LSA is a great agency to work for. Invoicing is very easy and user friendly right on their website. Everyone who works there with whom I have interacted is very friendly and has excellent customer service skills to get the problem solved. Payment is always on time, and the payment schedule, although a little bizarre, is pretty clearly explained ahead of time and in each email confirmation. The system for accepting assignments is easy to use and makes sense, but it can be frustrating at times when you lose an assignment because you don't have internet at the moment or when one of your jobs gets canceled and rescheduled and instead of you being asked directly for the rescheduled job first it goes instead into the system so that whoever responds first gets it. Once you have a job there's an extra verification step to opening up the email so that's kind of a pain and makes it so you try your best not to open up the email again. These are just nitpicking things because overall this agency is one of my favorites in terms of ease of invoicing, great customer service, and variety of assignments/clients. I have and continue to recommend this agency to others!
