A customer wants their gift wrapped. Another needs the box left at the back door. A third is buying for a friend and wants a handwritten card inside.
If your Shopify cart drawer doesn’t have an order notes box, all three of those people just hit “checkout” with their fingers crossed. Some of them won’t come back if you get it wrong.
This guide shows you the fastest way to add order notes to your Shopify cart drawer, what to write in the prompt so people actually use it, and the small mistakes that quietly cost stores money every week.
What Are Shopify Order Notes?
An order note is a text box where your customer can leave a message before they check out. The note shows up on the order in your Shopify admin so you (or your packing team) can read it before shipping.
Three things on Shopify look similar but do different jobs:
- Order notes — one message for the whole order (like “leave at side gate”)
- Cart attributes — custom fields you control (like a dropdown for delivery date)
- Line item properties — notes attached to one product (like engraving text)
This guide is about order notes inside the cart drawer (the slide-out cart that appears when someone clicks the cart icon). If you’re still deciding between a cart page and a drawer, our breakdown of cart drawer vs cart page covers which one converts better for most stores.
Why Order Notes Matter More Than People Think
Most store owners treat order notes as a “nice to have.” That’s a mistake.
A short note field does three quiet things for your store:
- Cuts support tickets. People ask their question in the cart instead of emailing you after they’ve paid.
- Reduces refunds and returns. Special instructions get followed because they’re written down, not buried in a chat.
- Builds trust. A buyer who can leave a note feels heard. That’s a small thing, but small things stack up.
One small jewelry brand we know added an order notes box to their cart drawer and saw their “wrong delivery instructions” emails drop by more than half in the first month. They didn’t change anything else.
Method 1: Turn On Order Notes in Your Shopify Theme (Free, 2 Minutes)
Most modern free Shopify themes (Dawn, Sense, Refresh, Craft, and others) already have order notes built in. You just need to switch them on.
Here’s how:
- Go to Online Store → Themes in your Shopify admin
- Click Customize on your live theme
- Open the top dropdown and pick Cart
- Click the Cart drawer or Subtotal block
- Check the box that says Enable cart note (or Show cart note)
- Click Save
That’s it. Open your store in a new tab, add a product, click the cart icon, and you should see the note field.
Heads-up: If your theme is set to “Page” instead of “Drawer,” the toggle may only show notes on the cart page. Switch the cart type to “Drawer” first under Theme settings → Cart.
Editing the Default Label
The default label is usually “Order special instructions.” That’s boring and people scroll past it.
To change it:
- Go to Online Store → Themes
- Click the … (three dots) next to your theme → Edit default theme content
- Search for special instructions in the filter box
- Replace the text with something specific (more on what to write below)
- Save
Method 2: Add Order Notes With a Cart Drawer App (The Way Most Stores Do It)
Theme-level notes work, but they’re stuck where the theme puts them. You can’t move the box, edit the placement on mobile, or pair it with upsells, free gifts, and a free shipping bar in the same drawer.
That’s why most growth-focused Shopify stores use a cart drawer app. You get order notes plus full conversion tools in one place — no stacking five apps for one cart.
Setting Up Order Notes in Oxify Cart Drawer & Upsells
If you’re using Oxify Cart Drawer & Upsells, turning on order notes takes about 30 seconds.
Here’s the exact path:
- Open the Oxify app from your Shopify admin
- Go to Cart Edit (the cart drawer designer)
- Find the Additional Notes block in the left panel
- Click Enable — the toggle turns green
- Set the Notes Title (e.g. “Add a note to your order”)
- Set the Notes Placeholder (e.g. “Special instructions for your order”)
- Pick Notes Placement — top of checkout block, above subtotal, or collapsed at the bottom
- Optional: tick Open notes section initially if you want the field expanded by default
You can also style the title size and arrow icon color to match your theme, and add translations for multi-language stores.
The note field shows up live in the cart drawer preview on the right side of the editor, so you can see exactly what shoppers will see before you save.
What Else You Get in the Same Drawer
Order notes alone won’t move the needle. The reason most merchants pick a full-funnel cart drawer is what sits next to the note box:
- A free shipping progress bar that nudges customers to add one more item
- A free gift unlock at a spend threshold
- Cart upsells and frequently bought together suggestions
- A discount code box without redirecting to checkout
- Trust badges and a countdown timer to reduce drop-off

Method 3: Add Order Notes With Code (For Custom Themes)
If you’re on a custom or older theme that doesn’t have a notes toggle, you can add it manually. You’ll need light Liquid knowledge.
Open your cart-drawer.liquid file (or whatever your theme calls the drawer file) and paste this inside the cart form, just above the checkout button:
<label for="CartNote">Add a note for your order</label>
<textarea name="note" id="CartNote">{{ cart.note }}</textarea>
Two rules to follow:
- Keep
name="note"exactly as written. Shopify uses that to save the message. - Place it inside the
<form>tag, not outside.
Save the file, refresh your store, and test by adding a product and typing a note. Then check the order in your admin to make sure it came through.
What to Write in the Note Prompt (This Is Where Most Stores Mess Up)
The default “Order special instructions” tells your buyer nothing. They don’t know what to write, so they write nothing.
Give them a real reason to use the box. Match the prompt to your product:
- Florist: “Tell us what to write on the card”
- Bakery: “Any allergies or special requests?”
- Apparel: “Gift? We’ll skip the receipt — just let us know”
- Pet store: “Tell us your pet’s name — we’ll add a sticker”
- Furniture: “Delivery notes (gate code, parking, floor)”
- Jewelry: “Engraving text or a message for the gift card”
- Beauty/skincare: “Any allergies or skin concerns we should know?”
- Gift store: “Gift message? We’ll handwrite it”
A specific prompt gets used. A generic one gets ignored.
If gift messages come up a lot in your store, you might also want to add a real gift wrap option instead of relying on the note box alone.
How to Read Order Notes After They Come In
Notes show up in two places:
- On the order page in your Shopify admin, under the Notes section on the right
- On the order printout if your packing slip template includes the
{{ order.note }}tag
If your team uses ShipStation, ShipBob, or another fulfillment tool, double-check that order notes are pulling through. Some tools hide them under a “customer note” or “instructions” field — train your packers to check it before they tape the box shut.
5 Small Mistakes That Hurt Conversions
After looking at hundreds of cart drawers, these are the slip-ups we see most:
- The note box is below the checkout button. Move it above. People click checkout the second they see it.
- The label is “Notes.” Too vague. Tell them what to write.
- The box is huge and empty. A giant textarea looks like homework. Keep it 2–3 lines tall.
- No character limit shown. Some buyers worry they’ll write “too much.” Add a small “(up to 250 characters)” hint.
- No mobile testing. On phones, a poorly placed note field can push the checkout button below the fold. Test on a real phone, not just the preview.
A messy note field is one of many small UX problems that quietly increase drop-off. If you’re seeing high cart abandonment, our guide on reducing cart abandonment with a better cart drawer goes deeper into the fixes that actually move conversion.
Order Notes vs. Cart Attributes: Which Should You Use?
Quick rule:
- Use order notes when one free-text message is enough (gift messages, delivery instructions, allergies)
- Use cart attributes when you need structured answers (a dropdown for delivery date, a checkbox for gift wrap, a required field for B2B PO numbers)
Most stores only need order notes. If you find yourself parsing the same kind of info from notes again and again, that’s the signal to upgrade to a cart attribute.
Slide Cart vs. Mini Cart: Does It Matter for Notes?
Both can hold a notes field, but they behave differently. A slide cart gives you more space (and more conversion real estate), while a mini cart is tighter and cleaner. We compared the two side-by-side in our slide cart vs mini cart breakdown — short version: slide cart wins for stores that want order notes plus upsells in the same view.
Frequently Asked Questions
Do order notes work at checkout, or only in the cart drawer?
They’re set in the cart (drawer or page) and submitted with the order. They don’t show on the checkout itself unless you add them as a checkout extension.
Can customers edit their note after checkout?
No. Once the order is placed, the note is locked. They’d need to message you to update it.
Will order notes work with Shop Pay and Apple Pay express checkout?
Express checkout buttons skip the cart, so the note field has to be filled before the buyer taps Apple Pay or Shop Pay. Place the note above the express buttons so it’s seen first.
Are order notes saved if a customer leaves and comes back?
Yes, as long as their cart cookie is still active. If they clear cookies or come back days later, the note resets.
Do order notes affect SEO or page speed?
A native theme note field has zero SEO or speed impact. A poorly built app could slow your cart by a few hundred milliseconds — pick a Built for Shopify app to avoid that.
Can I make the order notes field required?
Not natively in most themes. You can mark it visually as required, but Shopify won’t block checkout if it’s empty. For required fields, use a cart attribute instead.
Get Your Cart Drawer Right the First Time
An order notes box is a five-minute setup. But the cart drawer around it is where most of your conversion work actually happens — upsells, free gifts, shipping bars, trust badges, and a clean mobile layout.
