Xero closes a cafe's books and chokes on a builder's progress claim
Custom accounting software for a Newcastle contractor runs $55,000 to $150,000 and ships in 4 to 7 months. You build instead of QuickBooks or Xero when your finances are project-based: progress claims under the Security of Payment Act, retentions held across a job, and work-in-progress that a cafe-shaped ledger cannot represent. Xero is excellent for simple businesses and wrong for a builder running staged construction accounts.
Xero runs beautifully for a straightforward business, which is exactly why every Hunter accountant recommends it, and exactly why it fights a builder. Construction money does not move in tidy invoices, it moves in progress claims and payment schedules under the Security of Payment Act, with retention held back and released later, variations mid-job, and work-in-progress that has to be recognised before a cent is invoiced. Xero has no native model for any of that.
So your project accounts live in spreadsheets that shadow Xero: a claim schedule, a retention register, a WIP calculation someone updates monthly. The general ledger is technically correct and operationally useless, because the real financial position of each Hunter job is somewhere else, and reconciling the two is a monthly ritual nobody enjoys.
Where the off-the-shelf tools fall short
- Xero and QuickBooks have no native progress claim or payment schedule under the Security of Payment Act
- Retention held and released across a job is tracked in a spreadsheet beside the ledger
- Work-in-progress recognition on Hunter construction jobs is calculated off-system
- Variations mid-job are hard to represent, so job profitability is never quite current
Custom accounting: what Newcastle teams actually get
Custom accounting software models construction money as it actually flows: progress claims and payment schedules timed to the Security of Payment Act, retention tracked and released automatically, variations captured, and work-in-progress recognised per job. It keeps GST, BAS, and Peppol e-invoicing correct while giving you a live financial position per Hunter project. The shadow spreadsheets disappear because the ledger finally understands your business.
- Your money moves in progress claims and retentions, not simple invoices
- Project accounts live in spreadsheets shadowing Xero
- You cannot see live per-job profitability
- Security of Payment Act timing matters to your cash flow
- Your business is simple and invoice-based
- Xero or QuickBooks already models your finances well
- You do not run staged, retained, or WIP-based work
- Your volume does not justify a custom build
- Progress claims and payment schedules built to Security of Payment Act timing
- Retention tracked and released automatically across each job
- Work-in-progress recognised per project, so job profitability is current
- GST, BAS, and Peppol e-invoicing kept correct alongside project accounting
- One live financial position per Hunter job instead of a ledger plus spreadsheets
- Construction accounting logic is complex and costs more than a Xero subscription
- You need finance input to validate claim, retention, and WIP rules
- Integrations to payroll and project systems add scope
- For a simple, non-project business, Xero is the right answer and building is waste

Newcastle accounting: the full scope
The engagements Newcastle teams bring us most often: expense management, custom accounting software, QuickBooks integration, Xero integration, invoicing software, bookkeeping software and financial reporting.
The honest cost picture for Newcastle
| Project scope | Typical cost | Timeline |
|---|---|---|
| Project accounting core with claims | $55,000 to $85,000 | 4 to 5 months |
| Accounting with retention and WIP | $85,000 to $120,000 | 5 to 6 months |
| Full build with job costing integrations | $120,000 to $150,000 | 6 to 7 months |
Timeline: what happens, and when
Exactly what you get
You get accounting software that speaks construction: progress claims and retentions timed to the Security of Payment Act, WIP recognised per job, and GST and BAS kept correct throughout. It pulls costs from a project system, labour from an HR (Human Resources) and payroll build, and materials from inventory for full job costing. You own the code and your financial data.
How to choose a developer in Newcastle
Choose a team that has built Australian construction accounting, and ask them to model a progress claim with retention under the Security of Payment Act before you sign. Confirm they handle work-in-progress recognition and keep GST, BAS, and Peppol e-invoicing correct, because a builder's ledger has to satisfy both the ATO and the payment schedule. A partner who understands Hunter construction cash flow will design for claims and retentions as the core, not as add-ons to a generic ledger.
- !They have not built progress claims. Ask for a Security of Payment Act claim example they shipped
- !They treat retention as a note. Ask how hold and release is tracked automatically
- !They skip WIP. Ask how per-job profitability is recognised before invoicing
- !They ignore GST and BAS. Ask how ATO compliance sits alongside project accounting
- !They keep the ledger proprietary. Ask whether you own the financial data and code

Frequently asked questions
What does custom accounting software cost for a Newcastle builder?
Most builds run $55,000 to $150,000. A project accounting core with progress claims starts near $55,000, while retention, WIP, and full job-costing integrations run higher. Expect 4 to 7 months, with claim and retention logic driving the timeline.
Why can't we just use Xero for our construction accounts?
Xero is built for simple, invoice-based businesses and has no native progress claim, retention, or WIP model, which is the heart of construction finance. So your real per-job position ends up in spreadsheets shadowing Xero. A custom system models claims, retentions, and WIP directly.
Does it handle Security of Payment Act progress claims?
Yes. The build times progress claims and payment schedules to the Security of Payment Act, which governs how and when you can claim and be paid in NSW. Getting that timing right protects your cash flow and your rights, which a generic invoice cannot do.
How is retention tracked and released?
Through a retention register that holds the agreed percentage per claim and releases it automatically on the agreed dates or milestones. That removes the spreadsheet where retention usually lives and the risk of forgetting to claim it back. It is standard scope for construction accounting.
Can it show live profitability per Hunter job?
Yes. By recognising work-in-progress and pulling costs from your project, payroll, and inventory systems, it gives current per-job profitability rather than a figure you calculate monthly. That visibility is often the main reason builders move off Xero plus spreadsheets.
Does it keep GST, BAS, and e-invoicing compliant?
Yes. GST tagging, BAS-ready reporting, and Peppol e-invoicing are built in and sit alongside the project accounting, so you satisfy the ATO and the payment schedule at once. Compliance is core scope, not an afterthought.
Will it integrate with our project and payroll systems?
Yes. We connect project costs and payroll labour so job costing is complete and accurate, rather than assembled from exports. That end-to-end link is what makes per-job profitability trustworthy.
How long until it runs our books?
Plan on 4 to 7 months, and we parallel-run against your current process until the numbers reconcile before you rely on it. Accounting is unforgiving, so we validate claims, retention, WIP, and GST against real jobs before cutover.
Do we own the accounting code and data?
You do. You receive the source code and the financial database, so your ledger and project accounts are yours to keep. Confirm this in writing, since financial data is among the most costly things to be locked out of.
Can custom software connect to the tools we already use, like QuickBooks, Stripe, and Google Workspace?

Who can build custom accounting software for a business in Newcastle?
Digital Heroes builds custom accounting software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, so an operator in Newcastle gets an assigned senior team rather than a local account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other accounting software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
