The B2B Salesperson as a Boundary Spanner

A salesperson can win a contract without having built the relationships required to deliver it successfully. That is one of the overlooked challenges in complex B2B sales.

We often evaluate salespeople by their ability to identify opportunities, influence decision-makers, negotiate and close deals. These activities are important, but they represent only part of the value a successful B2B salesperson must create.

In many industries, the real commercial challenge is not simply persuading a customer to buy. It is connecting the right people, knowledge and capabilities across two organisations to ensure that what has been promised can actually be delivered.

This requires a different understanding of the salesperson's role. The successful B2B salesperson is not merely a relationship manager or dealmaker.

The salesperson is a boundary spanner - someone who connects people across organisational boundaries to create value that neither organisation could achieve as effectively in isolation.

Better sales networks are not necessarily bigger networks

In their Harvard Business Review article Better Sales Networks, Tuba Üstüner and David Godes challenge the conventional assumption that more contacts automatically produce better sales performance.

Their argument is that different network structures create different advantages throughout the selling process. Identifying opportunities requires access to timely market information. Building customer commitment requires relationships that provide credibility and influence. Developing solutions requires access to relevant knowledge and capabilities. Closing a deal may require mobilising trusted references.

The implication is significant. A salesperson should not simply aim to know more people. The salesperson should develop the right network for the commercial task at hand.

This principle becomes even more important when we extend it beyond the sales process itself. In complex B2B relationships, the salesperson must build and activate networks both within the customer's organisation and within their own company. The purpose is not merely to secure the order. It is to create the conditions for a successful delivery and a sustainable customer relationship.

The two networks every B2B salesperson must understand

Consider a company selling a complex technical solution, professional service or business-critical implementation. The commercial relationship may begin between a salesperson and a purchasing manager or senior decision-maker. But the success of the solution will often depend on many other people.

Within the customer's organisation, these may include operational managers, technical specialists, finance, procurement, end users and senior leadership. Within the supplier's organisation, successful delivery may require product specialists, operations, engineering, customer success, finance, project management and service delivery.

The salesperson operates at the intersection of these two organisational systems. That creates two equally important networking responsibilities.

1. Building the customer network

A strong customer network helps the salesperson understand how the customer actually operates. It provides access to different perspectives, reveals organisational dependencies and creates a more complete picture of what successful delivery requires.

A relationship with the economic buyer may explain why the investment matters. A relationship with operations may reveal what implementation will demand. A conversation with end users may uncover practical challenges that were never included in the original requirements. And engagement with finance, procurement or IT may expose constraints that could otherwise delay or undermine the project.

These relationships are not simply additional sales contacts. They are essential sources of information for developing the right solution. A salesperson who only knows the decision-maker may understand the buying decision without understanding the conditions for successful implementation.

2. Building the internal network

The second responsibility is equally important - and frequently underestimated. The salesperson must understand the capabilities, priorities and constraints of their own organisation.

Who possesses the technical expertise required to assess the customer's challenge? Who can determine whether a proposed solution is operationally feasible? Who understands the implementation risks? Who will ultimately be responsible for delivering what the salesperson promises?

Research on internal selling demonstrates the importance of salespeople accessing and coordinating resources across their own organisations to support customer-facing activities. This means that internal networking is not merely an administrative necessity. It is a commercial capability.

The salesperson must be able to mobilise expertise, establish internal commitment and ensure that the organisation understands what the customer is trying to achieve.

A strong external network creates customer understanding. A strong internal network creates the ability to act on that understanding. The value emerges when the salesperson connects the two.

Five reasons boundary-spanning salespeople create better commercial outcomes

1. They uncover the customer's real problem

Customers do not always enter a buying process with a complete or shared understanding of their own requirements. Different stakeholders may have different expectations of the proposed solution.

A senior executive may be focused on strategic impact, while operations is concerned about implementation complexity and end users are worried about disruption. A salesperson with relationships across the customer organisation can identify these differences before they become delivery problems.

This creates a more accurate understanding of the customer's situation and helps the supplier avoid designing a solution around an incomplete brief.

2. They connect customer needs with the right internal expertise

Complex solutions rarely emerge from the salesperson's knowledge alone. They require collaboration between commercial, technical and operational specialists.

Research on solution selling highlights the importance of boundary-spanning salespeople in developing solutions and communicating their value to customers. The salesperson's contribution is therefore not necessarily to possess every answer.

It is to know which expertise is required, when to involve it and how to translate between customer requirements and internal capabilities. This makes the salesperson an integrator of organisational knowledge.

3. They reduce the gap between what is sold and what is delivered

One of the most damaging situations in B2B relationships occurs when the sales process creates expectations that the delivery organisation cannot fulfil.

The commercial team may promise a particular outcome, timeline or degree of customisation without fully understanding the operational implications. When the contract is signed, responsibility moves to colleagues who were insufficiently involved in developing the solution.

The result can be frustration, internal conflict, reduced profitability and declining customer confidence. A boundary-spanning salesperson works to prevent this disconnect. By involving delivery specialists early and connecting them with relevant customer stakeholders, the salesperson helps establish shared expectations before commitments become contractual obligations.

The sale and the delivery become parts of the same value-creation process.

4. They create stronger organisational relationships

When the customer relationship depends entirely on one salesperson and one buyer, it is vulnerable. People change roles, priorities shift and relationships can disappear.

A broader network creates connections between the organisations rather than merely between two individuals. Technical specialists can collaborate with technical specialists. Operational teams can establish working relationships. Senior leaders can develop a shared understanding of strategic priorities.

Research examining B2B selling from a network perspective demonstrates the importance of understanding relationships at interpersonal, organisational and wider network levels.

For the salesperson, the objective is therefore not to control every customer interaction. It is to help establish the relationships that make the overall partnership more effective.

5. They turn network access into commercial performance

Knowing the right people is valuable, but access alone is insufficient. The salesperson must also be capable of using that access to construct solutions, coordinate activities and progress commercial opportunities.

Research published in Production and Operations Management examines the interaction between salespeople's social capital and their ability to execute transactions effectively. Its findings reinforce an important distinction: network position and task-related capability must be considered together.

This provides a useful perspective on commercial performance. The strongest salesperson is not necessarily the person with the largest network. It is the person who can activate relevant relationships to create meaningful customer outcomes.

The salesperson as a boundary spanner

The term boundary spanning describes activities that connect individuals, groups or organisations across established boundaries. In B2B sales, these boundaries may be functional, hierarchical, technical, cultural or organisational.

A salesperson might need to connect a customer's operational challenge with the supplier's technical expertise. They may need to translate a strategic business objective into practical implementation requirements. They may also need to reconcile conflicting expectations between customer stakeholders or create internal support for a commercially important opportunity.

The salesperson consequently performs several interconnected roles:

Connector: Establishing relationships between people who need to collaborate.

Translator: Helping different functions understand one another's priorities, language and constraints.

Integrator: Bringing together knowledge and resources to develop workable solutions.

Facilitator: Supporting alignment and progress across organisational boundaries.

Value creator: Helping both organisations translate commercial commitments into successful outcomes.

These are practical descriptions of boundary-spanning behaviour, not a new psychometric classification of salespeople. The distinction matters.

A salesperson does not become successful merely by possessing a particular personality or being naturally good at networking. Boundary spanning requires commercial judgement, organisational understanding, credibility and the ability to coordinate action.

Why this changes how we should lead sales organisations

If we accept that the salesperson is a boundary spanner, we also need to reconsider how we design and manage commercial organisations.

Traditional sales management often concentrates heavily on individual activity, pipeline progression and revenue generation. These measures remain relevant, but they do not fully capture the work required to develop and deliver complex B2B solutions.

Leadership should also examine whether salespeople are creating the right organisational connections. Are relevant customer stakeholders involved early enough? Do salespeople have access to internal expertise? Are delivery teams engaged before significant commitments are made? Does the organisation reward collaboration, or does it unintentionally encourage salespeople to protect relationships and operate independently?

These are not questions that can be answered by evaluating the salesperson alone. They concern the interaction between strategy, people and execution.

Five practical leadership questions

Customer understanding: Do our salespeople have relationships with the stakeholders who influence both the purchase and the success of the delivery?

Internal connectivity: Can they access and mobilise the knowledge and resources needed to develop the right solution?

Cross-functional collaboration: Do sales, delivery and specialist functions work together early enough in the commercial process?

Shared accountability: Are we aligned on what constitutes a successful customer outcome, beyond simply signing the contract?

Leadership and incentives: Does our commercial operating model encourage the creation of effective networks across organisational boundaries?

The answers may reveal that the greatest opportunity is not to increase sales activity but to improve how the organisation collaborates.

From winning the deal to enabling customer success

Within the Bridge Framework, developing stronger boundary-spanning capabilities should follow a deliberate sequence.

Clarify: Define the customer outcomes and commercial ambition the organisation is trying to achieve.

Diagnose: Understand the relationships, capabilities and organisational dependencies required to deliver those outcomes.

Design: Establish the roles, interfaces and collaboration practices needed across sales, customer stakeholders and internal delivery teams.

Activate: Develop networking, coordination and stakeholder-management capabilities through leadership, coaching and practical application.

Evolve: Learn from completed deliveries and strengthen the networks that contribute to sustainable customer value.

This reflects the broader relationship between Strategy × People × Execution. Strategy establishes what the organisation wants to achieve. People provide the relationships, expertise and capabilities. Execution turns those resources into results. The boundary-spanning salesperson helps connect all three.

The real measure of a successful B2B salesperson

The purpose of sales is not simply to transfer a contract from one organisation to another. It is to create a commercially valuable relationship in which customer needs can be understood, appropriate solutions developed and promised outcomes delivered.

In complex B2B environments, this cannot be accomplished by the salesperson acting alone. It requires a network of people working across organisational boundaries. The salesperson's role is to build, understand and activate that network.

This changes the definition of commercial success. Instead of asking only whether a salesperson can win the deal, we should also ask whether they can connect the people and capabilities required to make the deal successful.

The best B2B salespeople do not simply build relationships to sell more. They build networks that enable both organisations to perform better.
