Build Faster, Smarter Budgets Without Leaving Excel
A3 transforms Excel into a robust budgeting engine—combining the familiarity of spreadsheets with the structure of an enterprise-grade platform. Data flows directly from your source systems into connected models, allowing teams to collaborate in real time and update budgets without overwriting each other’s work. Whether you’re managing departmental inputs, top-down targets, or rolling forecasts, A3 keeps everything centralized, auditable, and lightning fast.
Turn Excel into a fast, flexible budgeting engine your whole team can trust.
Most budgeting platforms promise control and consistency, but they come at the cost of flexibility. A3 takes a different approach. We give finance teams a dynamic, Excel-native model that works exactly the way the business does. Build bottoms-up budgets with full driver logic, adjust structures as priorities shift, and run forecasts that reflect what’s really happening, not what the software allows. You get enterprise-grade structure without the slowdown, with full auditability, collaboration, and version control built in. As new information comes in or business conditions change, updates can be made quickly and confidently without breaking the model or starting from scratch. Whether you’re building departmental budgets, rolling up a global P&L, or managing recurring reforecasts, A3 gives you the speed, accuracy, and flexibility to plan with confidence. Budgeting is no longer a quarterly fire drill or a one-time exercise. It becomes a responsive, living process that moves as fast as your business.
