How to send a unique invoice per fulfilment for multi fulfilment orders

Shopify Discussion

Topic summary

A merchant needs to send unique PDF invoices for each individual fulfillment in multi-fulfillment orders (often 10+ shipments per order). Currently, Shopify’s shipping confirmation email lacks Liquid variables like fulfillment.id or fulfillment.name to identify which specific fulfillment triggered the notification.

The Problem:

  • Without unique fulfillment identifiers, dynamically generating fulfillment-specific documents is impossible
  • Merchants are forced to send one merged PDF covering all fulfillments
  • This creates customer confusion with partial shipments

Proposed Workarounds:

  • Store fulfillment IDs as order metafields, then reference those metafields in email notifications
  • Use automation tools like the Mechanic app to create custom fulfillment workflows and PDF generation
  • Example tasks available at tasks.mechanic.dev

Status: The native Shopify feature doesn’t exist; the discussion remains open with workaround suggestions but no confirmed solution implemented.

Trying to send fulfillment-specific PDF invoices via the standard Shopify shipping confirmation email.

Right now, there’s no unique Liquid variable for fulfillment.id, fulfillment.name, or any other identifying reference that would let us isolate which specific fulfillment triggered the email.

Because of that, we can’t dynamically generate or link to fulfillment-specific documents — we’re stuck sending one merged PDF for all fulfillments, which causes confusion for customers receiving partial shipments. We freuqently have 10+ fulfilments for an order

does anyone know of anyway that this can be done?

Ideally i assume this would be exposed as fulfillment.id (or any unique identifier) within the shipping confirmation notification’s Liquid context?

This would unlock:

Reliable per-fulfillment documents

Cleaner customer communication for multi-shipment orders. But this feature doesn’t appear to exist? Surely there’s a workaround somewhere?

Keen on everyone’s thoughts.

Hi @Sam1029039 :waving_hand: If a property isn’t available it has to be worked around

variables reference https://help.shopify.com/en/manual/fulfillment/setup/notifications/email-variables

Try storing the fulfillment ids on the order as metafields then reference the metafields in notifications.

Or use an automation tool like the mechanic app to do it custom and take control of the process.
