Project Cost Management for Construction

Project cost management software gives you a live view of what your projects are costing versus what you budgeted — purchase orders, invoices, subcontractor claims, timesheets, expenses, variations, all in one place. For NZ builders, the alternative is usually a mix of Xero, spreadsheets, and email, which means financial information is always delayed and often incomplete. Lentune brings every cost, committed and actual, into one dashboard so you can make decisions based on current numbers rather than last month's data.

Every cost enters the system at the point it's committed, whether that's a purchase order, a subcontractor agreement, or an approved variation. As invoices and expenses come in, they're matched against those commitments and your budget updates automatically. You can see where each project stands, by cost code, at any point in the month.

Yes. The Construction Contracts Act 2002 requires payers holding retention money to keep detailed ledger records. Retentions in Lentune are calculated automatically across head contracts and subcontracts, with release management and full audit trails built in — supporting the record-keeping the Act requires and removing the reliance on manual spreadsheets.

Lentune sits between your project and Xero. Every cost is validated, coded, and approved inside Lentune before it flows through to Xero. That means your Xero data is clean, accurate, and project-coded from the start, with no manual re-entry and no reconciliation headaches.

Yes. Lentune includes progress claim and subcontractor claim management, with payment schedules and retention tracking built in. Your claims go out accurately and on time, and you have a clear record of what's been certified and what's outstanding. All in line with CCA 2002 requirements.

Hundreds of NZ construction companies use Lentune, including Cook Brothers Construction, a nationwide NZ builder with offices throughout the country. LT McGuinness, one of NZ's leading commercial construction companies, also uses Lentune for invoice automation.

Spreadsheets are static. They show you where costs were, not where they are. They don't capture committed costs from purchase orders or subcontractor agreements, and they don't update when invoices are approved. Lentune gives you a live view of every project, with workflows that capture costs at the source. Customers who switch report up to 80% reduction in admin time — and more importantly, they catch margin problems before they compound.

Lentune implementation typically takes up to eight weeks, with many NZ construction businesses going live sooner. The process starts with a discovery call to understand your workflows, approval structure, and Xero setup. From there, your dedicated implementation specialist works alongside your team all the way through to go-live — with hands-on support the whole way.
