Can I change the size on my order after I place it?

Usually yes, until it ships. After that, the size change becomes an exchange under the store's return policy.

How does a store swap a variant on a Shopify order?

By editing the order: remove the old size or colour and add the new one. If the price differs, the store invoices or refunds the difference.

Can Aide swap the size itself?

No. Aide confirms there is stock in the size they want and passes the swap to your team. If the customer would rather reorder, Aide can take the unshipped item off the order.

What if the new size is out of stock?

Say so, offer the nearest size or colour you have, or remove the item, with its refund waiting for approval.

Short answer

When a customer ordered the wrong size or colour, it can usually be swapped until the order ships. Check the new variant is in stock, confirm the swap only once the order shows it, and offer an exchange instead if it has already left.

I ordered the rain jacket in medium on #1063 but I need a large. Can you change it?

Perfect, thank you.
