Xero balances your Brisbane books to the cent but can't show a job's true margin until retention clears a year later
Custom accounting software for a Brisbane construction or project-based firm runs $50,000 to $150,000 over 5 to 9 months. Xero, QuickBooks, and FreshBooks are excellent general ledgers, but they think in invoices and months, not progress claims, retention, and work-in-progress. For a builder, that means the GL balances while job profitability stays invisible. Accounting software built in Brisbane adds the construction money logic, claims, retention, and WIP, on top of compliant Australian bookkeeping.
Xero does your BAS, your payroll feeds in, and the books balance to the cent. It still can't answer the question that matters: did the Northshore job actually make money. A progress claim isn't a normal invoice, retention held at 5% won't be released until a year after practical completion, and work-in-progress, cost incurred but not yet claimed, has no natural home. So the quantity surveyor reconciles all of it in a spreadsheet, and the real financial position of each job lives outside the accounting system.
That's the gap between a general ledger and construction accounting. Xero and QuickBooks model a business that sends invoices and collects them, with simple accrual. A Brisbane builder runs on progress claims against a schedule, retention held and released over a year, variations that change contract value mid-stream, and WIP that has to be recognised correctly. When the accounting software can't hold those, your compliance is fine but your management accounts are a spreadsheet, and that spreadsheet is where the errors and the underclaimed money hide.
The fix: accounting built for Brisbane, not rented
You build when construction money logic, claims, retention, and WIP, is the part of accounting that matters and your GL can't hold it. Custom accounting software for a Brisbane builder adds progress-claim schedules, retention tracking with release dates, WIP recognition, and variation handling on top of compliant Australian bookkeeping, so management accounts and the books are the same numbers. You stop running the real financials in a spreadsheet. It shares one ledger with your ERP (Enterprise Resource Planning) software, project management software, and business intelligence dashboards, so job margin is live, not reconstructed monthly.

How long it takes, phase by phase
Exactly what you get
Accounting that speaks construction on top of compliant Australian books. Progress claims are tracked against each contract schedule with claimed, certified, and outstanding amounts; retention is held and released per head contract with dates surfaced; work-in-progress is recognised so job margin stays true through the job, not just at close; and variations flow to contract value automatically, retiring the QS's reconciliation spreadsheet. BAS, GST, STP, and super stay exact, so management and statutory accounts are the same numbers. It shares one ledger with your ERP software, project management software, and business intelligence dashboards.
How to choose a developer in Brisbane
Hire a team that understands construction accounting, not just bookkeeping software. Ask them to explain WIP recognition, retention release, and how a variation flows to contract value and margin, in plain terms, and watch whether they actually know it. They must keep Australian compliance exact, BAS, GST, STP, so probe how they test that. They should be honest about migration of historical ledgers. Brisbane builders value straight numbers, so favour the developer who talks fluently about claims and retention over the one who treats it as a regular accounting app with a few extra fields.
- Progress claims tracked against the schedule in the books, so claiming and bookkeeping are one system, not two
- Retention held and released with dates, so the cash you're owed a year out stays visible and gets chased
- Work-in-progress recognised correctly, so job margin is true through the job, not just at close
- Variations flowing to contract value automatically, so the QS stops reconciling reality in a side spreadsheet
- Management accounts and statutory books that match, so the board sees the same truth as the BAS
- Construction accounting is genuinely specialised, so the build needs people who understand WIP and retention, not just coders
- You must keep Australian compliance, BAS, GST, STP, exactly right, which raises the bar on testing
- It's a 5 to 9 month project, more than configuring Xero, and competes with other priorities for budget
- If you replace rather than extend Xero, migration of historical ledgers is careful, slow work
- !They don't know what WIP recognition means in construction (ask: how do you recognise cost incurred but not yet claimed?)
- !They treat a progress claim as a normal invoice (ask: how do claims against a schedule differ from invoices here?)
- !They ignore retention (ask: how do you track held and released retention with dates over a year?)
- !They hand-wave BAS and STP (ask: how do you keep Australian compliance exact while adding construction logic?)
- !No migration plan for historical ledgers (ask: how do we move years of books without losing the audit trail?)

Frequently asked questions
Why can't Xero tell me if a job made money?
Because Xero is a general ledger built around invoices and months, not construction money logic. A progress claim isn't a normal invoice, retention sits unreleased for a year, and work-in-progress, cost incurred but not yet claimed, has no natural home. So the books balance while job margin lives in a quantity surveyor's spreadsheet. Custom accounting software adds claims, retention, and WIP so the system can actually answer whether the job was profitable.
What is WIP recognition and why does it matter?
Work-in-progress recognition reflects cost you've incurred on a job but haven't yet claimed for, so your accounts show the job's true position rather than understating it. Without it, margin looks wrong until you close the job, by which point a loss-making contract has run too long. For a Brisbane builder running long jobs, correct WIP is what makes management accounts trustworthy mid-project.
How much does custom accounting software cost in Brisbane?
Between $50,000 and $150,000 over 5 to 9 months. A construction accounting layer adding claims, retention, and WIP sits at the lower end. A full system with compliance and cash-flow forecasting sits at the top. Adding a claims and WIP layer over your existing Xero or MYOB, rather than replacing it, runs $40,000 to $75,000 and is often the lower-risk path.
Can we keep Xero and add the construction logic?
Yes, and it's usually the smart move. Xero handles compliant bookkeeping, BAS, and payroll well, so a custom layer can add progress claims, retention tracking, WIP, and variations on top, feeding the GL. That keeps cost down at $40,000 to $75,000 and avoids replacing a working, compliant ledger. Confirm during discovery that Xero can accept the journals cleanly so statutory and management accounts stay aligned.
Does custom accounting software stay compliant with Australian rules?
It has to, and that's a core part of the build. BAS, GST, Single Touch Payroll, and superannuation reporting must be exactly right, which is why you want a developer who treats compliance as non-negotiable and tests it hard. The construction logic, claims, retention, WIP, sits on top of that compliant base. Done properly, you get specialised job financials and clean statutory reporting from one system.
