The customer VIP program module makes it possible to set up a discount rewards system for your customers based on their total spendings. It'll help increase your sales by offering your loyal customers discount on products and incentive to spend more to receive additional discounts.

Main features:
+ Set any customer membership levels (i.e. Bronze, Silver, Gold, Diamond) with badges
+ Set customer spending threshold for each membership level.
+ Customer spendings can be based on all orders, last quarter orders, or last month orders (v0.3+)
+ Set whether or not to include shipping in customer total spending calculation
+ Set order status (i.e. complete, shipped, processed, etc.) to be included in customer total spending calculation
+ Admins will be notified via email when a customer achieves a new level
+ Admins can filter customers by VIP membership
+ VIP discount is only applied to regular price (non-discounted and non-special price) products
+ Customers can see their membership statuses (current level, current discount, and amount needed to reach next level) when they log in
+ Regular and VIP discounted price will be shown for eligible products on all pages
+ This module comes with sample trophy logos (Bronze, Silver, Gold, Diamond) free for you to use. Please contact us for custom logo.
+ Customizable messages (v0.3+)
+ Support multiple languages (v0.3+)

VIP status is automatically calculated based on historical "completed" orders. There are 5 types of calculations that you can choose from: All, Annually, Semi-annually, Quarterly, and Monthly

Example: Today is Apr 1, 2017, Bronze status is 500, Silver status is 1000, and Gold status is 2000

All: Use all orders. To date, John spent 1500, his status is Silver. Whenever he gets above 2000, his status will be Gold.

Annually: Use orders from last year (2016). In 2016, the John spent 700. In 2017, his VIP status is Bronze. If he spends 200 in 2017, his status for 2018 will be none. If "Use current period" is checked, it will use orders from current year (2017)

Semi-annually: Use orders from last half of a calendar year (Jan 1 - Jun 30 and Jul 1 - Dec 31). Between Jul 1 and Dec 13 of 2016, John spent 1100, his status is Silver between Jan 1 and Jun 30 of 2017. If he spends 1200 between Jan 1 and Jun 30 of 2017, his status for the next half of the year will also be Silver. If "Use current period" is checked, it will use orders from current half of the year (Jan 1, 2017 - Jun 30, 2017)

Quarterly: Use orders from last quarter (Q1: Jan 1 - Mar 31, Q2: Apr 1 - Jun 30, Q3: Jul 1 - Sep 30, Q4: Sep 1 - Dec 31). Quarter 1 of 2017, John spent 200, his current status is none. If he spends 700 this quarter, his status for Q3 of 2017 will be Silver. If "Use current period" is checked, it will use orders from current quarter(Apr 1, 2017 - Jun 30, 2017)

Monthly: Use orders from last month. Last month John spent 2200, his status is Gold. If he spends 700 this month, his status next month will be Bronze. If "Use current period" is checked, it will use orders from current month (Apr 1, 2017 - Apr 30, 2017)

Days from Today: Use orders from specified days from today. For example days from today (Apr 1) is set to 60. It will calculate VIP status based on orders between Jan 31, 2017 and Apr 1, 2017.
