to QuickBooks, Xero, Sage, payroll and suppliers, so estimates, costs and invoices move once and match, instead of being entered twice.

Cost-effective senior expertise

Senior engineers from around USD 25 per hour, the same capability Australian, US, Canadian and Middle-East firms charge a fortune for, at a fraction of the price.

AI-accelerated delivery

Our senior engineers use advanced AI coding tools to move through the build faster, directing and reviewing every step, so your construction software ships sooner without cutting corners on the details that decide a project.

One accountable team with real QA

One senior team owns your build end to end, tested by a dedicated QA department against real site scenarios and backed by a 30-day warranty, so nothing important slips through under deadline pressure.

You own the system that runs your jobs

The code, the data and the integrations stay yours — no per-seat pricing that climbs each year, no lock-in — so the software that runs your business is yours to run, extend or move.

How we work

From walking a real job to software that fits how you build.

Understand how a job really runs first, design around the office-to-site flow, agree a clear plan, build and test it on real site conditions, then roll out and keep improving.

01

Walk a real job with you

We start with how a job actually runs from bid to handover — your estimating, the office-to-site flow, the tools and accounts you already use, and exactly where the data breaks — so nothing important is discovered late.

02

Design around the office-to-site flow

We design the connection between the field and the office first, and the accounting and supplier integrations up front, rather than building features and bolting the plumbing on at the end where these projects usually fail.

03

Agree a clear, prioritised plan

You get a plain-English scope with defined outcomes and a fixed price, so you know what will be built, in what order and what it will cost before any development starts.

04

Build, test and prove it on a real job

We build in slices, each tested by our dedicated QA department against real site conditions — no signal, messy variations, awkward job costing — so your team sees working software early and the hard cases are caught before they hit the site.

05

Roll out on site, support and improve

We help you roll out carefully with the crew, support the system under a 30-day warranty and beyond, and keep it current as your jobs, trades, integrations and reporting needs change.

Pricing

Software that fits your jobs, without the enterprise price tag.

Senior engineers from around USD 25 per hour, the same capability Australian, US, Canadian and Middle-East firms charge a fortune for, at a fraction of the price. We scope the work clearly up front so you get a fixed, plain-English quote, and every engagement leaves you owning your code, data and integrations outright — with no per-seat pricing climbing every year.

Best for a defined system

Fixed-scope build

For a clearly scoped platform, estimating tool, field app or job-costing system, we agree the scope, the outcomes and the price up front, then build and prove it against how your jobs really run.

Best for ongoing work

Dedicated development team

A senior team that understands construction and your systems, working as an extension of yours, that you can scale up or down as jobs, seasons and priorities shift.

Best when a tool almost fits

Extend or integrate what you have

Where a packaged platform nearly works, we build the custom pieces and the accounting, payroll or supplier integrations that make it match how your business actually operates.

Every project is delivered by senior specialists under one accountable team, tested by a dedicated QA department against real site conditions, backed by a 30-day warranty — and you keep the code, data and integrations with no lock-in. Not sure whether to build, extend or buy? We will give you an honest recommendation on a free scoping call and send you a free, no-obligation written estimate with a clear scope.

Common questions

Construction software development, answered.

What is construction software development?

Construction software development is the practice of building custom software shaped around how a specific construction business actually runs — its estimating, its jobs, the flow between the office and the site, and the accounting, payroll and supplier systems it already uses — rather than forcing the business to fit a generic tool. It covers construction and project management platforms, estimating and takeoff tools, offline-first field and site apps, job costing, scheduling and subcontractor coordination, and safety, compliance and defect tracking.

The part that decides success is usually the connection between the field and the office: work, costs and problems happen on site in real time, and if that data does not reach the office cleanly, the business is always managing yesterday. Avaib has delivered software across more than 600 projects since 2004, including project, estimating, field and job-costing systems, so the operational reality of construction is understood before the build starts.

Why do off-the-shelf construction platforms fall short for so many firms?

Because the big platforms are built and priced for the general contractor on a large job. A builder, a subbie or a specialist trade ends up paying for modules they never open, on a per-seat or per-volume price that climbs every year, while the parts that matter for their business are missing or awkward. That is why so many firms buy a platform, use a fraction of it, and keep the rest of the work in spreadsheets.

The other common failure is shallow integration and a weak field app: the software does not really talk to the accounting package, and the crew on site abandons it because it adds a login and gives them nothing back. Custom software fixes both — it is built around what your business actually runs on, and around what the field will actually use.

Can you connect our software to QuickBooks, Xero or Sage?

Yes. Most of the pain in construction software comes from the office-to-site and the software-to-accounting gaps, so integration is where we put our senior people first. We build proper two-way links to QuickBooks, Xero or Sage, and to payroll and supplier systems, so estimates, costs, change orders and invoices move once and match on both sides.

This is exactly where off-the-shelf tools tend to fall down — one-way syncs that still leave change orders and subcontractor payments to be keyed in twice. We build the integration to hold up against how those systems really behave, so your job costing and your accounts stay in agreement.

Will the app work on site with no signal?

Yes. We build the field app offline-first, because a lot of construction happens where there is no coverage — basements, rural blocks, behind concrete and steel. The crew can record hours, photos, materials, variations and defects with no signal at all, and everything syncs the moment a bar of reception returns.

This matters more than it sounds. A field tool that spins and times out gets abandoned after two or three tries, and the crew goes back to paper. Building offline-first from the start is what keeps the data flowing and keeps the office out of the dark.

How does live job costing help me make more money?

Construction runs on single-digit margins, so the difference between a profitable job and a loss is often a leak you did not catch in time. When job costing lands weeks after the work, the profit is already gone. We tie labour, materials, subcontractors and change orders together so costs roll up as they happen.

That means you can see whether a job is tracking to budget while there is still time to act — reallocate a crew, chase a variation, fix a rate — instead of finding out at handover that a job lost money. Catching a leak in week two rather than at the end is where the return on the software usually comes from.

Should we build custom or use an off-the-shelf construction platform?

It depends on how much of your business a packaged product genuinely covers. For a large head contractor, an enterprise platform may fit well. For a builder, a subbie or a trade with a specific way of working, off-the-shelf tools rarely fit the estimating, the job costing and the office-to-site flow that make the business yours — which shows up as spreadsheets, double entry and a crew that ignores the app.

Where a packaged product almost fits, the smart move is often to extend and integrate it rather than replace it. Where the gap is too wide, custom software gives you a system that matches how you really run, without paying every year for features you never use. We help you decide honestly which route fits your business and your budget.

Can you handle safety, compliance and defect tracking?

Yes. SWMS and inductions, safety checklists, certifications, defect and snagging lists and defect-liability tracking can all live in the same system as the rest of the job, built for the trade doing the work rather than bolted onto a platform designed for the head contractor.

Because it is captured on site in the same app the crew already uses, compliance stops being a separate paperwork exercise and becomes part of the daily flow — which means the records are actually there when you need them for an audit, a claim or a handover.

Will we own the software you build?

Yes, completely. You own the code, the data and the integrations throughout, so the construction system you paid for, and the wiring that connects it to your accounts, payroll and suppliers, are yours to run, extend or move to another team whenever you choose.

Our work is backed by a 30-day warranty and ongoing support if you want it, but you are never locked in and there is no per-seat price climbing every year. The relationship continues because the software keeps earning its place on your jobs, not because leaving would cost you the system that runs your business.
