Project Overview:

Our client is one of the leading meal kit companies. They're providing 111 million meals to 4.2 million households worldwide in 14 countries across 3 continents. From procurement tools to conversion rate optimization, live pricing tools, payment services and add-on upselling features, company works on a wide variety of challenging problems.

Now project is focused on creating internal tools for making supply chains more efficient and productive. There are some new incoming projects related to improving processes of comparing orders from the ordering tool (OT), goods received from the FCMS, and invoices from vendors.
