When time is of the essence and you need to make a decision fast, you don’t have time to read. You just want your system to “show me the money!” Consider this:
You’re on the phone with a potential customer your team has been working for the last few weeks and their general attitude is “shut up and take my money!” You have all the information you need right in front of you. Now, all you need to know is if they qualify, but that requires reviewing a bunch of different fields, and every second you delay, your lead is growing more impatient. Your admin might have added a text formula field to tell you this, but you still have to sift through all the other nearly identical fields. All you want is a big thumbs-up so you can make the sale. Well, Salesforce can do that for you!
Salesforce formula fields are an invaluable tool for checking and validating information on a record, giving you dynamic feedback, and performing complex calculations instantly. But did you know that you can use a formula field to display an image? Simply use the IMAGE() tag for the formula’s output and you can show your team the lead they’re working is qualified with a big thumbs-up, warn them an account is overdue with a fat red X, flag a contact on their birthday, or show your customer support team exactly which cases came from Facebook, Twitter, Email, and the Web without cluttering their list views.
