Drop Ship Purchase Order: How Dropship POs Work

A drop ship purchase order is a purchase order a retailer sends to a supplier that instructs the supplier to ship the goods directly to the retailer's end customer instead of to the retailer. The retailer never touches the inventory. The customer's shipping address sits on the PO, and the supplier fulfills and ships under the retailer's branding, so the buyer looks like the one who shipped it.

Drop shipping runs on purchase orders. Every time a customer buys, the retailer turns that order into a PO to a supplier, and the accuracy of that PO decides whether the right item reaches the right doorstep. This guide explains how a drop ship PO works, how it differs from a standard PO, what blind dropshipping means, and where the process breaks when the volume climbs.

How a drop ship purchase order works

The flow has three parties instead of two: the customer, the retailer (or seller), and the supplier (or manufacturer). The retailer holds no stock. When an order comes in, the retailer issues a PO to the supplier that carries the customer's ship-to address, and the supplier ships straight to that customer.

1. A customer places an order on the retailer's store and pays the retail price.
2. The retailer issues a drop ship purchase order to the supplier at the wholesale price, with the customer's name and address as the ship-to.
3. The supplier picks, packs, and ships the item directly to the customer, often with the retailer's branding on the label and packing slip.
4. The supplier invoices the retailer for the wholesale cost; the retailer keeps the margin.

Because the ship-to on the PO is a consumer, not the retailer's warehouse, drop ship POs tend to be single-line or few-line orders sent in high volume, one per customer order. That is the opposite of a bulk restock PO, and it is why drop ship sellers process far more purchase orders than a traditional retailer of the same size.

Drop ship PO vs standard purchase order

A standard purchase order ships to the buyer's own location for stock or use. A drop ship purchase order ships to a third party, the buyer's customer, and usually hides the supplier's identity. The table sums up the differences.

What is blind dropshipping?

Blind dropshipping is a drop ship arrangement where the supplier ships the order without any of their own branding, invoices, or identifying paperwork, so the customer believes the retailer shipped it. The supplier strips their name from the packing slip and the shipping label and uses the retailer's return address instead. This is written into the purchase order terms up front and confirmed before the supplier ships.

There are two levels. In single blind shipping the customer never learns who the supplier is, which is the standard setup for most dropshippers. In double blind shipping neither the customer nor the supplier knows the other party, usually because a third-party logistics provider sits in the middle and replaces both names on the paperwork. Retailers use blind shipping to protect margins and stop customers or competitors from going straight to the source.

Blind PO has a second meaning: blind receiving

Watch the wording. Outside dropshipping, a "blind purchase order" can also mean a blind receiving document, where the quantities are deliberately left off the copy given to the warehouse. Receiving staff have to count the goods and record what actually arrived rather than confirming a number in front of them, which forces an honest count and catches short shipments. If you see "blind PO" in an accounts payable or inventory context, this is usually what it means, not dropshipping.

Why drop ship purchase orders break at volume

The drop ship model lives and dies on clean PO data. Because there is one PO per sale and the ship-to is a different customer every time, errors compound fast: a wrong address ships to the wrong person, a wrong SKU sends the wrong product, and a missed line delays an order the customer already paid for. Many suppliers still send order confirmations, updated POs, and back-order notices as PDFs or emails rather than clean data feeds.

That is where the data-entry load piles up. Every supplier document that arrives as a PDF has to be read and reconciled against what the retailer sent. You can hand those documents to the converter above to pull the header and line items into Excel, CSV, or JSON automatically, and when the volume of small supplier charges hits your bank feed, it helps to turn the statement into a spreadsheet you can reconcile line by line. For the purchase orders themselves, structured extraction means the ship-to, SKU, and quantity land in your system exactly as written.

Frequently asked questions

What is a drop ship purchase order?

It is a purchase order a retailer sends to a supplier telling the supplier to ship the goods directly to the retailer's end customer. The customer's address is the ship-to on the PO, and the retailer never physically handles the product. The supplier fulfills the order and bills the retailer at wholesale.

What is the difference between drop shipping and blind shipping?

Drop shipping is the fulfillment model where the supplier ships straight to the customer for the retailer. Blind shipping is a condition on that shipment: the supplier removes their own branding and paperwork so the customer only sees the retailer's name. You can drop ship without it being blind, but most dropshippers require blind shipping to protect the relationship.

Who is the ship-to on a drop ship PO?

The end customer who bought from the retailer. This is the key difference from a standard purchase order, where the ship-to is the buyer's own warehouse. On a drop ship PO the bill-to is the retailer and the ship-to is a consumer address, which is why each PO is unique.

Does the customer see the supplier's name?

Not if the arrangement is blind. Under blind dropshipping the supplier ships with the retailer's branding on the label and packing slip and leaves out their own invoice, so the customer believes the order came from the retailer. This has to be agreed in the purchase order terms and checked before shipment.

Why do dropshippers process so many purchase orders?

Because there is typically one purchase order per customer sale rather than periodic bulk restocks. A dropshipper that gets a thousand orders sends close to a thousand POs, each with a different ship-to. That volume is why automated PO data capture matters more in dropshipping than in traditional retail.
