We would like to segment retail/warranty and wholesale customers. The relationships, politics, payment terms, and internal training and responsibilities involved is different with both customer types. We currently use 2 Zoho invoice organizations to keep the 2 universes separate, but we would like everything in 1 accounting system. Another issue is reporting. Right now, I can see how many of what I sold to resellers, and how many of what we sold/served to retail customers. I would like to retain this ability, while using Books.
