Many sellers are beginning to realize that a printed packing slip is far more than just a piece of paper included with the shipment. A well-structured packing slip with an appropriate font size can significantly boost warehouse efficiency during picking and packing; displaying the brand logo and contact details reinforces brand recognition the moment customers open their packages; and a warm thank-you note or exclusive discount code can be the final push toward driving repeat purchases.



After trying out most mainstream print tools in the market, we found that none of them could strike the perfect balance between "highly customizable" and "user-friendly."



That was until we discovered 4Seller — a print system that supports multi-channel integration, logistics compatibility, and intuitive drag-and-drop WYSIWYG design. With it, custom printing finally becomes easy and accessible.

I. Why Add Personalized Content to Your Packing Slips? Customer Satisfaction and Warehouse Efficiency Depend on It
Packing slips are not just used to list product details; they sometimes double as invoices and are placed inside packages delivered to customers. Packing slips are a silent but powerful link between warehouse operations, post-sales service, and brand experience. A well-designed, clear, and standardized packing slip can streamline fulfillment while enhancing customer service and branding.



1. Improve Picking Speed with Accurate Item Matching
The basic function of a packing slip is to list the items included in an order—SKU, product name, quantity, and variant. With customizable fields like SKU, bin location, box number, and picker name, warehouse workers can pick orders more efficiently when the slip reflects the actual workflow.



2. Embed Post-Sale Info to Reduce Disputes
Including customer service email, return policy, and FAQs on the packing slip can effectively reduce complaints from customers who “can’t find support” or are “unclear about the return process.”



Sellers can add a note such as: "If you have any questions regarding your order, please contact us at support@example.com. We promise to respond within 24 hours." Adding a QR code for post-sale support also establishes a service touchpoint early, lowering the risk of negative feedback.


3. Reinforce Brand Identity and Enhance Customer Experience
Most packing slips are plain black-and-white documents. By adding your brand logo, social media handles, personalized messages, thank-you notes, or discount codes, your packing slip becomes a branded customer experience.



During the holiday season, you can include a note like, “Happy Holidays from [Your Brand],” along with your logo. Or add a promo like “Scan this QR code to follow our TikTok and get a discount on your next order.” Even a handwritten-style thank-you message like “Thanks for your support, your order means the world to us!” can increase brand affinity and drive repeat orders.


II. Why Mainstream Print Tools Fail to Offer True Customization


We’ve received constant feedback from sellers who are frustrated with rigid print systems. Some even offered up to $300 just to find a tool that could support fully customized packing slips.



After testing almost every major print tool on the market, we found that very few truly meet the need for high-level customization without coding expertise.


1. ShipStation: Powerful but Expensive and Code-Heavy
ShipStation is a leading tool in the U.S. for creating packing slips and shipping labels. It offers advanced features, but:



You must know HTML to create or modify ShipStation custom label templates.



There is no drag-and-drop interface.



Its plans aimed at high-volume sellers in the U.S. and Canada can be expensive.



For small and mid-sized sellers without a technical background, using ShipStation label document options or editing the ShipStation print label template PDF is very challenging.


2. Veeqo: Limited Field Options, No Custom Content
Veeqo offers basic packing slip template options but does not support free-text fields or flexible content editing:



Fields are fixed and include Size, Email, Billing address, Product Images, etc.



No option to add custom messages or marketing content.



This means that sellers using Veeqo cannot enrich their Veeqo shipping label template options with branded elements.


3. Shopify: Requires Advanced Coding and Third-Party Plugins


Shopify does not natively support packing slip customization. Sellers must use third-party apps like Order Printer, and:



Must edit Shopify custom shipping label templates using HTML, CSS, and Liquid.



No visual editor; templates must be coded or purchased.



Involves extra costs and a steep learning curve.



Shopify order printer edit HTML Liquid template methods are complex and not suited for non-technical users.


III. Is There a Tool That Offers Flexible Customization Without Code? We Found One.
Unlike the traditional ERP systems mentioned above, 4Seller delivers the best of both worlds: high-level customization with a low barrier to entry. No coding required—just drag and drop to design custom shipping labels, packing slips, and pick lists.



1. No Coding Needed: Drag-and-Drop Editor for Shipping Labels, Packing Slips, and Pick Lists





Compared to ShipStation create label without order or Shopify order printer which demand HTML or Liquid, 4Seller offers a fully visual interface. You can drag elements like SKU, customer address, order notes, brand logos, marketing messages, etc., directly onto your template.


This drastically lowers the learning curve and eliminates the need for coding skills. It also saves time on employee training and debugging print errors. Whether you're modifying the ShipStation print label template free or creating one from scratch, 4Seller is dramatically easier.



2. Highly Customizable Content for Branding and Customer Retention
4Seller allows sellers to print virtually any field or message on their slips—something ShipStation custom label templates and Veeqo add custom messages shipping labels simply cannot support.



You can add:

	
Brand logos
	
Thank-you notes
	
Discount codes
	
Customer service info
	
Return policies
	
Cross-selling recommendations
	
Social media promos



For example, a TikTok pet product seller might include: “Scan to join our pet community and get 10% off!”



This transforms the slip from a logistics tool into a powerful marketing asset.
