Big companies train their reps to squeeze every dollar out of you. BillSlayer listens to your calls and tells you exactly what to say to get the rates you deserve.
Your phone company says:
“That's the best rate we can offer.”
BillSlayer tells you to say:
“I have a quote from T-Mobile for $40 less. Can you match it?”
Customer service reps are trained to protect company profits, not save you money. They know exactly what to say to make you accept their “best offer.”
BillSlayer levels the playing field. Our AI listens to both sides of the call and feeds you the exact responses that work—based on data from thousands of successful negotiations.
No negotiation experience needed. We tell you what to say.
Phone, internet, insurance, medical bills—we'll show you competitor rates and how much you can realistically save.
Put your phone on speaker and tap “Start.” Our AI hears the conversation and shows you what to say next—silently, on your screen.
