The west Londoners' passage to the Europa League second qualifying round seems virtually secure after Damien Duff, Danny Murphy and Andrew Johnson scored in a comfortable 3-0 win at Craven Cottage.
"The only disappointing thing that we only scored three goals but I will forgive them because they were a bit tired." Jol said.
"We have had a good week and trained hard.
"If I say (it is job done), you will tell everyone I said the job was done so I will say it's a good score."
Fulham will have to play a further 22 matches if they are to repeat their 2010 heroics, when they upset the odds to secure a place in the final against Atletico Madrid.
Thursday night's game against NSI marked the start of an 11-month season for Jol and his troops, which some fear could see them struggle in the Barclays Premier League.
Some have also questioned the logic in starting the competitive season so early but Jol took a philosophical view of it all.
"Yes (it is early) but on the other hand all the other teams will play their first friendly game soon," he said.
"You have to approach it as a serious game but if you play a friendly game you do that after six or seven days and that's exactly what we did so I don't think it has a big difference."
