Why did Bigbank decide to implement PDF Generator API?

“As a bank, we operate in a highly regulated environment with especially high attention to customer data protection. As an example, it was a requirement for us not to have the service process customer data outside of the European Economic Area, which the PDF Generator API was able to meet by setting up a dedicated deployment for us.”

The Strategic Decision

Should You Build or Buy Your PDF Generation Solution?

For many development teams, the initial impulse is to build. It seems straightforward enough: install a library, write some code, and generate a PDF. However, creating a truly robust, scalable, and secure document generation service is a project in itself, fraught with hidden complexities and long-term costs that can divert significant resources from your core business objectives. Before your team commits to building a solution from the ground up, it's crucial to look beyond the initial lines of code and consider the total cost of ownership (TCO) and the strategic implications of that choice.

  • Infrastructure & Scalability: The Performance Bottleneck

  • Ongoing Maintenance: The Never-Ending Task

  • Security & Compliance: The Non-Negotiable Requirement

Why Katana decided to buy instead of build?

“On a strategic level, we have decided to utilise best-in-class solutions already available on the market and utilise our resources only to integrate them into our everyday operations. That way, we can focus on our strengths and core business, which is, after all, production. As a service provider, we can offer our clients the best possible solutions tailored to their needs. Whenever a client uses an integration we offer, they can be assured that it has undergone a rigorous validation process, and we are putting our seal of approval on it. No sub-par integration will pass through.”
