I've been working on a business process integration between zCRM's via the Deals module and Zoho Books and was a bit disappointed that the zBooks documents created via entity triggers had virtually no information from the relevant deal included.

I would have been less disappointed (and wasted less time) if the documentation about entity triggers actually detailed exactly what was included in the resulting invoices/estimates, and where.

Even better would be a thorough implementation of the entity triggers that results in a usable quote or invoice in Zoho Books. Including nothing but the Deal name, the description field and the deal amount on a single line item is virtually useless for any business process based around using the books estimate in a meaningful fashion.

This part of the books/CRM integration desperately needs work -- most of a fairly complex estimate could be built from the data gathered in the deals module -- products added, various fields added in the deal to pass through to the header/body of the Books document, with the estimate or invoice to be finalized in the Books interface (and update the Deal amount, etc). Blueprints, etc, aren't able to interact with anything in an integrated module.

These aren't trivial features missing. This isn't integration, it's two separate products that share a contact list and use iframes to let you pull up information from the other product.
