Build a Voucher creation website

Our current site was built in 2015 and it shows. It’s our goal with a new plan that we’re introducing new e-commerce website and is under development. Additionally, we would like to introduce promo code & gift vouchers in website. These code/ gift vouchers are generated & send to our regular customers by email from a separate website. Users can redeem this promo code online when ordering from our website or use the gift voucher in third party shops, like a coffee shop or flower shop to get the items at a discounted price. Code/gift voucher creation website will work as an add-on, in order-to make things more efficient and track marketing and processes better. We’ll need a site that we can manage, that will look great, allow us to create promotional campaigns, promo codes, vouchers, and redeem it easily. The site should also be better targeted to our site administrators. connect with new database, and the administrator can work with the vouchers. These voucher codes can be used when ordering products. When a code is entered, this code will be validated with the database. If the validation is success, discount shall be applied in the total amount. Process involved: 1. Site administrator shall be able to login to the new web site, create campaigns, promo code and vouchers. 2. These created vouchers will send to end users, mailing functionality should be there. Mail addresses can be retrieved from our master database. We will provide temporary database schema and data. 3. While creating the vouchers, there shall be an option to choose the types; discount coupon or gift card. 4. The vouchers are redeemed from the e-commerce site. The e-commerce website expects a redeem API, (POST request to voucher site) and results, whether the code is applied or not. If yes, the redeemed value. Else the error details.
