Shopify free shipping is not setting every rate to zero. Compare order value, margin, region, delivery time, returns, and conversion path. A cross-border store should set thresholds by market and shipping zone so cart, checkout, order, refund, and support all show the same rule without silently consuming margin.
Set thresholds from order and delivery facts
Record product cost, packaging, carrier, zone, weight, timing, returns, tax, and margin. Test threshold, selected product, loyalty, market, and stacking conditions. Explain the threshold before checkout rather than changing it at the final step.
Review net margin and experience
Join shipping, discount, payment, tax, refund, and support cost to order ID. Review AOV, margin, delays, returns, abandonment, and repeat purchase instead of conversion rate alone. Remove campaign banner, code, collection, ads, and structured data after expiry.
FAQ
Does free shipping always improve conversion?
No. Margin, delivery, returns, abandonment, and long-term value matter.
Should every country use one threshold?
Usually not. Cost, currency, tax, and shipping zone differ.
Can free shipping stack with discounts?
Test explicit rules so cart and checkout agree.
How can profitability be measured?
Calculate net profit after shipping, refunds, support, and discounts.
