The Client is a European online marketplace with more than 2 million registered users.

challenge

For a long time, the Client used a billing-as-a-service (BaaS) solution for international payment processing. However, the company estimated the cost of continuous usage of the system to be much higher than the cost of the development and maintenance of an in-house solution.

Solution

It was decided to implement a custom billing solution. To smoothly substitute the previously used billing system, VolgoTechnologies team needed to understand the principles of its work. At the start of the project, our specialists gathered the information piece by piece collaborating closely with the Client developers who integrated the previous BaaS system, the Client employees (the Finance, Customer Support, and Security departments), the Client provider of the BaaS, banks, payment systems and debt collection agencies.

Initially, VolgoTechnologies team quickly got the general understanding of the solution functionality and connections to start implementation as soon as possible. The more detailed requirements and specifications continued to frame up in the course of agile iterations where business analysis took place in parallel with implementation.
