Exploring the Spectrum of Selling Jobs: From Merchandisers to Intangible Product Sellers

Walk into any market in India, and you will witness a fascinating range of selling activities. A milkman delivering bottles at your doorstep, a shop assistant ringing up your purchase, a pharmaceutical representative explaining a new drug to a doctor, and a software professional pitching an enterprise solution to a CEO are all engaged in “selling.” Yet, the skills, creativity, and responsibilities each role demands are dramatically different. Understanding this spectrum is essential for any marketing manager who wants to build a sales team that actually works. Let us unpack the major categories of selling jobs and see how each fits into the larger commercial puzzle.

Why classifying selling jobs matters 🔗

Sales is not a single, uniform activity. The American industrial psychologist Robert N. McMurry was among the first to formalise this idea. His research, published in the early 1960s, argued that each type of sales work demands its own configuration of traits, attributes, and qualities. In other words, putting a creative, persuasive personality on a delivery route would waste their talent, and putting a quiet order-taker in a high-pressure intangible-product role would lead to burnout.

For managers, classifying selling jobs is not an academic exercise. It directly shapes recruitment, training, compensation, and territory design. A clearly defined sales role aligns the salesperson’s daily activities with company strategy and helps measure productivity in a meaningful way.

The merchandise deliverer 🔗

At the simplest end of the spectrum sits the merchandise deliverer. The primary job here is to deliver the product, not to persuade. Think of the milk vendor, the bread distributor, the gas cylinder delivery person, or the bottled-water supplier. The customer has already decided to buy; the salesperson simply ensures the product reaches them on time and in good condition.

Selling skill is minimal here, but reliability and pleasant service are everything. The fundamental purpose of any salesperson is to retain existing business and win new customers, and for the deliverer, retention depends almost entirely on consistency. A late delivery, a damaged carton, or a rude exchange can lose an account that took years to build. Repeat business comes from courteous behaviour and dependable service rather than persuasion.

Order-takers: inside and outside 🔗

The next layer up consists of order-takers, who collect orders without doing much active selling. There are two sub-types worth distinguishing.

The inside order-taker 🔗

The inside order-taker works behind a counter or at a phone or screen. The retail sales assistant at a department store, the telecaller at a tele-shopping centre, and the e-commerce customer support agent who confirms an order all fall into this category. The customer walks in or calls in already intending to buy. The role is largely transactional: take payment, hand over the goods, answer basic queries.

The outside order-taker 🔗

The outside order-taker travels to the customer rather than waiting for them. A representative from a soap or biscuit manufacturer who visits supermarkets and kirana stores to check stock and write fresh orders is a good example. The shop owner does not need to be convinced to buy soap; the soap is needed to run the store. The challenge for the outside order-taker is territory management, route planning, and ensuring competitors do not capture shelf space. As one classification notes, these salespeople primarily respond to customers’ requests rather than actively persuading them, and many are increasingly being replaced by efficient telemarketing teams.

The missionary salesperson 🔗

Now things get interesting. The missionary salesperson does not actually close any sales. Their job is to build goodwill and educate decision-makers who can later influence purchases. Missionary selling is a form of indirect selling where the salesperson focuses on building relationships with individuals who can influence buying decisions, rather than directly closing the sale.

The classic example is the medical representative who visits doctors. The doctor cannot purchase the drug from the rep; the patient buys it from a chemist. Yet without the rep convincing the doctor of the drug’s benefits, the prescription, and therefore the sale, never happens. A pharmaceutical representative might call on a physician to provide clinical information about a medication’s effectiveness, hoping the doctor will prescribe the drug. Similarly, textbook publishers send representatives to college faculty, hoping the professor will recommend a particular book to students.

In the tourism and hospitality world, the same model exists. Tourism board representatives visit travel agencies to educate agents about a new destination, knowing that an informed agent is far more likely to recommend that destination to future travellers. Hotel sales managers visit corporate HR teams to position their property as a preferred venue for offsites and conferences.

The sales engineer 🔗

As selling moves into more complex products, we meet the sales engineer, sometimes called a technical specialist. This is a hybrid role demanding both engineering knowledge and persuasion skills. A sales engineer is a sales professional responsible for selling complex, technological, and scientific products through a consultative sales process.

Sales engineers typically operate in B2B environments such as industrial machinery, chemicals, telecommunications equipment, medical devices, and enterprise software. They act as a bridge between a customer’s technical resources and their company’s sales team, typically working in industries like high-tech manufacturing, merchant wholesale, and computer systems design.

Imagine a company supplying conveyor systems to a coal mining operation. A generalist salesperson would struggle to discuss load-bearing capacity, motor efficiency, and safety compliance. A sales engineer can analyse the mine’s specific operating conditions and propose a customised solution. Here the “product” is not just the equipment; it is the technical expertise wrapped around it.

The tangible product seller 🔗

This is the role most people picture when they hear the word “salesperson.” A tangible product seller sells physical goods to customers who often did not know they needed the product until the salesperson showed up. Vacuum cleaners, encyclopaedias, water purifiers, kitchen appliances, and even cars sometimes fall into this bucket.

The job demands creativity, resilience, and the ability to handle rejection. Unlike order-takers, tangible product sellers must generate demand. They knock on cold doors, run live demonstrations in residential complexes, and turn casual curiosity into committed purchase. Companies like Eureka Forbes built entire empires in India on this direct-selling model. The salesperson must read the customer, identify a latent need, and demonstrate how the product solves it before the prospect loses interest.

The intangible product seller 🔗

At the highest end of the creativity spectrum sits the intangible product seller. Here the salesperson is selling something the customer cannot touch, see, or test before purchase: insurance policies, mutual funds, advertising space, consulting services, education, or holiday packages.

This role is psychologically demanding. The customer pays today for a benefit that may arrive years later, or in some cases, may never arrive in any visible form (think life insurance). Trust is the entire product. The salesperson must be a skilled storyteller, able to make abstract benefits feel concrete and immediate.

Tourism is a textbook example of intangible selling. A holiday package, a cruise booking, or a timeshare membership cannot be sampled. The traveller is essentially buying a promise of an experience. The salesperson must paint the picture so vividly that the customer can almost feel the sand between their toes before signing the cheque.

Why role definition is a management responsibility 🔗

Once you accept that these roles are genuinely different, several management decisions follow naturally.

Recruitment and selection 🔗

Different roles demand different personalities. A patient, methodical individual may excel as an outside order-taker servicing a steady route, while the same person might collapse under the pressure of selling intangibles. Conversely, a high-energy persuader hired for a milk-route delivery job will quickly grow bored and quit.

Training 🔗

Training programmes must match the role. Defined roles help managers design tailored training programmes that address the specific skills required for each position; a consultative salesperson may need advanced negotiation training while a sales engineer benefits more from technical training.

Compensation 🔗

Pay structures should reflect the kind of effort the role demands. Straight salary works well for missionary salespeople and delivery roles, where the link between effort and immediate sales is weak. Straight commission or aggressive incentive plans suit demand-creating roles where every closed deal can be tied directly to the salesperson’s effort. A combination of salary and commission often makes sense for sales engineers and tangible product sellers.

Performance evaluation 🔗

You cannot judge a missionary salesperson by the same yardstick as a tangible product seller. The missionary’s success may show up in prescription patterns or shelf placements months later, while the tangible seller’s success is measurable by the day. Mismatched metrics demoralise good people and reward the wrong behaviour.

The Indian context 🔗

India offers a particularly rich landscape for these classifications because the economy spans extremes. In any given week, the same company may need delivery boys for last-mile e-commerce, inside order-takers at a quick-commerce dark store, missionary salespeople calling on doctors, sales engineers pitching industrial automation to a factory in Pune, and intangible sellers persuading a young couple in Bengaluru to buy a unit-linked insurance plan.

The rise of digital tools has reshaped, but not eliminated, these roles. Inside order-takers now operate via WhatsApp and chat windows. Sales engineers conduct demonstrations over Zoom. Missionary salespeople in pharma supplement field visits with webinars. The fundamental categories remain, even as the channels evolve.

Bringing it all together 🔗

The genius of McMurry’s classification, refined later by writers such as McMurry and Arnold, was to remind managers that “salesperson” is an umbrella covering a forest of specialised trees. From the merchandise deliverer at one end to the intangible product seller at the other, each role demands a distinct mix of creativity, resilience, technical knowledge, and emotional intelligence.

For any marketing manager, the practical takeaway is simple: write clear job descriptions before writing job advertisements. Define what kind of selling the role actually requires, then build the recruitment, training, compensation, and evaluation systems around that definition. Skip this step, and you will be left with a sales team that is busy but unproductive, talented but misaligned, and expensive but ineffective.

What do you think? Looking at the Indian companies you interact with as a customer, can you identify which type of selling job each of their representatives is performing? And if you were building a sales team for a new tourism start-up offering experiential travel packages, which two or three roles from this spectrum would you prioritise hiring first?
