[Coco] Inventory management or invoicing programs?

[Dezorian]

Hi all!

Anyone know of any inventory management, customer database, or invoicing 
programs for the Coco (or the TRS-80 Model 4P, for that matter)??

I'm looking to start a sort of "side business" and want to get my old hardware 
into the act.  Seems like it'd be much more fun than using a generic PC...

Any help would be greatly appreciated.

Thanks!
