Once again, we have a request for a cross tab report. If you search under that phrase, you can find a number of different methods for producing that type of report. If you read one and don't like the options, keep searching given the different methods available.
Alternatively and much more simply, you could produce a summary report that looks like this:
ACME Manufaturing $250
Spacely Sprockets $100
Mels Diner $25
Mels Diner $75
ACME Manufacturing $75
The above report uses summary fields, sub summary parts and sorting to produce this result.
