Did you find a solution to this please? We are having the same issue and it is driving me mad
Topic summary
Issue: Royal Mail Click & Drop pulls product weights from Shopify but does not add packaging (box + protective fill), causing label weights to be 50–250g under/over the actual parcel.
Current behavior and expectations:
- Users want pre-defined packages or an automatic way to include packaging weight before label generation.
- Shopify documentation allegedly claims “Default Package” weight is added to order weight, but users report it is not happening.
Conflicting information:
- One user shared a screenshot of Shopify support stating this is not a function; the Default Package only accounts for one packaging type.
- No clear confirmation from Royal Mail; users report difficulty getting a response.
Workarounds tried:
- Adding a small fixed weight (e.g., +5g) to each product in Shopify to approximate packaging, which underestimates single-item orders and overestimates multi-item orders.
Actions/next steps:
- A user plans to compile Shopify help docs citing the expected behavior and send them to Shopify support, encouraging others to do the same.
Status: Unresolved. No official fix or setting identified in Shopify or Click & Drop to reliably add variable packaging weights.
