I'm a solution manager helping customers to develop financial processes.
I like SAP's premade workflows for various areas, such as supply chain, procurement, or finance.
The user interface could be improved. For example, sometimes you're missing some data and can't complete a task. There should be some built-in support and suggestions on how to solve your problem. I would also like the interface to be optimized to work better with mobile devices like tablets and smartphones.
It's not appropriate for smaller companies. For example, ECC 6.0 has a lot of modules that a small customer may not use.
SAP support is excellent. I've worked with them on many critical projects for large enterprises. SAP also has a strong network of partners who implement ERP for end customers.
SAP ERP is difficult to set up. You need to configure lots of things during the deployment. The deployment time depends on the company's size. It might take a couple of years to fully deploy SAP ERP for a multinational corporation.
You need to undergo the initial setup and a few testing rounds. Some companies can do it in a year, but large enterprises have multiple systems to integrate. Smaller companies can do it in under a year. It takes time to deploy it across several departments, such as finance, logistics, etc.
SAP ERP is expensive compared to competing products. The general feedback from customers is that most people say it's expensive.
I rate SAP ERP nine out of 10. I would recommend SAP depending on your budget and requirements. It's one of the best ERP solutions for large enterprises, but I would suggest something else for a small or medium-sized company.
