Developing C# application for Sage 50 Quantum Accounting 2019.3 (Canadian)

Hi Team,

I am new to Sage50 SDK development in C#. My Sage version is "Sage 50 Quantum Accounting 2019.3 (Canadian)"

Getting started understanding development process, I downloaded Sage50SDK20193 and installed it. Here i found C# sample code, and it is working as it supposed to.

I am trying to create customer/quote record using code, but sample code shows  how to create all using Journal entry and fields are very limited.

For example I cannot set Cutsomer - Ship to address during creating customer (as per sample code), same for Quote i cannot add more than one Item in it.

After searching over this forum and google I found I am missing something called PeachTree, may be i am not on correct path, please guide me. What dll references I need to add to get complete access to create quotes/customer/orders with full details?

How can I create Customers/Quotes with complete details which are available in customer UI of Sage ?

Would appreciate any help on this.
