Flat rates beat per-seat math
HubSpot Sales Hub is priced per seat, from Starter through Enterprise. Mercury plans are flat monthly rates with unlimited users on every tier, so adding people does not raise your bill.
Mercury vs HubSpot
HubSpot charges per seat and per onboarding. Mercury answers, dials, and books for a flat monthly rate with unlimited users.
Why Mercury
Why choose Mercury over HubSpot?
No onboarding fee
HubSpot's Professional and Enterprise hubs carry one-time onboarding fees of $1,500 to $7,000. Mercury has no setup fee on any plan.
AI voice that answers and calls
HubSpot's voice agent is a beta that takes inbound calls only, on Pro and up, billed in credits. Mercury's AI front desk answers inbound calls and runs outbound follow-up on every plan.
A power dialer without Enterprise seats
HubSpot's power dialer needs Sales Hub Enterprise. Mercury's dialer runs up to 10 lines per account on every plan.
