Hello,
If you agree in writting the small apps by using C# I could arrange a quick solution which is utilizing Quickbooks SDK v13. But I need to know what QBD version you are using. Also I require to know the sending QB entities to your web apps is over RESTfl endpoints or simple HTTP POST, and need to know the structure of JSON data request you require. Once you agree with my offers and answer my questions, this would be a n over weekend job.
Let me know
