How to Sign a Packing Slip or Bill of Lading Online

Shipping documents — packing slips, bills of lading, and proof-of-delivery receipts — are the backbone of physical-goods commerce. Without a properly signed packing slip or BOL, accounts payable will not log the shipment, the freight company cannot prove delivery, and any dispute over missing or damaged goods has no documentation to lean on. This guide covers the main shipping documents, how they get signed, the practical differences between facsimile and audit-trailed e-signatures, and how to sign a packing slip or BOL online in a couple of minutes.

Common shipping documents and how they differ

US shipping uses several document types — each with its own purpose and signing convention.

Packing slip — itemized list of goods in a shipment. Includes seller, buyer, line items, quantities, and item identifiers. Used by the receiver to verify that what arrived matches what was ordered. Typically signed only by the buyer’s receiving party as proof of receipt.

Bill of lading (BOL) — the legal contract between shipper and carrier. The standard versions are the Uniform Straight Bill of Lading and the Uniform Order Bill of Lading. Required by federal law for interstate trucking under the FMCSA. Signed by all three parties: shipper, carrier (driver), and consignee on delivery.

Proof of delivery (POD) — confirmation that goods reached the consignee. Often a photo or scan of the signed BOL, or a separate POD form. Used to release payment under freight terms and to support insurance claims for damage.

Commercial invoice — accompanies international shipments and is required by US Customs. Signed by the exporter, listing HS codes, country of origin, and declared value.

Who signs and where

A bill of lading carries signatures from each party at the relevant stage. From the shipper: an authorized representative who tendered the goods (warehouse manager, shipping clerk). From the carrier: the truck driver acknowledging pickup. From the consignee: a receiving manager or authorized signer at the destination.

• Shipper signature: title, signature, printed name, date
• Carrier signature: driver name, truck/trailer number, time of pickup
• Consignee signature: title, signature, printed name, time of delivery
• Exception notes: damage, shortages, or discrepancies recorded at delivery
• Date and time of pickup and delivery are required fields

Ways to sign a shipping document

Paper original — still standard for the majority of US trucking. The driver carries two copies, the receiver signs both, one stays with the carrier and one with the buyer. Adds 3–5 business days to closing the paperwork loop.

PDF with facsimile signature and stamp — fast for low-touch shipments and small-package logistics. The shipper signs and emails the BOL; the consignee signs the received PDF and emails it back. Works well for FedEx and UPS shipments where the carrier has its own electronic POD. More on legal weight in Electronic signatures explained.

Electronic BOL (eBOL) with audit trail — increasingly the standard for LTL and full truckload freight. Platforms like Project44, FourKites, and the standard EDI 211 format let all three parties sign electronically with timestamped audit trails. Required by some major shippers and big-box retailers.

How to sign a shipping document online in 5 minutes

Step 1. Upload the document. If you have a PDF from your TMS or a scanned paper BOL, drag it into the browser. If the document does not exist yet, use the BOL/packing slip builder and fill in the parties.

Step 2. Place the first signature — the shipper’s authorized signer. Drop a facsimile signature in the "Shipper signature" block. Add the printed name if it is not already on the document.

Step 3. Add a second signature for the receiving party (on POD) or warehouse staff (on packing slip). Multiple facsimile signatures can be saved in your account for different employees.

Step 4. Place the company stamp to the right of the signatures. The conventional location is next to the signature block. The stamp slightly overlaps the signature. If you do not have a digital stamp yet, build one right now in the stamp builder without leaving the workflow. The builder supports every common shape: a round corporate seal with company name and EIN, a triangular "FOR DOCUMENTS" stamp, a rectangular shipping-department stamp. Once built, the stamp is saved and drops onto the next BOL with one click.

Step 5. Save as PDF and send. Email it to the counterparty for their signature, or send it through your TMS. A shipping document closes in 30 minutes instead of 5 days.

Federal requirements for electronic shipping documents

Under the FMCSA’s eBOL pilot program (now standard in many fleets), an electronic bill of lading carries the same legal weight as a paper one. The 2022 SHIP IT Act formalized the use of electronic BOLs across interstate freight, provided that all three parties accept electronic execution.

For domestic packing slips and proof-of-delivery receipts the requirements are looser: a facsimile signature with a stamp is fine when both parties agree to electronic execution under ESIGN/UETA. The IRS and most state tax authorities accept electronically signed shipping documents during audits.

Common mistakes when signing shipping documents

First — number mismatches between figures and words. If the line items total $125,000 in numbers but "one hundred fifty thousand" in words, the document can be challenged. Auto-fill the words in the builder to avoid this.

Second — stamping over line items. The stamp belongs in the bottom signature block, not on top of quantities or unit prices. Otherwise it becomes unclear what was actually shipped if the document is later disputed.

Third — no power of attorney for the signing party. If a warehouse clerk signs instead of a manager, there should be a delegation policy on file. Without it, the signature can be challenged.

Fourth — incorrect consignee details. The receiving party’s legal name and address must match the contract or PO exactly. One typo, and AP cannot match the BOL to the order, delaying payment.

Related documents: invoices and statements of work

A shipping document usually pairs with an invoice and, for services, a statement of work or completion certificate. The whole package can be signed in one tool: invoice in the builder, packing slip from the invoice, completion certificate from the SOW. Stamps and signatures pull from saved templates automatically.

If your company does not have a digital stamp yet, build one in the stamp builder once: any common type — round corporate seal, triangular "FOR DOCUMENTS," rectangular shipping-department stamp — comes together in two minutes without a designer. Once saved, it is available across the editor for invoices, BOLs, and completion certificates.
