What resources, tools, and applications do you use that have helped grow your small business?
There are so many tools out there designed for businesses that it can be overwhelming determining which are the best options and if they will actually save you time and help grow your business. For example, it can be a struggle figuring out if the benefit of an application designed for email marketing or data management will justify its cost. To that end, I think it would be extremely beneficial for the community to share the resources you all use that have actually helped grow your business (and maybe even those that haven't). Sometimes trial and error is not an option for a struggling business and a good recommendation can go a long way.
One cool tool I've found for curated lists of business resources is called postmake, but I'd love to hear what the rest of the small business community uses!
