Start selling online: the label checklist

Set up a repeatable order-to-parcel routine before your first busy week.

Choose one packing area, keep the printer and paper within reach, and prepare a simple checklist: confirm the order, verify the delivery address, pick the right package, print the platform-approved carrier label, and record the tracking number. A reliable routine matters more than buying lots of equipment on day one.

Begin with the order volume you have now. Test one package from checkout to printed label, then adjust the steps that cause delays. Keep customer information private and clear the print queue after shared-device sessions.

Shipping labels and packing slips: what each one does

Know which sheet belongs on the parcel and which one belongs inside.

A shipping label identifies the parcel for the carrier and normally includes a route or service barcode. A packing slip summarizes what is inside the order for the seller and customer. They can be printed together in one workflow, but they serve different purposes.

Use the postage label supplied by your carrier or selling platform for an actual shipment. Add a packing slip when it helps with picking, returns, or customer support. Never place two competing carrier labels on the same package.

How to check a delivery address before printing

Catch missing apartment numbers, postal codes, and country details early.

Read the recipient name, street, building or apartment, city, region, postal code, and country as one complete address. International addresses can use a different order from the one you are used to, so preserve the recipient’s local format.

If a required field is missing or the address looks inconsistent, ask the customer or use the platform’s address validation before buying postage. Do not guess a postal code. A small check before printing can prevent a return or redelivery charge.

Pick a printer for a small online shop

Compare thermal and inkjet printing by volume, space, and label stock.

Thermal printers avoid ink cartridges and are convenient for frequent shipping labels. Standard inkjet or laser printers can work well when you print occasional labels on compatible sheets. Compare the device’s supported label widths, driver availability, and connection options before buying.

Check the printer manufacturer’s specifications and test the exact stock you plan to use. A clear barcode and correct dimensions matter more than an impressive speed claim. A phone-friendly wireless setup may also save space in a small packing area.

Print a 4 × 6 shipping label at the correct size

Use actual-size printing so the barcode and address stay readable.

A common parcel label layout is 4 × 6 inches. In the print dialog, select the matching media size and use Actual size or 100% scaling. “Fit to page” can shrink the barcode or move content toward the edges.

Print a test on plain paper first if you are setting up a new printer. Compare it with the preview, check that the full label is visible, and scan the barcode if you have access to a scanner. Keep the label flat and fully attached to the parcel.

Set label spacing and margins for cleaner prints

Prevent crowded addresses and clipped lines with a simple test routine.

Leave enough space between the recipient name, street lines, city and postal code. Keep the barcode clear of text, folds, tape seams, and the edge of the label. Use one clear typeface and a visible hierarchy instead of shrinking every line to fit.

Printer margins vary by device and stock. Print a test, inspect all four edges, and adjust the layout in small steps. Do not compensate for a printer scaling issue by squeezing the recipient details until they become hard to read.

07Label printing

Choose label paper that matches your printer

Match adhesive stock, size, and finish to the way you pack.

Direct thermal printers need compatible thermal label rolls or fanfold stock. Inkjet and laser printers need sheets made for the corresponding print technology. Check adhesive strength, core size, roll width, and the printer’s maximum media thickness.

Store labels away from heat, dampness, and direct sun. Before committing to a large supply, test a small pack through your full print-and-apply routine. A label that curls or smears at the packing table can slow down dispatch.

Print a packing slip and shipping label together

Build a two-page or combined-sheet workflow that is easy to pick and pack.

A packing slip helps match products to an order; the carrier label routes the parcel. Some seller platforms let you print both in one session. If you make a combined sheet, give each section a distinct title and make sure the carrier barcode is not mistaken for an internal SKU barcode.

Keep the slip inside the parcel or in the pouch intended for documents. Put the carrier label on the outside, on a flat surface. Always use the platform or carrier-issued label for postage and tracking.

Design a readable return label

Make return instructions easy to spot without confusing them with outbound postage.

A return information label can show an RMA or order reference, the return destination, and concise packing instructions. Use a strong heading and leave room for the customer’s details when the seller needs them. Keep outbound and return directions visibly separate.

A printable design by itself does not pay for postage or activate tracking. If you offer prepaid returns, generate the actual return label through the carrier or marketplace account and share its current instructions with the customer.

EAN-13 and UPC-A: product barcode basics

Understand common retail barcode formats before preparing product stickers.

EAN-13 and UPC-A are retail trade-item barcode formats. The correct number depends on the product, market, and retailer requirements. A barcode graphic is only the visual encoding of an identifier; it does not grant ownership of a valid product number.

Obtain and manage product identifiers through the relevant GS1 organization or the channel’s approved process. Test the printed symbol at the final size and confirm the digits below it match the assigned number exactly.

What a SKU does for a small seller

Use a consistent internal code to find, pick, and count products.

A SKU is an internal reference chosen by a business. It can describe a product family, size, color, or storage location when the naming rules stay consistent. Unlike a carrier tracking number or retail GTIN, a SKU is usually meant for your own inventory workflow.

Choose a short pattern that staff can read and enter reliably. Avoid reusing a code for a different product after sales history exists. Put the SKU on a product or warehouse label where it helps picking, but keep customer-facing labels uncluttered.

Make a barcode easier to scan

Protect contrast, quiet space, size, and print quality around the symbol.

Barcodes need a clean contrast between bars and background and enough clear space around the symbol. Very small prints, low-resolution output, glossy glare, wrinkles, and ink smearing can all make scanning harder. Do not cover the symbol with tape that reflects light.

Test with the scanner and software used in your actual workflow. Verify both the scanned value and the printed human-readable digits. Use the barcode format required by your carrier, retailer, or inventory system rather than assuming all scanners accept the same format.

Inventory labels for bins and shelves

Make location names consistent so every item has a predictable home.

A useful location label can combine an aisle, bay, shelf, and bin code such as A-03-02. Keep the sequence consistent across the building and make the largest part of the label the part workers need to read from a distance.

Start with one zone, document the naming rule, and label both the physical location and the inventory record. If you add a barcode, encode the exact location ID your inventory software expects. A tidy location map makes cycle counts and order picking more repeatable.

eBay postage labels and packing slips

Separate marketplace postage from the documents you design yourself.

When an order is eligible, eBay sellers can purchase or create a shipping label from the order workflow. Tracking is associated with that shipment through the account process. A packing slip can help organize the item and reference, but it is not a substitute for eBay postage.

Check the order’s delivery service and address in the seller account before buying a label. For a return, follow the return request shown in eBay. If an order needs a QR drop-off option, use the QR code provided by the platform or carrier; do not replace it with a home-made barcode.

Temu seller shipping: where the label comes from

Use the seller workflow for the current order and fulfillment option.

Temu’s seller shipping options can vary by region, order, and fulfillment setup. When Temu provides a shipping label for an eligible order, generate and download it from the seller workflow attached to that order. Keep the order ID, parcel, and tracking details together.

A separate design tool can prepare a packing slip or internal warehouse sticker, but it cannot create a valid Temu postage purchase without an authorized integration. Check the current Seller Center instructions for package limits, handoff steps, and tracking updates before dispatch.

Amazon FBA carton labels: print the assigned ID

Keep the marketplace’s box ID tied to the exact inbound shipment.

For an FBA inbound shipment, follow the current shipment plan and print the box labels Amazon assigns. The box identifier relates to a particular shipment and box; a generic label design cannot invent or replace it. Match each printed label to the carton listed in the plan.

Use the carrier label and box ID label required by the shipment workflow, and place them where they can be scanned without crossing a seam. If the plan changes, regenerate labels from the account rather than reusing an old box ID.

Packing slips for Shopify, eBay, and Temu orders

Make one neutral packing slip that can work across order channels.

A marketplace-neutral packing slip can show an order reference, the recipient, item description, SKU, quantity, and seller contact details. It helps with picking and customer service without pretending to be the carrier’s label. Keep fields optional where marketplaces supply different data.

Print the slip from your order system when available so the information is current. If you design a general template, compare it with each channel’s packing rules and remove fields that should not be shared with the buyer. Store only the order details your workflow needs.

Customs forms: describe goods clearly

Use a specific, accurate contents description and value.

Cross-border shipments may need customs information such as a plain-language item description, quantity, value, weight, origin, and tariff classification. The details should match the parcel and the seller’s records. Vague descriptions can delay review or cause a correction request.

Use the postal or carrier system required for the destination and service. Some customs data must be sent electronically and some forms have strict official layouts. A printable draft is not evidence that a declaration has been filed or accepted.

Lithium battery labels need shipment-specific checks

Do not rely on a generic warning sticker to determine whether a parcel can travel.

Battery transport requirements depend on chemistry, configuration, battery quantity, watt-hour rating, packaging, and the route. A warning label is only one possible marking; it does not make a shipment compliant by itself.

Before dispatch, check the current carrier and applicable dangerous-goods rules for the exact battery and service. Use the carrier’s required documentation and packaging. If the shipment is regulated, ask a qualified shipping or compliance contact to review it.

UN numbers and dangerous-goods marks

Treat hazard labels as regulated markings, not decorative stickers.

UN numbers identify particular dangerous goods in transport rules. The correct marking depends on the substance, its classification, packaging, quantity, and applicable mode of transport. A label preview can help with layout planning, but a wrong or incomplete mark may create serious delays and safety risks.

Confirm classification and required wording with current official rules and the carrier before shipping. Use approved label stock and exact specifications where required. Do not use a generic template as a certification or assume a similar-looking diamond is compliant.

Cold-chain labels: add handling details people can act on

Make the required temperature range and handoff instruction easy to see.

A cold-chain handling label should clearly show the temperature range or storage instruction defined for the product. It can also include a shipment reference and a concise action such as “keep refrigerated.” The correct range must come from the product owner or shipping procedure.

A paper sticker cannot measure or control temperature. Use suitable packaging and any required temperature logger, and record handoffs when your process calls for it. Confirm carrier acceptance for the service before sending temperature-sensitive goods.

A better fragile parcel starts inside the box

Use cushioning and movement control; a sticker alone cannot protect an item.

Choose a box that fits the item and cushioning. Fill empty space so the contents do not shift, protect corners and delicate surfaces, and close the package with tape suited to its weight. A “fragile” label can alert handlers, but it cannot replace sound packing.

Test packaging for the likely journey and follow the carrier’s packaging guidance. Place warning labels where they are visible and keep them away from barcodes and address fields. Take a quick photo of unusual or high-value packing for your internal records.

Heavy parcel handling and safe lifting

Make weight and team-lift instructions visible to the people moving the box.

A handling label can call attention to a heavy or awkward parcel, but safe movement depends on known weight, clear routes, and suitable lifting equipment. Put the weight where staff can see it and follow workplace lifting procedures.

Use a box and closure rated for the contents and route. Do not hide a heavy parcel’s weight behind decorative branding. Where the carrier has a specific weight marking or booking rule, follow that requirement and declare the accurate shipment weight.

Tamper-evident seals: what they can and cannot prove

Use seals to show visible opening, while keeping chain-of-custody records.

A void or tamper-evident seal can make opening more visible when it is applied across a closure. It may support a packing routine, but it does not prove who opened a parcel or guarantee that contents were untouched. Choose a seal suited to the surface and temperature.

Record seal numbers for sensitive items and pair them with an order or shipment reference. If a seal is damaged on arrival, photograph it and follow the seller’s incident process. Do not describe a basic sticker as a security guarantee.

Sustainable packing without losing protection

Reduce unnecessary materials while keeping the product safe in transit.

Right-size the box, reuse clean protective materials where appropriate, and avoid adding inserts the customer does not need. A lighter, compact parcel may be easier to handle, but the product still needs enough protection for its route and fragility.

Check destination recycling guidance before printing disposal claims on packaging. Keep shipping labels legible and avoid covering required safety or customs details with a sustainability message. Track damage and return rates as you test a new packing approach.
