Guide · Open Job Value
Your real ceiling isn’t how many homes you can build.
It’s your balance sheet.
To build residential work for an owner, you generally need home-warranty cover, and the insurer sets how much work you’re allowed to have under construction at once. That limit is read off your financials, not your capability. Plenty of capable builders are capped well below what they can actually deliver.

01 / The basics
In plain English
To carry out residential building work above the prescribed thresholds for an owner in Australia, a licensed builder generally has to take out home-warranty insurance before contracting the job: the Home Building Compensation Fund (HBCF) in NSW, Domestic Building Insurance (DBI) in Victoria, the Home Warranty Scheme in Queensland, and similar schemes elsewhere. The thresholds and exact mechanics vary by state, but the function is the same: the cover protects the homeowner if their builder dies, disappears or becomes insolvent during the build or the defects period afterwards.
Because the insurer is taking on real risk, builders are assessed for financial capacity, by automated scorecard for smaller profiles, by manual underwriting for larger ones. Two numbers come out of that assessment:
- ANTA (Adjusted Net Tangible Assets). The genuine equity in the business after intangibles and certain related-party balances are stripped out and the rest is weighted toward a fire-sale recovery position. In plain terms: what the business is really worth if it had to be wound up.
- OJV (Open Job Value). The maximum total contract value of work you’re permitted to have under construction at any one time. Stronger ANTA earns a higher OJV; thinner ANTA holds the limit down.
Why this is the real ceiling
Land release, planning reform and buyer demand all matter, but they feed work into a capacity envelope that’s set somewhere else entirely. For a single business, the amount you can have on the go at once is bounded by your OJV. To grow, you don’t just win more work. You have to lift the limit. And the limit is a financial measure, drawn from financial statements interpreted by people who think like financial professionals.
That’s the gap. Builders are licensed and assessed on construction capability, rightly so. But the limit they’re then granted is read off the books. Many genuinely capable builders find themselves capped well below their operational ability, not because they can’t deliver homes, but because no one ever taught them to build the balance sheet the system rewards alongside the houses.
02 / The reality
Where builders get stuck
Capped on financials, not capability
You can run more jobs than your OJV allows. The constraint isn’t your team or your trades. It’s the equity an underwriter can see on the books.
Books that lag the business
Financial statements reconstructed months after the fact understate a business that’s actually performing. An underwriter prices what they can see, not what you know is true.
The write-off trap
The instant asset write-off brings forward deductions, which lowers reported profit, retained earnings and equity, and therefore ANTA. The tax tool that helps cash can quietly tighten your OJV.
Margin lost to late cost data
Overruns found at close-out instead of at 2% eat into profit. Lower profit means lower retained earnings, which means a thinner equity base for next year’s assessment.
WIP guessed, not measured
Over-billing flattered as profit, or under-billing left invisible, distorts the financial position the assessment relies on, in either direction.
No line of sight to the limit
If you don’t track total contract value under construction, you only discover where you sit against your OJV when you bump into it mid-tender.
03 / The fix
A workflow that holds up
- 01
Keep the books current
Process supplier invoices and claims as they happen so your financials reflect the real business, not a year-end reconstruction.
- 02
Run accurate WIP
Know your true over- and under-billing position across every job so reported profit is real, not a timing illusion.
- 03
Protect retained earnings
Understand how deductions, write-offs and timing decisions hit equity before year end, because equity is what ANTA is built from.
- 04
Catch overruns early
Track budget vs committed vs actual live, so margin survives the job and flows through to the balance sheet.
- 05
Present clean, timely financials
Give your accountant (and any underwriter) statements they can rely on, structured so the business’s real strength is legible.
- 06
Track where you sit against your OJV
Watch total contract value under construction so you manage the ceiling on purpose, instead of finding it by accident.
04 / The tooling
How software helps
OJV is, in the end, a reflection of the financial strength of the business, and that strength is both built and demonstrated through the books. Accurate cost, real WIP, margin that survives the job, and timely financial statements are what turn genuine operational capability into equity an assessor can actually see.
Software can’t underwrite you, and it can’t set your limit. Your insurer does that. What it can do is keep the inputs honest and current, so a capable business stops looking weaker on paper than it really is. When cost is live, claims are tracked by stage, and WIP reflects reality, the numbers your accountant prepares and an underwriter reads describe the business as it actually is.
05 / In practice
Where VIABUILD fits
VIABUILD keeps the financial picture honest, so your business presents its real strength.
VIABUILD doesn’t set or lift your OJV. That sits with your insurer and underwriter. What it does is keep the numbers those decisions rely on accurate and current: AI accounts payable processes supplier invoices as they arrive so actual cost is live; real-time cost tracking shows budget vs committed vs actual with variance alerts that fire at 2%, not at close-out; progress claims are tracked by stage; and native two-way Xero sync keeps the books clean without double entry.
The result is a business whose financial position is visible and defensible, to you, to your accountant, and to anyone assessing your capacity. You can’t shortcut the equity, but you can stop losing it to stale data and surprises.

06 / FAQ
Common questions.
Open Job Value is the maximum total contract value of residential work a licensed builder is permitted to have under construction at any one time. It comes out of the financial assessment home-warranty insurers run (HBCF in NSW, DBI in Victoria, the Home Warranty Scheme in Queensland and similar schemes elsewhere) and effectively caps how much work you can have on the go at once.
ANTA (Adjusted Net Tangible Assets) is the genuine equity in your business after intangibles and certain related-party balances are removed and the rest is weighted toward a fire-sale recovery position. It’s the core measure underwriters use to gauge financial capacity: stronger ANTA generally earns a higher OJV, while thinner ANTA holds the limit down.
Because licensing assesses construction capability, but OJV is a financial measure read off your financial statements. A builder can be perfectly able to deliver more homes yet be limited because the equity on the books doesn’t reflect it, often because no one taught them to manage and present the balance sheet the scheme rewards alongside running the jobs.
It can. Bringing forward deductions lowers reported profit, which lowers retained earnings and therefore equity, and ANTA is built from equity. So a tax tool that improves short-term cash can simultaneously reduce the financial capacity an underwriter will support. It’s worth modelling the OJV impact with your accountant before year end, not after. This is general information, not tax advice.
No. Your insurer and underwriter set your limit. What software can do is keep your cost, claims, WIP and financials accurate and current, so your business presents its true financial strength instead of looking weaker on paper because the data was stale or the margin leaked away unnoticed.
