E-voucher Web App (1758536)

We are looking for an e-voucher app to be integrated with the newsletter signup on our wordpress website. Here's a breakdwon: 1. A 10% discount is offered to customers as an incentive to associate with our brand. 2. Customers sign up online 3. As the subscription is complete (webform is submitted) they are presented with the e-voucher and asked to print or save it for printing later (could also be emailed to them) 4. The voucher will be pre-populated with unique identifiers (name, email, maybe phone number) so that we can tie each voucher to a definite subscription and track redemption of the discount 5. The app needs to be able to communicate with QuickBooks for integration with our back-end.
