ContactBook

ContactBook is a shared address book built for teams instead of a single phone. Everyone works from the same set of contacts, edits show up in real time, and you decide who can see which groups. The point is to stop the spread of half-dozen out-of-sync exports living on different laptops.

What ContactBook actually does

It centralizes contacts and then layers sharing and permissions on top, so a team can split records without losing control of them:

• Keep business and personal contacts in one place
• Tag, categorize, and segment records for fast lookup
• Share contact groups across the whole team
• Set per-user access permissions on sensitive groups
• Sync with Google Workspace and Gmail on eligible plans
• Push real-time updates so details stay current
• Catch and clear out duplicate or stale entries

The sharing model is what separates this from a plain CRM contact tab. Because access is set per group, a sales lead can hand a regional list to a rep without exposing the rest of the book, and changes one person makes propagate to everyone instantly. Native Android and iOS apps mean the same contacts travel into a phone dialer rather than getting stranded in a web tool. The Google Workspace and Gmail sync on higher plans matters here too: instead of maintaining a parallel address book by hand, you connect the account people already live in and let the records flow both directions.

Who it's built for

This suits small teams that all need to touch the same contact database: a sales pod, a recruiting desk, a client-services team, or a family office passing records between assistants. If your contacts currently live in one person's Google account and get exported whenever someone else needs them, this fixes that specific pain. The honest counterpoint is the user cap. The lifetime tiers are built around five users, so a growing team will outgrow the entry plans and need the Business tier sooner than the contact limits alone would suggest.

The deal

Basic LTD starts at $89 for five users, 5,000 one-time contacts, up to 50 shared groups, the mobile apps, and email support. Pro LTD at $179 lifts the ceiling to 25,000 contacts and adds storage, reminders, and activity history, while the $499 Business tier opens up Google Sync and unlimited contacts. For a team currently emailing CSV files around, the entry tier pays for itself in saved confusion. [Pick up the ContactBook deal on DealMirror](https://www.grabltd.com/recommends/contactbook-dm/).
