- Short answer
- No — return rule changes apply only to future orders; orders already placed keep the rules that were in force when they were placed.
- Which orders return rules cover
- Return rules apply to all orders, including B2B; you can't set separate rules by order type
- How an old order is judged
- Only the POS Pro return-rules page we found says rules are saved to the order when placed
- Self-serve switched off
- Rules still apply — restocking fees hold when you process a return manually from the Shopify admin; fees stay editable
- The POS Pro override
- POS Pro staff can accept an ineligible return and log a reason; permission or manager approval needed
- Where Shopify states it
- In a Note under Final sale items on the return-rules page; the POS Pro page repeats it in plain prose
Does changing a return rule affect orders you already have?
No — Shopify states it in a Note at the end of the Final sale items section of its return-rules page:
Changes to your return rules apply only to future orders. Changes don't apply to previous orders, so that they don't impact customers who've already placed an order.
The same page goes wider: return rules apply to all orders, including B2B orders, and you can't set separate return rules by order type. No page of the returns documentation we read on August 8, 2026 — the Returns and exchanges index and the five pages under it — gives this its own heading.
What rules does an order already placed keep?
The ones it was placed under. Only one page we found names the mechanism — Shopify's return rules page for Shopify POS Pro, which states that return rules are saved to the order at the time the order is placed; the general online page promises the same outcome without naming the mechanism. So a rule you change today does not re-judge yesterday's returns: that order carries the older window and the older restocking fee. Which values to set is covered in returns and cancellations.
Can you apply the new rule to an order you already have?
Not by editing your rules — a rule change never reaches an order already placed. Shopify states you don't need self-serve returns and cancellations activated for rules such as restocking fees to apply when you process returns manually from the admin, and that return rules still apply then. Doing it yourself changes who starts the return, not which rules govern it. What you can still change is the money on one return: Shopify says you can edit the return shipping fee for a specific return, and the restocking fee, including by item; when you create the refund, you need to manually deduct any applicable return fees. Shopify's POS Pro page documents an override: at Shopify POS Pro locations staff can accept a return that doesn't correspond to your store's return rules and log a return reason to document the exception — with the Return ineligible items permission or a manager's approval.
