How to serve up slushies

How to Start a Slush Business in 7 Steps

In the 1950s, Omar Knedlik of Kansas City built the first slush machine from parts of a car's air conditioner.1 More than half a century later, slush drinks have become a classic treat worldwide, beloved for their refreshing chill and creative flavors.

Also known as slushies, slush drinks are frozen beverages composed of ice and sugary syrup and are often carbonated for a soda-like taste. While usually installed among candy bars and hot dogs in convenience stores and at gas stations, slush machines don't have to be a side offering; they can be the main event too. Slushie machines can be installed in virtually any operation, providing numerous possibilities for a slushie-based businesses.

In this guide, we will break down seven steps to starting a slushie business, including how to create a slush business plan, finding the right location, and buying slush equipment, so you can start serving up cold drinks in no time.

Step 1 - Determine Your Location and Research the Market

The first step to creating a successful slush business is determining your market. This largely depends on your location; ideally, you'll want to find a place with foot traffic, visibility, and accessibility. Additionally, you'll need to evaluate nearby competition and consider what will set your operation apart.

Unless you have a naturally large customer base, such as a gas station, customers usually won't go out of their way for a slushie. Location is paramount when it comes to generating the most business. Consider setting up in busy, high-traffic places like malls, downtown districts, or tourist attractions to maximize visibility. You could also start a catering business, serving slushies for events like kids' birthday parties, weddings, or concerts.

Serving slushies requires little equipment, so you won't need a large space to get started. A kiosk, food cart, or food truck should provide enough room to serve a complete slushie menu.

As you evaluate your surroundings, consider your target market. Do you operate in a tourist location with lots of vacationing families? Are you located in a college town with young, adventurous students? Building a customer profile will help you in the future when it comes to developing a menu and marketing plan.

Before settling on a location, review all zoning laws, rental agreements, and utility access needed for a smooth startup.

Step 2 - Develop a Slush Business Plan

After determining where you want to start your business, you need to develop a cohesive business plan. You will use it as a brainstorming tool and roadmap to help you visualize what will set your business apart, how you'll operate it, and how to make it work financially.

Deciding on an overall concept is a key first step. Do you want to focus solely on slush drinks, or are you going to serve other frozen treats as well? Consider the overall experience for your customers. Do you want to serve exotic flavors, focus on natural ingredients, or offer alcohol-infused slushies?

After brainstorming a concept and menu style, research your startup costs to create a financial plan. Include projections such as:

  • Current assets and liabilities (the money you have and the money you owe)
  • Fixed costs (rent, insurance, staff wages, etc.)
  • Variable costs (utilities, supplies, ingredients)
  • Break-even analysis (how many slushies you need to sell before making a profit)
  • Expected sales
  • Price per product
  • Estimated profit

Compared to larger foodservice businesses, slush shops have relatively low startup and building costs, making it easier to turn a profit quickly. Below is a sample cost and revenue analysis to give you an idea of initial costs to expect when planning your own slushie business:


Item Startup Cost
Slushie machine(s) $2,000-$10,000
Ingredients $100-$500*
Disposables $100-$300*
Other equipment $1,000-$2,000
Staff wages $10-$15 per hour*
Rent about $1,000*
Utilities about $200*
Insurance $200-$500*
Initial startup plus first month's operation About $15,000

*Monthly cost

To get a true idea of your profit margins and break-even point, you'll need to calculate the cost per unit, which will largely depend on what kind of slushies you plan to serve and what ingredients you choose to use.2

Step 3 - Handle Legal Requirements

After completing the first two planning steps, it's time to take care of legal requirements that will officially establish your slush business. Start by choosing a business structure and registering your business. The most common structures include partnerships, limited liability companies, and sole proprietorships. Your structure decision largely affects how you will pay taxes, file paperwork, and your level of liability.3

You'll need to acquire an Employer Identification Number (EIN), if you plan to hire employees, and a state health or business permits required for a foodservice business. Establish and follow best practices for food safety in order to ensure you'll pass health inspections and avoid fines or closures.

Step 4 - Develop Your Slushie Menu

After you nail down the concept and business structure, you'll need to develop a slushie menu. This can be a time-intensive process, involving trial and error to find just the right taste, but it's worth getting right. Don't rush through it—enjoy the process. Experiment with unique or zany flavors that grab your taste buds, and come up with creative menu names.

You'll also want to find the right ingredients for your operation. This may mean sourcing fresh fruit, purchasing alcohol from a qualified provider, or stocking up on ready-to-use slushie mixes. You can find bulk quantities of slushie syrups and mixes at KaTom.com.

Step 5 - Select the Right Slushie Equipment

"Businesses need to consider volume, space, and energy efficiency when selecting a frozen drink machine to match their needs."
— Jeff Resnick, CEO at Spaceman, a company specializing in soft serve and frozen beverage equipment.

One of the central parts of your slushie business is the frozen drink machine. This essential piece of equipment determines how quickly and consistently your products can be served. You will probably want multiple machines to serve different flavors, but if you're short on space or cash, you can simply create a neutral slush base in a single machine and mix it with bottles of your own syrup, similar to pouring syrup over shaved ice.

When looking for slush machines, consider the following:

  • Volume Capacity – Low vs. high-output machines based on expected demand.
  • Energy Efficiency – Cost-saving features and sustainability considerations.
  • Machine Type – Gravity-fed vs. pressurized systems and how they impact texture, consistency, and cleaning ease.
  • Machine Rating – Only special types of machines can handle alcohol-based or dairy mixtures.
  • KaTom offers a slushie machine buyer's guide to help you make the right decision on your purchase.

If you want to create slush drinks from fresh ingredients, consider purchasing a juicer machine or commercial blender to create syrups. You can also purchase ice cream topping units to store additional toppings for your slush creations.

Step 6 - Market Your Slushie Business

When creating a marketing plan, pull inspiration from your business concept and plan to create a memorable brand identity. You'll need to develop a logo design and overall aesthetic of your store or stand. You can even customize your slushie machine's exterior. Consider colors, phrases, and graphics that contribute to the identity of your business. Many slushie shops rely on bright, summery colors, but that doesn't mean you have to do the same; find a unique angle and run with it.

You'll also want to invest in online marketing by creating social media posts and interacting with the local community to grow interest. Consider promoting community events and tastings to showcase your business. You can also create a loyalty program or sponsor local sports teams and clubs. It's worth the effort to help get your name out there.

A successful slush business doesn't just bring people through the door; to help retain your customers, you could offer seasonal specials, promotional deals, or loyalty programs.

Step 7 - Maintain Quality & Operations

The most important step to building customer loyalty is to create a quality product and consistently maintain that standard of excellence. Slush drinks require a precise ratio of syrup, ice, and water to create their unique texture. While you will encounter equipment breakdowns over time, regular maintenance and cleaning can delay having to replace your machines.

Follow these steps to ensure you have a clean machine:

  1. Empty the bowl of any product and rinse it with warm water.
  2. Remove the bowl and any attached tap devices.
  3. Remove the auger and all seals from the cooling tube.
  4. Wash all components in hot water with mild detergent.
  5. Wipe down all surfaces of the machine and wash the cooling tube.
  6. Replace the auger and seals, adding food-grade lubricant where the auger will contact the seals.
  7. Secure the bowl into place.

Refer to your owner's manual for any additional instructions. We recommend cleaning your slushie machine about once a week, depending on demand. Regularly clean the drip tray and outer surfaces as needed.

It's also important to ensure you maintain the proper mixture for your slushie machine.

From a scientific perspective, maintaining the correct sugar ratio in the slushie mix is key, because it lowers the freezing point, making the liquid freeze slower and retain the slush consistency that customers expect. "Over-freezing happens when the mix ratio isn’t correct or when the machine isn’t maintained properly. Regular checks help prevent this problem," Resnick said.

Maintaining the right ratio will also help prevent the machine from clogging or adding too much strain on the auger.

Avoid leaving your slushie machine on for too long and to replace worn-out gaskets and seals to prevent leaks. Also, ensure that the machine has enough breathing room on all sides, so it doesn't overheat.

Bringing Your Slush Business to Life

Slushie businesses take time and effort to start up, but they also provide a simple way to turn a profit while creating refreshing drinks.

If you want a better idea of what the business is like before starting your own, it may help to gain experience by working in the made-to-order drink business. Consider what makes other slush shops, cafes, or smoothie bars in the area successful.

Common Pitfalls to Avoid

  • Choosing the Wrong Location – Besides slushie mix, location is one of the most important ingredients for a successful slush business. If your location isn't visible, it will be difficult to grow sales organically.
  • Overlooking Hidden Costs – Always budget for unexpected expenses when you first start.
  • Offering Too Many Flavors – If your menu is overwhelming, customers may have difficulty choosing what they want. Make it easy for your customers to order from your menu. It will also help your employees serve faster if there are less drinks to learn.
  • Using the Wrong Equipment – Consider expected demand before purchasing your equipment, and keep in mind that making alcoholic or milk-based slushies require special models.

If you're considering opening your own slushie operation, make sure you find the right supplies and start brainstorming a concept and menu that will draw crowds. You may be on track to start the next slush trend.
