What paperwork travels with a B2B shipment?

Every B2B shipment travels with a small stack of documents — some physical, some electronic, all doing a specific job. The bill of lading is the one that matters most, the packing slip is the one receivers use first, and the rest depends on where the freight is going and what it is. Here’s each document, what it does, and who it serves.

The bill of lading — the shipment’s contract

The bill of lading (BOL) is the master document of commercial freight. It identifies the shipper and receiver, describes the freight — piece count, weight, dimensions, description — and records the terms under which the carrier is moving it. It’s signed by the shipper at pickup and by the receiver at delivery, which makes it three documents in one: a receipt for what the carrier took custody of, a contract of carriage, and the backbone of the delivery record.

When something goes wrong — a shortage, damage, a dispute about what was tendered — the BOL is the document everyone reaches for. That’s why its accuracy is worth thirty seconds of care at pickup: the piece count on the paper should match the freight on the truck before anyone signs. For a field-by-field walkthrough, see our bill of lading guide for Ontario shippers, or start with the plain-language answer to what a bill of lading is.

You’ll also hear “waybill” used around courier shipments — a related but simpler document. The differences are covered in waybill vs. bill of lading.

The packing slip — the receiver’s checklist

The packing slip lists what’s inside the shipment: items, quantities, part numbers, and usually the purchase order they fulfil. It exists for the receiver, whose first job at the dock is answering one question — did we get what we ordered? The packing slip is how they answer it without opening every carton on the spot.

Two conventions make packing slips useful in practice:

• Attach it to the freight, typically in a plastic pouch on the outside of a carton or skid, so it arrives with the goods rather than in someone’s inbox.
• On multi-skid shipments, put it on one skid and mark which — or duplicate it — so receiving staff aren’t hunting through stretch wrap for the paperwork.

Note what the packing slip is not: it’s not the carrier’s document. The driver moves freight against the BOL’s piece count; what’s inside the cartons is between shipper and receiver. Keeping those two documents consistent — the BOL’s counts matching the packing slip’s shipment — is one of the quiet disciplines of clean shipping, and it’s covered in our overview of B2B shipping documentation basics.

Delivery and handling instructions

Plenty of shipments carry a third layer: instructions. Deliver to door 7. Call the site super before arriving. Do not double-stack. This side up. Receiver closes at 4:30. Some of this rides on labels, some goes into the booking so the dispatcher and driver see it, and some travels as a note with the paperwork.

The best practice is to put instructions where they’ll be seen at the moment they matter: routing and timing details in the booking, handling markings on the freight itself. Companies that ship inbound freight from many suppliers often standardize this — our guide to writing supplier shipping instructions shows how those documents keep dozens of shippers consistent.

Paperwork that joins for specific freight

Beyond the core stack, certain shipments add documents of their own:

• Commercial invoice and customs paperwork — for cross-border freight, the commercial invoice declares what the goods are and what they’re worth so customs can clear them. Brokers and customs processes sit alongside the transportation itself. (Sonic Transport arranges cross-border moves through transportation partners, with the same single point of contact.)
• Dangerous goods documentation — regulated dangerous goods travel with declarations under TDG rules, and the legal duty to identify, classify and declare them sits with the shipper. Certified DG handling is a confirmation each carrier must make about its own operation; never assume it, and never ship undeclared DG.
• Certificates and compliance records — some industries attach material certifications, chain-of-custody records, or quality documents the receiver requires with the physical goods.
• Return paperwork — return authorizations (RMAs) on reverse shipments, so the original vendor’s receiving dock knows what’s coming back and why.

If your freight falls in one of these categories, say so at booking. Documents like these aren’t decoration — they’re often the difference between freight that’s accepted and freight that’s refused at the door.

The document that comes back: proof of delivery

One document in the cycle travels in reverse. When the receiver signs at delivery, that signature — captured on the BOL or the carrier’s delivery record — becomes the proof of delivery, the closing bracket on the shipment. It confirms who received the freight, when, and in what condition, and it’s what your invoicing and any claims lean on afterwards. How that record makes its way back to you is its own small process, covered in how you get your proof of delivery.
