Receipts disappear between the site and the office
Construction project managers deal with a constant stream of small purchases: hardware store runs, fuel, safety equipment, site supplies, subcontractor materials. Each purchase generates a receipt. Each receipt needs to make it from the job site to the finance team.
Most do not make it.
Receipts get left in ute glove boxes, crumpled in high-vis pockets, or thrown away with the packaging. By the time the finance team asks for them, the purchase was three weeks ago and nobody remembers the details.
The result is incomplete records, lost GST credits, and a month-end reconciliation process that the finance team dreads.
Why shared cards and petty cash fail on construction sites
Shared cards hide who spent what. When three site managers share one company card, the finance team sees transactions but cannot attribute them to specific people, projects, or cost centres without manual investigation. This lack of attribution makes it impossible to track project-level profitability accurately.
Petty cash is uncontrollable. Cash floats distributed to sites disappear into a black hole of undocumented spending. The finance team reconciles what they can and writes off the rest. For companies running five or more active sites, the cumulative write-offs can be substantial, and the lack of documentation creates problems at BAS time when GST credits cannot be claimed without valid receipts.
Fuel cards only cover fuel. Many construction companies use dedicated fuel cards, but site managers still need to buy hardware, safety gear, and supplies. That spending falls back to petty cash or reimbursements.
Reimbursements slow everything down. Site managers who pay out of pocket wait weeks for reimbursement. Some stop submitting claims entirely, which means the company loses visibility over what was spent. The finance team ends up with incomplete records, and the site manager ends up absorbing costs that should be on the company’s books.
India Robertson, Office Manager at HSC Facility Services, managed this across 40 employees:
“Budgetly has saved us huge amounts of time and money.”

HSC saves 10 hours per week, a 1.5-day reduction in admin workload.
What per-site expense management looks like
The replacement is per-site budgets with individual cards for each project manager or site supervisor:
Each site gets its own budget. A residential build has a different expense profile than a commercial fit-out. Each site budget reflects its scope and timeline, with spending limits that prevent overruns.
Individual cards for site managers. Each person who makes purchases gets their own Visa debit card linked to their site’s budget. No more shared cards, no more “who spent $340 at Bunnings?”
Receipt capture at the point of purchase. The site manager taps the card, photographs the receipt on their phone, and the transaction is documented. The finance team sees it in real time.
Category controls. Cards can be restricted to approved merchant categories (hardware, fuel, safety equipment) and blocked for categories that are not relevant to site operations. This automated control replaces the manual approval step that slows down purchasing on active sites, while still ensuring that company funds are spent on legitimate project expenses.
Site Sentry Australia consolidated three separate admin processes into one after making the switch, cutting admin time significantly.
Tracking costs across multiple projects
For construction companies running multiple projects simultaneously, the ability to track expenses by project is critical for profitability analysis.
When each project has its own budget and cards, every transaction is automatically attributed to the right project. The finance team can see:
- Total spend per project in real time
- Spend by category (materials, fuel, equipment, subcontractors)
- Budget remaining versus budget allocated
- Which projects are trending over budget before it is too late to act
This data feeds directly into project profitability calculations. Instead of estimating site expenses at month-end, the project manager knows the exact position at any point. For companies quoting on new work, having accurate historical expense data from completed projects means more precise estimates and better margins.
The visibility also helps with cash flow planning. When the finance team can see committed spending across all active projects in real time, they can forecast cash requirements more accurately. This is particularly important for construction companies that manage progress payments and need to ensure they have sufficient working capital to cover site expenses between payment milestones.
Hunt & Dixon Surveys saves six hours per week on expense administration. Easy Insulation saves up to six hours per week. Bennett and Bennett erased spreadsheets and saved a full day of admin each month. Site Sentry Australia consolidated three separate processes into one, cutting the administrative overhead that was slowing down their operations team.
GST recovery on site purchases
Construction companies make hundreds of small purchases per month across multiple sites. Each purchase under $82.50 needs a receipt showing the supplier’s ABN to claim the GST credit. Each purchase above $82.50 needs a full tax invoice.
When receipts go missing from site purchases, the GST credits are lost. For a company spending $100,000 per month across sites, even a 5% receipt loss rate means $450 per month in unclaimed GST. Over a financial year, that is more than $5,000 in credits that the business is entitled to but cannot claim.
Digital receipt capture at the point of purchase eliminates this leakage. Every receipt is stored, every GST amount is extracted, and BAS preparation becomes a data export. The finance team no longer needs to chase site managers for missing documentation before each BAS lodgement.
Tim Huett, CFO at Earth Markets, described the compliance confidence this creates:
“I’m carrying zero risk in terms of record keeping, compliance and document management for ATO/ASIC.”

Earth Markets saves 30 hours per month across their stores and 20 hours per month at head office. That level of time recovery is typical for construction and trades businesses that move from fragmented tracking to a single system.
The data also feeds into budgeting for future projects. When the finance team has accurate, categorised expense data from completed projects, they can quote more accurately on new work. Instead of estimating site expenses based on gut feel, they have real numbers from comparable projects.
