Add-ons for Reckon Hosted to automate invoice entry

I'm looking for an add on for Reckon Accounts Hosted Australia, for automatic data entry of supplier stock invoices. We create purchase orders in Reckon, so I'm looking for an add-on which will enter stock items based on product code and qty automatically when the supplier invoice is uploaded. This needs to be integrated to Reckon since the purchases orders will still be created using reckon

Is there any software which caters to this requirement. ??
