Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureHigh shipping rates kill conversions for small items. But standard Shopify settings double-charge customers by stacking Lettermail and Parcel rates at checkout, leading to even more abandoned carts. FixShip solves this instantly. Tag your lightweight products, and our logic does the rest: Lettermail pricing appears only when the entire cart is eligible. If a parcel-sized item is added, the Lettermail rate vanishes.
Set up custom shipping rates, rules and discounts in minutes - no coding required. Create shipping rates using product, cart, customer, zipcode, distance, metafields, dimensions and 25+ params to control exactly what shipping rates customers see at checkout. Show live carrier rates, tiered rates, per item rates, percentage rates, etc. Blend shipping rates from multiple profiles or rules.
- Clear logic: lettermail option available if and only if it should be
- Streamlined configuration: add lettermail rates & product tags and you're set
- Non-intrusive: Shopify-native performance invisible to customers
- Set shipping rates by 25+ parameters like product tag, cart total, pincode, etc
- Assign different package sizes for different product & show live carrier rates
- Charge shipping rates per product in cart
- Avoid doubling of shipping rates because of multiple locations (flat rates only)
