Estimate/Quote Module

I would like to propose to have the estimate/quote module. While many creative services are fixed prices, adding the estimate/quote feature would allow clients to submit a custom request that requires an estimate from the agency.

Once the estimate/quote is created, it should be sent to the client who requested it. The client should be able to accept or decline the estimate/quote as well.

If the estimate/quote is accepted, the request should be updated, and the estimate/quote should be converted to an invoice.
