What Is a Bill of Lading? The Shipping Document That Construction AP Needs to Know
A bill of lading — usually called a BOL or B/L — is a legal document issued by a transportation carrier when they pick up goods for shipment. It serves three distinct functions: it's a receipt that the carrier took possession of the goods, a contract between shipper and carrier defining the terms of transport, and (in some forms) a document of title that can be transferred to move ownership of the goods.
For construction AP, BOLs come up when materials travel on common carriers over long distances — structural steel from a fabricator to a site, specialty equipment from the manufacturer, imported materials moving through a port. Local concrete and aggregate deliveries typically don't use BOLs; they use delivery tickets. The distinction matters because BOLs involve carrier liability and freight charges that delivery tickets don't cover.
A standard BOL captures the commercial terms of the shipment.
Standard BOL fields
- Shipper — the party sending the goods (often the manufacturer or supplier)
- Carrier — the transportation company moving the goods
- Consignee — the party receiving the goods (often the contractor or job site)
- Pickup and delivery locations with addresses
- Description of goods — weight, dimensions, count, commodity classification
- Freight classification code — NMFC number for less-than-truckload shipments
- Special instructions — handling requirements, delivery conditions
- Freight charges — who pays (prepaid by shipper vs. collect from consignee)
- Value for insurance purposes (declared value)
- Signature lines for shipper, carrier pickup, and consignee receipt
The two documents look similar and both accompany shipped materials, but they do different work. Understanding the distinction helps AP know what to expect and file appropriately.
Bill of lading vs. delivery ticket
- Issuer — BOL issued by the carrier; delivery ticket issued by the vendor/supplier
- Scope — BOL covers the transport leg; delivery ticket covers the sale and delivery event
- Legal weight — BOL is a contract between shipper and carrier; delivery ticket is a commercial record between vendor and buyer
- Liability — BOL determines carrier liability during transit; delivery ticket documents the vendor's fulfillment
- Freight — BOL shows freight charges separately; delivery ticket usually bundles them
- Typical distance — BOLs on long-haul shipments; delivery tickets on local deliveries from the vendor's own fleet
Several variations of the BOL exist, each with different legal and practical characteristics. The ones that most commonly come up in construction logistics:
Common bill of lading types
- Straight BOL — goods consigned to a specific named party; non-negotiable; the most common form in domestic construction shipments
- Order BOL — negotiable; can be transferred by endorsement; more common in international trade and finance
- Through BOL — covers the entire shipment even when multiple carriers are involved
- Ocean BOL — used for international shipments by sea, covering the ocean leg
- Uniform BOL — follows the standardized template for domestic US trucking
One of the most important functions of a BOL is defining carrier liability — the extent to which the carrier is responsible for damage or loss in transit. Under US domestic trucking rules (49 CFR), standard carrier liability is a per-pound limit unless a higher value is declared. The shipper can declare higher value for more expensive goods in exchange for higher freight rates.
For construction materials, this matters when expensive specialty items (custom steel, imported equipment, specialty finishes) travel on common carriers. If something goes wrong in transit, the BOL terms determine what the carrier has to pay. Contractors who ship high-value materials without declaring value can find themselves underinsured when damage happens.
On shipments of significant value, check whether the BOL declared value matches the actual value of the goods. If the declared value is the default (often $25 per pound or similar), the carrier's liability in a loss is dramatically less than replacement cost. Raising declared value at shipment is cheaper than hoping nothing goes wrong.

BOLs specify who pays the freight charges — prepaid (by the shipper/vendor) or collect (by the consignee/contractor). The terminology matters for AP:
Freight payment terms
- Prepaid — the vendor has paid the freight; the contractor typically reimburses via the vendor's invoice, which lumps freight into the delivered cost
- Collect — the carrier bills the contractor directly for freight; a separate freight invoice arrives from the carrier
- Prepaid and add — vendor prepays freight, then adds it to their invoice as a pass-through line
- Third-party — freight billed to a different party than shipper or consignee
For AP operations, recognizing which scenario applies prevents double-payment of freight. A contractor who receives both the vendor's invoice (with freight embedded) and the carrier's separate freight invoice and pays both has paid freight twice. Reconciling BOLs against vendor and carrier invoices catches this.
On shipments with BOLs, AP reconciliation becomes a bit more complex than standard three-way matching. The elements:
BOL-related AP reconciliation
- Purchase order — what was ordered from the vendor
- Bill of lading — confirms shipment left the vendor and terms of transport
- Receiving log or delivery confirmation at site — confirms arrival
- Vendor invoice — bills for the goods
- Carrier invoice (if collect) — separate bill for freight
- Reconciliation — all documents agree on what was shipped, received, and billed
Discrepancies between the BOL and other documents often surface real issues:
Problems BOL reconciliation catches
- Weight or piece count differs between shipper's BOL and receiver's acknowledgment — material loss in transit
- BOL description doesn't match the PO — wrong item shipped
- BOL issued weeks before delivery — shipment sat somewhere in transit, with potential damage or exposure
- Multiple BOLs for a single PO — partial shipments that need to reconcile to the same invoice
- Freight charges on invoice exceed BOL-stated charges — vendor adding markup that wasn't disclosed
Bills of lading are the transportation-side counterpart to delivery tickets and vendor invoices. For construction AP, they matter most on long-haul or high-value shipments where carrier liability, freight terms, and transit damage all have financial implications. Understanding what a BOL is, how it differs from a delivery ticket, and how to reconcile it against vendor and carrier invoices is part of the basic AP literacy for any contractor with shipped materials arriving on site.
