$750-1500 USD

Paid on delivery
I am looking for an individual who has experience writing code for the quickbooks online API. I have a customer who is interested in exporting data from their current accounting system, and push it into quickbooks online for reporting purposes. I am looking for a C# API written to consume the QB API. This project will be able to accept an object from their existing account system and then read/write/update QB online's corresponding object. For example: A new customer is created in my system, my system will consume your new API, pass it a customer object and the API will create this customer in QB Online.
