The 20-year-old has found the net nine times for the Seasiders this season, but he has yet to open his account at international level.
Ince has started each of England U21s' last five matches, and although he has impressed in his overall performances, Pearce feels he needs to improve his finishing.
"Tom is just short of a goal for us at the moment," said Pearce, whose side earned a comfortable 2-0 win over Northern Ireland at Bloomfield Road on Tuesday.
"He is a very intelligent player - his movement is clever, running in behind and coming into pockets of space, and he just needs to supplement that by showing us at international level the goalscoring record he has at club level.
"He is a good finisher at club level, and he just needs that ball to sit for him and then he can find the back of the net and off we go from there.
"It is probably the only criticism that Tom will have for himself at the moment - that he has not found the back of the net in the games he has played for us.
"But he has been outstanding for us. He has come on the scene this season and done extremely well."
