A commercial agent is one of the oldest roles in the business world, and it still raises doubts when structuring a B2B sales team. Many founders and sales directors reach this decision without being clear on what it actually entails: whether it is a disguised employee, a self-employed professional with more freedom, or a completely different model of selling.

This confusion comes at a cost. Hiring a commercial agent without understanding their functions, legal framework, and boundaries usually leads to misaligned expectations, both for the company and the agent themselves.

In this guide, we explain what a commercial agent is, what functions they perform, how they differ from an internal salesperson, and when this model makes sense for a B2B company. Based on the experience of SalesDose structuring sales teams for B2B companies in Spain, the UK, and the USA.

What is a commercial agent

A commercial agent is an independent professional who sells a company's products or services in exchange for a commission, without being part of its payroll. They do not have an employment contract with the company they represent: they work as self-employed or through their own structure, and their income depends directly on the results they achieve.

In the B2B context, this role is primarily used to enter new markets, expand geographic areas, or cover sectors where the company does not yet have its own business relationships. The commercial agent provides their portfolio of contacts and local knowledge; the company provides the product, price, and terms of sale.

In Spain, the relationship between a commercial agent and the company they represent is regulated by Law 12/1992, on the Agency Contract. This law defines the minimum notice period to terminate the contract, the agent's right to goodwill compensation in certain cases, and the conditions under which exclusivity may or may not be agreed upon.

Unlike an employee, the commercial agent assumes the risk of not selling: if they do not generate results, they do not get paid, unless some type of guaranteed minimum has been agreed. This makes the model a low economic risk option for the company, although it is not free of other risks, such as relying on a single person to represent the brand in an entire territory.

Functions of a B2B commercial agent

The functions of a commercial agent typically include:

• Prospecting and acquisition. Identifies and contacts potential clients within the assigned sector or territory.

• Commercial negotiation. Presents the product or service, handles objections, and negotiates terms within the margins authorized by the company.

• Sales closing. In many cases, manages the order or contract until its final signing.

• Account follow-up. Maintains the relationship with the client after the sale, especially if working on commission for recurring sales.

• Market intelligence. Provides information on competition, pricing, and sector needs, being in direct contact on the ground.

These functions of a commercial agent vary significantly by sector: in industrial sectors, they usually focus on face-to-face visits and long-term relationships with a few high-value clients; in professional services, they focus on active prospecting, value propositions, and shorter sales cycles.

It is worth clarifying that the functions of a commercial agent do not include, unless expressly agreed, internal management tasks such as invoicing, technical post-sales service, or product support. When a company expects broader functions, such as implementation or customer success, it is best to put it in writing from the start to avoid conflicting expectations.

Commercial agent vs. internal salesperson: key differences

The most common comparison when structuring a sales team is between a commercial agent and an internal salesperson (salaried employee). The most important differences are:

• Relationship. The commercial agent is self-employed; the internal salesperson has an employment contract.

• Cost. The agent earns on commission (variable cost); the internal salesperson has a fixed salary (fixed cost).

• Control. The internal salesperson follows internal guidelines and processes more closely; the agent operates with more autonomy.

• Onboarding. The commercial agent usually starts faster by bringing their own portfolio of contacts.

• Dedication. The internal salesperson works exclusively for the company; the agent can represent several brands at once.

Advantages and disadvantages of the model

Like any sales model, working with a commercial agent brings clear benefits as well as trade-offs that should be understood before signing any agreement.

Advantages of working with a commercial agent

• Variable cost, not fixed: payment is based on results.

• Fast entry into new markets or territories.

• Access to an already built contact portfolio.

• Lower risk if the market does not respond as expected.

This last point is usually the most decisive for companies testing a market for the first time: instead of investing in a full internal team without knowing if the product will work there, the commercial agent model allows testing with a much lower financial commitment.

Disadvantages to consider

• Less control over the sales pitch and customer experience.

• Dependence on the individual motivation of the agent.

• Difficulty in scaling the model to many markets simultaneously.

The challenge of individual dependence is exacerbated when the commercial agent represents multiple brands at the same time: their attention and time are divided, and there is no guarantee that your company will receive priority over other brands in their portfolio.

Many B2B companies solve this balance by combining tactical commercial agents with an internal team that retains control of the process. If you want that control without losing speed, at SalesDose we structure customer acquisition teams that function as a direct extension of your company, not as an isolated external agent.

When it makes sense and when it does not for a B2B company

Understanding what a commercial agent is and what functions they perform is only half the decision. The other half is knowing if your company is at the right stage for this model. Hiring a commercial agent typically makes sense when:

• The company wants to test a new market without assuming fixed costs.

• The sales cycle is relatively simple and does not require extensive technical support.

• An agent with a relevant portfolio already exists in that sector.

• The available budget for sales development is limited in the initial phase.

Conversely, it is usually not the best option when:

• The sales process is complex and requires constant follow-up from the internal team.

• The company relies on a highly controlled customer experience from the first touchpoint.

• The goal is to build a long-term commercial relationship, not just close a one-off sale.

• The product requires a steep technical learning curve that an external agent can hardly sustain without constant training.

A practical way to decide is to ask what would happen if the commercial agent stopped working with the company tomorrow: if the answer is that all relationships with those clients would be lost, the model is probably creating more dependency than is healthy.

Types of commercial agents

Once it is clear what a commercial agent is, it is useful to differentiate between the existing types, as not all operate in the same way or fit every company.

• Exclusive commercial agent. Works only for one company within their territory, in exchange for a normally higher commission that offsets the exclusivity.

• Multi-portfolio commercial agent. Represents several non-competing brands or companies at the same time, dividing their time among all of them.

• Sector-specific commercial agent. Specialized in a specific sector (industrial, technology, services), providing technical knowledge and high-quality contacts within that niche.

• Geographical commercial agent. Covers a specific region or country, useful when international expansion is the main goal.

Choosing among these types of commercial agents depends on the objective: if total dedication is required, exclusivity usually offsets the higher cost; if the goal is just to test the waters with low commitment, a multi-portfolio agent may be enough to start.

SalesDose: how we structure the sales team

The question that really matters is not "external agent or internal salesperson", but how much it is costing you not to have that answer clear yet. Every month a B2B company postpones this decision, they continue selling with their current model, whether or not it is correct for their current stage.

At SalesDose we first design the customer acquisition process that your company needs, and only then do we decide if a commercial agent, an internal team, or a combination of both is the missing piece. We do this backed by sales consulting to diagnose your actual sales cycle, and automation so that this model does not depend on the motivation of a single person the day they decide to leave.

Frequently asked questions about commercial agents

These are the most common doubts that arise before deciding if hiring a commercial agent makes sense for your company.

How much does a commercial agent earn?

They normally earn on commission from closed sales, with percentages varying by sector, average contract value, and whether they have exclusivity with the company. In B2B sectors with high contract values, it is common to see commissions between 5% and 15% of the sales value, although there may be guaranteed minimums during the first few months.

Does a commercial agent need a contract?

Yes. In Spain, this is regulated by Law 12/1992 of the Agency Contract, which establishes the minimum conditions of the relationship between the commercial agent and the company they represent, including notice periods and potential goodwill compensation upon termination of the relationship.

Can a commercial agent work for multiple companies?

Yes, unless the contract specifies exclusivity. A multi-portfolio commercial agent represents several non-competing brands at the same time, allowing them to diversify their income but also dividing their attention among multiple clients.

What is the difference between a commercial agent and a distributor?

The commercial agent sells on behalf of the company and earns a commission on that sale; the distributor buys the product on their own account, assumes the inventory, and resells it to obtain a margin, not a commission. These are models with completely different risks and income structures.

Is it profitable to hire a B2B commercial agent?

It depends on the sector and the sales cycle. Now that you know what a commercial agent is and how their compensation is structured: for new markets and simple sales cycles, it is usually profitable because it reduces upfront risk; for complex B2B sales involving multiple stakeholders and long decision processes, an internal team or a specialized external SDR usually provides better control of the outcome and the entire process.

The decision between a commercial agent and an internal team is not made once and for all: it changes as your company grows. What remains constant is the need to have clarity about the model you are using today.
