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.
