Frequently asked questions
What is construction cost management software?
Construction cost management software captures and tracks every cost on a building project — invoices, purchase orders, timesheets, subcontractor claims, variations, and expenses — all reported against your budget in real time. For NZ builders, that means knowing where you stand on every job before problems get expensive, and having the data you need to make fast, accurate decisions. Lentune is designed specifically for this, and connects natively with Xero, which most NZ construction businesses already use for accounting.
What type of builders is Lentune designed for?
Lentune is built for New Zealand general contractors, commercial subcontractors, and residential cost-plus builders typically turning over between $5M and $100M. Cook Brothers is one example of a NZ construction company using Lentune to manage project costs at scale. It suits businesses that have grown beyond spreadsheets and need real-time project financial control — without the cost and complexity of a full ERP system.
Does Lentune help with Construction Contracts Act 2002 compliance?
Yes. The Construction Contracts Act 2002 sets strict content and timing requirements for payment claims and payment schedules, and requires payers holding retention money to keep detailed ledger records. Lentune helps NZ construction businesses generate compliant payment claims, track variations, and manage retentions — with a full audit trail of claims, schedules, and retention movements that supports the record-keeping and process discipline the Act requires.
Does Lentune work with Xero for NZ construction companies?
Yes — Lentune has a native integration with Xero. Lentune sits in front of Xero, validating and coding every project transaction before it posts to your accounts. Xero handles the accounting. Lentune handles project financial control. Given Xero's popularity in the NZ market, that's exactly how Kiwi builders expect their tools to work together.
Is Lentune built in New Zealand?
Yes. Lentune was founded in Christchurch and our support team is based right here in New Zealand. We've built the platform around NZ construction workflows, the Construction Contracts Act 2002, and the Xero-first accounting environment that most Kiwi builders operate in. We know how NZ construction works — because we're part of it.
How can builders manage variations and retentions in construction projects?
Variations and retentions are two of the most common sources of margin leakage in construction — and both are notorious for slipping through the cracks on a spreadsheet. Lentune includes a variation register linked directly to your project budget, with approval workflows and claim integration so scope changes are captured and recovered. Retentions are tracked automatically across both head contracts and subcontracts, with release management and a full audit trail. No more retention spreadsheets. No more missed claims.
What is the easiest construction cost management software for NZ builders to use?
Lentune is designed to be practical and straightforward. Upload your budget and the system tracks every cost against it as they come in. Site staff log hours and expenses on their phones. Finance teams process invoices with AI-assisted data extraction and approval workflows. Project managers see live budget vs actual reports without chasing anyone for a number. Our software is made for humans: easy to learn, and easy to use.
How long does Lentune implementation take?
Lentune implementation typically takes up to eight weeks, with many NZ construction businesses going live sooner. After your demo and discovery call, your dedicated implementation specialist works alongside your team from kickoff to go-live — covering configuration, data migration, training, and weekly check-ins the whole way through.
How can builders improve cost accuracy?
Most cost accuracy problems in construction come from the same few places: invoices coded to the wrong project or cost code, costs that aren't captured until after month end, and variations or claims that fall through the cracks. Lentune tackles all three. AI-powered invoice extraction reduces coding errors, real-time cost tracking means nothing waits until month end, and variation and retention management keeps your commercial items visible throughout the project. Fewer mistakes. Better margins.

Brilliant experience from the whole Lentune team throughout early engagement and then to on-boarding & implementation, very smooth and painless process. Excellent software, very intuitive and easy to use and ticked all the boxes for the AP and project cost control requirements we had.
We have recently joined the Lentune family and it has been such an easy transition and the automation makes life so much easier. Mark has been fabulous to work with while training with weekly catchups and regular emails, nothing was too much trouble for him. Looking forward to working with Lentune now and into the future.
They say time is money - and the amount of time we've saved deploying Lentune has been immeasurable. Our workflow from the past 5 years was re-written within two months of Lentune's introduction. Thank you to Mark and his team for their patient and thoughtful tutorials. The only wish I have is that we had this sooner!
We've been using Lentune for a couple of months now to manage our purchase receipting in Simpro and Xero, and it's made a huge difference. It's sped up our workflow so much that I even checked to see if any invoices had gone missing! Mark's been fantastic with the induction and support — highly recommend.
