Ulmod – Order Comments Extension

Review of Checkout Order Comments Magento 2 Extension for User Feedback

Summary

Key takeaways

Checkout Order Comments (Ulmod) adds an order comment field at Magento 2 checkout so customers can leave delivery notes, product clarifications, or questions for support.
The comment field size can be configured, making it easier to fit different checkout layouts and UX needs.
You can set a character limit to keep messages concise and prevent overly long notes.
Customer comments can be included in the order confirmation email so shoppers see their note was recorded.
The feature improves customer experience by reducing delivery misunderstandings and back-and-forth after purchase.
It’s a lightweight “checkout UX” enhancement that can support operational accuracy (shipping, picking, courier instructions).
The extension is free to download, with paid options to extend support duration and optional paid installation.

When this applies

Use this when customers frequently need to add delivery instructions (time windows, access notes), gift notes, order packing requests, or quick clarifications at checkout—and your team wants those notes captured directly on the order and visible in admin/email workflows.

When this does not apply

Skip this if your checkout already captures structured delivery options (delivery slots, pickup instructions) or you need complex note logic (conditional fields, multiple note types, file uploads, per-item notes). In those cases, a custom solution or a more advanced checkout customization is a better fit.

Checklist

Identify which checkout step should display the comment field (shipping, payment, review).
Decide what the comment is for (delivery instructions, packing notes, customer questions, internal reference).
Set a reasonable character limit (enough for instructions, not enough for essays).
Configure the field size so it doesn’t disrupt the checkout layout (desktop + mobile).
Confirm the comment is saved to the order record and visible to admin users.
Ensure the comment appears where your ops team works (order view, packing flow, shipment creation).
Enable inclusion in the order confirmation email if you want customer visibility and fewer disputes.
Confirm the comment is accessible in exports/integrations if your fulfillment is external.
Test with different checkout scenarios (guest vs logged-in, different shipping methods, coupons).
Validate the field doesn’t break one-step checkout or custom checkout themes/modules.
Add internal guidelines for staff on how to interpret and act on notes (what’s actionable vs informational).
Monitor support tickets for 2–4 weeks to see if delivery-related issues decrease.
If needed, define moderation rules (e.g., filter profanity, block sensitive data, trim whitespace).
Plan a fallback: if the module doesn’t fit, define requirements for a custom extension.

Common pitfalls

Setting the character limit too low, forcing customers to abbreviate critical delivery details.
Allowing unlimited text and ending up with unstructured, noisy notes that ops teams ignore.
Forgetting to surface the comment in the right backend workflow, so it gets missed during fulfillment.
Conflicts with custom checkout modules or one-step checkout implementations that remove/override fields.
Treating comments as a substitute for structured delivery options (time slots, pickup points, address validation).
Not clarifying internally what types of requests are acceptable, leading to inconsistent handling.
Collecting sensitive info unintentionally (payment details, personal data) without guardrails.

Checkout Order Comments is an extension developed by Ulmod. With its help, your customers can comment about the delivery, your products, or ask a question to your customer support representatives.

Why do you need Order Comments?
