Discount allocation for sub-orders
Discount allocation for sub-order splits
Notes

1. Discount allocation for sub-orders

The discount condition is judged based on the amount, product, and payment method in the entire cart. The discount is first allocated according to the total amount of the shopping cart, and then distributed to the sub-orders according to the proportion of the amount.

Please refer to Discounts Allocation to learn more about discount allocations.

*Note:

If the discount only applies to the specified product attributes, e.g., $50 off for buying $500 of refrigerated goods, 50% off refrigerated + frozen goods, the discount will not be allocated to the entire cart amount but to the specified sub-order cart amount. Please refer to the Calculation for specific product discounts below.

To learn more about setting up discounts, please refer to [Coming Soon] Promotion Event Demo | Multiple Product Attributes for Checkout.

Example

The hierarchy of product attributes is: Room temp > Refrigerated > Frozen

Please refer to [Coming Soon] Set Up Product Attributes for more details.

Product name	Product attribute	Unit price x Qty	Subtotal
Room temp product	Room temp	100 x 1	100
Chilled product	Refrigerated	500 x 1	500
Frozen product	Frozen	150 x 6	1800
Total			2400

The promotion applied to the cart number:
- Bundle promotion (A+B) - $50 off for Room temp + refrigerated goods
  $50 off for this campaign
- Order-level discount - 100 off for orders over 1000
  $100 off from this campaign
- Membership offer - $150 off
  $150 off from this campaign

The calculation for selected product discount (bundle promotion)

*Notes:

The system will use the Banker's (round-half-to-even) rounding for price amounts with decimals.
If both decimal points are the same and both need to be rounded up, the system will select the one with the higher amount to round up.

Product name	Product price Unit price x Qty	Allocated discount amount on specific product
Room temp product	100 x 1 = 100	50 x (100 / 600) = 8.3 ≌ 8
Chilled product	500 x 1 = 500	50 x (500 / 600) = 41.6 ≌ 42
Frozen product	300 x 6 = 1800	Not applicable to selected product/bundle promotion
Total	100 + 500 + 1800 = 2400	8 + 42 = 50

The calculation for order-level discount

Product name	Subtotal Unit price x Quantity	Discounted subtotal	Allocated discount amount for order-level promotion
Room temp product	100 x 1 = 100	100 - 8 = 92	100 x (92 / 2350) = 3.91 ≌ 4
Chilled product	500 x 1 = 500	500 - 42 = 458	100 x (458 / 2350) = 19.48 ≌ 19
Frozen product	300 x 6 = 1800	N/A	100 x (1800 / 2350) = 76.59 ≌ 77
Total	100 + 500 + 1800 = 2400	92 + 458 + 1800 = 2350	4 + 19 + 77 = 100

The calculation for membership offer

Product name

Subtotal

Unit price x Quantity

Subtotal after selected product and order-level promotion

Allocated discount amount

for order-level promotion

Room temp product

100 x 1 = 100

100 - 8 - 4

= 88

150 x (88 / 2250)

= 5.86 ≌ 6

Chilled product

500 x 1 = 500

500 - 42 - 19

= 439

150 x (439 / 2250)

= 29.26 ≌ 29

Frozen product

300 x 6 = 1800

1800 - 0 - 77

= 1723

150 x (1723 / 2250)

= 114.86 ≌ 115

Total

100 + 500 + 1800

= 2400

88 + 439 + 1723

= 2250

6 + 29 + 115

= 150

Cart / sub-order amount after discount

Product name	Product price before discount	Subtotal after selected product promotion	Subtotal after selected product and order-level promotion	Subtotal after membership offer
Room temp product	100	100 - 8 = 92	92 - 4 = 88	88 - 6 = 82
Chilled product	500	500 - 42 = 458	458 - 19 = 439	439 - 29 = 410
Frozen product	1800	1800 - 0 = 1800	1800 - 77 = 1723	1723 - 115 = 1608
Total	2400	92 + 438 + 1800 = 2350	88 + 439 + 1723 = 2250	82 + 410 + 1608 = 2100

After the calculation above, the discounted amount of the cart number is $1,000 and the sub-order amounts are as below:

Cart for room temp $82 (excluding delivery fee)
Cart for refrigerated goods $509 (excluding delivery fee)
Cart for frozen goods $1609 (excluding delivery fee)

2. Discount allocation for sub-order splits

You can split the sub-orders generated by each product hierarchy. The discounts will be allocated according to the amount of the split sub-orders. The allocation logic is the same as the one mentioned in the first part of this article.

Please refer to this article for more about the discount allocation for split orders.

Step 1

In the SHOPLINE Admin, go to [Order Management] > [Orders]. Go to the order details and then click the Split button.

Step 2

Enter the number for the "split" field, the system will automatically reallocate the discount amount after splitting the order. Please click Split to confirm.

3. Notes

The store credits and member points of the order are calculated based on the entire cart number.
If any sub-order is cancelled/deleted, the total amount of the corresponding cart number will be deducted synchronously.
(For Taiwan stores) The invoice is generated for each sub-orders. One invoice is issued for each sub-orders.
This feature currently does not support applying product subscription promotions.
This feature currently does not support stack discount applications for order-level promotions/ membership offers. Please refer to store-wide discount application settings for details.
