How Can I Start Selling Aftermarket Car Parts?

If you’re a small business owner planning on selling auto parts online, the automotive aftermarket is a good place to start. The aftermarket industry is expected to gross $1.4 trillion by 2024, according to Global Market Insights, Inc. As the secondary market for replacement parts for vehicles, the automotive aftermarket encompasses everything from headlights and batteries to navigation systems.

The demand for aftermarket car parts is high as OEM parts can be expensive and need to be bought at the dealership, limiting the places consumers can find them. And when it comes to upgrades, aftermarket auto parts businesses tend to offer a more extensive selection. Some car enthusiasts have also recognized how high-quality aftermarket parts are better than OEM thanks to aftermarket manufacturers who have reverse-engineered the parts to remove their weaknesses. Aftermarket parts are also more available and can be conveniently purchased on eCommerce websites.

In this guide, we will talk about how eCommerce business owners can start selling aftermarket car parts.

Maximize Profit by Defining Your Niche

The best way to maximize profits for this type of business is to know what specific auto parts and accessories you want to focus on. Focusing on a niche allows you to deliver better shopping experiences. You may have a target market in mind. For example, if you’re after the market of people that modify and upgrade their cars, you’ll want to focus on exterior and interior auto-upgrade parts and lighting.

If you’re targeting the market that buys aftermarket parts to replace a broken or worn auto part, it helps to conduct market research to know which vehicle parts are replaced the most. This list will likely include oil filters, windshield wiper blades, air filters, brake pads, batteries, headlight and taillight bulbs, and spark plugs. Other parts that need to be replaced because they deteriorate over time and with use are tires, spark plugs, belts, alternators, wheel cylinders, fuel, and water pumps, fuses, engine sensors, mufflers, shocks and struts, and clutches.

Setting Up Your Auto Parts Online Store

Not having an online presence would be a mistake as the online sales of auto parts and accessories continue to grow and are expected to be a $19 billion industry by 2022.

Starting an online auto parts business on eBay is easy. If you have a large inventory of aftermarket products, consider using eBay’s Seller Hub. On Seller Hub, you can create listings more quickly, thanks to tools that allow uploading.

When you create a parts and accessories listing, you can use eBay’s Parts Compatibility tool to add all the fitment data or years, makes, models, trims, and engines that your part fits. Compatibility is referred to in the automotive industry as “fitment.”

Car parts businesses that sell car parts online will find that complete and accurate fitment data is crucial to your growing business. Fitment data makes it easy for potential buyers to find the right parts for their vehicles. On the listing form, you can either enter compatible vehicles manually or products to sell with pre-filled compatibility. For products that already exist in eBay’s enormous catalog, most of the listing information will be pre-filled automatically with the product title, description, category, weight and dimensions, and parts fitment data.

To get approval, you either need to already be a Professional seller with an account in good standing or have an independent website that Amazon can review.

If your answer is yes to all the following questions, then you meet Amazon’s basic requirements to sell auto parts and accessories.
