Orders & fulfilment

What Flare writes on your orders

Updated 23 July 2026

Every scheduled order carries its dates in three forms — tags, attributes, and metafields — so your team, your searches, and your other tools can all read the promise.

Tags

Tag	Example	Meaning
Delivery date	`Delivery on Jan 15 2025`	The date the customer chose
Ship date	`Ships on Jan 13 2025`	The dispatch date Flare calculated
Pickup date	`Pickup on Jan 15 2025`	For pickup orders, plus a `pickup` tag and a location tag
`Flare`	`Flare`	Marks the order as scheduled by Flare
`Ready to Ship`	—	Added when the order comes within your dispatch window (see hold & release)

Tags make Shopify's order list filterable by date: the dashboard's View all scheduled orders / View unfulfilled / View orders ready to ship links are exactly these tag filters.

Customise the formats

Shipping settings → Order attributes and tags → Customize:

Tag wording — change the prefix ("Delivery on", "Ship:", or none) and the date format per tag type.
Attribute date format — ISO 2025-01-15 (default), US 01/15/2025, UK 15/01/2025, Jan 15, 2025, and more.

Changing formats is safe mid-flight — Flare reads both old and new formats on existing orders.

Order attributes

Order-level attributes carry the machine-readable values:

__flare_delivery_date, __flare_ship_date, __flare_time_slot
Shipping context when zones are on (zone and shipping option names)

You can rename the delivery/ship keys to custom attribute keys if another system expects specific names. These attributes power the order confirmation email snippet and the thank-you/order-status displays. Product/cart page setups also write a line-item property (default label "Estimated Delivery") visible on the order's line items.

Shopify "Fulfill by"

Flare writes the ship date into Shopify's native Fulfill by field on the fulfilment order, so the deadline shows in Shopify's own order list with no extra apps. On by default; turn off Sync ship date to Shopify Fulfill by (Shipping settings → Fulfillment settings) if another integration owns that field.

Using it all in Shopify Flow and other apps

Because dates are ordinary tags and attributes, anything that reads orders can act on them:

Shopify Flow: route rush orders ("tag contains today's ship tag"), notify a channel, add fulfilment holds of your own.
Flow trigger: Flare fires a "delivery date changed" trigger when a customer reschedules — build "notify the kitchen" automations on it. See self-serve rescheduling.
3PLs/OMS: ShipStation gets first-class sync (guide); anything else can key off tags, attributes, metafields, or Fulfill by.
