Helping Subs Get Paid vs. Helping GCs Avoid Overpaying
Siteline helps subcontractors assemble pay apps, collect lien waivers, and get paid faster. CheckIT helps the GCs and owners on the other side of those invoices verify what's being billed against what was contracted — line by line. Opposite sides of the same envelope. Both can run on the same job.
Different parties, same transaction.
Quick verdict
What Siteline does
Siteline is the category-leading pay-app and A/R platform for commercial trade subcontractors — mechanical, electrical, plumbing, drywall, glazing. Its edge is a library of 15,000+ custom GC billing forms mapped to 10,000+ general contractors, so a sub working multiple GCs doesn't re-template anything.
- AIA G702 / G703 pay-app generation against any GC's custom format
- Conditional / unconditional, partial / final lien waivers — state-specific, lower-tier vendor collection automated
- Schedule of values tracking with current period, retainage, balance-to-finish columns standard to AIA
- A/R dashboard with days-to-pay tracking by GC + accounting / GC-portal integrations (QuickBooks, Sage Intacct, Sage 300 CRE, NetSuite, Foundation, Textura, GCPay, Procore Pay)
With $18.4M raised from Menlo, Brick & Mortar, and First Round, Siteline is widely regarded as best-in-class on the subcontractor side of construction billing.
What CheckIT Invoice does
CheckIT lives on the other side of the same envelope. When that pay app arrives at the GC, somebody has to verify it. CheckIT reads every line — material, quantity, rate, unit, extension — and compares it against the contract baseline, the rate sheet, or rolling 12-month historical pricing. The output is an explainable, dollar-quantified report.
- Line-item verification against contract, quote, or rate sheet — every line, every time
- Explainable dollar delta per line, severity-ranked, audit-ready
- Three verification modes: Mode A (Quote → Invoice), Mode B (Rate Sheet), Mode C (Rolling 12-Month Historical)
- 75% less review time per document, no ERP integration, no 60-day rollout

Feature comparison
Two different jobs. Same invoice.
A construction invoice is a two-sided document. On one side, a subcontractor assembles it, makes sure the SOV math is right, attaches the lien waiver, and sends it for payment. On the other side, the GC opens it and tries to decide whether what's being billed actually matches what's been delivered against what was originally contracted.
Siteline owns the first job decisively — the 15,000-form library is a real advantage, and the A/R dashboard and waiver automation make a coherent product built around one persona's pain. CheckIT lives on the other side of that envelope. When a Siteline-generated pay app lands at the GC, somebody still has to verify it line-by-line. That's the verification gap nobody else closes — 39% of construction invoices contain at least one error.
Subs use Siteline to bill us correctly. We use CheckIT to make sure we're paying for what was actually delivered. Both products on the same job, both parties leave the closing table cleaner.
Anonymized mid-market GC, $80M revenue, three active CheckIT pilots
If you need to bill cleanly, use Siteline.
You're a commercial electrical, mechanical, plumbing, drywall, or glazing sub doing $10M–$200M and you submit pay apps to a dozen GCs every month. The pain is form-by-form re-templating, lien waiver chasing, and not knowing where your A/R sits. Siteline's 15,000-form library and A/R dashboard solves that cleanly.
If you need to verify what's been billed, use CheckIT.
You're a mid-market GC, industrial owner, or PMC firm approving invoices from a dozen subs across multiple projects. You suspect line items are creeping above the original contract. You don't need a workflow tool — you need a verification tool that hands you a defensible dollar delta in minutes.
On a single job, both can run.
The mechanical sub uses Siteline to assemble a clean AIA G703. The GC's PM uses CheckIT to verify the line items against the original bid before approving. Co-existence is the right answer, not the compromise.
The cost of not verifying
Every unverified invoice is a bill paid on trust. These are the numbers behind why CheckIT exists — and why it complements (not competes with) Siteline on the other side of the same job.
Across the trades, 39% of construction invoices contain an error.

CheckIT vs. Siteline — common questions
No — Siteline is purpose-built for the subcontractor side of the transaction. It helps subs assemble pay apps in any GC's format, attach lien waivers, and track A/R. It doesn't verify line items against a GC's contract baseline, because that isn't the job it was built for. CheckIT handles that side.
Yes — and that's the ideal handoff. The mechanical sub uses Siteline to generate a clean AIA G703 with the correct lien waiver. The GC's PM uses CheckIT to verify the line items against the original bid before approving. Both products on the same invoice, both parties protected. They don't conflict.
Siteline helps subcontractors get paid. CheckIT helps GCs and owners avoid overpaying. They sit on opposite sides of the same invoice — different parties, different jobs, different software categories. Most jobs need both.
No. CheckIT runs document-in / report-out. Upload a PDF, get a verified, dollar-quantified report in minutes. No Sage, Acumatica, Vista, or Procore integration required — though it's available for customers who want it.
The pricing models aren't comparable — Siteline is a quote-based subscription scaled to a subcontractor's billing volume; CheckIT is per-document or per-engagement on the GC side. Since both products serve different parties on the same invoice, the more useful question is ROI per document, where CheckIT pays back on document one — 39% of construction invoices contain at least one error.
