    Measure performance across exact locations. Link your data to ZIP code boundaries to generate instant regional heat maps.What you can track: Demographics: Pinpoint specific population concentrations, like men aged 35–50.Performance: Visualise sales volume per ZIP code to identify your strongest markets.

Group ZIP Codes: Visualize Status

Group multiple ZIP codes by color to represent shared values or status.

Why it matters: This creates an instant visual binary for complex data. You don't need to read the data; you just see the pattern.

Real-world example: Service Coverage

  • Green: Region covered by a service team
  • Red: Region not covered

Link Data to Regions

Upload Excel data and automatically link it to specific ZIP code boundaries. This layers depth onto your visual map. You see the high-level status (covered vs. not covered) by color, but access the hard data with a single click.

  • Visualise status: Use color codes to see who is covered instantly
  • Reveal details: Click any region to open an info box displaying the spreadsheet data attached to that boundary, such as customer counts or service engineer availability

Color Code Vs. Heat Map

Choosing the right visual style determines whether your data is understood or ignored.

  • Color-coded maps: Best for clear, distinct categories (e.g., "Covered" vs. "Not Covered"). Use this for binary or text-based values.
  • Heat maps: Best for showing intensity or density across a range of integer values.

Real-world Example

Mapping population density:

  • Dark red: High density
  • Light pink: Low density
  • The range: Shades in between capture the nuance of the data distribution

Layer Data on a Color-coded ZIP Code Map

A single dataset tells only half the story. Layering additional data points creates a multidimensional view of your market.

How it Works

  • Reuse: Create and save your base color-coded map to use as a template for future analysis
  • Overlay: Plot distinct variables—such as competitor locations—directly onto your service regions to spot threats or gaps instantly

Frequently Asked Questions

Why Map My Excel Data?

The big difference
Spreadsheets are excellent for storing data, but they cannot answer the crucial question: Where? Static rows hide reality. Mapping software instantly transforms those rows into a visual landscape.

The payoff

  • Visualize: Spot customer clusters and territory gaps instantly
  • Decide: Stop guessing based on pivot tables and start executing data-backed strategies

How Do I Visualise My Salesforce Data?

Connect eSpatial directly to Salesforce CRM to plot customer locations instantly.

Why it matters
Lists of addresses hide patterns. Mapping them reveals exactly where your revenue sits.

What You See

  • Density: Spot customer clusters instantly
  • Value: Highlight high-revenue ZIP codes with color coding
  • Status: Visualize account stages or tiers geographically

How Do I Create Fair Territories Quickly?

Use visual tools to group ZIP codes and balance workload instantly. Manual planning leads to uneven patches and burned-out reps. Data-driven design ensures every territory is fair and profitable.

How it works

  • Select: Visually circle a group of ZIP codes on the map
  • Measure: See the immediate impact on total revenue or customer count
  • Assign: Allocate the territory to a rep in seconds, turning a weeks-long process into a quick exercise

How Do I Find Untapped "white Space"?

Overlay your internal customer data with third-party demographic data. Spreadsheets can't show you what is missing. Mapping reveals ZIP codes where your ideal customers exist, but your business doesn't.

The workflow

  • Visualize: Map your current customer footprint
  • Layer: Add market data to highlight high-potential areas
  • Target: Instantly identify underserved ZIP codes to maximize campaign ROI

How Do I Reduce Windshield Time?

Visualize account locations to fix inefficient routes. Lists of ZIP codes hide travel realities. Bad territory design forces reps to drive rather than sell.

The payoff

  • Spot flaws: Identify illogical territory shapes instantly on a map
  • Optimize: Adjust boundaries to create compact, logical routes
  • Sell: Trade drive time for face time with customers

Is This Tool Too Complex?

If your team can use Excel, they can use eSpatial. Adoption fails when tools are hard. We designed this specifically for sales and marketing pros, not data scientists.

The workflow

  • Upload: Drag and drop your spreadsheet
  • Visualize: The platform maps your data automatically
  • Win: Get insights in minutes, with zero IT support required

Why Not Just Use Power Bi?

Power BI puts dots on a map. Dedicated mapping software allows you to manipulate geography to drive revenue.

What you gain

  • Design: Build, edit, and balance sales territories instantly
  • Analyze: Identify white space and measure market penetration deep dives
  • Control: Move beyond static dashboards to dynamic territory management that BI tools cannot handle

How Do I Prove ROI Internally?

Don't sell the map. Sell the money. Leadership doesn't care about pretty reports. They care about efficiency and revenue. Shift the conversation from "visualization" to "measurable outcomes."

The business case

  • Sales productivity: Balanced territories increase quota attainment by up to7% and reduce rep turnover
  • Marketing efficiency: Target high-value ZIP codes to slash customer acquisition costs (CAC)
  • Resource allocation: Stop wasting budget on low-opportunity zones
