With Discounts (menu Products, Kortingen) you lower the prices of a selection of products or variants by a percentage in one go. NEXERA remembers the original price, so everything is restored exactly when the discount ends.
Create a new discount and give it a name, for example "Summer sale".
Choose your selection: the products or variants the discount applies to.
Set the percentage and optionally a start and end date.
Activate, or let the discount start automatically on the start date.
A discount with a future start date gets the status Scheduled and starts automatically.
On the end date, original prices are restored automatically.
You can always stop manually; prices then revert to the original as well.
Shopify
Price changes from discounts are pushed to Shopify on the next sync, both when the discount starts and when it ends.
