# The checkout order-notes field: does it cost conversions? - Checkout Optimize Lab

The order-notes field costs a small but measurable share of completions on mobile, where it adds scrolling and cognitive load. Keep it when a real share of orders needs the information; collapse it when they do not; and never let it sit open and empty on the payment step.

The order-notes field is the appendix of checkout: a small box, usually labeled delivery instructions or order notes, that most shoppers ignore and some stores cannot live without. It looks harmless. The evidence says it carries a cost, concentrated exactly where checkout is most fragile.

The cost is not the field itself. It is what the field signals and the space it takes. An open text box asks the shopper to think, and thinking is the enemy of momentum. On mobile, it also pushes the payment button further down the screen, which is a tax every shopper pays whether they use the field or not.

## What the field is actually for

Order notes serve three legitimate jobs. Delivery instructions for tricky addresses: gate codes, leave-with-neighbor, do not ring the bell. Gift messages and wrapping requests for the gifting segment. And product customization details that did not fit anywhere else: engraving text, monogram choices, dietary notes for food brands.

Notice what these have in common: they matter to a minority of orders. For most stores, under 15 percent of checkouts include any note at all. The question is never whether the field is useful in the abstract. It is whether the 15 percent justifies the friction imposed on the other 85.

## Where the friction shows up

The measurable cost is small per shopper and large in aggregate. Form analytics consistently show the notes field adding seconds to the step and a small uptick in abandonment at the payment stage, concentrated on mobile. The mechanism is partly visual: an empty text box reads as an unanswered question, and some shoppers pause to decide whether it is required, even when it is clearly optional.

There is also a support cost hiding in the field. Shoppers put things in order notes that no one reads in time: address corrections after submission, cancellation requests, allergy information. Every note that arrives too late or goes to the wrong team is a support ticket the field created. If your notes are full of requests your fulfillment flow cannot act on, the field is generating work, not information.

## The middle path: collapse it

The best answer for most stores is neither kill nor keep open. Collapse the field behind a link: add delivery instructions or add a gift message. The shoppers who need it will find it; the shoppers who do not will never see it. The payment button moves up, the visual noise drops, and the 15 percent keeps their channel.

Context beats a generic box. If most of your notes are delivery instructions, label it delivery instructions and place it on the shipping step, not the payment step. If most are gift messages, show it only when the cart contains a gift wrap option or when the shipping address differs from billing. A field that appears for a reason converts better than a field that appears always.

## Measure before you decide

Pull your own numbers before changing anything. What share of orders include a note, what share of those notes contain actionable information, and how does completion differ between sessions that interact with the field and sessions that do not. If the field is genuinely load-bearing for your fulfillment, keep it and optimize around it. If it is decorative, collapse it and watch the payment step breathe.

Should the order-notes field be on the cart page instead?
:   Often yes. The cart page has more room and less momentum at stake, and notes entered there carry through to checkout. Moving the field upstream removes it from the payment step entirely, which is where its cost concentrates.

Does removing order notes hurt gift orders?
:   Only if you remove the capability instead of relocating it. Gift messages tied to a gift wrap option, or shown when shipping and billing addresses differ, serve gift buyers better than a generic box because they appear exactly when relevant.
