How to hire Amazon MWS developers

Amazon MWS lets you build apps for your own Amazon seller account and programmatically manage your inventory, orders, reports, and more. If you’re looking for a contractor who can help you unlock the potential of the data available in your Amazon seller account, an Amazon MWS developer can help. 

So how do you hire Amazon MWS developers? What follows are some tips for finding top Amazon MWS developers on Upwork. 

How to shortlist Amazon MWS professionals

As you’re browsing available Amazon MWS consultants, it can be helpful to develop a shortlist of the contractors you may want to interview. You can screen profiles on criteria such as:

  • Industry fit. You want an Amazon MWS developer who understands your industry so they can help you figure out how best to reach your target market. 
  • Project experience. Amazon is a big platform; screen for candidates who are experienced with the specific tools (e.g., Amazon PPC) you want to use.

Frequently asked questions

What is Amazon MWS? 

Amazon MWS is short for Amazon Marketplace Web Service. It’s an integrated API (application programming interface) that can be used for data analytics, app development, and sales automation. 

Here’s a quick overview of the skills you should look for in Amazon MWS consultants:

  • Amazon MWS
  • Web development
  • Marketing and sales automation
  • Familiarity with other Amazon products and services (e.g., AWS, Amazon PPC, Amazon FBA) 
  • Preferably familiar with product promotion

Why hire Amazon MWS developers?

The trick to finding top Amazon MWS developers is to identify your needs. Do you need help creating inbound shipments for a Fulfillment by Amazon (FBA) account? Or is your goal to develop an app that leverages data feeds from Amazon MWS APIs? The cost of your project will depend largely on your scope of work and the specific skills needed to bring your project to life. 

How much does it cost to hire an Amazon MWS developer?

Rates can vary due to many factors, including expertise and experience, location, and market conditions.

  • An experienced Amazon MWS developer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
  • A contractor who is still in the process of building a client base may price their Amazon MWS services more competitively. 

Which one is right for you will depend on the specifics of your project.
