What is the advantage of having a one-stop-shop partner?
One-stop shop is a company that offers many products or services to its customers. The whole business can be structured under one roof.
Easier communication
Having one contact partner for the whole project saves a lot of time and reduces the possibility of incorrect communication or delays in waiting for calls from different providers.
Budget benefits
If you work with 2 or 3 different providers, you will pay to manage each account. This can be minimized if you trust a company to build all the modules of your project.
Complete solution
Your overall goal is to find the right solution according to time and budget. Working with a partner like BEA Solutions means that you will be able to combine every part of your business into one complete software product.
