If you’ve been thinking about monetizing your audience and selling online, then you must be wondering:

How to choose a custom product that is evergreen, easy to sell, and profitable? 

A quick Google search will probably take you down a rabbit hole of endless articles, adding to the confusion. 

But, here’s the goods news: 

Everything you need to know about how to create and design customizable products is right here in this blog post. And, in the era of custom merch and print on demand, this couldn’t be a better time to offer products online.

So, if you’re a creator or influencer looking to build a passive income stream, then keep on reading. As a bonus, you’ll also get a list of eight different best-selling items in 2024!

What are custom products?

A custom product is any type of digital or physical product that you can create and sell to customers online.

In recent years, print-on-demand (POD) products have become one of the top custom products to sell. Now, most creators and influencers will make branded merch such as face masks, mugs, throw pillows, and more.

The rise of branded merch is also evident by the sheer volume of #merchandise posts on Instagram.

Is selling custom products online a good business?

The short answer is—yes, it absolutely can be!

There are plenty of advantages to selling custom products:

  • More engagement and web traffic—selling products will create buzz around your business and drive traffic to your website.
  • A sense of community and belonging—customers who order your products will feel more connected with you and your brand.
  • Better social media exposure—launching your own custom products will increase brand awareness and recognition.
  • A new way for fans to support you—most customers are more than willing to support their favorite creator by purchasing their products.
  • Generate passive income—selling custom products such as print-on-demand merch is a low-risk way to monetize your target audience.

Plus, you don’t need a large audience to make a profit—according to behavioral economics, profit depends entirely on getting to the heart of your customer. So, as long as you have customers who love you and your content, your chances of making a profit are pretty much guaranteed.

So, how do you get started? There are several ways to create and sell products online, but most creators prefer starting a print-on-demand business for its cost-effectiveness.

Here’s why print-on-demand is the best way to sell custom products:

  • No start-up costs—you don’t have to financially invest in product manufacturing.
  • No logistical issues—order fulfillment, printing, and shipping are handled by the POD partner. 
  • No minimums—you can sell an unlimited amount of POD products to any market or audience.

Since you won’t need to hold physical inventory, your only potential expenses will be graphic design services (unless you’re an artist) or eCommerce platform fees. However, you can always add your expenses to the product price!

Designing products is easier than you think

Product design can literally make or break your sales. But, it doesn’t have to be hard or expensive. In fact, it’s easier than you’d think—you don’t even need to have design skills because there are numerous online resources and tools that you can experiment with. So, let’s dig in.

10 best graphic design resources for custom products

To get the perfect design, you can use royalty-free graphic resources, free programs and design tools, or hire a graphic designer. 

Here’s a list of the best graphic design resources:

  • Vexels—vector graphics for t-shirts and other types of customized products.
  • Shutterstock—thousands of free high-quality photos and vectors.
  • Flaticon—1,720,000 icons in every category.
  • Freepik—similar to Flaticon, but requires a license for commercial selling.
  • Creative Market—a marketplace with over 880,000 pre-designed graphics.

In addition to these resources, Canva is another highly popular design tool. Not only is Canva free, but there’s also a separate section dedicated to t-shirt design with thousands of premade templates.

Then there are design programs like Adobe Photoshop and Illustrator. With these programs, you can use vector designs to create multi-dimensional illustrations, logos, or typography.

Alternatively, you can also use a cost-free and open-source tool like Inkspace, which has just as many features as Illustrator.

Not into playing around with design tools? Then let me introduce you to Clint English. This awesome Sellfy store sells high-quality graphic design resources for custom products—from text effects, fonts, and illustrations to textures and pre-made artwork.

Optional: hire a freelance graphic designer

If you have the budget, you can also hire a freelance graphic designer to design products. While you probably won’t need a designer to create something as simple as an image with a catchphrase, you may need extra help for unique designs that require more complexity.

Here’s a list of the best websites for finding a freelance graphic designer:

  • 99designs—the go-to graphic design service where you can launch a t-shirt design contest to find your perfect design match.
  • Upwork—the biggest freelance marketplace for finding outstanding talent.
  • Fiverr—a beginner’s space where some artists list their skills for as little as $5.
  • Dribble—a great platform with established designers for hire.

8 best-selling custom products

To help you pick a product to sell online, I’ve put together a list of eight best-selling custom products with Sellfy store examples. 

You can use this as a source of inspiration, or put your own unique spin on a product to sell. Regardless of what you’re selling, remember that the key is to always provide value to your customers.

Custom apparel (t-shirts, sweatshirts & hoodies)

Here’s why you should sell apparel such as t-shirts: 

In 2023, the worldwide custom t-shirt printing market was worth $4,314.0 million. It’s predicted to grow steadily at a rate of 11.1% each year from 2024 to 2030.

So, a shirt with a trendy design is a perfect example of a high-demand custom product to sell online.

Aside from t-shirts, oversized unisex sweatshirts and hoodies are also among some of the best-selling custom items. In fact, unisex clothing is projected to grow by $65.6 billion over the next year. So, launching a line of trendy hoodies or sweatshirts is an absolute must for a custom products store in 2024!

Custom accessories (tote bags, phone cases & stickers)

A tote bag is also one of the best products to sell in your online store. Forbes has even called it the new must-have luxury item

But, will people buy it from you? In a 2023 survey, 27% of respondents said that they tried out a new product for sustainability reasons and 25% spent more money on sustainable fashion items.

Luckily for you, you can sell organic tote bags with Sellfy—they’re perfectly versatile and eco-friendly, and anybody can use them as reusable shopping bags, or street fashion accessories.

Another highly profitable custom product is the phone case. Literally, everybody has a smartphone these days—there are about 8.7 billion mobile connections on the planet

And, phone case sales are projected to grow 7.5% until 2025, reaching $35.5 billion. So, according to these numbers, you’ll definitely have potential customers if you decide to add phone cases to your selection of accessories.

You know what else you can sell? Stickers. Smaller items like stickers are much cheaper than other accessories, which automatically makes them a great option for customers on a tight budget. Besides, stickers used by your customers can help spread the word and promote your business. It’s a win-win!

Custom home & living goods (mugs & wall art)

The best part about selling home decor is that it has zero seasonality, so you can easily sell home goods all year long. Why not take advantage of that and create products that can make everyone’s homes a little cozier? 

For example, in a survey done by the Heinz company, nearly 60% of people said they had an emotional attachment to their favorite mug. And, it is hardly surprising—there’s simply no better way to start a morning than drinking coffee out of your favorite mug. This is why a lot of Sellfy stores sell coffee mugs.

In addition to mugs, you could also sell wall art. Despite the overwhelming presence of digital art, posters and canvases are as popular as ever. Most people love decorating their walls with aesthetic pieces of printed art, so wall art is without a doubt another best-seller that you shouldn’t miss out on.
