As their business grew, the Sentinel Homes Waikato team had three key frustrations:

1. Laborious data entry

Accounts Manager Haley Paterson estimated that 90% of her workload entailed manually inputting and uploading supplier invoices into their accounting software, MoneyWorks. “It was very, very time consuming,” says Haley.

2. Manual process

The invoice approval process was also manual, creating very little visibility around invoices awaiting credit, on hold or even in dispute with suppliers. For Managing Director Nate Alley, this meant there was a “lack of transparency in the audit trail.”

3. Paper-based POs

Project Managers could only raise handwritten POs via triplicate books whilst out and about. Again, this created data entry for the accounts team, and matching invoices to written purchase orders was a long-winded process.


Lentune’s integrated, cloud-based business automation platform ticked the right boxes for Sentinel Homes Waikato, including integrating with MoneyWorks. The team also appreciate that Lentune is a local company; open to taking on feedback and making changes to improve. Sentinel Homes Waikato now use three Lentune modules:

  1. Invoice Automation
  2. Purchase Order Automation
  3. Timesheet Automation


1. Time saving

“The business is growing so fast, that the invoicing I input has nearly tripled,” says Haley. But thanks to Lentune’s Invoice Automation, she’s saving “at least 20 hours a week.” As a result, Haley’s been able to concentrate on the management side of finance instead of data entry. Not only is this good for the bottom line, but it’s improving Haley’s job satisfaction. Getting the best out of his team is clearly important to Nate. “I’m stoked that it’s saving Haley time, because her strength isn’t in inputting invoices,” he says.

The newly added Timesheets module is saving time too. Timesheet automation for non-salaried staff has allowed back-costing to be tracked and has increased transparency across the business. Expenses and labour worked can be coded specifically to jobs and non-job items. Sentinel Homes Waikato’s Quantity Surveyor Ashley Mason is already seeing the benefits of this. “I can complete back-costing much quicker than what I was previously,” Ashley says.

2. Visibility

The Sentinel Homes Waikato team are grateful for the visibility that Lentune gives them. They now use the Lentune platform to communicate directly to suppliers and the internal team to clear up discrepancies and invoicing issues. This provides a record of communications, so it’s always clear why an invoice is on hold.

Purchase Order Automation has also increased visibility. Project Managers can now raise purchase orders wherever they are, using the Lentune app. And because everything within Lentune is linked, each purchase order is automatically matched to the corresponding invoice. “Having the PO side by side with the invoice is awesome,” says Haley, as it gives greater visibility to the whole team in relation to what was ordered compared to product charges against a job.


By removing data entry and automating admin processes, Sentinel Homes Waikato have freed up time to focus on growth and profitability. Plus, cloud-based access to documents and communications has increased visibility, allowing the team to easily review invoice status and gain real-time insights into data.
