Mulligan installs in your Shopify admin and runs on your customers’ order pages. Here’s the path from install to your first self-served edit.
1. Install the app
Add Mulligan from the Shopify App Store. During install you’ll approve the permissions Mulligan needs to read and edit orders, issue refunds, and place fulfillment holds on your behalf. Your 7-day free trial starts here — see Billing.
2. Run the setup checklist
On first open, Mulligan shows a short setup checklist. It walks you through:
- choosing which edits customers may make,
- setting the editing time window,
- confirming your refund preferences (original payment or store credit), and
- optionally connecting ChannelDock and address validation.
You don’t have to enable everything at once — start with the edits you’re most comfortable with and add more later.
3. Choose your first edits
We recommend starting with the big three, since they cover most real “change my order” requests:
- Shipping address — fixes wrong addresses before they ship.
- Cancel / reduce items — handles the “I ordered twice” emails automatically.
- Add items — lets customers top up an order before it leaves.
Each one has its own safety rails, covered in Editing features and Settings.
4. Test it on a real order
Place a test order on your store, open the order-status or order page, and make an edit as a customer would. Confirm the refund or invoice behaves the way you expect before you rely on it.
Tip: the editing time window defaults to 1 hour. About 95% of order changes happen in the first 30 minutes after checkout, so a short window usually covers real needs while keeping you safe.
