Amazon fulfillment centers are opening all over the world.

Today, over 79 percent of Amazon sellers use Fulfillment by Amazon (FBA) in an effort to optimize their supply chains, maximize customer satisfaction, and ultimately grow their revenues faster. Some 58 percent of the top 10,000 sellers in America tend to use it.

If you’re not familiar with FBA, here are the basics. You store products in Amazon’s fulfillment centers rather than warehousing your own inventory. When your customers place an order, Amazon staff picks the orders, packages them and ships them out for you. This also allows you to market your business to a wider geographical audience.

While FBA definitely takes a certain load of your shoulders, as an e-commerce business owner, you still face quite a bit of pressure–sourcing goods, negotiating with suppliers, catalogue management and so on. Have you thought, for example, about the following questions?

  • Is this business my legacy or my path to my legacy?
  • Should I grow this FBA business or move on to bigger things?
  • Does this business trigger my passions when it comes to the products offered or is it a product of my passion to create businesses?
  • Do I have another opportunity that is bigger than my current business?
  • Do I want to cash out and take a break for a while?

Giving honest answers to these questions may have lead you to the conclusion that you’d be better off selling your Amazon business. And it’s been a path for many entrepreneurs to make their millions.

If that’s the case, these four companies might be able to help you seal the deal:

1. Digital Exits

If you have a large FBA business, you might want to consider using Digital Exits to broker the sale of your FBA business. The company specializes in selling online businesses that have annual profits ranging from $100,000 to $3 million.

To put an even finer point on things, they focus on online businesses that deal in high end goods. They have the ability to curate potential buyers who have cash in hand, and are willing to make deals. Sophie Howard, who used the company’s services to sell her Amazon FBA business, says that “Literally the day we put it on the market we had a really good offer, seven figures…”

2. FoundersIB

Founders Investment Banking is focused on dealing with businesses with annual profits in excess of $3 million per year. Their services include an analysis of your FBA business today, and the development of a predictive analysis on potential for future growth. This data is then used to create a sales package that will be provided to potential buyers. FoundersIB handles all negotiations during the sales process.

High dollar transactions require special attention to detail. Just like they handle negotiations, the firm also takes care of due diligence. This is useful, because that’s something a layperson is rarely capable of handling.

3. TheFBA broker

TheFBA Broker is owned and operated by Coran Woodmass. He can help you to do several things. It can help you to determine the valuation of your Amazon business today and advise you on increasing that valuations in the nearest future.

It can also help you find a buyer who is in the ideal position to purchase your business. In most cases, Woodmass himself guides people through the experience, and only matches you with serious buyers who have the capital available to purchase your FBA business. If your business isn’t ready for sale,

TheFBA broker can also let you know that–and help you prepare your business for sale, (hopefully) making it more attractive to potential customers.

4. Empire Flippers

Empire Flippers is an online marketplace for selling small Amazon FBA businesses, including your Amazon FBA business. However, it would be a mistake to compare it to Ebay.

This is because the team at Empire Flippers participates in the process by helping with tasks such as valuation, advising sellers on the best steps to take to presenting their business to potential buyers, and creating a curated process that ensures that sellers don’t waste their time dealing with buyers who are just window shopping.

Inexperienced buyers will likely appreciate the fact that the company provides hands on assistance during every phases of the selling process. This includes the transfer process, which can be more complex than first time sellers predict.

If you’re ready to sell your Amazon FBA business, think about partnering with a broker–whether one of these four or another. Their experience, connections, and insights are sure to benefit you during the often complex process. Using a broker can help you get the best price possible for your company while also expediting the entire sales process.
