After getting started with shipping in SKULabs, you can start exploring additional features aimed at helping you take the next steps toward optimizing fulfillment.
Add weights, dimensions, and customs information to your items
Enter item details such as weights, dimensions, and customs information into SKULabs so the ship screen can fill in shipment information for you. Item details can be updated or imported in bulk via CSV, or by opening an item's details and clicking the Edit button:
The Edit button on an item's details page, where you set weight, dimensions and customs details.
How the ship screen picks weight and dimensions
When you open the ship screen, SKULabs fills in weight and dimensions from the first source below that applies, then runs your shipping rules on top:
Saved draft shipments. If the order already has unshipped draft shipments, they are loaded exactly as saved.
Shipment memory. If you shipped the same combination of items before with Memorize checked, SKULabs reuses that shipment's weight, dimensions, package type and box. If the memory has no weight, or your store has Prioritize item weight over memorized weight turned on, the weight is recalculated as in step 4 and the memorized dimensions are kept.
Boxify packing summary. If the order came with a Boxify packing summary, its boxes and weights are used.
Calculated from your catalog.
Weight: if the order is exactly one kit and the kit has a weight, the kit's weight is used. Otherwise, if every item has a weight, SKULabs adds up item weight × quantity. If some items have no weight, the store's default weight is used (or the partial total, whichever is greater).
Dimensions: if the order is exactly one kit, or a single item, with dimensions set, those dimensions are used.
Store defaults. Anything still empty is filled from the store's default weight and dimensions (store settings > shipping defaults).
Shipping rules always run last and can override all of the above:
Set weight replaces the weight.
Set box fills in the saved box's dimensions and adds the box's weight to the current weight.
Choosing a saved box by hand works the same way: its dimensions are filled in and its weight is added. If you switch to a different box, the previous box's weight is removed first, so box weights don't stack.
Tip: to get the most accurate weights, set weights on all items (and on kits you ship on their own), give saved boxes a weight, and leave Memorize on so repeat orders fill in automatically.
Add customs information to items
When shipping internationally, let SKULabs fill out the customs form for you.
Add saved boxes
Add custom saved boxes to easily track packaging materials and quickly enter or automate setting shipping dimensions.
Go to Settings > Shipping > saved packaging / boxes.
Click Add box, then set a nickname, location, dimensions, and weight. The box weight is added to the shipment weight whenever the box is selected.
To track inventory for your packaging, create a new item with a SKU in the following format matching your saved box dimensions and assign it to a warehouse location:
Box (12x12x12 in), Box (30x30x30 cm), etc.
Enable/disable shipping methods
You can permanently hide or show specific rates like Media Mail and Library Mail on the Enabled methods page (Settings > Shipping > Enabled methods).
Only active methods are considered when using the "Least expensive" shipping options and shown for selection when shipping. To exclude a method, uncheck the box in the Active column next to it and click Save. Check the box again to bring it back.
Set up shipping rules
Custom shipping rules can automate decisions based on criteria like specific SKUs or tags, value, weight, or number of items and help group similar orders for quicker fulfillment.
Shipping rules can also be configured to set default shipping methods, especially if more than one criteria beyond an exact match of the requested method is needed.
Set up shipping method links
Use shipping method links to automatically suggest a specific shipping method when creating labels based on the shipping option a customer chooses on your store at checkout.
