How to Split Sales Territories Fairly Between Reps

Why Fair Territory Division Is Harder Than It Looks

Ask any sales manager whether their territories are fair and most will hesitate. They know, intuitively, that some territories are better than others. One rep drives 80 km between customers across a rural area while another covers a dense industrial precinct within 10 km of the depot. One territory has three anchor accounts that generate 60% of its revenue, while another has 50 small accounts that each need the same visit time but generate a fraction of the revenue.

Fair territory design is one of the most important decisions a field sales manager makes — and one of the most frequently made badly. This guide covers the four dimensions of territory fairness, the methods for designing equitable territories, and how to navigate the politics of territory redesign with your team.

The Common Mistake: Splitting by Geography Only

The most common territory design mistake is dividing a map into equal-sized geographic zones and assigning one rep to each. It looks fair — each rep has the same area. But equal area does not mean equal opportunity or equal workload.

In South Africa, this problem is particularly acute. A Gauteng rep covering Sandton and Randburg is driving through some of the most commercially dense territory in the country. An equivalent area in the Northern Cape or Limpopo might contain a tenth of the customers and a fraction of the revenue potential. Equal area, wildly unequal everything else.

The same problem exists at a local level. A rep assigned to a dense industrial area in Germiston has a different workload than a rep assigned to a residential suburban corridor in Pretoria, even if the geographic areas are similar in size.

The Four Dimensions of Territory Fairness

True fairness requires balancing four variables simultaneously:

1. Revenue Potential

What is the total annual revenue that could be generated from the accounts in each territory? This is not the same as current revenue — it includes untapped potential from accounts that are buying less than they could, or prospects that have not yet been converted.

When territories have very different revenue potential, your compensation structure amplifies the unfairness. If one rep has a territory with R5 million potential and another has R2 million potential, and both are on the same commission rate, the first rep will always earn more — regardless of effort or skill.

2. Workload

Workload is the total time required to serve all accounts in the territory properly. It depends on:

• Number of accounts: more accounts mean more visits
• Visit frequency: your A-tier accounts need weekly visits; C-tier accounts might need monthly
• Time per visit: some customers need 20 minutes per visit, others need 90 minutes
• Administrative work: some accounts generate more order complexity, credit issues, or complaint resolution

A rep with 30 large accounts may have a higher workload than a rep with 80 small accounts — or vice versa, depending on visit length and frequency requirements.

3. Travel Time

Geographic area does not equal travel time in South Africa. Johannesburg peak-hour traffic means that two accounts 15 km apart could require 45 minutes of travel. A rural rep might cover 200 km in the same time with no traffic. Your territory design must account for realistic travel time, not map distance.

Route efficiency also matters. A territory where all accounts are clustered in a logical route is far more workload-efficient than a territory of the same size where accounts are scattered and require constant backtracking.

4. Account Complexity

Some accounts require far more relationship investment than their revenue numbers suggest. A politically complex account — where the buying decision involves multiple stakeholders, where there are ongoing service issues, or where the relationship is new and needs nurturing — demands more of a rep's time and skill than a straightforward reorder account.

Account complexity is the hardest dimension to quantify, but ignoring it means some territories are systematically harder to manage than others.

Use SalesRep Software's territory management tools to map your accounts and analyse these four dimensions before designing territory boundaries.

Methods for Territory Design

Account-Based Assignment

Assign a defined number of accounts to each rep based on workload analysis. First, calculate the time required to serve each account properly (visits per month × time per visit + travel time). Then divide the total into equal workload buckets and assign accounts to each rep based on proximity.

This method is labour-intensive to set up but produces the most workload-equitable result. It works well for businesses with well-defined account visit requirements.

Geographic Clustering

Group geographically proximate accounts into clusters and assign each cluster to a rep. The rep's territory is a logical geographic area that minimises travel time. Start with natural geographic boundaries (suburbs, industrial nodes, towns) and adjust for workload imbalance.

This is the most intuitive method for reps to understand and for managers to explain. The disadvantage is that geographic clusters may have very different revenue potential or account complexity.

Revenue-Weighted Design

Design territories so each has approximately equal revenue potential, regardless of geographic size or account count. If total territory revenue potential is R30 million and you have six reps, each territory should have approximately R5 million in potential.

This method is fairest for commission-based remuneration but may result in very different workloads — a high-potential territory may have fewer, larger accounts that require less travel but more sophisticated selling skills.

Hybrid Approach

The most effective territory designs use a hybrid: start with geographic clustering for travel efficiency, then adjust account assignments within and across clusters to balance revenue potential and workload. The result is not perfectly equal on any single dimension, but is reasonably balanced across all four.

How to Identify Whether Your Current Territories Are Unequal

Before redesigning territories, use your data to understand what the current imbalance looks like. Look at:

• Revenue per rep: if the range between your highest and lowest-earning rep is more than 30% on equivalent commission rates, investigate whether territory potential is the cause
• Call frequency compliance: if one rep consistently completes fewer visits than their call cycle requires, investigate whether travel time is making the cycle unrealistic
• Conversion rates: if one rep converts new accounts at a much lower rate than others, consider whether they are covering an inherently lower-potential territory
• Overtime and stress: if one rep is consistently working longer hours without higher revenue, their territory may have a higher workload than their peers

Sales analytics that track visits, revenue, and route efficiency by rep make this analysis straightforward — but even a basic spreadsheet comparison of key metrics by territory will reveal where imbalances exist.

The Politics of Territory Redesign

Territory redesign is politically sensitive. A rep who has worked a territory for three years has relationships with every account. A productive territory feels earned. Being asked to give up a high-potential account to rebalance the team feels like punishment for success.

Handle the politics carefully:

Be transparent about the methodology: show reps the data that demonstrates the imbalance. It is harder to object to a process that is visibly fair than to a decision that appears arbitrary.

Involve senior reps in the design: not to let them choose their own territories, but to get input on account complexity, relationship dynamics, and travel realities that the data may not capture.

Phase changes where possible: if a major redistribution is necessary, implement it over six months rather than immediately. Give reps time to adjust and hand over relationships properly.

Acknowledge the disruption: territory changes are disruptive, even when they are fair. Acknowledge this honestly and provide support during the transition.

Review Cadence: How Often Should Territories Be Rebalanced?

Territories should be formally reviewed annually, with minor adjustments made as needed throughout the year for:

• Significant account wins or losses that shift territory potential
• Addition of new reps to the team (expansion scenarios)
• Rep resignations that require redistribution
• Geographic expansion into new areas

A light annual review — comparing the four fairness dimensions across the team — prevents the gradual drift that occurs as the business grows and changes. Territories that were balanced two years ago may be significantly unequal today because some accounts have grown dramatically while others have declined.

Getting territory design right from the start is far easier than trying to rebalance an inequitable structure that has become entrenched.
