Quick Answer: What Is a Purchase Order Template?
A construction purchase order template is a fill-in form that orders materials from a supplier at an agreed price. It lists your vendor, the line items with quantity and unit price, the delivery date, and a PO number you can track. Fill it out, print it or save it as a PDF, and your supplier knows exactly what to pull, what it costs, and where to ship it.
Why a PO Beats a Phone Order
For years I ordered materials over the phone and trusted the counter to get it right. Then a lumber invoice came in $300 over what I expected, and I had nothing to argue with. No paper, no agreed price, just my memory against their ticket. A purchase order kills that problem. It is the one sheet that says exactly what I ordered, how much it costs, and when it ships.
This template gives you a clean PO you can fill out at the desk or on your phone, print for the yard, or save as a PDF and email to your supplier. It totals the line items, adds tax and shipping, and gives you a number to track. Materials are usually 40% to 50% of a job, so this is the document that protects the biggest chunk of your cost.
Where the PO fits in your workflow
Four documents, four jobs. The estimate wins the job and sets the price. The purchase order buys the materials from your supplier. The work order dispatches the crew. The invoice bills the customer. Number them and carry the numbers across, and you can trace any dollar from bid to deposit.
What goes wrong without one
- Overbilling you cannot dispute. The invoice comes in high and you have no agreed price to point back to.
- Double orders. Two guys call in the same material because nobody wrote down what was already ordered.
- Wrong delivery. Materials land at your shop instead of the job site, so now you are paying to move them twice.
- Blown job costing. Material spend never gets tied to the job, so you never really know which jobs made money.
Typical material spend by project
Material costs are the line a PO is built to control. Here is roughly what materials run on common residential jobs in 2026. Prices vary by region, so always get a current quote from your local supplier before you lock a PO.
| Project | Typical Material Spend | Common PO Vendors |
|---|---|---|
| Bathroom remodel | $6,000 - $12,000 | Tile, plumbing, vanity supplier |
| Kitchen remodel | $18,000 - $35,000 | Cabinet, countertop, appliance |
| Deck build (300 sq ft) | $4,000 - $9,000 | Lumber yard, hardware |
| Reroof (20 squares) | $3,500 - $7,500 | Roofing supply |
Worked example: a framing material order
Say you are ordering framing lumber for a small addition. Here is how the PO lays it out:
| Description | Qty | Unit Price | Amount |
|---|---|---|---|
| 2x6x10 SPF, kiln dried | 40 each | $9.85 | $394.00 |
| 7/16 OSB sheathing, 4x8 | 24 sheet | $18.50 | $444.00 |
| Simpson hangers + fasteners | 1 lump sum | $165.00 | $165.00 |
| Subtotal | $1,003.00 | ||
| Sales tax (8%) | $80.24 | ||
| Delivery | $75.00 | ||
| Order total | $1,158.24 |
When that lumber lands and the invoice comes in, you match it line for line against the PO. If the OSB jumped to $21 a sheet without a heads-up, you catch it on the spot. Want to confirm your markup before the order goes out? Run it through the markup calculator so the material cost still leaves you the margin you bid.
Tying POs into a paid job
A PO controls what you spend. The other half is making sure you get paid for it. The material cost on your POs should match what you put in front of the homeowner, or your margin walks out the door. Keep the chain tight with a material order checklist so nothing gets ordered twice or forgotten.
EstimationPro carries one job from estimate to proposal to invoice without re-keying anything. You build the estimate with the real material numbers, send the proposal, and the system follows up with the homeowner automatically so you win more of the bids you already send. When the job is done, the invoice goes out and gets paid online. The purchase order is the supply-side piece that keeps your material cost honest from the first bid to the final payment.
Construction Purchase Order Guide
How to write, send, and reconcile purchase orders that protect your material margin on every job.
What Is a Construction Purchase Order?
A purchase order (PO) is a written order you send to a supplier to buy materials at an agreed price before they ship. It locks in the quantity, the unit price, and the delivery date so there are no surprises when the invoice shows up.
- The PO is your order to the vendor with line items and prices
- The vendor invoice is what they bill you against that PO
- The PO number ties the two together so you can catch overcharges
A clean PO is your paper trail. When the lumber yard bills you $1,200 and your PO says $1,050, you have the proof to fix it.
Key Takeaways
- A written order to a supplier at an agreed price
- Locks quantity, unit price, and delivery date
- PO number ties your order to the vendor invoice
What a Complete Purchase Order Includes
A usable PO has 7 core blocks. Miss one and you end up chasing the order by phone.
- Buyer info (your company name, address, contact)
- Vendor info (supplier name, address, counter rep)
- PO number (sequential, so you can track it)
- Required-by date and ship-to (the job site, not the office)
- Line items with description, quantity, unit, and unit price
- Subtotal, tax, shipping, and total
- Terms and a signature line for authorization
Key Takeaways
- 7 core blocks make the order self-contained
- Ship to the job site, not the office
- Spell out unit price so you can audit the invoice
Why POs Protect Your Margin
On a typical remodel, materials run 40% to 50% of the job cost. That is the number a sloppy ordering process quietly eats into.
- Catch overbilling: compare the vendor invoice line for line against the PO
- Stop double orders: one PO number per delivery, no guessing what was ordered
- Job-cost cleanly: POs tie materials back to the right job for real profit tracking
I have caught a supplier billing me for 30 sheets of plywood when the PO said 24. Without that PO, it is your word against the counter ticket. With it, the credit takes two minutes.
Key Takeaways
- Materials are 40-50% of a typical remodel cost
- POs let you audit every vendor invoice
- One PO per delivery prevents double ordering

Frequently Asked Questions
What is a purchase order in construction?
A purchase order is a written order you send to a supplier to buy materials at an agreed price before they ship. It lists the vendor, the materials with quantity and unit price, the delivery date, and a PO number. The PO is your order, the vendor invoice is what they bill you, and the matching PO number lets you catch any overcharge before you pay.
What should a construction purchase order include?
A complete PO includes your company info, the vendor name and address, a sequential PO number, the required-by date, the ship-to address (the job site, not the office), line items with description, quantity, unit, and unit price, the subtotal, tax, and shipping, the order total, and a signature line for authorization.
What is the difference between a purchase order and an invoice?
A purchase order goes out from you to the supplier before materials ship. An invoice comes back from the supplier billing you for what was delivered. You match them by PO number. To bill your own customer for the job, you use a contractor invoice instead.
How do contractors price materials before issuing a PO?
Most contractors price materials at 40% to 50% of the total job cost, then mark them up. Pull current unit prices from your supplier, build the quantities off your takeoff, and confirm your markup with a markup calculator before the order goes out. Lock the unit price on the PO so the delivered invoice matches what you bid.
Does a purchase order count as a contract?
Once the vendor accepts it, a PO is generally a binding agreement to supply the listed materials at the listed prices. It is not the same as your job contract with the homeowner. Keep them separate: the PO controls what you buy from suppliers, and a construction contract controls what you owe the customer.
How do POs help with job costing?
Every PO ties a material cost back to a specific job. When you reconcile the vendor invoice against the PO, you know your real material spend per job instead of guessing. On a typical bathroom remodel that can be $6,000 to $12,000 in materials, and a 5% billing error you never caught is real money. Match the PO and the credit takes two minutes.
