Balanced territories from a ZIP list.
Balanced build
Even patches, by the numbers.
Group ZIPs into territories that balance on account count or revenue, so no rep is handed an impossible patch or an empty one.
Balanced by design
Proximity-first
Territories that hang together.
Because it builds on proximity, each territory is geographically tight, not a scatter of distant ZIPs that look even on a spreadsheet but cost a day to cross.
Geographically tight
The Problem
Fair territories are a math problem, not a guess.
Hand-drawn territories end up lopsided: one rep drowns while another runs out of accounts, and both spend too long driving between distant ZIPs.
The Sales Territory Builder groups your ZIP-level accounts into territories that balance on the metric you choose and stay geographically tight, so the map is fair and workable.
How It Works
Three steps to a territory map.
Step 2
Import ZIP-level accounts
Paste, upload, or drag in your book.
Step 3
Set the count and build
Choose how many territories, balance, export to CSV.
