Reviews of Sage 100 Contractor


Sage 100 Contractor is user friendly and was a breeze to figure out. I have rarely had to call for support. I am the controller for a GC and I, as well as the project managers, have been very happy with this program.

The good: The ease in entering transactions.

The bad: There is not much to say here. I do think the self made reports could be a bit more user friendly.

The good: There’s very little to like best. If I was forced to say something positive I will say the “best” thing about SAGE 100 was uninstalling it off our computers. This is a very long list. I will try and condense it. To start with you go through a 3rd Party vendor. SAGE doesn’t even participate in the sales portion!!! Instead they have misinformed 3rd party sales agents selling you the product. They sold us add-ons and “turn-key” solutions that they claimed would solve not only our Accounting needs, but also estimating, project management, and document control. Unfortunately these products fail miserably to achieve those goals. The support is a joke. We had multiple “conference” calls, meetings, etc. all charged to us of course. These solved very little and usually left us with more questions than answers. I could go on forever, but at the end if you are looking to SAGE run away very fast!!! . First and foremost know what you need. Don’t get caught up in all the bells and whistles they try and sell you on. Secondly make sure to have a full demo. Once you purchase the software any training or discoveries are on your dime not theirs. Before you actually buy the software ask for a 30-day trial. Any company not willing to offer you that must not feel confident about their product. Purchases like these are a huge deal for companies treat that decision with delicacy… don’t rush in!!!

. SAGE 100 is a bulky hard to use software program out of the box. It is designed for you to have problems so you have to call support for help (and of course get charged for it). Unless you are a SQL Database programmer this is not the program for you This product not only didn’t meet our needs, it hindered us. It set us back 6 months easily. By the time we had spent thousands of dollars setting it up we realized that everything that we had been told it would do would either require an upgraded version of the software or additional programming that we were not made aware of upfront. At the end it did accomplish basic accounting/payroll, but we had to implement various workarounds to even achieve that. Customer support is all over the place. SAGE offers what they call SAGE University. Unfortunately all the real helpful stuff is videos that you have to pay for. Just to get a manual I had to call a SAGE representative directly to email me one. Even then he said he wasn’t really supposed to do that. In addition any specialized support has to come from your 3rd party sales representative. Of course they charge you for every phone call, meeting, on-screen help sessions. In my opinion SAGE needs to own their support and include it in the initial purchase agreement. That way you aren’t getting billed for every little thing. It won’t solve their inferior product, but it would at least be a start in the right direction

The bad: Isee #4

from Richardson Housing Group says…

I found it to be user friendly and very easy to work with

The Good: User friendly.

The Bad: Nothing so far.

from North Star Restoration says…

We are a restoration company, not strictly builders and we work with insurance company’s and insurance claims and it would be nice to have some feature built into the software as far as the insurance company that we work with to see where the work comes from.

The Good: It is user friendly. It is also similar to QuickBooks but a bit more complex than QuickBooks and has more functionality that an accountant would use and I am an accountant so I like that.


Some of the features we would like it to have would be online banking.

The Good: It has contract billings.

The Bad: Inability to import banking transactions
