On activating Markup Pricing it gets applied to all new products imported via Spreadr. Existing products can be marked-up by enabling 'Update prices as per Markup Pricing Rules' option in the Auto-sync settings.
Steps:
Activate Auto-sync (ignore if already activated)
Go to Spreadr Dashboard Homepage and search for the product you want to mark-up.
Click on Settings (Actions column).
4. Select 'Update prices as per Markup Pricing Rules' option and hit 'Save'.
5. Repeat for all products you want to markup.
These products will be marked up as per your pricing rules when Spreadr executes Auto-sync once every 24 hours.
