cs cart export to quickbooks

Looking for someone that can help me export orders/clients/products from cs cart multi vendor to quickbooks online using the qb essential plan. I purchased the 2 addons in the marketplace but can't get either to work. The opencartcity addon only works with the more expensive QB plan. The simtech addon is operated by a bunch of idiots with the worse tech support out there and they can't get their own addon to work. Looking for options.
