As the largest online retailer in the world, Amazon is an obvious option for those chasing eCommerce profits. However, people who really want 
to turn a profit should consider investing in the following software options.
One popular form of software sellers use to increase their profits is Amazon inventory management. By using Amazon inventory management, sellers can increase the amount of products they sell, which obviously means greater profits. Amazon inventory management also makes it easier for them to get these products uploaded to the site, so money isn’t wasted by handling the process manually. At a certain point, just about every seller will need Amazon inventory management if they hope to successfully scale up.
Another piece of software a lot of Amazon sellers use actually directly helps with conversions. It’s listing software that allows you to change the specifics of inventory you’ve already uploaded onto the site. So you may use it to make a change in the quantity of a certain product. This software can update that for you. Perhaps someone has undercut you on the price. With listing software, you can return the favor in a heartbeat, meaning that next sale may still be yours.
This third option isn’t really a form of software, but it’s still a great service. Signing up for Fulfillment by Amazon may be one of the smartest things you do in your selling career. It essentially hands over the responsibility of fulfilling your orders to Amazon themselves.
The way it works is that you send your products directly to Amazon, who will house them in one of their fulfillment warehouses. When an order comes through, Amazon then handles shipping it out to your customer. Not only will this be way more convenient than keeping an ocean of inventory in your home, it can also help your rankings. As Amazon can physically confirm your inventory, they’ll be more comfortable giving you higher spots in Buy Boxes. Sellers who handle their own fulfillment could be wrong about the amount of product they have, leaving Amazon customers high and dry.
There are all kinds of other software out there that are worth considering too. The type that handles taxes is especially important. You’re an independent operator, so don’t expect Amazon to handle any tax information for you. Tax software won’t help your profits, but it could save you a lot of money.
Although this help will cost money, the software listed above could quickly cover your investment if used correctly and bring in impressive profits later on.
