The make and model of Peter's monitor changes between scenes.
When Peter goes to Joanna's new place of work she comes out wearing her red work shirt. In one shot (from behind Peter), Joanna is suddenly wearing a denim jacket instead of the red shirt.
When Lumbergh and Portwood are in the consulting office going over reviews, Portwood disappears out of the scene once Lumbergh starts to be questioned by the Bobs.
While Peter and Joanna are having lunch at Flingers, Peter has a glass of water in front of him where the level changes each time the camera goes back to him, though he never takes a sip.
When Peter goes in to get interviewed for the first time by the Bobs, there is no shade or blinds covering the office window. You can see the office through the glass. However, when you see Peter first go in, the window is not see-through and has a blind/shade covering it.
When Peter is signing his confession and enclosing the traveler's checks, at least two of the checks have the same number on the top right corner. Obviously different checks, even the same amount, would have a different check number.
In the beginning, when Peter enters his cubicle, he pushes a button on his computer monitor to turn it on. Shortly thereafter, Lumbergh comes to talk to him and you see that the computer is going through the boot process. However, the button would only have turned on the monitor. Most offices have the actual computer under the desk, to save space, and you would have to go underneath the desk to turn it on, a separate action.
When Peter gets a phone call about his missing cover letter. The Avaya 8410D has 7 ring tones, the one in the movie is not one of them.
When Peter shuts down his computer, it shares characteristics
with both Macintosh and DOS-based computers, including a hybrid Mac/Windows GUI, an A: drive and a C:\ prompt. The movie is set in a generic, universally-identifiable world, and the hybrid computer is clearly a carefully-planned gag based around that theme, rather than a goof.
When Peter takes down the banner that says "Is this Good for the Company?" Milton has to look across the office at Peter. In a previous scene following the introduction of the Bob consultants, Milton is shown directly under the banner. However, throughout the movie, Milton talks about the fact that his desk is constantly being moved around the office. There also might have been more than one such banner.
The mismatch between the words and the lips when the doctor has the heart attack isn't a goof. It was intentionally done to show that Peter was "in a trance" or was "under". Reality, as he knew, it had been changed.
The big settlement that Tom got from the drunk driver wouldn't have played out the way it did in the movie. This is because it actually would have been Tom's fault because he backed out in front of the drunk driver just before the collision. In addition, Tom is shown heavily drinking just before the incident, making it likely that he had a high blood alcohol level as well.
However, this story is being told second-hand by a character who is known for being dumb so he may have embellished the details or gotten his facts wrong.

"Lose" is spelled "Loose" on the "Loose one Turn" square of the Jump to Conclusions mat. However, it's only a prototype and this is a common misspelling.
At Bill's birthday party, the pieces of cake being cut in closeup shots are much larger than the ones being passed around.
When Lumbergh first talks to Peter about his TPS report, Peter has some sort of ear plug in his right ear. The next shot it's gone.
When Peter and Joanna are driving home from the barbecue, Joanna's hair changes from hanging over her ear to being neatly tucked behind - identical to the shots of them driving to the barbecue.
While Tom Smykowski is presenting his prototype of his "Jump to Conclusions" mat to Peter, the audio near the end of the voice line "What do you think? It's a prototype!" abruptly ends.
When Peter disassembles the doorknob to his office, a mark can clearly be seen on the floor when he stops next to the ladder.
Peter says he opened a credit union account to take all the "fractions of a penny" that garnered the $305,000 and change, so it would be easy to trace the account back to him, since he would have had to open the account with verifiable information.
Michael clearly indicates that he wrote a virus that will "rip off the company big time," but could not install it because, "I don't know that credit union software well enough." Yet, when Peter installs the virus, all he is doing is downloading the virus file from the floppy to the credit union computer at work, and certainly Michael could have handled that. Even Michael himself says, "All we have to do is load it into the credit union mainframe, and the computer will do the rest."
When Joanna and Peter are on their way to the party she doesn't wear a hat, wears in at the party, and then back in the car it is off.
