A lack of cutting edge has cost the Firhill side dear in the opening weeks of the SPFL Premiership campaign as a host of chances have been spurned and points passed up.
Summer signing John Baird has yet to find the net for the Jags while Kris Doolan has two top flight strikes to his name so far.
And boss Archibald is keen to see his stars chip in with goals right across the park.
He said: "At this stage last season, Stevie Lawless had scored four or five and Chris Erskine had scored four or five.
"We play a shape that allows a lot of players to play. When we are on the ball, we want them attacking. We have told them that and they know that.
"Plus, we have the full-backs up there as well. It is not about the one striker. People say if you play one striker it is negative but I see it as three up front.
"It served us well last year and it is serving us well this year because we are creating the chances. That is the frustrating thing.
"You can't say we are playing badly. We are not one of those teams where it is nicey-nicey and when it gets to the final third nothing happens. We are creating chances but we just aren't taking them."
Thistle head into Sunday's meeting with Inverness on the back of a frustrating 1-0 defeat at home to Hibs last time out.
A lack of goals has put pressure on the Jags rearguard not to concede and Archibald admits his side must tighten up at the back to ensure they get points on the board.
He said: "People ask me what the difference is between the Championship and the Premiership and the difference is that you get punished in the top flight. If teams get one chance, they score it. We have to keep clean sheets.
"The boys at the back are frustrated because it is something we were good at last year. We had a run of five-in-a-row at one point.
"It is something we are working on all the time. It is mostly concentration to be honest.
"People might have thought we wouldn't have had as much possession and as much of the game as we have.
"Concentration was something we were good at last year when we had a lot of possession in games.
"But you are getting punished for any slip-up. If you keep a clean sheet, at least you are coming away with a point."
