Mail Merge into Contracts/Documents

Mail Merge into Contracts/Documents

I have a house painting business. I have designed an estimating program in Excel (though I would like to make a better one in Zoho Creator if that is possible), and I want to merge fields from this estimating form into 2 forms: a proposal/contract for the client and a work order for the crew. This way the notes that I take at the estimate stating the details of the job, the contract price, and obviously the prospect's name, address, etc. would be merged into fields in these documents, and therefore only be entered once, and consistent, verbatim, throughout all documents. Is this possible? If so, how? Do I need to create this in zoho creator or can I merge fields into a quote or what? I've looked into this a lot, but sometimes you just have to ask! Thanks.
