Sales Territory Planning

Why Sales Territory Planning Matters More Than Most Businesses Realise

Sales territory planning is one of those disciplines that many businesses treat as an afterthought — something to sort out once you have a sales team in place, rather than the foundation upon which effective selling is built. Yet the structure of your territories has a direct bearing on how efficiently your team operates, how fairly they are treated, and ultimately how many new clients you win.

Without proper territory planning, you create a situation where some sales people are overwhelmed with prospects while others are chasing a thin market. Motivation suffers, opportunities are missed, and clients in neglected areas never get the attention they deserve. For any business investing seriously in B2B lead generation, poor territory design can undermine even the most well-crafted campaigns.

This guide walks through the key elements of effective sales territory planning — from initial design through to ongoing management and performance measurement.

What Is a Sales Territory?

A sales territory is a defined group of prospects or customers assigned to a particular salesperson or team. Territories can be defined in several ways, and the right approach depends entirely on the nature of your business and your market.

Geographic Territories

The most common approach for field-based sales teams, geographic territories divide the market by location — postcodes, counties, regions, or countries. Geographic territories make logistical sense when face-to-face meetings are important, travel time is a factor, or your product or service has strong regional demand characteristics.

For a UK-based B2B business, geographic territories might be structured around broad regions (North West, Yorkshire, Midlands, South East) or more granular areas depending on the density of your target market and the size of your sales team.

Industry or Vertical Territories

For businesses selling complex solutions where deep sector knowledge matters, dividing territories by industry rather than geography can be highly effective. An industry-based approach allows each salesperson to develop genuine expertise in their vertical — understanding the specific challenges, buying processes, and language of their target market. This is particularly relevant in sectors such as manufacturing, financial services, healthcare, and logistics.

Account Size or Value Territories

Some businesses segment by account size, with dedicated teams or individuals handling enterprise accounts, mid-market, and smaller businesses separately. This ensures that high-value prospects receive the attention and seniority they warrant, while smaller accounts are served efficiently without consuming disproportionate sales resource.

Hybrid Approaches

In practice, many UK businesses use hybrid territory structures — perhaps geographic at the broadest level, with further segmentation by industry or account size within each region. The key is that the logic is clear, the boundaries are defined, and every prospect falls somewhere within the structure.

The Data You Need Before Designing Territories

Good territory design is a data exercise. Before drawing lines on a map or assigning sectors to individuals, you need a clear picture of your market. This means understanding where your prospects are concentrated, the relative value of different segments, the competitive landscape, and the practical capacity of your sales team.

Market Mapping

Start by mapping your total addressable market. For most B2B businesses, this means pulling together a data picture of all the companies in the UK that could plausibly buy from you — filtered by industry, company size, location, and any other relevant criteria. Professional lead generation partners can help you build and clean this data set, ensuring your territory planning is built on accurate, up-to-date information rather than outdated lists.

Historical Performance Data

If you have an existing sales operation, your own performance history is invaluable. Analyse where your existing clients are located, which sectors have converted best, and which geographies or verticals have proven harder to crack. This data should inform how territories are designed and where you allocate your strongest performers.

Travel and Capacity Considerations

For field-based teams, travel time is a genuine constraint. A territory that looks manageable on paper can become exhausting and inefficient if the geography requires constant long-distance travel. When designing geographic territories, consider driving times between key prospect clusters, not just straight-line distances. A well-designed territory allows a salesperson to conduct multiple meetings in a day without spending most of their time behind the wheel.

Balancing Your Territories

The most common mistake in territory planning is imbalance — creating territories of wildly different size, opportunity, or workload. Even with the best intentions, imbalanced territories create inequity and inefficiency.

Balancing for Opportunity

Territories should offer roughly comparable revenue opportunity wherever possible. A salesperson in a territory containing Manchester, Leeds, and Sheffield is working with a very different market density to a colleague covering rural East Anglia. If you commission on results without accounting for this, you will find it difficult to retain talent in harder territories and risk complacency in easier ones.

Balancing for Workload

Opportunity and workload do not always align. A territory with a large number of smaller accounts may be similar in revenue potential to one with fewer but larger accounts, yet the workload involved in servicing and developing them is very different. Account count, meeting frequency expectations, and the complexity of relationships all factor into genuine workload, not just headline opportunity.

Accounting for New Business vs Account Management

If your sales team handles both new business development and ongoing account management, territories need to account for both. As a salesperson builds their client base within a territory, their capacity for new business activity naturally reduces. This is a healthy development but needs to be planned for — either by adjusting territory scope over time or by separating new business and account management responsibilities.

Territory Planning and Lead Generation Campaigns

Your territory structure should directly inform how you plan and execute outbound telemarketing and lead generation campaigns. Campaigns that are designed around territory boundaries give your sales team warm, geographically or sectorally relevant leads that they can follow up quickly and contextually.

Working with a UK-based call centre to run territory-by-territory prospecting campaigns ensures that each salesperson receives a steady flow of qualified prospects within their patch. This kind of structured approach also makes it easier to measure campaign performance by territory — identifying where the calling is generating strong results and where different messaging or targeting might be needed.

At XL Marketing, we regularly work with clients to design calling campaigns that map precisely to their territory structure, ensuring that leads are distributed fairly and followed up effectively. B2B appointment setting works best when the prospect is handed straight to the right person — and that only happens with clear territory design.

Reviewing and Refining Your Territories

Territory planning is not a one-off exercise. Markets change, team composition shifts, and the relative opportunity in different sectors or geographies evolves over time. Building a regular review cycle into your sales management process ensures your territories remain fair, efficient, and aligned with your business objectives.

Annual Review as a Minimum

At minimum, review your territories once a year — typically aligned with your financial year or your annual business planning cycle. This review should look at performance data by territory, changes in your market, headcount changes, and any shifts in your product or service offering that might affect where opportunity lies.

Responding to Growth

When your team grows, territories will need to be redrawn. This can be a sensitive process, as established salespeople may be reluctant to cede part of their patch. Handle this with transparency — explain the rationale, acknowledge the disruption, and where possible protect existing client relationships while opening up new areas for development.

Using Data to Refine

The best territory planning teams use ongoing performance data to continuously improve their approach. Track not just revenue by territory, but activity metrics — calls made, meetings held, conversion rates at each pipeline stage. This granular data reveals where territories are working well and where structural changes might improve performance.

Common Territory Planning Mistakes to Avoid

Even experienced sales leaders make predictable mistakes when designing territories. Awareness of these pitfalls helps you avoid them.

Designing territories around individuals rather than the market is a common error — creating a patch that suits a particular salesperson rather than one that reflects genuine market opportunity. When that person leaves, the territory becomes awkward to reassign.

Neglecting to account for existing client distribution is another frequent issue. When a territory changes, client relationships are disrupted. Minimise this by tracking where existing clients sit and designing boundaries that keep natural client clusters within a single territory wherever possible.

Finally, failing to communicate the design rationale to your team undermines buy-in. Salespeople who understand why territories are structured as they are — and who can see that the process has been fair and data-driven — are far more likely to engage positively with the outcome.

Getting the Foundation Right

Sales territory planning might not be the most glamorous part of running a sales operation, but it is one of the most consequential. Get it right, and your team operates efficiently, your campaigns reach the right prospects, and your pipeline grows predictably. Get it wrong, and even excellent salespeople will struggle to deliver consistent results.

If your business is investing in lead generation, appointment setting, or outbound marketing, aligning those activities with a clear, well-designed territory structure will significantly improve your returns. Start with the data, design for balance, and review regularly — and your sales territory plan will be one of the most valuable tools in your growth strategy.
