How to cover the complete life cycle?

How to cover the complete life cycle?

Greetings, I hope find all well and safe!

I have many situations as described below and I would like to know what the most practical way to proceed into Zoho.

1. A client ask me for a list of products.
2. I do not have any product available, so I need to make quotations to may vendors, but I need to quote different items in different vendor to compose all items that my client has requested.
3. Once my different vendors got back to me I need to issue a single estimate to my client and answer to it.

So, I need to cover a complete life cycle. And from what Zoho can I cover all the steps without need switch between apps (we have all available from a Zoho One plan).

Need help, please.

Thanks in advance.
