2. Prerequisites

• Tools: Power BI Desktop, Power BI Service (Pro/Premium).
• Data Sources: Bank APIs, QuickBooks/Xero, Excel/CSV files.
• Skills: Basic DAX (Data Analysis Expressions) knowledge.

---

3. Step 1: Data Collection & Structuring

Data Sources:

• Transactions: Bank statements, invoices, payments.
• Forecasts: Budgets, sales pipelines.
• Liquidity Metrics: Current assets/liabilities, credit lines.

Structuring Data:

• Create tables:
  • Transactions: Date, Amount, Type (Income/Expense), Category.
  • Forecasts: Month, Predicted Income/Expense.
  • Liquidity Metrics: Current Assets, Liabilities, Credit Limits.

---

4. Step 2: Connect Data to Power BI

• Import Data: Use Power Query to connect to Excel, APIs, or databases.
• Clean Data: Remove duplicates, handle missing values, standardize formats.
• Data Modeling:
  • Link tables via Date and Category fields.
  • Create a Calendar Table for time-based analysis.

5. Step 3: Build the Dashboard

A. Real-Time Tracking

• Visuals:
  • Cash Flow Trend: Line chart (Date vs. Net Cash Flow).
  • Current Balance: Card visual (SUM(Income) – SUM(Expenses)).
  • Top Expenses: Bar chart (Category vs. Amount).

DAX Formulas:

Net Cash Flow = SUM(Transactions[Income]) - SUM(Transactions[Expenses])  
Running Total = CALCULATE([Net Cash Flow], FILTER(ALL('Calendar'), 'Calendar'[Date] <= MAX('Calendar'[Date])))  

B. Forecasting

• Visuals:
  • Forecast vs. Actual: Combo line chart (Actual vs. Predicted Cash Flow).
  • Use Power BI’s Analytics Pane for built-in forecasting.

DAX Formula:

6-Month Forecast = AVERAGEX(DATESINPERIOD('Calendar'[Date], LASTDATE('Calendar'[Date]), -6, MONTH), [Net Cash Flow])  

C. Liquidity Insights

• KPIs:
  • Current Ratio: Total Assets / Total Liabilities.
  • Quick Ratio: (Assets – Inventory) / Liabilities.

DAX Formulas:

Current Ratio = DIVIDE(SUM(Liquidity[Current Assets]), SUM(Liquidity[Current Liabilities]))  
Quick Ratio = DIVIDE(SUM(Liquidity[Current Assets]) - SUM(Liquidity[Inventory]), SUM(Liquidity[Current Liabilities]))

6. Step 4: Automate & Share

• Refresh Data: Use Power BI Gateway for live connections.
• Publish: Share to Power BI Service and set data-driven alerts.
• Mobile Optimization: Enable responsive layouts.

---

7. Step 5: Best Practices

• Update Regularly: Refresh data daily/weekly.
• User Training: Simplify navigation with tooltips/bookmarks.
• Security: Apply row-level security for sensitive data.
