Sales Discount-Coupons
With osConcert... it is possible to generate unlimited Discount-Coupons or Gift Vouchers.
The Administrator can send COUPON CODES to registered customers.
Customers can REDEEM  codes at the Checkout Payment  page.

Admin>Orders>Vouchers/Coupons>Discount Coupons (Enable existing Coupons here)

Goto Admin>Orders>Vouchers/Coupons (Set up new coupons here)

Click the ‘New Discount Coupon’. Create the conditions for your Coupon with the help of the guide on the right side.

We can create Fixed Discount or Percentage Discount (add %  to the  value)
Usually the “All Categories” is suffice but you can apply the discount coupon to a certain category or product.
Click the PREVIEW button and click the CONFIRM button when  you are satisfied the  conditions  are  correct.

This should save the coupon to the Coupon Name list and you may need to click the status button from RED to GREEN to activate it. Admin>Orders>Vouchers/Coupons>Discount Coupons

That should have created and activated a coupon and its COUPON CODE that you can send to your customers.

Customers  will  be  able  to  see  this  page...where  they  can  enter  their  given  Coupon  Code  and  Redeem  their  coupon  with  the  Validate  Button

But before we do that we should also set the Order Totals in the osConcert to display coupon discount correctly at checkout.
Admin>Payment>Advanced>Order Totals

In the Order Totals module first DELETE the already installed modules (SubTotal, Total etc) and then RE-INSTALL with Discount Coupons most likely your second module, AFTER SubTotal and then the Total module must be the last to install.

This will give a correct order display in the checkout confirmation page.

Emailing Discount Coupons
After the Discount-Coupon is created it can be emailed to your customers. Click and highlight the Coupon-tab and click on the EMAIL icon to open the coupon-email generator.
From the pull down menu, select to whom you want to email the Discount Coupons to. Use the wysiwyg editor to edit the Discount Coupon text.

Click the PREVIEW button to preview the Discount Coupon Email. Then click the SEND EMAIL button.
Your customers will receive the Coupon by email.

All a customer need to do when they receive the COUPON code from you, is tick the Redeem Gift Voucher tick-box on the front end and enter the Voucher code in the appropriate REDEEM box where it now appears in the checkout payment process.

Note that the discount will be calculated and shown in all Order Details and in Reports inside osConcert.
