At a consulting firm for Amazon FBA businesses, we have found that there is not step by step way or “cookie cutter” approach to build a business. Everyone has different limitations, capital constraints, time constraints and competitive advantages. At, we learn about you, your business, and your goals so we can gear our answers to your questions specifically for you. That being said, we do see similar questions. Here are the top 5 questions we receive along with their answers.

Do I need a custom package for selling on Amazon FBA?

No, you do not need a custom package to sell on Amazon FBA. The minimum viable package is a polybag because it entirely encloses your product at the cheapest cost. If you are just testing your product, to see if there is a market, go with just a polybag. However, having a custom package helps develop your brand and serves as a way to differentiate yourself from other products. You can use your package as a way to tell your brand’s story or share more information about the product.

Should I sell on other marketplaces besides Amazon?

Yes, you should exercise a multichannel selling strategy. By selling on multiple marketplaces you are taking advantage of having your product where your customers are. Some customers prefer the convenience of one-click purchases of Amazon, while another may prefer the bidding style of eBay. Whatever channel your customer prefers, your product will be listed on the site and be in front of the traffic of each of the different channels. If you utilize the Amazon FBA program, it easy easy to create a fulfillment order from your seller central dashboard.

What are UPC codes and how do they work with Amazon?

A UPC is a machine readable bar symbol with a readable 12 digit number. Each product has a unique UPC code. It allows businesses to track inventory and process orders at an increased rate. Every listing on Amazon has a unique UPC assigned to it. Amazon will automatically convert the UPC into their own internal SKU (stock keeping unit) system called an ASIN (Amazon Standard Identification Number). You will need a UPC for every unique product you sell. When creating a listing, it is entered in the last required blank on the first page. When you print the barcodes during the a shipping plan for sending products into Amazon FBA, your unique ASIN will be on the sheet to uniquely identify your product from someone else’s.

How much capital should I start with?

The answer to this question should be based off of the goals you are trying to accomplish. With greater capital, you are able to purchase more inventory, expand into more product lines, and have a greater marketing budget. You should develop a goal on the size of the business you are trying to build and and build a financial model based on the fixed and variable costs. As long as you have an understanding of your level of capable you are working with, you can build a successful business.
