Can the buyer alter/change the service request details after it’s submitted?

The service request (SR) can be cancelled by the buyer and then resubmitted if no bids were awarded.  Once SR is submitted it only can be altered by the person bidding to re-negotiate original contract. If the buyer needs to alter the details of the request after bid was accepted then simply have the seller resubmit the new agreement to the buyer for acceptance.  Buyer can cancel the request for help at any time but there will be a small fee (per terms and services agreement signed) if there was a communication to any of the sellers or if bid was accepted.
