What Belongs on a Lamp Purchase Order: The Fields That Prevent Disputes

When a shipment goes wrong, the purchase order is the only document both parties can point at. If it says floor lamps, black, two hundred units, there is room for two perfectly reasonable interpretations that differ on shade material, cord length and bulb inclusion. Neither party is being difficult. The order was simply never specific enough to be wrong.

Model and finish, as two separate fields

This is the single change that prevents the most problems. The model identifies the construction and the finish identifies the colour, and a purchase order should carry both independently. When they are merged into one description, a reorder has to be matched by eye against the original, and eyes disagree.

Where a supplier operates finish codes, use theirs verbatim. A code that can be quoted back is worth more than a description that sounds right.

Quantity, packaging unit and tolerance

Separating installed quantity from attrition quantity is worth doing even when both ship together. It makes the next reorder trivial, because the replacement rate is already recorded in the same units the property counts in.

• State whether the quantity is units or cartons, and give the other figure as a cross-check.
• State the carton quantity per model, because it drives both freight and receiving.
• State the tolerance you will accept on a production run, and what happens outside it.
• State the attrition or spare quantity separately from the installed quantity, so both stay visible.

The commercial fields

Record the unit price in the currency it will be paid in, the total, the payment structure including any deposit, and the delivery term. The delivery term matters more than it appears to, because it determines who carries the risk and the freight cost at each stage of the journey; Incoterms for Lighting Orders, in Plain Language is the reference for that.

Record the quote reference and its validity date. A quote that has expired is not a price, and a purchase order that cites an expired quote invites a conversation nobody wants to have.

Record the requested dispatch date and the delivery window separately. They are different commitments with different owners, and conflating them is the source of most timing arguments. How Long Is a Lamp Quote Good For? covers the mechanics of validity, and Payment Terms in Lighting Sourcing covers the money side.

The specification fields

Include the socket type, the maximum wattage marking required, the plug type, the cord length and the control type, even when the supplier already knows the model. These are the fields an inspector will check against the product, and they are the fields most often assumed rather than stated.

Include any marking and packaging requirements, including country of origin where it applies. The reference for that is What Has to Be Printed on a Lamp Carton.

Finally, name the person who signs off on samples and the person who receives goods. Most disputes are resolved or created by whoever happens to be in the room when the cartons are opened.

The fields that decide who pays when something goes wrong

Two clauses carry more weight than the rest: the delivery term and the damage provision. The delivery term decides where risk transfers. The damage provision decides what evidence is needed and how quickly it has to be produced.

Most arguments are not about whether goods were damaged but about when the damage has to be reported and what counts as proof. A purchase order that states the window and the evidence removes the argument before it starts.

The inspection step is where this is caught, which is why What to Inspect When a Lamp Shipment Lands at Your Dock matters more than most buyers expect. Inspecting cartons before unpacking them, and units before distributing them, is what turns a claim from theoretical into possible.

Freight is the related trap. If the delivery term is not stated, the freight quote is not comparable, and the unit prices were never actually competing. Incoterms for Lighting Orders, in Plain Language sets the options out in ordinary language.

• Delivery term, stated by its standard abbreviation and place.
• Damage reporting window, in days from receipt.
• Evidence required, named specifically rather than implied.
• Currency of payment, and who carries the transfer cost.

Frequently asked questions

Is a model description enough, or do we need codes?

Codes. A description can be read two ways; a code can be quoted back and checked. If a supplier does not use codes, agree one with them and write it into the specification.

Should the purchase order repeat specification data the supplier already holds?

Yes, for the fields that get inspected: socket, maximum wattage, plug, cord length and control. Repeating them costs a line of typing and prevents a whole class of dispute.

What is the most commonly missing field?

Carton dimensions and gross weight. Without them the freight cannot be quoted accurately, and the unit price comparison is not yet meaningful.
