Where Do I enter the weight of a product ordered for international shipments?

BorderGuru calculates the weights of your shipments by using the weight that you have assigned to your Item Data / Masterdata in shopify.

This means that the combined weights of the items in the cart of your customer at checkout determine the base for BorderGuru's shipping rate calculation. Because of this, it is important that the item weights are reasonably accurate in your shopify Masterdata.

You can either add / edit the weight of a single product in shopify directly through the product detail page on your store backend (see screenshot below), or you can use one of the mass-update functionalities and apps that are available for Shopify. If you have a larger item portfolio, the latter approach will save you significant amounts of time.

Please make sure that no product on your store has 0.0 as the listed weight. Weight is a mandatory factor for BorderGuru's shipping rate calculation, if this field is empty / has a zero value, BorderGuru will not be able to generate a shipping label for an order with this item on it.
