A wholesale purchase order is the document that actually locks in your bulk order — quantities, pricing, delivery date, and terms — before any money changes hands. Skipping details here, or accepting a supplier’s own vague version, is how buyers end up with the wrong quantity, a surprise shipping charge, or no paper trail when something arrives wrong. Here’s what a complete PO should cover and what to check before you sign one.
Purchase Order vs. Invoice: Know the Difference
A purchase order is what you send (or agree to) before the order ships — it’s your request and the agreed terms. An invoice is what the supplier sends after, billing you for what was actually shipped. The two should match on quantity, pricing, and item description; if they don’t, that mismatch is your first red flag. See our guide to reading a wholesale invoice for what the after-the-fact document should look like.
The Core Fields Every PO Needs
A complete wholesale purchase order should include: full buyer and vendor information (legal name, address, phone, and email for both sides); a unique PO number and issue date, plus the expected delivery date; a clear item description with SKU or part number, unit of measure, and quantity for each line; pricing details including unit price, line totals, tax, shipping cost, and grand total, along with payment terms such as net 30; and shipping details covering the ship-to address, delivery method, and any special handling instructions. Authorized signature lines on both sides formalize the agreement and give you a documented record if a dispute comes up later.
Due Diligence Before You Sign
Beyond the paperwork fields, a few checks protect you from a bad bulk order before you commit to it. If the inventory is graded (new, shelf-pull, or defective), get the specific condition breakdown in writing rather than an average “mostly new” claim. Ask for actual timestamped photos of the inventory rather than stock images, confirm the payment structure and timing up front (prepayment, partial deposit, or on delivery), and verify physical specifics like pallet count, dimensions, and weight against your own receiving capability before the order ships. Our distributor verification checklist and MOQ guide cover the broader vetting process this fits into.
Getting the Math Right Before You Order
A purchase order locks in a price, but it’s worth confirming that price actually pencils out before you sign. Factor in the full landed cost — not just the unit price, but freight, prep fees, and any import duties that apply — using our landed cost guide and per-unit cost breakdown. A common mistake is chasing the biggest percentage discount rather than the actual profit margin per unit once all of those costs are included — a smaller discount on a faster-moving item can outperform a deep discount on something that sits.
Keep a Signed Copy Before You Pay
Once both sides agree to the terms, keep a signed or confirmed copy of the PO on file before releasing payment — it’s your reference point if the shipment arrives short, late, or priced differently than agreed. If what shows up doesn’t match what was ordered, the PO and the resulting invoice are the first two documents to compare, and a supplier who won’t reconcile a clear discrepancy is a warning sign worth taking seriously.

FAQ
What should a wholesale purchase order include?
Buyer and vendor information, a unique PO number and date, itemized descriptions with SKU and quantity, pricing and payment terms, shipping and delivery details, and signature lines for both parties.
Is a purchase order the same as an invoice?
No. A purchase order is the request and agreed terms sent before an order ships; an invoice is the bill the supplier sends afterward for what was actually shipped. The two should match, and a mismatch is worth investigating.
What should I check before signing a bulk wholesale purchase order?
Confirm the condition breakdown if inventory is graded, ask for real photos rather than stock images, verify the payment timing, and check pallet count, dimensions, and weight against your receiving capability.
