"Project" function within Zoho Books vs Zoho Projects

"Project" function within Zoho Books vs Zoho Projects

Hello,

I have a small consulting business and recently subscribed to Zoho Books. I require some level of project management for my business. I am wondering if the "Project" functionality in Zoho Books would be sufficient for a small business, or if I should also subscribe to Zoho Projects.

1. What are the differences and similarities between "Project" functions in Zoho Books vs Zoho Projects?
2. Which option is better for a small consulting business?

By way of background:

1. I will likely have 4-5 different types of projects, and need to create checklists for each project, and be able to set different stages for each project. I would like to see the progression of each project through its stages, through to completion.

2. I will need to assign staff to projects.

3. I use Bigin to manage leads until they become clients; Bigin is currently integrated with Zoho Books, so that companies/contacts from Bigin get added to Zoho Books.

I would appreciate your input and advice on how best to proceed. Thank you.
