Xero closes your month. Your real job costs land three weeks late
Custom accounting software, or more often a custom layer on top of Xero or QuickBooks, runs AUD $60k to $150k over 3 to 6 months in Perth. You build custom when your accounting depends on job costs captured at remote sites, and the data arrives weeks after the work, so QuickBooks and Xero close a month that isn't actually true yet.
QuickBooks, Xero and FreshBooks are strong general-ledger tools, but they assume costs arrive promptly and tidily. In Perth's resources and construction world they don't. Labour, plant hire and consumables get racked up at a site hundreds of kilometres inland and sit on a paper ticket until the crew flies home and someone keys them in. So your accounting software is always closing a period before half the costs have landed, and your job profitability is a guess until the dust settles weeks later.
You rarely need to replace Xero. You need to fix the on-ramp: get real job costs into the ledger when the work happens, not when the paperwork catches up. Without that, every progress claim, every WIP report and every margin number is built on stale data.
The case for owning your accounting
You build a custom layer when the ledger is fine but the on-ramp is broken. Capture job costs at site, offline, in real time, then push clean data into Xero or QuickBooks so the period you close reflects the work that actually happened. Add the job-costing depth standard accounting tools lack, multi-cost-centre jobs, phased shutdown billing, retention, and your margin numbers stop being a three-week-late guess.

Delivery, week by week
Exactly what you get
You get the cost on-ramp Xero and QuickBooks are missing: offline job-cost capture at remote sites that syncs when signal returns, proper job-costing depth for multi-phase shutdowns, progress-claim and retention handling, and a clean sync into your existing ledger. The period you close reflects the work that actually happened, and your margin and WIP reporting is real-time, not a three-week-late guess.
How to choose a developer in Perth
Hire a team that respects the ledger you already run and fixes the on-ramp instead. Ask how site costs reach Xero before the crew flies home. Ask them to cost a multi-phase shutdown on a whiteboard. Insist an accountant validates the chart-of-accounts mapping. If they want to rip out Xero on day one, they're solving the wrong problem. The right partner keeps your ledger and makes the numbers true on time.
- Job costs hit the ledger when the work happens, not weeks later
- Periods close on real data, so margin and WIP are trustworthy
- Progress claims and retention handled with proper job-costing depth
- Plant, labour and consumables captured against the right job at site
- Keeps Xero or QuickBooks as the ledger while fixing the cost on-ramp
- You still run and pay for Xero or QuickBooks underneath
- Accounting integrations break when vendor APIs change, and you own the fix
- Getting the cost logic wrong produces fast, confident, wrong numbers
- If your costs already land promptly, there's little to gain here
- !They offer to replace Xero wholesale. Ask why a capture layer won't fix the lag first
- !No offline cost capture. Ask how site costs reach the ledger before the crew flies home
- !No job-costing depth. Ask how they cost a multi-phase shutdown
- !No accountant involved. Ask who validates the chart-of-accounts mapping
- !They can't show a progress-claim build. Ask for one they've shipped for a WA contractor

Frequently asked questions
Do we need to replace Xero or QuickBooks?
Almost never. The ledger is usually fine; the problem is job costs arriving weeks late. A custom capture layer that feeds Xero or QuickBooks fixes the lag without a disruptive replacement.
How do site costs get in on time?
Crews capture labour, plant and consumables against the job at site, offline, and it syncs to the ledger when signal returns, so the costs land when the work happens, not when the paperwork catches up.
Can it handle progress claims?
Yes. Proper job-costing depth, phased shutdown billing, retention and progress claims for WA construction terms is exactly what standard accounting tools lack and a custom layer adds.
What does it cost?
AUD $60k to $150k depending on depth. A plant and consumables allocation module alone runs $45k to $75k.
