Hi There,
I am having expert level experience in QuickBooks Online and desktop integration. I have experience in all most all the modules in QBO and QBD like Invoice, Estimate, Refund Receipt, Customer, Chart of Accounts, Product and Services, Sales tax modules etc. I am very much familiar with their API explorer and the .NET SDK provided by Intuit.
I already have developed a data migration solution from QuickBooks Online for one of my customers.
Please let me know your convenient time to discuss further on this.
Kind Regards,
Mayuri Patel.
