this might work....

In an “explanation”, I do not really see much need for creativity. IMO this is usually where the KISS doctrine applies (“Keep it simple, …”). An unpretentious explanation might read like one of the following:
Business(es) help(s) to help (literal translation, already suggested)
Businesses participate in charity
Businesses realize social responsibility

Or you may want to use “economy” which (as a more abstract term than business*es* as in your specific context) is generally more equivalent to “Wirtschaft”.

But if you really think there is a need for a more slogan-like rendering (which might result in a higher level of wide appeal) you may want to pick something along the lines of:
Business(es)/economy aid(s)
Business(es)/economy care(s)

If choosing to be explicative, more details on the specific campaign might also be relevant.

Sounds better than "to help" IMO

Doing business to help others..
