Do you mean full tool bag? There are tons of programs out there that offer similar services like Hootsuite vs Buffer vs Sprout Social vs everything else, etc. You have to pick which ones work for you. I personally use Hootsuite for my business because its simple, free and suits my needs.
Other programs I use that aren't often mentioned are:
Google For Business Apps and Illustrator.
These might seem like simple tools but I really like everything that comes with google apps like sheets, docs, custom email etc. And I also LOVE using illustrator. I wouldn't be able to create any graphics without it. I'm not even a designer and I think I can widdle together some pretty professional-looking graphics that play a MASSSIVE role in my branding, marketing etc.
I use Croudbooster. Because Crowdbooster focuses on gathering data from your Facebook and Twitter feeds. Other features include being able to analyze impressions, total reach, and engagement. This will allow you to modify and improve your strategy by knowing what is working and what is not.
