The quotation is downstream of the declaration
Nothing in an insurance quotation is invented by the person quoting it. The figure is produced by applying rating to a risk as it has been described. Which means the quality of the description, not the skill of the negotiation, determines whether the quote survives contact with underwriting.
This is why the discipline in insurance quoting runs backwards compared with most industries. The effort belongs at the front, in capturing the schedule of assets or lives, the activity, the sums insured and their basis, the claims history and the features of the risk. A thorough declaration produces terms that hold. A thin one produces an attractive number that has to be corrected later, and the client experiences that correction as something done to them rather than as the natural consequence of an incomplete picture.
