Love that Sigma lets me work multiple quotes at one time and because it's so powerful and well designed, I can get quotes done in half the time it would take otherwise.

Powerful and adaptable. LOVE the fact that you can attach quote documents, images, etc to the scope lines. I like to use the child fields to insert the various quotes from subcontractors. Then I can just turn them on or off as needed to work my quote. Customer support is AWESOME! I can call them any time and 85% of the time they'll answer right away. If he doesn't answer I know he'll be calling me back shortly. He'll work me through most issues while we are on the phone! If he can't do that, he'll find a fix for the issue and get it right back to me. Like I said, AWESOME!!

Steep learning Curve... Lol! But.... See above regarding customer support!

Hands down, best money ever spent on estimating software. The potential of Sigma is huge, and integrating it with other digital takeoff software like Planswift creates a match made in heaven.

Extremely flexible to your needs. Unlike other estimating software, Sigma allows you to build your own system through a very familiar excel interface. The modular structure of Sigma also allows you to quickly and seamlessly modify/add/delete anything in your quotations and even reference part or all of it for future estimates.

The report system is not very user-friendly, still a lot of improvements can be done in this area in terms of customization of reports.

To the extent Sigma is utilized with hand crafted libraries and physically organized BOQ the product is incredible, when you need to go further and set up an adequate BIM work process - there it starts to get confounded.

Interopairability with Autodesk Revit for direct BOQ and probability to develop project tree.

Intricacy in information trade and planning settings between 3D models as local as IFC.

I use this daily and cannot estimate my projects without it.

I love the scripting and the ability to "nest" assemblies within the system. This ability is so powerful and blows the doors off of anything else out there. The ability to import price lists and update libraries is critical to keeping your estimates up to date.

Documentation is being improved. More details on the scripting is always helpful. The online help is good but examples and templates using all of the commands is helpful for someone who is not a programmer or wants to see what each command does.

What I like most about Sigma is that I was able to pick up on it very quickly. I had no problem turning the software into my own, and making templates so my estimating went smoothly.

Its hard to say what I like least because I have not run into any problems where it has changed my thoughts about the software.
