Guide · Xero, day to day
How construction software works with Xero,
on a live job.
Construction software runs the job. Xero stays the ledger. This guide is the daily loop: connect once, map tracking categories, then push approved bills and claims across so nobody types the same number twice.

01 / The basics
In plain English
Most Australian residential builders already keep the books in Xero. After you have chosen construction software, the useful question is not “does it integrate”. It is what happens on a Tuesday: a supplier invoice arrives, a stage is reached, the bookkeeper opens Xero, and someone still has to make the two systems tell the same story.
The arrangement that holds is ordinary. Xero remains the accounting system. Bank feeds, BAS, payroll, the chart of accounts and the reports your accountant lives in stay there. Construction software sits beside it and holds what a general ledger was never shaped to hold: a job budget, purchase orders that commit cost before the invoice arrives, and progress claims against contract stages.
The join is the integration. Mapped well, a bill approved in the construction system lands in Xero as an authorised bill, already coded to the job through tracking categories. An approved progress claim, including approved variations, lands as a Xero invoice. Contacts stay aligned. The bookkeeper stops re-keying and starts checking exceptions.
The mapping is built once and inherited after that
Tracking categories are how Xero reports cost and revenue against each job. The construction system has to apply them when a bill or a claim crosses, or the ledger shows a lump and the job view shows a story your accountant cannot reconcile. That mapping is a setup job, not a daily one. Mapped loosely, you get books that balance and job numbers nobody trusts. If you are still choosing a product, construction software for Xero compares what each platform actually syncs. This page is what you do after that choice.
02 / The reality
Where builders get stuck
Connected, then typed in twice anyway
A common first-month habit is to keep keying invoices into Xero “just in case”. That habit is what keeps the double entry alive after the connection is already there.
Tracking categories that do not match the jobs
If the category list is leftover from last year’s chart, or one category covers every job, the ledger balances and the job reports are fiction.
Bills crossing without a job on them
An authorised bill in Xero with no tracking category is still a bookkeeping entry. It is not job cost. Someone will code it again at month end.
Claims typed into Xero separately
A connector that only handles cost leaves the revenue side being re-keyed. The claim the client approved and the invoice in Xero then drift apart.
Edits on the ledger side, unnoticed
Someone fixes a tax code or a contact in Xero and the construction system never sees it. The next sync either overwrites the fix or ignores it. Either way, the two copies diverge.
Month-end as a standing reconciliation
If the two systems only agree when someone sits down with both screens, the integration is an export, not a daily loop. The admin shift just moved to the last Friday.
03 / The fix
A workflow that holds up
- 01
Authorise the Xero organisation
Connect the construction system to the Xero organisation that already holds the books. Xero lets you work in a demo organisation first, which is a better place to see what a connection creates than a live ledger.
- 02
Line up tracking categories with jobs
Map each live job to the Xero tracking category you will report on. Do this against how you actually look at jobs, not against whatever list already exists in either system.
- 03
Raise purchase orders against the job budget
Commit cost in the construction system before the invoice arrives, so there is something to match and a job already on the spend.
- 04
Approve matched supplier bills in the construction system
Capture the invoice, match it to the purchase order, code it to the job, and approve it there. The approval is the gate. Nothing should reach Xero before a person has signed it off.
- 05
Let approved bills push to Xero as authorised bills
The bill lands in Xero already authorised, with tracking categories applied, so cost sits against the right job rather than as a lump. It is not re-typed.
- 06
Push approved progress claims as Xero invoices
When a stage is approved, the claim, including approved variations carried in it, becomes the Xero invoice. Revenue and cost then share the same job coding.
- 07
Leave the ledger work in Xero
The accountant keeps doing bank reconciliation, BAS and payroll in Xero. The construction system does not replace those jobs. It stops the same bill being typed twice before they start.
04 / The tooling
How software helps
Software earns its keep here by removing the re-typing, not by replacing the accountant. Capture and matching belong in the construction system, because that is where the purchase order and the job budget already live. A dedicated accounts payable inbox can extract the invoice, match it to the order and suggest the cost code, so approval is a check rather than data entry.
Once a person approves the bill, the integration’s job is narrow and specific: push it to Xero as an authorised bill with the tracking category already on it. The same pattern on the revenue side: an approved progress claim, including approved variations, becomes the Xero invoice. Contacts that should match stay aligned, so the supplier you approved in one system is the supplier your accountant pays in the other.
That is also why cost tracking stays current. The coded actuals that just landed in Xero are the same actuals sitting against budget and committed cost. If those two views disagree, the mapping or the approval gate is wrong, not the month. The object-by-object mechanics of VIABUILD’s own connection are on how the VIABUILD Xero sync works.
05 / In practice
Where VIABUILD fits
VIABUILD runs the build. Xero stays the ledger.
VIABUILD does not try to replace Xero. You authorise your Xero organisation once and line up tracking categories so cost and revenue land against the right jobs. From then on the construction side does the daily work: the estimate becomes the job budget, purchase orders commit cost, and the accounts inbox is where Oryn™ extracts supplier invoices, matches them to the purchase order and codes them to the job for you to approve.
Approved bills push to Xero as authorised bills with tracking categories applied. Approved progress claims, including approved variations, push as Xero invoices. Contacts stay aligned. Your accountant keeps working in Xero. VIABUILD does not run payroll, does not lodge BAS, and does not mark a bill paid. The accounting integration is Xero only. There is no MYOB connection today.
Start with 7 days free, then $555/month including GST. The Xero connection is part of the platform, not a separate connector. Xero itself is still billed by Xero.
- Xero stays the accounting system
- Authorise the organisation once
- Tracking categories lined up with jobs
- Approved bills push as authorised bills
- Approved claims, including variations, push as invoices
- Contacts kept aligned
- No MYOB integration today
06 / FAQ
Common questions.
No. Xero stays the accounting ledger. Construction software holds the job budget, the purchase orders and the claims. The integration keeps the two in step so a number entered once is not typed again. If a product wants to be both your construction system and your general ledger, that is a different purchase and it deserves your accountant in the room.
The job-to-tracking-category map. Xero uses tracking categories to report cost and revenue against each job. If that map is loose, every later bill and claim inherits the mess. Do the mapping against how you actually report on jobs, and try one real bill in a Xero demo organisation before a live job depends on it.
Approved supplier bills push as authorised bills with tracking categories applied. Approved progress claims, including approved variations carried in the claim, push as Xero invoices. Contacts stay aligned. The construction system does not mark bills paid, and an AI agent connected to VIABUILD cannot write to Xero. Bank reconciliation, BAS and payroll stay in Xero.
The ledger work that was always theirs: bank reconciliation, BAS, payroll, and the exceptions a sync cannot judge. What they should not still be doing is re-keying every supplier bill and every progress claim. If that is still happening after the connection is live, the mapping or the approval habit is wrong.
Not today. The accounting integration is built for Xero. If your ledger lives in MYOB, say so before you switch. We will tell you where that stands rather than sell you a roadmap. Other platforms that name MYOB are listed on the construction software for Xero comparison.
