Materials Procurement vs. Invoice Financial Verification
Kojo helps you source, RFQ, and order materials end-to-end. CheckIT verifies that what arrives — and what you're billed for — actually matches what you contracted. Different stages of the same procurement cycle.
Pre-PO sourcing is one job. Post-invoice verification is a different one.
Quick verdict
What Kojo does
Kojo is the most heavily capitalized pure-play construction procurement platform in the market — ~$94M raised, 600+ contractor customers, and an October 2025 strategic investment from Wesco International that embeds real-time supplier pricing and availability directly inside the Sourcing Grid. Kojo runs from field request to PO to delivery.
- 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
- Warehouse Inventory + Tool Tracking — real-time stock and asset visibility across yards and projects
- Kojo Prefab + Kojo Intelligence — shop-floor workflow plus AI for RFQ automation and document data transfer
Kojo is widely regarded as best-in-class on trade-contractor field-to-purchasing workflow. The Wesco supply-chain integration is a genuine advantage we respect.
What CheckIT Invoice does
CheckIT compares every line on an incoming invoice against the executed contract baseline — material, quantity, unit rate, and total — and returns an explainable dollar-delta result the CFO or Controller can defend. Document-in, report-out. No ERP integration. No 60-day rollout. Minutes per invoice, not the better part of an hour.
- Line-Item Verification — every line of every invoice checked against contract, quote, or rate sheet
- Three Verification Modes — Mode A (Quote → Invoice), Mode B (Rate Sheet), Mode C (Rolling 12-Month Historical)
- Explainable Deterministic + AI Engine — line-item math you can defend in a dispute, not a black-box confidence score
- Audit-Ready Output — annotated PDF with which line, why it's wrong, exact dollar impact, severity rank
- No ERP Required — upload a PDF, get a verified result. No IT, no procurement-team buy-in, ROI on document one
Built for the PM, Controller, and CFO who need a defensible number — not for the procurement manager running the sourcing workflow.
Feature comparison
Different stages of the same procurement cycle.
Kojo and CheckIT live one stage apart in the same project. Kojo runs from takeoff to PO to delivery — its job is to make sure the contractor sources the right materials, from the right vendor, at the best available price, and that field, office, warehouse, and accounting all see the same data. The October 2025 Wesco partnership makes that easier: real-time pricing and availability from a national distributor embedded inside the Sourcing Grid. That's a genuine supply-chain advantage. We respect it.
But the moment a delivery becomes an invoice, the question changes. The question is no longer “did we pay the quoted price?” It becomes “does this invoice line match what we actually contracted for — the executed rate, the executed unit, the executed quantity, the executed scope?” That question is where the leak lives — errors that slip through AP. Procurement tools don't answer it — they weren't built to. AP-routing tools don't answer it either. The PM is too deep in the field. The Controller is too deep in the close. The CFO finds out three months later in the WIP review.
39% of construction invoices contain at least one error. 2.5% average overbilling on invoice value.
Industry benchmark data, CheckIT briefing pack, May 2026
CheckIT answers it. Every line. Minutes per document — a 75% reduction in review time. Explainable dollar-delta. It does not replace Kojo. It catches what Kojo wasn't built to catch — the post-delivery, post-PO billing errors that show up only when someone actually compares the bill to the deal.
If you need pre-PO sourcing speed, Kojo is the right call.
A self-perform electrical contractor with 80 field crews texting material requests, three different distributor reps to call for pricing, and a procurement manager rebuilding the same spreadsheet every Monday. Kojo's mobile app, Sourcing Grid, and Wesco integration compress that whole loop. That's the job they were built for, and they do it well.
If you need post-invoice verification, CheckIT is the right call.
A mid-market GC running 25 subcontractor T&M billings a week against executed rate sheets — or an industrial owner whose PMC just forwarded a $480K change-order invoice with 70 line items. The PM hasn't time to walk it. CheckIT does, in minutes, with a dollar-delta the Controller can defend.
The cost of not verifying
Every unverified invoice is a bill paid on trust. These are the numbers behind why we built CheckIT — and why Kojo's procurement variance, useful as it is, isn't the same answer.
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
Not as its core build. Kojo's variance reporting answers “did we pay what we were quoted?” — a procurement variance, not a contract-baseline verification. It does not parse a subcontractor T&M invoice line-by-line against the executed rate sheet and return a defensible dollar-delta. CheckIT was built specifically for that downstream job.
Yes — and we'd argue you should. Kojo prevents overpaying upfront by sourcing the best quoted price; CheckIT catches the overbilling that slips through after delivery, when the invoice doesn't match what was actually contracted. Different stages, complementary in a well-defended construction stack. Most CheckIT customers already use a procurement workflow tool.
Different pricing models, hard to compare apples-to-apples. CheckIT is per-document or per-engagement with public pricing and value on document one. Kojo is a custom enterprise platform fee scaled by company size — not publicly disclosed and typically a six-figure annual commitment with a multi-month implementation.
Minutes. Upload one invoice and one contract; get a verified result in minutes. No ERP integration, no IT, no procurement-team rollout. That's the structural difference from a workflow-replacement tool.
Field-to-purchasing workflow, real-time distributor pricing, and warehouse/tool/prefab visibility for trade contractors. If your bottleneck is sourcing or your field crews are still texting material lists, Kojo is the right tool. CheckIT doesn't compete there.
