Web application development with Joomla

Hello Forum, I was looking into different Web Application Frameworks and was wondering if Joomla is suitable to fall into that category. If a customer asks for a Web Application for customer and provider management, pro-forma generation, invoicing, and other related internal back office processes (mostly database related functions like Create, Update, Read and Delete entities) and also creating reports. It is reasonable to think in Joomla to develop an application like this? Any other more suitable Web Application Framework? Best regards, Tadeo
