For Shopify & ecommerce brands
Your packaging, compared on what it really costs.
Mailers, custom boxes, inserts and shipping supplies get reordered every month, often from the first supplier you found. Dockline finds alternatives and compares them on delivered cost, minimums and lead time, so you can buy with confidence.
Free for one item you reorder regularly. No obligation to switch.
What we compare
The supplies every order ships with.
Branded packaging
Custom printed boxes, tissue, stickers and inserts. We compare setup costs, minimums and print options side by side.
Packing supplies
Labels, tape, void fill and other small items that add up across thousands of orders.
Also making the product itself? We can compare manufacturers for repeat production runs too.
Box sizing
A box that's slightly too big can cost you on every order.
Major carriers charge by a package's size as well as its weight. This is called dimensional weight. A light product in an oversized box can be billed as if it weighed more.
When we compare your packaging, we also look at whether a better-fitting box or mailer is available for your best-selling products. The goal is a clear picture of your options; you decide what to change.
- Fit. Boxes and mailers sized to your products.
- Protection. Smaller only where it still protects the product.
- Your call. We show the trade-offs; you choose.
