Yes, awk is a well thought out, compact, yet powerful language; although a script this long should usually not really be written on one line, this would normally be easier to read:
Code:
awk '
  {
    A[$1]
  }
  $2~/\./ && sub(/\$/,x,$2){
    A[$1]+=($3=="paid"?$2:-$2)
  }  
  END{
    for(i in A)printf "%s balance: $%.2f\n",i,A[i]
  }
' file1 file2
