The very fact that a quotation is being requested suggests that this is a compensation event (or why ask for a quotation). That is why using one of these on line administration tools (e.g. FastDraft) for managing NEC contracts is so good as it forces you to follow the correct process. The only way to ask for a quote through the system and in accordance with the contract is via clauses 61.1, 62.1 or 65.1. There should never be the need for a quotation directly off the back of an early warning.
As Dave suggests - follow the correct contractual process so you both know where you stand and everything is fully auditable.
