I work for a Salesforce consulting composer, and I'm mostly a developer, sometimes an admin. Sometimes the clients require us to set up things in Conga, either Conga Composer, Conga Sign, or any other similar application. So most of the times, the request is just to update existing templates or create new templates for them to use on Conga.
There's nothing in particular. It's just what the client decides to use. I just use it. It's quite simple. Most of the clients do have it. It's better than having to go in and do it manually, creating a Visualforce page to use as a template, which is another thing that we do here. If the client only has one template to use, then we recommend that they go that route. However, if they do have many templates or they need to be changing them constantly, and it's more expensive for them to hire us to change them every time, then we usually recommend that they use something like Conga.
The documentation could be improved. The one time that I learned a bit more on how to use it was when I got into Conga University to get my certification. There are a lot of small steps that you don't see in the standard documentation or you cannot find it. A couple of years ago, they changed stuff from what I learned five years ago when I started, which is great. However, they need to update documentation to match that. Sometimes, you find the documentation for the old version, and you try to do it, and it just doesn't work.
I've used the solution for five years.
Most of the time, I haven't had an issue like that, not human-related. If I made a mistake of adding something that shouldn't be there, or sometimes you start with a template that somebody else made, and then you paste it and think, 'Okay. That's just going to work,' but it doesn't because it has a little bit of something that it doesn't like.
It's always better to start from scratch. Otherwise, I've never had a significant issue. Maybe once I got a weird error, and then I noticed that there was a crash on the servers from Conga, and that's probably the reason it failed.
I'm not sure if the solution is sclable. I don't see any issues in adding more templates as the company is growing. However, I've never done anything big with it. Everything is just like, 'Okay. We have these five templates, ten templates at most.'
I've reached out to support many times based on the documentation. I'm trying to follow it, and it doesn't match what I'm seeing, so I end up having to contact Conga directly for them to let me know that the issue was that I do not have the license that they need for that.
I would recommend this product to other people. If they need to have a lot of templates and need to make changes often, like every three months or less, then I would say they should go the route of using either Conga Composer or any other similar application.
I'd rate the solution eight out of ten.
