I’m not a staff member, but I currently downloaded CS-Cart and it doesn’t appear to have an Order Export. I believe a few probably have brought this up in various threads. It is also important for my store.
I hope it comes out in the next version.
What type of exporting do you need for your accounting application? Nearly anything can be modded including the payment gateway so there is little worry about other than timeframe and costs.
CS-Cart is still new but is very expandable and actively developed with new talent arriving on a regular basis. If there is something you are needing customized then, chances are good it could happen within a good timeframe and still at lower costs than other solutions available.
