Gantt Visualization: Interactive chart that plots sales milestones over time using a Gantt-style timeline. Displays forecasted revenue by date.
Forecast Summary: Consolidates monthly and quarterly forecasts, win rates, probability adjustments, and total expected revenue.
Data Dictionary & Instructions: Reference guide explaining fields, formulas, color codes, and best practices for startup use cases.

Table Structures & Columns

Sales Pipeline (Main Data Table)

Column Name	Data Type	Description & Constraints
Deal ID (Auto)	Text/Number (Auto-generated)	Unique identifier for each deal. Uses =TEXT(TODAY(),"yyyymmdd")&ROW() to auto-assign.
Customer Name	Text	Name of the prospective or existing customer.
Deal Value ($)	Numeric (Currency)	Dollar amount of the contract. Must be > 0.
Expected Close Date	Date	Planned date of deal closure. Set using calendar picker.
Sales Stage	Text (Dropdown)	Possible values: Prospecting, Demo Scheduled, Proposal Sent, Negotiation, Closed Won/Lost. Uses data validation.
Probability (%)	Numeric (0–100)	Benchmark for likelihood of closing. Default: 25% for Prospecting → 95% for Negotiation.
Forecast Category	Text (Dropdown)	Select: "High Confidence", "Medium Confidence", "Pipeline" based on stage and history.
Milestone Dates (e.g., Onboarding Start, Contract Signed)	Date	Custom field per deal—can be expanded for multiple events.

Gantt Visualization Sheet

This sheet contains a timeline-based chart using Excel’s stacked bar feature to represent sales deals as horizontal bars. Each bar spans from the "Expected Close Date" to its start date (or deal initiation). The width of the bar reflects forecasted revenue contribution.

Forecast Summary

Column Name	Data Type	Description
Month/Quarter (e.g., Q2 2024)	Date (Grouped)	Monthly or quarterly summary.
Total Forecast ($)	Numeric	SUMIFS of all deals where Close Date falls in this period.
Pipeline Value ($)	Numeric	Sum of all deals at Prospecting–Negotiation stages.
High Confidence Revenue ($)	Numeric	Sum of deals with >75% probability and "Closed Won" status.
Win Rate (%)	Numeric (0–100)	Calculated as: Closed Won Deals / Total Deals * 100.

Formulas Required

Deal Weighted Value: = [Deal Value] * [Probability (%)]/100 → used for forecasting accuracy.
Forecast by Month: =SUMIFS('Sales Pipeline'!$D:$D, 'Sales Pipeline'!$C:$C, ">="&StartDate, 'Sales Pipeline'!$C:$C, "<="&EndDate) → dynamically pulls revenue for each time period.
Milestone Status Indicator: =IF(ISBLANK(E2),"Pending",IF(TODAY()>E2,"Overdue","On Track")) → helps identify delayed deals.
Color Code Logic (in Gantt chart): Conditional formatting rule using =AND(CloseDate<=TODAY(), Probability>=90%) for green; =AND(CloseDate>TODAY(), CloseDate

Conditional Formatting

Apply these rules to enhance readability and identify risks:

Overdue Deals: If "Expected Close Date" is before today, highlight row in red.
Pipeline Stage Coloring: Apply color gradients by stage (e.g., blue for Prospecting → green for Closed Won).
Gantt Bars: Use gradient fill based on "Forecast Category" to distinguish High/Medium/Low confidence deals.
Risk Alerts: Highlight any deal with probability <30% and expected close date in next 14 days.

User Instructions

Open the template and go to the "Sales Pipeline" tab.
Add new deals using the table structure. Fill in all mandatory fields: Customer Name, Deal Value, Expected Close Date, and Sales Stage.
Update probability based on deal progress (e.g., 25% for Prospecting → 90% for Negotiation).
Navigate to "Gantt Visualization" to see a real-time timeline of your sales pipeline. Bars will auto-adjust based on data changes.
Review the "Forecast Summary" sheet weekly—this shows total expected revenue, trends, and win rate performance.
Use the "Data Dictionary & Instructions" tab for troubleshooting and best practices (e.g., how to handle pipeline churn).

Example Rows (Sales Pipeline)
