Easy Setup Guides

Why DejaOffice is Best

Act! Mobile without a Web App

Your Act! Contacts, Activities, Notes and History are available in DejaOffice whether your phone is connected or not. If your phone is in airplane mode, or outside a signal, you can still change a contact, add a note or and schedule an activity. Next time you connect your PC will "catch up".

Use Android Widgets with Act!

Android phones have Widgets on the Android Desktop. DejaOffice widgets can show your full contact list, and your full day's schedule without ever opening an app.

See All your Contacts on your Phone

No limitations to the number of contacts on your phone!

  • Android - DejaOffice has no limit, only your phone memory. We've seen customers use 60k contacts or more. We recommend limiting native Contacts to 8k or fewer for performance. You can control this in DejaOffice for Android.
  • iOS - DejaOffice has no limit, only your phone memory. We've see customers with 15k contacts or more. If the iPhone has an updated OS, the OS takes more memory so you may be limited to 8k or so on the native Phone list.

Persistent Alarms on your Mobile Phone

Alarms will ring quietly until they are dismissed. Never miss an appointment because you were away from your phone for a minute.

Quickly create activities and history

A mobile phone is not a PC. DejaOffice CRM is designed with your fingers in mind. Every screen tap and swipe is focused on getting you the right info, enabling fast data entry, and completing your day.

RunStart configuration service

Schedule an appointment for a CompanionLink expert to set up your synchronization system. Our technician will securely log in to your PC and get everything working.

BEST Company support EVER

I have used Companion Link products for 15 years. The staff is SO supportive, professional, polite, pleasant and MOST OF ALL - PATIENT. In my 70's and there are days that technology could put me under a cloud. Michael, Thomas, Waylon and the WHOLE TEAM are such a joy to speak with and ALWAYS find the solution to any issue I present to them. They ALWAYS return my calls and/or emails. YOU CANNOT go WRONG with Companion Link!

I needed to have my laptop repaired which forced me to have it wiped clean and then restored.
I am not a computer person and rely on Technical support people to walk me through the process. Tiffany D was wonderful. Patient with a person like me who is not computer technical AT ALL!!
We walked thorough each step and got the Software program up and running again.
What great service, Thanks Tiffany
Great support

I felt the need to write a review for this product. I have been a client for Companion Link for many years. On rare occasion I would contact Customer Service and usually it was something that I did not do right. Recently I experienced an issue with calendar data not being visible after the calendar date of the event on my Android phone which was bothersome since I needed that information available. I contacted Customer Service and Conley reached out to assist me. and I cannot say how efficient and pleasant it was to work with professionals!! While it was a very unusual issue the Customer Support Team did not rest until they had resolved the issue completely. I wish I could provide a higher review than only 5 stars because it is deserved. I will stay with this software because it just works right and the support is unbelievable!!!
The BEST tech team EVER!!!

Following and upgrade for my ACT software to vs24, I received Companion Link Express error messages. A call to CL and in 5 minutes a return call from Michael. The BETA build for this error was installed, and I'm back in business.
This team, led by Waylon B, is SO responsive and a JOY to work with. Michael ALWAYS makes me feel like I'm the ONLY client he has to work with :)
I cannot thank this group enough for their abundant professional, knowledgeable, polite, and VERY PATIENT service to this 72 year-old gal! Not to mention the software has been stellar for my previous cell phones, and now my Galaxy S21!
How smooth was that!

Setting up my new phone could not have been a more pleasant experience. Michael made quick work of creating a wireless sync from my desktop to my phone and I'm up and running not missing a beat AND with all my contacts and calendar settings in place.

Many Thanks and Merry Christmas Michael!
