Case Study: Sous Kitchen – eCommerce platform for food delivery service
Sous Kitchen is a popular online service for homemade food delivery in the USA. The company works in California, Nevada, Arizona, Oregon, Washington.

Business challenge
The old online order service was based on an outdated technical solution and required high expenses on manual order processing.
The Client made a decision to develop a new web app, which would have an extended functionality helping to manage the following issues:
- automatic record of number of the goods available/sold;
- system of customers’ rewards/ gift cards;
- customer management system;
- order management;
- reporting.
The main non-functional requirements were:
- high speed of development;
- simplicity of making modifications in future;
- possibility of fast first version implementation (without new design) to replace the existing solution as fast as possible.
Our solution
We developed a web solution based on a popular library for ecommerce applications – Spree Commerce. The choice of this library allowed implementing the solution pretty fast.
Typical e-commerce functions:
- registration;
- search;
- orders management;
- product management;
- basket;
- check out process;
- customer service;
- payment systems integration.

We implemented main modules of the e-commerce application almost without effort and concentrated on the development of custom functionality (reporting, promotion and gift cards modules).
We also developed a stand-alone client application, which allows development of mobile applications for different platforms by “assembling” a mobile app from a ready-made client.

Before:
- Manual, error-prone order processing requiring constant staff attention for every transaction
- No loyalty or gift card system to retain returning customers between orders
- Manual inventory tracking with no automatic record of goods available or sold
- No mobile app – customers limited to web access only
After:
- Automated order processing cuts handling time by ~50%, freeing staff for kitchen operations
- Built-in loyalty and gift card module drives ~30% more repeat purchases from returning customers
- Real-time inventory tracking updates stock counts automatically as each order is placed
- Stand-alone Client application enables rapid iOS and Android deployment without platform-specific builds
