Building Your Dashboard

Step 1: Define Your KPIs

Sales Dashboard:

• Daily revenue
• Revenue vs goal
• Active customers
• Pipeline value
• Sales rep performance
• Conversion rates
• Average deal size

Operations Dashboard:

• Support queue
• Response time
• Resolution rate
• Team workload
• Customer satisfaction
• Ticket backlog
• Escalated issues

Marketing Dashboard:

• Website traffic
• Leads generated
• Cost per lead
• Conversion rate
• Campaign ROI
• Email metrics
• Social engagement

Step 2: Create Sheet Structure

Sheet 1: Raw Data

• Minimal processing
• Complete records
• Timestamps
• Source system IDs

Sheet 2: Calculated Metrics

• Formulas for KPIs
• Aggregations
• Ratios and percentages
• Trending data

Sheet 3: Dashboard View

• Charts and visualizations
• Executive summary cards
• Key metrics highlighted
• Drill-down capability

Step 3: Build Data Pipelines

Workflow 1: Daily Metrics

Trigger: Schedule (6 AM, 12 PM, 6 PM)

1. Stripe: Daily revenue
2. HubSpot: Deals, pipeline
3. Analytics: Traffic, conversions
4. Support: Open tickets
5. Aggregate and append

Workflow 2: Real-Time Alerts

Trigger: Every 5 minutes

Monitor:

• Revenue drops 20%?
• Support queue > 10?
• Site down?
• API errors?

Send: Slack notifications

Step 4: Create Formulas

Daily Revenue:

=SUMIF(D:D, TODAY(), F:F)

Week-over-Week Growth:

=((B2-B1)/B1)*100

30-Day Moving Average:

=AVERAGE(B1:B30)

Rank Performance:

=RANK(B2, $B$2:$B$100, 0)

Step 5: Build Visualizations

Charts that matter:

• Line charts: Trends over time
• Column charts: Comparisons
• Pie charts: Composition
• Gauges: Progress to goal
• Scorecards: Key metrics
• Heat maps: Performance grids

Real-World Example: SaaS Company

Executive Dashboard:

Top Row (KPI Cards):

• Daily Recurring Revenue: $5,234
• Monthly Recurring Revenue: $157,000
• Active Customers: 1,247
• Churn Rate: 2.3%
• Support Satisfaction: 4.8/5

Middle Section (Trends):

• Revenue trend (90-day line)
• Customer growth (trend)
• Feature adoption (stacked bar)
• Churn trend (line)

Bottom Section (Details):

• Revenue by plan tier (pie)
• Customers by region (map)
• Support by category (bar)
• Team performance (table)

Right Sidebar (Alerts):

• High churn alert
• Payment failures
• API incidents
• Feature bugs reported

Advanced Features

Predictive Metrics

Add forecast to your data:

=FORECAST(TODAY(), historical_range, date_range)

Anomaly Detection

Flag unusual values:

=IF(ABS(B2-AVERAGE(B:B))>STDEV(B:B)*2, "⚠️ Anomaly", "✓ Normal")

Conditional Formatting

Highlight important data:

• Top 10% green
• Bottom 10% red
• Goals met blue
• Trends reversed yellow

Performance Optimization

For large datasets (100,000+ rows):

1. Archive old data: Move 90-day-old data to archive sheet
2. Use tables: Better than ranges for sorting/filtering
3. Limit formulas: Avoid complex calculations in every row
4. Refresh intervals: Update every 15 min, not every minute
5. Delete old data: Keep only necessary columns

Cost Comparison
