FAQs
How do I accurately quote a mixed cart containing small accessories and large body panels?
With Dimensional Packing, ShipperHQ can rate products of all sizes accurately — from small filters and brackets to hoods, bumpers, and kits that never fit in one box. Instead of rating by weight alone, ShipperHQ uses a best-fit algorithm that factors in actual product dimensions, package sizes, and packing rules to calculate rates based on dimensional weight. You can define how items pack into boxes, which items ship separately, and which items pack onto pallets.
Products can be organized into shipping groups so ShipperHQ knows which items are parcel-eligible and which require LTL freight — whether you want to rate them as separate shipments or together. For items that need LTL, live freight quotes or custom rate tables apply the correct freight class automatically.
Customers see accurate options for each shipment instead of a flat rate that erodes margin or a dead-end "call for a quote."
How can I eliminate manual freight quotes and show live LTL rates at checkout?
How can I eliminate manual freight quotes and show live LTL rates at checkout?
ShipperHQ connects to 30+ LTL freight carriers to return live rates at checkout, eliminating manual freight quotes. For automotive catalogs with oversized parts like bumpers, hoods, fenders, and exhaust systems, customers get a real shipping price immediately.
You control which products trigger LTL using shipping groups and assign freight class at the product or group level. For carriers that don't support live rating, custom table rates can be used to display accurate freight prices based on weight, zone, or any combination of conditions. Accessorials like liftgate, residential delivery, inside delivery, and limited access can be included in the checkout rate based on your configuration.
LTL freight shipping in ShipperHQHow do I make sure residential delivery surcharges are applied correctly for auto parts orders?
ShipperHQ automatically detects whether a delivery address is residential or commercial at checkout and applies the correct surcharges before the order is placed. This prevents you from absorbing carrier address correction fees after the fact, which can run around $20 per shipment with UPS and FedEx.
Address validation also catches invalid addresses and can suggest corrections at checkout, reducing failed deliveries and re-shipment costs.

ShipperHQ's Rate Shopping feature automatically compares rates across your configured carriers and displays only the lowest cost option for each shipping method at checkout. You can present a single best rate under a simplified method name like "Standard Ground" rather than listing every carrier option separately.
Rate Shopping works alongside your existing shipping rules, so carrier exclusions, surcharges, and restrictions are applied first before the comparison is made.
Rate Shopping in ShipperHQHow do I offer in-store or curbside pickup for large automotive parts?
ShipperHQ supports in-store pickup as a delivery option at checkout alongside standard shipping methods. Customers can select from available pickup locations, and you can restrict pickup availability by product, location, or customer group so only eligible items and approved locations appear.
For parts that need to ship from a warehouse to a dealer or store before pickup, Ship-to-Store supports live carrier-calculated rates to the pickup location so customers see an accurate price and can choose the closest available point.
In-store pickup in ShipperHQHow do I calculate accurate dimensional weight for large, light car parts like bumpers?
ShipperHQ calculates dimensional weight using your product dimensions, box sizes, and carrier-specific divisors so checkout rates reflect what you will actually be charged. Automotive parts rated on volume rather than physical weight need accurate dim weight calculation to protect margins.
You define box sizes and ShipperHQ selects the most efficient packing configuration. Products like large body panels can be flagged with a Pack Separately rule to prevent incorrect grouping. Dimensional Packing is available on Standard plans and above.
Dimensional packing in ShipperHQHow can I restrict shipping methods for hazardous fluids or oversized engine components?
With the ShipperHQ Shipping Rules feature, you can hide, restrict, or force specific methods based on cart contents and destination. You can block air shipping for fluid-containing products, restrict oversized parts to ground or LTL, or force specific carriers for special handling requirements.
Rules are based on cart weight, price, quantity, shipping zone, shipping group, and customer group. On Shopify, some customer group conditions have platform limitations.
How do I handle shipping rates when auto parts ship from multiple different warehouses?
ShipperHQ calculates shipping rates from each warehouse and presents consolidated options at checkout. For automotive retailers, this supports setups where small parts ship locally while large items like bumpers, hoods, or exhaust systems ship from a regional warehouse.
Each origin has its own carriers and rules. When a cart spans multiple locations, ShipperHQ rates each shipment and combines the results into a single total or separate options by origin, with split display available.
Origin selection can be based on proximity, warehouse count, or product assignment. This works across parcel and LTL carriers, so mixed carts are rated accurately in one checkout.
Multi-origin shipping in ShipperHQHow do I offer conditional free shipping on small auto accessories?
ShipperHQ lets you apply free shipping to qualifying products using Shipping Rules. You can target specific product groups, set order value thresholds, exclude freight items, or limit offers to certain customer segments.
For example, you can configure small accessories to qualify for free shipping above a cart value threshold while oversized or freight-class parts always show live rates regardless of cart value.
Can I show exact delivery dates to buyers working against a repair schedule?
Yes. ShipperHQ shows exact delivery dates based on lead times, cutoff times, blackout days, and carrier transit data.
For buyers working against a repair or build schedule, this provides a clear arrival date before purchase – essential for customers working against a tight repair schedule. Each shipping option shows a carrier-specific date so customers can choose with confidence.
