We build the software
we wished builders had.
VIABUILD is construction management for Australian builders, built in Sydney to remove the back-office admin that eats your evenings, and to show you where your jobs really stand while you can still act.
01 / Why we built it
The problem we kept seeing
Builders are some of the busiest people in any trade, on the tools or on site all day, then doing the admin at night. Invoices keyed into Xero after dinner. Margins discovered at close-out, when it’s too late to fix them. Quotes that take so long the lead goes cold. Safety in a second app with a second bill.
None of that is the building. It’s the back office wrapped around the building, and most software made it heavier, not lighter. So we set out to build a platform that takes the admin off the builder: a dedicated AI accounts inbox instead of manual data entry, live cost tracking instead of a month-end spreadsheet, and a site app supervisors will actually use.
VIABUILD keeps accounting in Xero where it belongs, and focuses on the construction workflow (estimate, win, build, claim, know) on one platform, at one price.
02 / What we believe
How we think about builder software
Built in Australia
Designed in Sydney for Australian builders: GST, BAS, ABN matching, Xero. Built for how building works here, not a US product with the currency changed.
Tested at real volume
We test at builder volume (hundreds of invoices a month, dozens of active jobs, multiple estimators quoting at once), not in tidy demo conditions.
Fast or it’s a bug
Keyboard-first, instant navigation, no loading spinners. If the software is slow, we treat it as a defect, not a fact of life.
One platform, one price
Estimating, scheduling, AP, cost tracking, claims, selections, safety and ViaSite are all included. No à la carte modules or AI surcharges.
Earn it monthly
Month-to-month billing with no lock-in is available. We’d rather keep you because the software is good than because a contract traps you.
Accounting stays in Xero
We don’t try to be your accounting system. Construction management here, accounting in Xero, synced, so your bookkeeper keeps their tools.
03 / Where we are
Built in Sydney, for Australia
VIABUILD is built in Sydney. That’s not a marketing line. It’s why the product handles GST and BAS properly, matches ABNs, and integrates natively with Xero with tracking categories. The workflow is shaped around how Australian residential and mid-market builders actually run jobs, from progress claims to the way subbies send invoices.
We’re deliberate about what we claim. You won’t find fabricated awards, invented customer counts or made-up ratings on this site. Where we describe a result, it’s tied to how the product works, and we’d rather under-claim and let the software prove itself on your own jobs.
04 / Who's behind it
The builder behind VIABUILD
Brad Caldon is the founder of VIABUILD and a builder and property developer with nearly two decades across residential construction and development. He holds a NSW Home Builder Licence, is a Registered Building Practitioner across Class 1 to Class 9 buildings, and holds a Bachelor of Construction Management (Building) (Honours) from the University of Newcastle.
VIABUILD’s guides on construction finance and delivery are written from that experience, grounded in live projects and real balance sheets rather than theory.
