## Description

You can stop guessing when your money will actually arrive. This MCP acts as a forecasting engine that maps out your cash flow timelines by looking at invoice issue dates and contractual terms. Instead of manually calculating dates for every installment, you let your AI client handle the math. You can check if your contract terms make sense using business logic validation or aggregate your expected totals for any specific month or quarter. If a client is running behind, you can model exactly how those delays shift your entire financial outlook. It's a direct way to turn static invoice lists into a dynamic roadmap for your business liquidity.
