The Short Version
If you're using JobTread to estimate and invoice but skipping purchase orders, you're tracking job costs backward. POs are how you commit a cost at the moment of the buying decision — before the invoice arrives, before the delivery happens, before it's too late to adjust. Builders who run a full PO workflow on every job catch budget variance 2-3 weeks earlier than those who don't, and they protect 4-6 points of margin in the process.
Sound Familiar?
Here's what I see from builders who aren't using POs in JobTread:
- You find out a job is over budget when the final invoice comes in — not when you ordered the materials
- Your JobTread job cost report doesn't match reality because committed costs aren't showing up
- Subs or suppliers bill you for amounts that don't match what you thought you agreed to, and you have no paper trail
- You approve a material order verbally and then forget what the number was by invoice time
- Your project manager has no way to see what's been ordered vs. what's still pending
What We Found
What Purchase Orders Actually Do in JobTread
A purchase order in JobTread does three things most builders don't realize they need until they're staring at a $15,000 variance on a job that seemed fine two weeks ago.
First, it commits the cost. When you create a PO for $4,200 in framing lumber, that $4,200 shows up in your job cost report immediately — before the delivery, before the invoice. You're no longer waiting for supplier paper to know where you stand.
Second, it creates a three-way match. When the invoice arrives, JobTread can match it against your PO. If the invoice is $4,600, you see the $400 variance immediately. You know whether it's a pricing error, a quantity add, or a legitimate scope change before you pay.
Third, it creates a paper trail that protects you in disputes. I've worked with builders who had no documentation for verbal material orders. A supplier delivers the wrong product or overbills — and without a PO, you're arguing from memory. With a PO, you have a timestamped document that shows exactly what was ordered, at what price, for which cost code.
The Number That Changes Everything
In my work with 312+ builders, the ones running PO workflows catch budget overruns an average of 18 days earlier than those tracking costs only through invoices. On a 90-day project, that's 20% of your job timeline when you can still make adjustments.
JobTread's PO module connects directly to your cost codes and budget lines. A PO for roofing materials hits your roofing cost code automatically. When the invoice arrives, it reconciles against the PO. When you're done, your job cost report reflects actual costs, not just what got billed.
The 3-Step PO Workflow That Prevents Budget Bleed
Most builders who say "I tried POs and it was too much work" never built the workflow. They created POs inconsistently, skipped the invoice-matching step, and abandoned it when it felt like double data entry. Here's the system that actually holds.
Step 1: Create the PO before you commit the order. The rule is simple: nothing gets ordered without a PO in JobTread first. That means your PM, your foreman, your office manager — whoever is placing orders — creates the PO in JobTread before calling the supplier. Fifteen minutes of setup prevents hours of reconciliation.
Set up a PO template for your most common material categories: lumber, concrete, roofing, mechanical rough-in, fixtures. The template pre-fills the cost code, vendor, and standard line items. Creating a PO for a standard concrete pour takes under three minutes.
Step 2: Match every invoice to its PO. When a supplier invoice arrives, the first thing you do is pull the matching PO in JobTread. Approve the PO if the amounts match. Flag it for review if they don't — and don't pay until you've resolved the variance.
- Invoice matches PO exactly: approve and pay
- Invoice is higher than PO: verify if scope changed, create a change order if it did, dispute if it didn't
- Invoice is lower than PO: update the PO to reflect actual cost, note the savings
Step 3: Review committed costs weekly, not monthly. Pull your job cost report in JobTread every Friday. Look at committed costs (POs issued) vs. budget per cost code. If roofing materials are 85% committed at 60% completion, you have a problem — and you have time to address it.
The "No PO, No Payment" Rule
The builders I've seen run this most successfully have a firm policy: no PO number means no invoice gets paid. It takes 30 days to train vendors and your team. After that, it's automatic.
This three-step cycle — create before ordering, match on receipt, review weekly — is the difference between knowing your job cost and guessing it.
POs + Cost Codes: The Accountability System Most Builders Never Build
Purchase orders without well-structured cost codes are just organized chaos. POs with the right cost code structure give you a real-time profitability picture at the line-item level — not just at the job level.
Here's what the combination looks like in practice. You're running a $680,000 custom home. Your budget has 22 cost codes. You create POs against those codes throughout the job. At any point, you can pull a report that shows:
- What's been budgeted per cost code
- What's been committed (POs issued)
- What's been invoiced (actual costs to date)
- The variance at each level
That report tells you something most builders never know until the job is done: exactly where your margin is being compressed in real time. If your framing cost code is 12% over committed budget at 50% completion, you can have a conversation with your framer now, not after the job closes.
The builders I work with who run this system also see a secondary benefit: vendor accountability. When a supplier knows you're tracking every PO and matching invoices, they're more careful about what they bill. Billing errors — which average 3-5% of material invoices in the jobs I've audited — drop dramatically when vendors know you'll catch them.
If your cost code structure needs work before POs will give you clean data, that's a separate project — and one worth doing right. A cost code audit typically takes 4-6 hours and immediately improves the quality of every report you run in JobTread.

In JobTread, navigate to the job, select the Purchases tab, and click New Purchase Order. Add your vendor, line items, cost codes, and amounts. Once saved, the PO appears in your job cost report as a committed cost. You can email the PO directly to the vendor from JobTread and attach documents or notes.
Both. Sub POs and material POs serve the same function: committing a cost before it hits your financials as an invoice. For subs, create the PO when you issue the subcontract agreement. This way your committed costs include all labor and material from day one, and your job cost report reflects true exposure, not just what's been billed.
Your budget is the allowance per cost code based on your estimate. A PO is the commitment you make to a specific vendor for a specific amount against that budget. A budget line can have multiple POs (e.g., framing lumber in two deliveries). The budget tells you what you planned to spend; POs tell you what you've actually committed to spend.
Yes. JobTread supports partial billing against a PO. When a supplier delivers half the materials and invoices for half, you mark the PO as partially billed and enter the amount received. The remaining committed balance stays on the PO until fully fulfilled. This gives you accurate open commitments at any point in the job.
