Database to document

PDF and Word Generator API

PDF and Word Generator API

Businesses create a variety of documents from their enterprise systems such as CRM, ERP, SCM etc. The most common approach for the development of document automation functionality is by coding for each document template inside the system. It makes the code less modular and inflexible. Moreover, every time a template changes, the associated code require modifications.

PDF generator API allows the document creation to happen outside of application's core functionality and it can be ported across other applications thus allowing you to create complex workflows. For mobile apps, document creation outside the device reduce performance overheads, saves battery life and improves scalability.

It allows your business users to use existing templates. They can create/edit templates in their favorite Word and PDF editors without seeking IT support. Using external API that addresses various special scenarios and complex templates saves a lot of time and effort.
