How Should Vending Machine Operators Choose a Second Product Category?

Once a vending machine starts generating steady sales, many operators face a new question:

Should you add another machine, or introduce a new product category at an existing location?

Both options can work. But they solve different problems.

Adding another machine usually means finding another location. Adding a second product category is about getting more value from a location you already have.

That is why the best second product is not necessarily the one that is trending right now.

A better question is:

What else do your existing customers need, and can you meet that need with another product or self-service solution?

This is also an important part of how KEMORE approaches self-service retail equipment. A machine is only part of the business. The location, customer profile, and actual use case matter just as much.

When Is It Time to Add a Second Product Category?

If your first vending machine has only recently been installed, there is usually no need to expand immediately.

Start by understanding the basics.

Which hours generate the most orders? Who is buying? Which products move quickly? Which products sit in the machine for weeks?

The answers do not need to come from complicated analytics. Even simple sales records can reveal useful patterns when you track them consistently.

Your Existing Location Has Stable Traffic

Once you understand the customer flow at a location, it becomes easier to spot new opportunities.

For example, customers may regularly ask whether you sell phone accessories.

Or perhaps your location attracts a large number of young consumers, while the existing vending machine only offers standard products.

These are useful signals.

Your Existing Products Do Not Cover Every Need

The purpose of a second product category is not simply to put more products into the same space.

It should fill a gap.

For example:

Snacks and drinks meet immediate refreshment needs.
Phone screen protectors address an immediate service need.
Customized phone cases offer a personalized product experience.

Different products can serve different needs within the same location.

Your Current Operation Is Already Under Control

Adding a new category can also mean additional inventory, replenishment, maintenance, and customer service.

If the first machine still has frequent stockouts or maintenance issues, it may be better to improve the existing operation before expanding.

How Do You Choose a Second Product Category?

Do not start with the question:

“Which product has the highest profit margin?”

Look at the bigger picture first.

Factor	Question to Ask
Customer fit	Will existing customers actually buy it?
Location fit	Does it make sense in this environment?
Price	Is the price acceptable to the target customer?
Margin	What remains after all operating costs?
Operations	Is it easy to restock, maintain, and support?

Customer fit and location fit should come first.

A product can look attractive on paper and still perform poorly if it has little connection with the people visiting your location.

That is why product selection should start with the location, rather than the product itself.

Look for Products That Complement Your Existing Business

If you already operate a vending machine, you have an advantage that a new business does not:

You already have access to customers.

Instead of building an entirely new customer base, look for products that are related to the needs you already serve.

Existing Business	Potential Second Category
Snacks and beverages	Phone accessories
Phone cases	Phone screen protectors
Phone cases	DIY customization
Arcade products	Badges and collectibles
Tourist products	Customized phone cases and souvenirs
Campus vending	Phone accessories and daily essentials

Take a university area as an example.

The customer base is already relatively young. If a vending machine has established traffic there, products such as phone accessories, screen protectors, or customized phone cases may be worth testing because they target a similar audience.

That does not mean they will automatically sell.

It simply means the customer fit is strong enough to justify a test.

Your Second Product Category Should Match the Location

One of the most important lessons in vending machine operations is that the same product can perform very differently in different locations.

A product that works in a shopping mall may not work in an office building.

Start with the customer and the reason they are visiting the location.

Location	Typical Customer Behavior	Categories to Consider
Shopping mall	Shopping, leisure, younger consumers	Phone accessories, DIY products, collectibles
Arcade	Entertainment and longer dwell time	Badges, collectibles, customized products
Tourist attraction	Impulse purchases and souvenirs	Phone cases, souvenirs
University area	Young and highly personalized consumption	Accessories, screen protectors, DIY cases
Office building	Convenience and frequent purchases	Office supplies, personal care
Gym	Fitness-focused consumption	Fitness accessories, beverages

The key is simple:

Look at the customer first, then choose the product.

Do not choose a product first and then try to find a location for it.

Your Second Category Does Not Have to Be Another Traditional Vending Product

If your current vending machine mainly sells snacks and beverages, your next category does not necessarily need to be another type of food.

Self-service retail is expanding into more experience-driven and personalized products.

Examples include:

Phone accessories
Phone screen protectors
Customized phone cases
Custom badges
Collectibles
Personalized souvenirs

The difference is that customers may not be buying only a standardized product.

Some products solve an immediate need. Others create a personalized experience.

That is one reason non-traditional self-service machines are appearing in places such as shopping malls, arcades, tourist attractions, and university areas.

Why Consider a Phone Case Printing Machine as a Second Category?

For operators looking beyond traditional vending products, custom phone case printing can be an interesting option for the right location.

KEXIAOZHAN's phone case self-printing machines are designed around a different customer experience from conventional product vending.

A traditional phone case purchase might look like this:

Choose a design → Pay → Take the product

A self-service printing experience can be:

Choose an image → Customize the design → Place the order → Print the case

The customer becomes part of the creation process.

Instead of buying a standard product, they receive a phone case with a design they selected or customized themselves.

This makes the concept particularly relevant to locations with younger consumers and enough dwell time for customers to interact with the machine.

Potential locations include:

Shopping malls, arcades, tourist attractions, university areas, and lifestyle retail spaces.

For an operator who already has access to these locations, a phone case printing machine can be tested as a second product category.

The value is not simply another SKU.

It can turn:

Product vending

into:

Product sales + personalization + self-service experience.

Of course, location still matters.

A young customer base does not automatically guarantee demand for customized phone cases. The real answer comes from testing actual customer behavior.

Start Small Before Making a Large Investment

When you are unsure about a new category, testing is usually more useful than making a large purchase immediately.

A simple approach is:

Choose one established location

↓

Introduce one new category

↓

Track sales and inventory

↓

Adjust products, pricing, and presentation

↓

Decide whether to expand

During the test, track a few practical numbers.

Metric	What It Tells You
Daily orders	Whether demand is consistent
Average order value	What customers are willing to spend
SKU sales	Which products actually attract buyers
Inventory turnover	Whether stock levels are appropriate
Stockouts	Whether demand may be underestimated
Service issues	How difficult the category is to operate

Do not look at sales alone.

If a product repeatedly sells out, its recorded sales may underestimate the actual demand.

Inventory availability can limit sales, so it is useful to look at sales, stock levels, and stockouts together.

Score Your Product Ideas Before Choosing One

If you are considering several categories, a simple scoring model can make the decision more objective.

Factor	Weight
Customer fit	30%
Location fit	25%
Profit potential	20%
Operational difficulty	15%
Supply stability	10%

Give each category a score from 1 to 5.

The goal is not to produce a perfect mathematical answer.

It is simply a way to compare different ideas using the same criteria.

A product that is popular in the market may score only 2 out of 5 at your location.

Another less fashionable product could score 4.

The second one may be the better business opportunity.

4 Common Mistakes When Choosing a Second Category

1. Copying Someone Else's Best-Selling Product

A product that works in a shopping mall may not work in an office building.

Products can be copied. Consumer behavior cannot.

2. Looking Only at Gross Margin

A high-margin product is not automatically a high-return product.

If it sells slowly, it can tie up inventory, space, and capital.

3. Buying Too Much Too Early

The first goal of a new category is to validate demand.

Test first.

Scale later.

4. Ignoring Operating Costs

When evaluating a new category, include more than the purchase price.

Consider:

Product cost + logistics + location fees + payment fees + replenishment + maintenance + after-sales service + inventory

Only after considering these costs can you get a clearer picture of the real economics.

How to Expand From One Category to Multiple Categories

If the second category performs well, resist the temptation to immediately roll it out everywhere.

Instead, look for several locations with similar customer profiles.

For example:

Test in Shopping Mall A

↓

Test in Similar Locations B and C

↓

Compare the Results

↓

Scale the Equipment

This gives you more than sales data from a single location.

You begin to understand a repeatable combination of:

Location + Customer + Product + Equipment + Operations

That combination is much more valuable than simply finding one “hot” product.

KEMORE: Building Self-Service Retail Around Different Consumer Needs

For operators looking to move beyond traditional vending categories, KEMORE provides a range of self-service equipment designed for different product and service scenarios.

Its product portfolio includes:

Phone Case Self-Printing Machines
DIY Phone Case Printing Machines
Phone Screen Protector Vending Machines
Phone Case Vending Machines
Badge Printing Machines
Desktop Multifunction UV Printers

These machines serve different use cases rather than following a one-size-fits-all model.

For example, a desktop multifunction UV printer can be used for personalized products such as phone cases, mirrors, fridge magnets, puzzles, commemorative coins, and other small items, depending on the applicable fixtures and production requirements.

This gives operators another way to think about product expansion.

Instead of asking:

“What other vending machine should I buy?”

Ask:

“What other customer need can this location serve?”

That shift can lead to more practical product decisions.

Conclusion: Find the Second Category in Your Existing Customer Base

Adding a second product category is a natural step once a vending operation becomes stable.

But you do not need to start by searching for the “most profitable product.”

Start with your own location.

Who is buying?

When are they buying?

What else might they need?

What needs are not being served by your current products?

Can a new product or self-service machine use the customer traffic you already have?

If the answers make sense, test the idea.

For operators with established locations, solutions such as phone case self-printing machines, DIY phone case printing machines, phone screen protector vending machines, phone case vending machines, badge printing machines, and desktop multifunction UV printers can provide different ways to expand beyond traditional vending.

The right equipment depends on the location and the customer.

In the end, choosing a second product category is less about chasing the latest trend and more about understanding one simple question:

What does your existing customer need next?
