My WooCommerce store must mirror an existing platform’s discount logic while remaining easy to maintain. The immediate tasks are: • Obtain information for the correct co-configuration of the various discount systems. • Build a bulk-manageable percentage system that tags discounted items so AJAX filters instantly recognise them and can be correctly shown in the catalogue. • Set up fixed, customer-specific pricing tiers subdivided into two cats: – EU Company → 18.03 % off – Long-standing Customers → 10 % off Percentage and customer-specific discounts take priority over generic coupons, and everything has to stay future-proof for migrations or theme updates. I need clear advice on which plugins or native WooCommerce hooks best deliver this—think Discount Rules for WooCommerce, Advanced Coupons, Dynamic Pricing, or any better alternative—and hands-on configuration until the results match the original site’s behaviour. Please send a concise proposal outlining: • your recommended tool stack and why • the setup flow you’d follow to replicate existing rules • how you’ll verify that discounted products remain filterable through AJAX search A successful hand-off includes documented settings or snippets so my team can adjust percentages later without breaking anything.
