Yeah, sometimes it takes careful planning to figure out tricks like that when corners and small spaces are involved. I know some work-arounds that I've done before, but being a visual person, if you post a photo of your bag-in-progress or an image of what the final product will look like, then I could offer possible suggestions on how to tackle it.
I made a small zippered purse for my mother once (the kind of thing that could be a coin purse, a pencil pouch, or makeup bag), and I ended up French seaming and topstitching the entire thing. The pattern was basically a rectangle, though it sounds like the bag you're making is more of a three-dimensional box shape. (I'm pretty sure it would be possible to French seam that kind of bag too, but I'd have to physically handle it to wrap my head around it.)
