Related resources and link policy
ShipMargin focuses on shipping, customs and ecommerce calculations. Preparing a shipment can also involve documents and listing images, so this page links to a separate resource for those tasks.
Where a reader needs something outside that scope, we point at people who cover it properly.
ToolsBay
Tools for preparing documents and listing images. Check the selected tool’s processing and privacy details before providing shipment documents or customer information.
If you need to fold a commercial invoice, packing list and certificate of origin into one PDF, get a file under a broker portal's upload limit, or convert listing photos into a format a marketplace will accept, that is the place to go. We would rather send you somewhere useful than build a worse version of a tool that already exists.

Links to carriers, marketplaces and government tariff lookups let you inspect the source and check whether a rule applies to your shipment or account. A citation supports the specific rule discussed, not every statement elsewhere on the linked site.
Adarsh Bora owns both ShipMargin and ToolsBay. Links to ToolsBay are to our sister project, not an independent recommendation. It is linked here for document and image tasks outside ShipMargin's calculators, not as a source for our carrier rates, marketplace fees or customs rules. Those references are listed separately in the source register.
On affiliate relationships
We do not currently run affiliate links inside any calculator, and if that changes there are two rules we will hold to. The honest answer comes first, before any commercial suggestion. And anything we earn from will be labelled on the page, not buried in a footer.
Our calculators provide planning estimates. They do not sell postage or book transport, and entering a price does not create an offer from a carrier or marketplace.
Working with us
We are open to a few specific things: correcting a rate we have wrong, a data partnership where you publish authoritative fee or tariff data, or embedding our calculators on your own site. The embed page covers the last one. For the others, use the contact page.
We are not open to paid guest posts, link exchanges, or "we noticed a broken link on your page" emails that are about neither.
