Audit accounts payable with Windsurf Cascade

The `list_bills` tool pulls unpaid liabilities directly into your Windsurf workspace. Cascade analyzes these pending obligations, tracks due dates, and cross-references them against your general ledger without needing manual exports. When you ask Cascade to review cash flow, it runs `get_bill` on high-value items to parse line items. The agent then drafts payment schedules in your local workspace files, matching your actual cash-on-hand metrics.

Map vendor profiles using this MCP Server

Use the `list_vendors` tool to extract active supplier records directly into Windsurf's context window. This MCP Server lets your agent inspect specific vendor terms and historical transactions instantly. Cascade reads this data, runs `get_vendor` to pull tax details, and flags missing W-9 indicators. It then writes a clean Python script in your editor to automate vendor verification reports.

Reconcile client invoices autonomously in Cascade

The `list_invoices` tool lets Cascade scan outstanding receivables directly from your BILL (Bill.com) account. Your agent matches incoming payments against outstanding balances by querying `get_invoice` for specific invoice metadata. Cascade uses this live financial data to update your local tracking spreadsheets automatically. You get a clear picture of outstanding debt without leaving your development environment.
