Can a fee or shipping rule end on a date?

Yes: the newest version of a payment fee rule or a logistics rule can be given an end date, in its Effective to field. Leave it as Ongoing and the rule keeps running until you change it.

After the end date the rule prices nothing. Payments by a method whose rule has ended fall back to what applies without a rule: the fee Shopify reports on a Shopify Payments payment, or your Other rule if you keep one, and with neither the method is flagged as unpriced. A shipping rate card that ends with no new one after it leaves later parcels without a carrier cost, and the Overview flags it, “No shipping price since” with the date, so a gap never reads as free shipping. Pick and pack, packaging, return processing and packaging EPR simply stop.

Use it when a cost really stops: you leave a carrier, a warehouse or a payment provider. When only the price changes, add a new version with its own effective-from date instead, and the old version closes by itself.

Only the newest version takes an end date of your choosing. An older version always ends the day before the next version starts, and that date is set for you. Editing an older version without changing its Effective from changes only that version. Saving with another Effective from applies the values from that date forward and replaces every version that starts on or after it, and the panel names those versions before you save. Either way, every order is priced by the version that applied on its own day, and the days from the change on are recalculated.
