- Industry: eCommerce, inventory management
- Expertise: eCommerce development, SaaS, Amazon API integration
- Business goals: reduce client losses, prevent fee overcharges
- Applied technologies: Python/Django, MySQL, Redis, RabbitMQ, Docker, JQuery, Vue.js, NPM, Pandas
BUSINESS CHALLENGE
Before the project started, our client tried their best to manage the eCommerce business but issues with lost or missing inventory, return fees, and other general errors were a frequent problem. Although Amazon provides reimbursement services to sellers, there have been a lot of cases where a more thorough analysis needed to be conducted using various details.
Whether it is missing units, lost items, issues with inbound shipments, damaged items, customer returns that include items that cannot be sold anymore, or goods that were returned but have still not been added to the inventory by mistake, it can be hard to keep track of everything, especially when the clients already have a lot on their plate in terms of sales management.
So, our team needed to find a solution that would enable the client to keep up with all the processes related to reimbursement seamlessly with the help of automation and meticulous analysis of data.

PROJECT DESCRIPTION
In case you would like to calculate the numbers to get an overview of sold products, calculate the income and keep a track of money spent on Amazon advertising, our Advertising Reporting service can help you. Besides, our repricing system can set an automated process for changing prices of products when required.
PROJECT SUMMARY
- Location: Worldwide
- Team: Project manager, 3 developers
- Industry: eCommerce, Amazon Advertising
- Expertise: eCommerce development, Amazon API
- Business goals: Calculate costs, analyze the necessity for repricing, analyze income based on sales, setting of automatic repricing
- Applied technologies: Python, Django, Rabbit MQ, Angular, Advertising API
BUSINESS CHALLENGE
When our client started working with us, the main objective of the project was to see an overview of statistics on the client’s sales, to calculate income, and to conduct analysis. Pretty much the majority of these tasks are usually calculated manually, which does not make the process any easier but, quite the opposite, prolongs it and makes the client focus on routine things instead of the flow of business itself.
Another thing that mattered to our client was the option to clearly analyze and see the amount of money spent on advertising their products in the Amazon Advertising system.
Besides that, what is also important in Amazon sales is to know whether your product has a competitive price, as it should not be too far ahead or behind your competitors’ prices.
