No. If you sign your quote before its expiration date (Within 30 days or longer if agreed prior), and if no additional requests or work was added to the quote after you signed it, the price on your quote is the final price. In this case any additional costs related to time added during the execution of the work will be covered by Calfeutrage Apex Inc.   If however, you request to add additional elements or work to the existing project, we will revise your quote or create an additional quote for the extra work needed, which will require your approval for any additional cost.
