Don't laugh until you try this...
Pee in a spray bottle, thoroughly rinsed first. Go "mark" your invisible fence. Then walk the dog along the line. Say no if it goes outside your marked territory, praise for staying inside.
Cost: water/tea/coffee/beer you drank. Not only serves as boundary for your dog, but is a no trespassing sign for other dogs & critters.
Smells, they get, better than we'll ever fully understand.
Seriously, stop laughing! Just try it!
