Comparison

OpenPhone vs Grasshopper: which business number service?

Reviewed by Sujan ThapaliyaLast updated

The short answer

Grasshopper forwards a business number to phones you already own. OpenPhone is an app you actually work in, with shared numbers, a shared inbox and team collaboration. For one person who wants a professional number on a personal mobile, Grasshopper is simpler. For a team handling conversations together, OpenPhone.
Flat per-seat licensing plotted against metered usage over connected minutes: the licence is $750 a month regardless of use, metered calling starts at zero and rises at $0.020 a minute, and the two only meet at 37,500 connected minutes. Where your team sits on this chart decides most comparisons of this kind.
Most comparisons in this area resolve to volume rather than features.

Which to choose

Which one should you use?

Grasshopper for one person who wants a business number

It does exactly that, cheaply, without another app to live in. Calls arrive on the phone already in your pocket and the business looks larger than it is.

OpenPhone once more than one person answers

The moment two people need to see the same conversation, forwarding stops working and a shared inbox starts. That is the line between these two products.

Neither, if the team calls out at volume

Both are built around a number and the conversations on it. Neither has dialling modes, caller-ID branding or attestation, so an outbound list is dialled by hand and increasingly labelled.

Frequently asked questions

Can Grasshopper handle a growing team?
Up to a point. Extensions and forwarding scale to a handful of people, but there is no shared view of a conversation — two people cannot both see what a customer said. That is usually what forces the move rather than any hard limit.
Do both keep my personal number private?
Yes, that is the main reason people buy either. Outbound calls display the business number rather than the mobile underneath it.
