Shipping rules are evaluated before the default carrier and service. Keep the
fallback defaults sensible, but use rules for intentional routing.
Open Shipping Rules
- Open Settings.
- Choose Entity Settings.
- Open Shipping and Fulfillment.
- Choose Shipping Rules.

Build A Rule
Review each field:- Location scope: all locations or one warehouse.
- Weight range: separates small parcel, heavy parcel, and edge cases.
- Order value: applies different routing for high-value or low-value orders.
- Sales channel: handles Shopify, Amazon, phone, counter, or wholesale differently.
- Product category: routes hazardous, fragile, oversized, or special categories.
- Carrier tokens: limits which Shippo services are eligible.
- Preferred carrier and service: guides auto-select and auto-buy behavior.
- Free shipping or flat rate: controls customer charge policy.
- Priority: lower numbers run earlier.
Freight Classification Rules
Freight rules decide whether an order should stay parcel, move to LTL freight, suggest review, add accessorials, or block the order. Test freight rules with known orders before relying on them for live routing.Common Blocks
- Wrong rule matched: review location scope and priority first.
- No carrier rates appear: check Shippo, address validation, package dimensions, and allowed carrier tokens.
- Flat rate differs from carrier cost: flat rate is the customer charge policy, not the carrier invoice.
- Freight order stayed parcel: check freight rule conditions, product freight flags, dimensions, and weight.
- Auto-buy selected an unexpected service: review preferred service, service tokens, and auto-select cheapest settings.
