About The Project

Calxa is leading budgeting and cashflow forecasting software for small and non-profit businesses and organizations located in Australia and New Zealand. It saves time, is easy to use, and delivers professional reports in a fraction of time used in spreadsheets.

Shortcuts. It applies shortcuts to multiple lines, whole budgets or individual fields, and watches automatically updated totals.

Multiple budgeting versions. Unlike spreadsheets, multiple budget versions are easy to manage. You copy budgets from one version to another and report on any version.

Report templates. You select from over forty report templates, interpret the reports for non-accountants, forecast cashflow and balance sheet, compare budgets and report on KPIs.

File management. Data is stored locally with SQL Server or online with Microsoft Azure.


Simplify and Make Better Decisions

Make your management reports easier and create better, more accurate and professional-looking insights. Accurate information in a readable, understandable format is the basis of sound decision-making.


Save time

Wizards prepare budgets and pre-made templates, reduce time. Workflows automatize processes.


Improve accurancy

Linking directly to the accounting data ensures full transparency and guarantees reliability.

Business value

Calxa uses accounting system data as actual and lets users edit and calculate budgets and cashflow forecasts. Calxa executes calculations and generates highly customizable reports.
