Associate Director
So for us, Mastt allows us to have a single source of truth, as all the costs of instructions are in one centralised location, including payment claims. Because it’s not an Excel file, it can’t be manipulated to make a number work. It kind of pulls through the true cost.

Auckland Regional Manager

Associate Director
Great CAPEX management tool with intuitive infographics. The dashboard view of projects is something that we did not have before Mastt. I can see that it will deliver a clearer and more intuitive understanding of capital projects to executives.

Mastt was easy to use and set up. It uses a lot of cost management principles that clients and contractors would be familiar with but takes away a lot of user error that spreadsheets bring. It also has the power to combine multiple projects into programs or portfolios to filter data for management-level analysis and direction.

Associate Director
Mastt’s real-time updates allow our team to keep updated on progress and provide updates to clients whenever required. Mastt has saved our team significant time and effort by becoming a ‘one-stop shop’ for managing the financial elements of 65+ projects.

Fund Manager
Mastt allows us to complete our cost management activities in a more efficient way and gives us more time to focus on technical project management activities that we face in the role of project manager.

Project Manager
It's a great reporting tool for the college because it gives us a lot of transparency and visibility of information in regard to contracts, the contract sums, the actual spending against the variations, and where we are at.

Business Manager
It has been great to have the visibility to review our variations and ensure that we are getting value for them. We were also able to easily identify that we had circa 90k in credits, which prompted us to follow up. We are getting great value out of Mastt when we can do things like this.

Business Manager
Mastt helps reduce the opportunity for errors in cash flow and budgeting and provides insights into aggregated data and program trends that we need.

Project Director
Construction project cost management software brings budgets, contract commitments, changes, payments, and forecasts into one system. It helps owners and their project teams understand what has been committed, what has been paid, and what the completed project is expected to cost. This supports financial oversight from the initial budget through project closeout.
Mastt connects cost records so your team spends less time reconciling separate spreadsheets. Its cost tracker brings budget, contract, payment, and forecast information into a shared view, with totals that update as records change. This makes it easier to maintain a consistent financial position without manually rebuilding calculations for each report.
Yes. You can copy budget names and amounts from Excel into Mastt, reducing the need to retype each line. Mastt’s project budgeting tools support budgets and sub-budgets for organizing costs by phase, work package, or category. Your spreadsheet data needs to follow the required column format, and sub-budgets are added separately from the main budget import.
Yes. Mastt links each contract to the relevant project budget and keeps its changes and payments together. Its contract management tools let you review individual contract values alongside the combined commitments across your project. This helps you understand how separate consultant, contractor, and supplier agreements contribute to the overall cost.
Mastt compares your budget with the expected final project cost, known as the Estimate at Completion (EAC). This forecast includes committed costs and anticipated costs for remaining work. You can review the difference at project and budget-line levels to identify where costs are expected to exceed the available budget and investigate what is driving the increase.
Yes. Mastt includes forecast and pending change orders in the project’s forecast while keeping them separate from approved contract changes. Its change order management tools help you assess potential cost exposure while decisions are still being made. Approved changes then update the relevant contract value and committed costs.
Yes. Mastt lets you include forecasts for uncommitted costs, such as anticipated work and contingency allowances, alongside existing contract commitments. This gives you an expected final cost that accounts for work still to be contracted. You can refine those allowances as the scope, pricing, and contract awards become clearer.
Yes. Mastt’s cash-flow forecasting lets you plan expected payments by month and compare those projections with payments recorded as paid. You can adjust the timing as delivery plans and forecasts change. This helps your project and finance teams anticipate funding needs and understand differences between planned and actual cash outflows.
Yes. Mastt generates project cost reports using recorded budgets, commitments, changes, forecasts, and payments. Reports can show the difference between the budget and expected final cost, with breakdowns by budget line or cost category. You can export them for owner and client reviews without manually consolidating separate cost spreadsheets.
Mastt uses AI data entry to extract details from documents and help prepare contract, payment, and change order records. Its AI payment verification checks submitted documents against configured contract requirements and flags items needing attention. Your team reviews the extracted information and verification results before accepting records or approving payments.
