I need someone to use the QuickBooks API to update accounting data in Quickbooks. The routine must be able to: 1)create items, create customers, create Invoices & Sales Receipts. It must also check for duplicate customers by address and/or phone number. For example Ralph Smith could also be R. Smith or R A Smith all with the same phone number and address. If you are interested, I have the code in VB6 that creates the XML for the same functions for QuickBooks desktop. It appears that the same XML will work here. Use the work blue in the first sentence of your response.
