The best thing about telecombi is that it has a very user-friendly interface which makes it easy to use even for a novice like me! It also has a great support team who always help out with any queries I have. The only thing I dislike about this software is that sometimes when you try to add more than one account at once, it crashes. But other than that, everything else works perfectly fine. If your looking for an all in one package which can handle multiple accounts of different brands then telecombi should be your first choice. I am solving my business problems using telecombi. It's really helping me to manage and monitor all my telecom bills.
