What this guide helps you do
Set tax/service/packaging charges and store promotions, understand their calculation basis, and test voucher or quantity offers before customers use them.
Before you start
Use the store's configuration/inventory permission. Decide the names, amounts, scope, and active dates. Check the store currency and timezone before typing money or dates.
Where to find it
Partner → Charges or Promotions; both are behind More on a phone. These are separate from a descriptive sale badge and from delivery fees on Delivery.
Step by step
-
In Charges, add a charge with a clear Name, such as Packaging or Service fee.
-
Choose Percentage or Flat and enter the corresponding value. Percentages follow the displayed valid range/decimal rules; a flat amount uses the store currency.
-
For a percentage charge, choose its Basis: subtotal before the promotion or subtotal after discount. Flat charges do not use a percentage basis.
-
Save, enable the charge when ready, and reorder the breakdown if needed. Disabling keeps the setup without charging it.
-
In Promotions, add a Name and choose Percentage, Flat, or Tiered quantity. Combo bundles are not offered in the current form.
-
For a tiered quantity promotion, add each minimum quantity and its percent/amount discount. Check that the tiers increase sensibly; the highest qualifying tier applies.
-
Choose Scope: whole store, category, or specific products. A shop parent-category scope includes the products in its subcategories.
-
Set Minimum basket, Start and End in store time, optional Voucher code, Funded by, and the offered priority/enabled controls.
-
Save the promotion and confirm the intended active window. A code must be entered by the customer; an offer without a code can qualify automatically.
-
Inspect customer checkout with a qualifying and nonqualifying basket, and test the code spelling and scope. Review the discount and charge lines in the breakdown.
-
When several offers qualify, expect the best applicable single promotion. A voucher and an automatic promotion do not stack.
-
Changing an offer affects new checkout calculations. Existing orders keep their stored price and promotion snapshot.
Understand the choices
-
Charges use their own basis; rearranging them does not make one compound on another. Delivery is applied separately.
-
Minimum basket of zero means no minimum, not a free order. Quantity tiers count only the in-scope quantity.
-
Funded by is a classification of the promotion. It is not proof that an automatic bank reimbursement will occur.
-
A voucher cannot force a worse offer over a better qualifying offer. The pricing engine selects the best single discount, with configured priority breaking ties.
-
Do not duplicate a charge in both a legacy formula and the operating Charges configuration; inspect the actual customer breakdown.
Check the result
The saved enabled charge/offer appears only when its conditions apply, with the correct subtotal basis, scope, time window, and single promotion in the customer breakdown.
If something goes wrong
-
Code not accepted: check spelling, active dates, enabled state, scope, minimum basket, and quantity.
-
Discount not stacked: this is intentional; compare the single chosen offer.
-
Percentage error: follow the value field's allowed range and up-to-two-decimal precision.
-
Offer starts at the wrong time: review the store timezone rather than your device timezone.
