AP Routing vs. Invoice Verification
AvidXchange routes invoices for approval and pays your vendors. CheckIT verifies that every line on those invoices matches the rate and quantity you contracted for. Different layer, different job.
Faster approvals don't catch overbilling. Verification does.
Quick verdict
What AvidXchange (TimberScan) does
AvidXchange has automated accounts payable since 2000. Their construction product, AvidSuite for Construction, is built around TimberScan (Sage 300 CRE-native) and TimberScan Titanium (Sage 100 Contractor, Sage Intacct, Acumatica, Workamajig). The pitch is honest: “Automate your AP without replacing your ERP.” It's an overlay on the systems you already run.
- Invoice capture, OCR, and header-level coding into your ERP
- Approval workflow routing — by vendor, job, role, or dollar threshold
- Lien-waiver management tracked against jobs and commitments
- Vendor payment execution through AvidPay's 1.3M+ supplier network
Construction is one vertical of many for AvidXchange — not the primary build.
- Whether the rate, quantity, or unit on any individual line matches the contract behind it — TimberScan matches invoice totals to PO totals, not line to contract
- Whether billed quantities reconcile to the delivery ticket
- Rate-sheet or rolling 12-month historical price baselines
- Dollar-quantified, severity-ranked discrepancies per line
What CheckIT Invoice does
CheckIT Invoice compares every line on an incoming invoice against your contract, quote, rate sheet, or rolling 12-month historical baseline — and returns an explainable report: which line is wrong, why, and the dollar delta. Typically in minutes per document.
- Line-item verification across three modes: Mode A (Quote → Invoice), Mode B (Rate Sheet), Mode C (Rolling 12-Month Historical)
- Explainable dollar delta per line, severity-ranked, defensible to a CFO
- No ERP integration — document in, report out, alongside whatever AP tool you already run
- 75% reduction in manual review time per document
CheckIT doesn't replace TimberScan. CheckIT verifies the numbers TimberScan is routing for approval.
Feature comparison
AvidXchange routes the invoice. CheckIT verifies it's right.
There's a quote in the CheckIT founders' deck that we use unedited because it says it better than we can.
“We have AvidXchange TimberScan and still HAVE TO manually check invoices.”

That's not a slight against AvidXchange. TimberScan does exactly what it claims to do — captures invoices, routes them through approval, matches headers to POs, tracks lien waivers, and pays vendors through AvidPay. AvidX users report ~50% faster AP approval cycles.
But “approved” is not the same as “correct.” TimberScan operates at the header and total level — invoice total against PO total. Line-item verification — checking whether the rate, quantity, unit, and material on every individual line match the contract — is a different job that lives one layer deeper in the stack.
Industry data puts the unverified-content gap in plain sight: 39% of construction invoices contain at least one error, and overbilling averages 2.5% of invoice value. CheckIT cuts the manual line-item check a Controller or PM still does by 75% — minutes instead of the better part of an hour — with an explainable, dollar-quantified report.
If you need AvidXchange: an AP manager on Sage 300 CRE or Acumatica drowning in approvals.
You're fielding vendor calls about payment status and routing paper-and-PDF invoices by hand. TimberScan's routing engine, mobile approvals, lien-waiver tracking, and AvidPay's supplier network are built for exactly that. It still leaves open whether the rate on Line 14 matches your contract — TimberScan matches at the header and total level, not the line.
If you need to know the invoice is right before you approve it.
You're a PM, controller, or CFO at a mid-market GC and your team is still manually line-checking invoices (or worse — they aren't, and the variances are bleeding through to gross margin). CheckIT does line-item verification in minutes with an explainable dollar-delta report. No ERP integration. ROI on document one.
The honest answer for most mid-market GCs: run both.
AvidX routes the invoice. CheckIT verifies it. The AP team gets cycle-time relief. The PM/CFO gets dollar accuracy. Neither tool is doing the other's job.
What this looks like in your trade
Faster AP is the point of automation. The billing check has to happen before the routing — trade by trade.
General Contractors
Routing and payment automation moves an overcharge as fast as a clean invoice. CheckIT checks each invoice against the quote first, so what enters the flow is verified.

Lien waivers and payment files don't test unit prices against quoted rates. CheckIT does, line by line, and totals the drift across the job before it's paid.

The cost of not verifying
Every unverified invoice is a bill paid on trust. These are the numbers behind why CheckIT exists.

CheckIT vs. AvidXchange (TimberScan) — common questions
Yes — that's how most mid-market GCs end up running them. AvidX captures, routes, and pays. CheckIT plugs in alongside as the verification layer: drop the same invoice and your contract or rate sheet into CheckIT, and you get back a line-by-line dollar-delta report before TimberScan routes the invoice for approval. No integration required between the two — they touch the same documents, not the same database.
No — TimberScan matches at the header and total level, not the line. It compares the invoice total to the PO total, validates vendor and GL code, and routes for approval. Whether the rate per cubic yard on Line 14 matches your contract, or whether the billed quantity reconciles to the delivery ticket, isn't part of the workflow. That's the gap CheckIT fills.
AvidXchange went private in October 2025 in a $2.2B deal — TPG Capital took majority control with Corpay holding ~34% and an option to acquire the rest in 2028. Corpay's CEO has said publicly that the deal will be accretive to Corpay earnings in 2026, which signals a payments-first investment thesis. For customers, that means watching three things: vendor-fee structures (Corpay monetizes payment volume), roadmap attention to construction-specific features, and customer-support investment post-privatization. Worth pricing into any multi-year contract.
AvidPay monetizes the vendor side of the payment — common public figures include ~1.2% on ACH and percentage-based virtual-card fees, varying by tier. Vendors pay to get paid faster, and the friction usually flows back to the GC as a relationship complaint. CheckIT doesn't touch payments, so we don't charge vendors anything — that's a structural difference in business model, not a promotional discount.
On a per-engagement basis, yes — but it's the wrong question. CheckIT is a per-document or per-engagement spend that pays back on document one if it catches a single material overbilling. AvidX is a quote-based annual subscription plus transaction fees that you'd buy for routing throughput. They're priced for different jobs, and most GCs end up paying for both because they're solving different problems.
