Both check invoices. The difference is what they check against.
Kojo runs materials buying end-to-end, and its Automated Invoice Matching checks an invoice against the purchase order and the delivery receipt — which works, in Kojo's own words, because the PO was already created in Kojo and the delivery was already logged in the field or warehouse. CheckIT checks the invoice against the quote the job was bid on — or a rate sheet, or your own price history — using only the documents you already have.
No PO required. No purchasing workflow to adopt. Nothing for the field to log first.
Quick verdict
What Kojo does
Kojo deserves a straight description: it's the most heavily capitalized pure-play construction procurement system in the market — ~$94M raised, 600+ contractor customers, and an October 2025 strategic investment from Wesco International that puts real-time supplier pricing and availability inside the Sourcing Grid. Kojo runs the materials loop from field request to PO to delivery — and, with Automated Invoice Matching, on to the invoice.
- Field Material Requests — mobile shopping-cart UX for crews; reviewers cite ~50% time savings
- Sourcing Grid + RFQ — side-by-side live and historical vendor pricing including Wesco, Graybar, Border States
- Purchase Orders + ERP sync — Standard/Rental/Service/Subcontract POs; Procore, Sage 300 CRE, Sage Intacct
- Automated Invoice Matching — OCR reads the invoice PDF instead of someone keying it in, the lines are matched against the purchase order and the delivery receipt, and price, quantity, or delivery discrepancies are highlighted automatically; corrections go back to the vendor and corrected invoices sync to accounting
- Warehouse Inventory + Tool Tracking — real-time stock and asset visibility across yards and projects
- Kojo Prefab + Kojo Intelligence — shop-floor workflow plus automation for RFQ handling and document data transfer
Kojo is admirably direct about why the matching works: it's only possible, in their words, because Kojo is an all-in-one procurement and inventory management system — before the invoice is issued, the PO was already created in Kojo and the delivery was already logged in the field or warehouse. That starting point is what this page is about.
- Invoices with no purchase order behind them — field orders, counter tickets, will-call runs — since the matching starts from the PO Kojo issued
- The price you actually bid: matching is to the PO and the delivery receipt, not to the quote the job was estimated from, a rate sheet, or your own price history
- Subcontractor T&M billings, and any invoice that never entered the purchasing workflow at all
What CheckIT Invoice does
CheckIT Invoice checks every line of an incoming invoice against the quote the job was bid on — or a rate sheet, or your own price history — material, quantity, unit rate, and total, and puts a dollar figure on every difference the Controller can defend. Documents in, findings out. Nothing for the field to log first. Minutes per invoice, not the better part of an hour.
- Line-Item Checking — every line of every invoice against the quote, a rate sheet, or your own price history
- Three Verification Modes — Mode A (Quote → Invoice), Mode B (Rate Sheet), Mode C (Rolling 12-Month Historical)
- Explainable Engine — line-item math you can defend in a dispute, not a black-box confidence score
- Audit-Ready Output — annotated PDF showing which line, why it's wrong, and the exact dollar impact, ranked by how much it matters
- No PO, No Workflow, No ERP Required — send the documents you already have and get a checked result
It runs on any vendor's invoice, bought any way — including the counter sale nobody wrote a PO for. And the books stay yours: the QuickBooks Online connection is live, so approved invoices push into QuickBooks Online as cost-coded bills. An accelerator, never a prerequisite.
Feature comparison
Kojo's matching starts from its own PO. CheckIT starts from the quote you bid.
Kojo ships Automated Invoice Matching, and it's a real feature. OCR reads the invoice PDF so nobody keys it in, the lines are matched against the purchase order and the delivery receipt, price, quantity, and delivery discrepancies get highlighted automatically, and corrections go back to the vendor and on to accounting. If your buying already runs through Kojo end to end, that is a good answer to the billing question.
Kojo is admirably direct about why it works. Matching this easy, in their words, is only possible because Kojo is an all-in-one procurement and inventory management system: before the invoice is issued, the PO was already created in Kojo and the delivery was already logged in the field or warehouse. Two documents have to exist first, and both have to come from inside the system.
That's the whole difference. CheckIT starts from the quote the job was bid on — or a rate sheet, or your own price history — and needs nothing but the documents you already have. No PO, because the field order and the counter ticket never had one. No purchasing workflow for the office to adopt, and nothing for the crew to log before an invoice can be checked. So CheckIT reads any vendor's invoice, bought any way, and answers a different question: not “does this match what we ordered?” but “does this match the price we bid the job on?” A PO can be issued above your bid number and still match perfectly.
Neither approach makes the other pointless. Kojo's matching is strongest exactly where its own purchasing flow was used end to end. CheckIT is strongest on everything else — every line, minutes per document, a 75% reduction in review time, and a dollar figure you can put in front of the vendor.
If your buying already runs through Kojo end to end, its own matching is the shortest path.
A self-perform electrical contractor with 80 crews requesting material in the app, POs going out of the Sourcing Grid, and deliveries logged at the yard has both documents Kojo's matching needs, already sitting in the system. That's the case it was built for, and it's a good one. The invoices worth counting are the ones outside it: the counter tickets, the field orders nobody wrote a PO for, the job where deliveries stopped getting logged in week three, and the sub's T&M billing that was never a materials purchase at all.
If the invoices you worry about never came from a PO, CheckIT is the right call.
Two buy waves, a dozen supply-house accounts, will-call runs on every truck, and a quote you bid the job from three months before the price moved. CheckIT checks each invoice against that quote — or a rate sheet, or your own price history — and hands back every difference in dollars, ranked, in minutes. Nothing for the field to log first, and no purchasing workflow to stand up before the first answer.
Or run both — Kojo for buying, CheckIT for the billing check.
Keep requisitions, POs, and deliveries in Kojo and send CheckIT the same invoices along with the quote you bid from. No connection between the two systems is needed. An invoice can match its PO and its delivery receipt exactly and still be priced above the number you won the job with — that's a different question, and it's the one that protects margin. If you adopted Kojo mainly for the invoice matching, run one job through the free audit and compare what each catches before your next renewal.
What this looks like in your trade
Kojo is built for trade contractors' purchasing, and its matching works from the PO it issued. Here's what that leaves open in each trade.
Electrical
Kojo's roots are in electrical purchasing — requisitions and POs for wire, conduit, and gear. What a PO match doesn't settle is whether the invoice price matches the quote you bid when copper was cheaper. CheckIT puts a dollar figure on that, line by line.
CheckIT for Electrical ContractorsHVAC
Equipment ordered months out arrives after price-increase letters and freight surcharges. The PO got issued and the delivery got logged; the price still moved. CheckIT checks the invoice against the number you actually bid.
CheckIT for HVAC ContractorsPlumbing
Requisitions cover the planned buys. The counter tickets and will-call runs across a dozen supply-house accounts never had a PO to match against — and CheckIT checks those against the quote too.
CheckIT for Plumbing Contractors
The cost of not verifying
Every unchecked invoice is a bill paid on trust. These are the numbers behind why we built CheckIT — and the invoices that never ran through a purchasing system are the ones worth counting.
Across the trades, 39% of construction invoices contain an error.
As a share of invoice value — quietly compounding across every job.
Minutes per document instead of the better part of an hour.

CheckIT vs. Kojo — common questions
Because the two start from different documents. Kojo matches an invoice against the purchase order it issued and the delivery receipt logged in Kojo; by its own description, that's what makes the matching work. CheckIT checks the invoice against the quote the job was bid on, a rate sheet, or your own price history, using only the documents you already have. So CheckIT reaches the invoices with no PO behind them — counter tickets, field orders, a sub's T&M billing — and it catches a price that sits above what you bid even when the invoice matches its PO exactly.
That's the common case CheckIT was built for, and it changes nothing about how it works. Send the invoice and the quote you bid from — or a rate sheet, or neither, and CheckIT checks against your own price history — and you get every difference in dollars, ranked by how much it matters. Matching against a purchase order needs a purchase order. Checking against a quote doesn't.
Yes, and no connection between the two systems is needed. Keep buying through Kojo and send CheckIT the same invoices with the quote you bid from. Kojo's matching answers “does this invoice match the PO we issued and the delivery we logged?” CheckIT answers “does this invoice match the price we bid the job on?” — including on the invoices that never had a PO. Plenty of shops run CheckIT alongside a purchasing system.
Different models, so there's no apples-to-apples number. CheckIT's pricing is published: plans from $455 per month per business location with unlimited seats, annual prepay gets a month free, and the first assessment is free. Kojo's pricing is quoted through its sales team and isn't published, so we won't guess at it. The comparison that matters is what each costs to get running, and what a free audit finds on one of your own jobs.
Minutes. Send one invoice and the quote you bid from and you'll have a checked result in the same sitting. No PO to issue, no ERP integration, no IT project, and nothing for the field or the office to adopt first. That's the structural difference from getting the billing answer out of a purchasing system.
Buying. Field-to-purchasing workflow, live distributor pricing in the Sourcing Grid, warehouse and tool tracking, and prefab — CheckIT does none of that and isn't trying to. If your bottleneck is how material gets ordered rather than how it gets billed, Kojo is the right tool for that job.
