Billie, a German fintech startup, offers online invoice factoring services to its customers, helping them to advance payments for their outstanding invoices. As an intermediary in handling payments, the company faced the challenge of ensuring utmost reliability and security. Unlike its competitors who operate as subsidiaries of large, established firms, Billie operates independently and had to obtain its own operating license from the German financial authorities. The company needed to build a stable, scalable platform from scratch that could adapt to market conditions and gain the trust of their clients. The challenge was to create a platform that was not only secure but also capable of scaling quickly and efficiently.

Billie chose to build its solution on Google Cloud Platform. With the help of Google Cloud Platform's managed services and intuitive interfaces, Billie’s team of seven engineers were able to set up their solution in just five months. The company used Google Cloud Storage to run a daily one-way automatic synchronization with a data repository, ensuring that backups were constantly on-hand in the event of a cyberattack. Only designated team members could access the repository through their Google Workspace accounts. The company also used auto-scaling Compute Engine instances with Container Registry and easy synchronization of data through Cloud Pub/Sub to deliver a highly reliable, well-integrated system for handling constantly updated payment information. Furthermore, Billie used Google BigQuery to collate data from highly heterogeneous data sources to evaluate the efficiency of its digital and offline marketing. This helped the company identify potential clients for its services and produce targeted advertising.
