I was thinking of option B but option A seems to be better.

option A

maude Lachapelle and to all the other voters: are we talking here about being able to give options to choose from in the submission? So depending on his choice, will it be added or subtracted from the total of the tenders and then to the contract after signing?

For example: a basic quote for the repair of a roof at $12,000, with options that the customer can check himself:

☐ High-end membrane instead of the standard membrane (+ $1,500)

☐ Replacing gutters (+ $800)

☐ 10-year extended warranty (+ $450)

As the customer checks or unchecks, the total is automatically recalculated. Once he signs, this version (with the options selected) becomes the official contract.

Is that what you have in mind (OPTION A)

or

OPTION B: rather a question/answer form that's just used to give us information to build your own quote afterwards?
