SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill removes the manual overhead of building and maintaining integrated financial models by keeping the income statement, balance sheet, and cash flow statement mathematically linked and audit-ready.

Core Features & Use Cases

  • Integrated statement building: Creates fully connected IS, BS, and CF models with working capital schedules, D&A roll-forwards, debt schedules, and retained earnings tie-outs.
  • Template completion: Maps existing Excel model templates, preserves formulas, and populates only the correct input cells for historicals and assumptions.
  • Validation and controls: Runs balance checks, cash tie-outs, and cross-statement integrity tests so projection errors are caught early.
  • Use case: A finance analyst can turn a partially built forecasting template into a complete, linked 3-statement model with scenario-driven projections and clear audit checks.

Quick Start

Ask the assistant to map the attached Excel model template, confirm the tabs and input sections, and then populate the historicals and linked projections while preserving formulas and balance checks.

FAQPage Schema
How do I build an integrated 3-statement financial model in Excel with linked income statement, balance sheet, and cash flow projections?

An integrated 3-statement financial model links your income statement, balance sheet, and cash flow statement using formula-driven projections and historical actuals. Working capital schedules, debt roll-forwards, and retained earnings tie-outs keep the statements mathematically connected and audit-ready.

Can I populate an existing Excel financial model template without overwriting existing formulas?

Yes, you can map an existing Excel financial model template and populate only the correct input cells for historicals and assumptions. This preserves your existing formulas while completing the linked projections and scenario analysis across the three statements.

What is the best way to validate balance sheet and cash flow tie-outs in a financial forecasting model?

The best way to validate financial forecasting models is running cross-statement integrity tests, balance checks, and cash tie-outs. These controls catch projection errors early by ensuring the balance sheet balances and cash flow matches the ending cash position.

How does a working capital schedule connect to the balance sheet and cash flow statement in a three-statement model?

A working capital schedule connects to the balance sheet by projecting current assets and liabilities, while the changes flow into the cash flow statement's operating activities. This linkage ensures the three-statement model maintains mathematical consistency across all projections.

Do I need historical actuals and assumptions to generate formula-driven financial projections?

Yes, historical actuals and assumptions are the only hardcodes required to generate formula-driven financial projections. Everything else in the three-statement model is driven by formulas to maintain integration, scenario analysis capabilities, and cross-statement validation.

Why does my balance sheet not balance when building a three-statement financial model with debt and D&A schedules?

A balance sheet fails to balance when debt roll-forwards, D&A schedules, or retained earnings are not properly linked across statements. Cross-statement checks and cash tie-out validation identify these projection errors by testing whether the income statement, balance sheet, and cash flow remain mathematically connected.
