Mandatory upgrade prior to date?????

SO LET ME GET THIS STRAIGHT...IF A CLIENT IS WORKING ON SOMETHING THAT ONLY NEEDS 1 HOUR WORTH OF CREDITS TO COMPLETE, YOUR ALGORITHM BASED ON USAGE, OVERRIDES THEIR REQUEST AND BASED ON USAGE, I ASSUME GIVES A DATE OF WHEN THAT PACKAGE THEY ARE IN SHOULD LAST UNTIL? SINCE IT DIDN’T LAST IT ONLY.....ONLY OFFERS THEM THE UPGRADE FEATURE OR THEY ARE DONE USING YOUR SOFTWARE TIL THE PROJECT DATE LIKE A LITTLE CHILD ON PUNISHMENT??? UPGRADE OR SIT IN THE CORNER???
