Do not leave completing your tender to the last minute or return your tender after the date or time of closure as the deadline will have been missed.
Peidiwch â gadael y gwaith o gwblhau'ch tendr tan y funud olaf neu ddychwelyd eich tendr ar ôl y dyddiad neu'r amser cau gan y bydd y terfyn amser wedi mynd heibio.
