Do SAP, Oracle, or other established ERP providers offer a packaged solution for small to mid-sized manufacturing businesses?

There no ERP Package for Small Businesses SAP Business One is the lighter version for medium sized companies and subsidiaries of large companies , also  Oracle E-Business Suite

No ERP package  for small business from tier I and tier II ERP vendors. Some of them however have package for Mid soze companies like SAP have SAP Business One , Oracle E-Business Suite , MS Dynamic NAV etc

Yes for any kind of project in return you are buying their own program. 

Yes, Definitely many ERPs are doing such practice for SMEs

Of course, ERP system does not depend on how big the company is.

But the question is, is it worth it to use an ERP system for a small size company ? I don`t think so, because the data will be already controlled easily.

Yes, Most of ERP Providers offer packages for small to mid-sized companies.

Enterprise resource planning (ERP) is an enterprise information system designed to coordinate all the resources, information, and activities needed to complete business processes.

An ERP system is based on a common database and a modular software design. The modular software design should mean a business can select the modules they need.

Today, Many of ERP Providers Depending on their Experiences releases an Ready-Made Packages based on the organizations size (Small - Medium - Large) and the the type of business.

In the past, ERP systems were used in larger more industrial types of companies. Today, the use of ERP has changed. In fact, ERP systems are used in almost any type of organization (large or small).

Of course. you just need to identify what your company needs from an ERP, and contact a partner either for Oracle or SAP and ask them about the available packages and compare them to the needs of your company.

The Concept of ERP is introduced for the Enterprise based Organizations only that means the Organizations which are operating their Business widely. To answer your question, I would recommend for Small & Mid sized Business Transactions and Operations, Its preferred to choose Microsoft Dynamics. If the Organization is very wide and should be accessed by the Business Users in the different locations then it's advisable to choose Oracle or SAP based on the Budget and Business flexibility.
