01 / Overview
AltisCassa is an all-in-one system that centralises a business’s cash operations, counterparty obligations, project budgets and corporate reporting, handling multi-currency transactions, invoice flows and financial reports in real time.
02 / The problem
Cash, debts and project budgets were kept in separate Excel files. Month-end profit and loss meant merging them by hand, and nobody had a clear real-time balance per currency.
03 / Our approach
Clean Architecture with separate domain, application, infrastructure and API layers. Every operation leaves an audit trail, and deletions are soft-only, so financial data is never lost for good.
04 / The result
Profit and loss, cash flow, turnover, VAT and ageing reports are generated instantly, and a Ctrl+K command palette gives one-step access to the advanced features.
