The test for a tagline is simple. Can someone who's never heard of your company read it and tell you what you sell?
If they can't, it's not doing work. It might be doing something else. Setting a mood. Sounding confident. Filling space on a hero section.
But it's not helping a buyer understand what you do.
The best taglines I've seen in B2B are almost boring. They describe the category, name the buyer, or state the outcome. No metaphor. No wordplay. Just clarity.
"Accounting software for small businesses." You know exactly what it is and who it's for.
If your tagline needs an explanation, the tagline is the explanation.
