Excellent service and tools, but after some time we found that they were just not enough for us. We use it internally for other purposes and it does what we need, but if we want to scale it up to higher volumes, it just doesn't cut it anymore. It takes too long to get things done. It seems that people there don't communicate as efficiently as they should and tend to work in silos. There is no single person responsible for certain tasks and everyone has their own system, so even simple tasks take forever. You can't reach anyone. And when you try to contact someone directly, they just don't respond. So it's not a question of skills or knowledge, but rather a lack of understanding of how to handle projects, customers and tasks effectively. They seem to have way too many projects going at once, and not enough resources to do them properly. As a result, there are often delays, scope creep, poor quality, etc. It's hard to estimate the number of hours spent on projects that end up cancelled due to problems, and it seems like they have little idea about how much time they actually spend on clients' projects. There are a lot of rules and processes in place, but you never know when or why they are applied.
