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 — CheckIT verifies what Siteline delivers.
Different parties, same transaction.
Quick verdict
What Siteline does
Siteline is a pay-app and A/R platform for commercial trade subcontractors — mechanical, electrical, plumbing, drywall, glazing. It offers 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)
Siteline serves the subcontractor side of construction billing. Original-invoice verification against a GC's contract baseline isn't part of that build.
- Whether the rate, quantity, or unit on a billed line matches the GC's contract, quote, or rate sheet
- Rate-sheet or rolling 12-month historical price baselines behind what's billed
- Dollar-quantified, severity-ranked discrepancies per line
- Anything once the pay app is generated — assembly and delivery is the job, not verification against the contract
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
Siteline assembles the pay app. CheckIT verifies what's on it.
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 handles the first side — the 15,000-form library and the A/R dashboard and waiver automation cover pay-app assembly for the sub. 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 Siteline: a commercial trade sub billing a dozen GCs a month.
You're doing $10M–$200M in mechanical, electrical, plumbing, drywall, or glazing work, and the pain is form-by-form re-templating, lien waiver chasing, and not knowing where your A/R sits. That's a billing-assembly problem, and Siteline's 15,000-form library and A/R dashboard are built for it. It still leaves open whether the lines you're billing match the GC's contract — that's the question on the other side of the envelope.
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.
What this looks like in your trade
Siteline works your revenue side — billing the GC. CheckIT works your cost side — what suppliers bill you.
Electrical
While you're assembling pay apps for the GC, your suppliers are invoicing you for wire and gear that repriced since the bid. CheckIT checks those cost-side invoices against the quote — margin has two ends.
CheckIT for Electrical ContractorsPlumbing
The pay app going out is only half the month. The supply-house invoices coming in carry the billing errors — CheckIT checks them against the quote you bid from, in minutes.
CheckIT for Plumbing ContractorsPainting & Finishes
Materials look simple until the invoices land — coatings repriced, quantities rounded, delivery fees nobody agreed to. CheckIT checks each line against the quote before you pay.
CheckIT for Painting & Specialty Finish Contractors
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.
