Project Cost Management for Construction

Construction project cost management software captures every cost on a project — purchase orders, invoices, subcontractor claims, timesheets, expenses, variations — and tracks them against your budget in real time. The goal is to give you an accurate picture of where your project stands financially at any point, not just at month end. Lentune is built specifically for this, with workflows designed around how construction businesses actually operate.

The moment a purchase order is raised in Lentune, that committed cost hits your project budget immediately. As invoices are processed, deliveries confirmed, and claims approved, the financials update automatically. You're not waiting for a manual reconciliation to find out your true position. For Australian commercial builders managing large subcontractor workforces across multiple sites, that live visibility is the difference between catching a margin problem early and finding out about it at month end.

Yes. Retentions are withheld automatically on both head contracts and subcontracts, tracked through the project lifecycle, and released with a full audit trail. This feature directly supports the documentation and process discipline that Security of Payment obligations require across Australian states.

Spreadsheets require manual data entry, are prone to errors, don't update in real time, and give you no automated approval workflows. The bigger your business and the more projects you run, the more the spreadsheet approach breaks down. Customers who move to Lentune report up to 80% reduction in admin time on average. More importantly, they get accurate committed cost visibility before problems compound — not at month-end when it's too late.

Committed costs are costs your business has agreed to pay but hasn't paid yet, including purchase orders raised with suppliers, subcontract agreements signed, approved variations. Most accounting systems only show you actual spend, which means you can't see your true financial position until costs are invoiced and processed. Lentune captures committed costs the moment they're created and tracks them against your budget, so you always know your real exposure.

Lentune includes subcontractor claims functionality for creating subcontracts, reviewing and approving subcontractor progress claims, generating payment schedules, and tracking retentions. Claims can be checked against the relevant subcontract, reviewed through Lentune's claim workflow, and approved by the appropriate team members. Retentions can be applied based on the subcontract's retention policy, with retention balances tracked and reported across both head contracts and subcontracts. Retention releases are managed through the relevant subcontract or head contract process and recorded against the contract.
