Say it to an AI
Homepage hero for Billowby, invoicing for freelancers. Lead with the value proposition as a short, outcome-first headline about getting paid faster, then a one-line subhead that names the audience and the two proof points: 60-second invoices and automatic late-payment follow-ups. No buzzwords.
How an expert would brief the stronger version of “Invoicing app homepage hero”.

Why: The lines under the headlines give the same two specifics, '60 seconds' and automatic follow-ups, but only B's backs up a promise; under A's headline they read as a feature list.
