Success Story

Toki - Automating Invoice Generation

The Cloud Office team executed the project by adhering to established
practices. A thorough discovery process to gather biz and tech
requirements, followed by auditing the existing environment, proposing
an architecture, implemented the solution

The Challenge

TOKI, Bulgaria's first fully digital platform for providing electricity
services, needed to automate its invoice generation process, which
was not fault-tolerant, prone to errors, and involved a lot of manual

The Solution

To streamline the modernization of the data warehouse, a new
automated system was developed using serverless architecture. This
system encompassed project creation, API activation, cloud functions
for data handling, Apache Beam pipeline for data processing, and
Terraform/CircleCi for deployment and automation. The solution
leveraged Google BigQuery to streamline the data warehouse

The Result

The joint forces between Cloud Office and Toki's team delivered a fully
operational system for automatically generating monthly invoices,
automated and deployed in Google Cloud using Terraform and
CircleCi. The new system was fault-tolerant, eliminated manual errors,
and reduced the time spent on the invoicing process, enabling TOKI to
scale its operations and focus on its core business.



Cloud Office has been an exceptional partner,
providing seamless communication and outstanding
work quality. Together, we successfully built the
foundation of our data platform, transforming our
business operations. I highly recommend Cloud Office
for their expertise, dedication, and collaborative
