Your ERP Records Invoices. CheckIT Verifies Them.
Sage 300 CRE is the construction system of record. CheckIT is the layer that verifies every invoice line against your contract — before it hits Sage AP.
CheckIT runs alongside Sage. Sage stays the system of record.
Quick verdict
What Sage 300 CRE does
Sage 300 CRE — formerly Sage Timberline Office — is the construction and real estate management system used by an estimated 59% of ENR Top 400 contractors. It is the financial backbone for tens of thousands of construction businesses across North America, covering AP, AR, GL, job cost, commitments, billing, payroll, and project management in one connected system.
- Construction-native accounting depth — job cost, commitments, retention, AIA billing
- Native AP invoice entry tied to jobs, cost codes, and commitments
- Commitment ledger tracks contracted value and remaining balance per PO / subcontract
- Configurable approval routing through reviewers before posting to AP
- Mature partner ecosystem — TimberScan, Stampli, hh2, Procore, dozens more
- Used by 59% of ENR Top 400 contractors per Sage
Sage 300 CRE is widely regarded as best-in-class on construction-native accounting. CheckIT is built to work alongside it, not replace it.
What CheckIT Invoice does
CheckIT is a line-item verification engine purpose-built for construction. Upload an invoice and point CheckIT at the contract, quote, rate sheet, or rolling 12-month historical baseline. CheckIT verifies every line — material, quantity, unit rate, description — and returns a dollar delta per line, in minutes instead of the better part of an hour.
- Line-item verification against contract, quote, or historical baseline
- Explainable dollar delta per line, ranked by severity
- Three verification modes: Quote, Rate Sheet, Rolling 12-Month
- 75% reduction in manual review time per document
- No ERP integration required — not to start, not to run it — upload a PDF
- Runs in front of Sage AP; verified data flows into your normal Sage workflow
CheckIT does not replace Sage AP. It verifies the line items before they get keyed into Sage.
Feature comparison
Sage records the financial truth. CheckIT verifies it first.
Sage 300 CRE's commitment ledger holds the contracted value of every subcontract and PO, but the native AP module does not compare an inbound invoice line's unit rate, quantity, or material description against the contracted baseline. That comparison — at the line level, with an explainable dollar delta — is the verification job CheckIT is built for. Sage records the financial truth; CheckIT verifies the invoice before it becomes that truth.
A mid-market GC running Sage 300 CRE with native AP entry and a mature approval workflow still pulls Controllers and PMs into manual line-by-line invoice checking — Sage automates posting, not verification. The unit-rate-vs-contract comparison is still happening in Excel after the invoice has cleared.
Anonymized Sage-shop scenario, CheckIT pilot intake
CheckIT runs in front of Sage AP: you verify the invoice with CheckIT first, then your validated, cost-code-ready invoice flows through your normal Sage AP entry, approval, and posting process. Sage stays the system of record. CheckIT is the verification layer that protects the numbers Sage records.
If you need the construction system of record — use Sage 300 CRE.
Sage 300 CRE owns construction-native accounting: job cost, commitments, retention, AIA billing, certified payroll, and GL in one connected system. If you do not have a construction ERP, or are evaluating one against Sage Intacct Construction, Sage's conversation is the right one to have.
If you need every invoice line verified against the contract — use CheckIT alongside Sage.
CheckIT runs in front of Sage AP. It compares each invoice line — unit rate, quantity, material, description — against the contract or rate sheet baseline, returns a dollar delta with an explanation in minutes, and hands the validated invoice off to your normal Sage AP workflow.
The cost of not verifying
Sage records what you tell it. The invoice line keyed into Sage AP is only as accurate as whoever checked it first.
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. Sage 300 CRE — common questions
No — CheckIT does not replace any part of Sage 300 CRE. It runs in front of Sage AP: you verify the invoice with CheckIT first, then your validated, cost-code-ready invoice flows through your normal Sage AP entry, approval, and posting process. Sage stays the system of record. CheckIT is the verification layer that protects the numbers Sage records.
Sage 300 CRE's commitment ledger holds the contracted value of every subcontract and PO, but the native AP module does not compare an inbound invoice line's unit rate, quantity, or material description against the contracted baseline. That comparison — at the line level, with an explainable dollar delta — is the verification job CheckIT is built for. Sage records the financial truth; CheckIT verifies the invoice before it becomes that truth.
Yes — that is the default setup. CheckIT is document-in / report-out today, so no Sage integration project is required — CheckIT runs fully standalone. Upload an invoice, get a verified report in minutes, and key the validated line items into Sage AP through your normal workflow. A structured export back to Sage AP is on the CheckIT roadmap.
CheckIT runs in front of those overlays — it is not a replacement. TimberScan, Stampli, and hh2 automate invoice capture, OCR, coding, and approval routing into Sage AP. None of them compare invoice lines against the contracted unit rate at the line level. CheckIT handles that verification step before the invoice enters the overlay-to-Sage pipeline.
CheckIT is per-document or per-engagement — closer to an audit tool than an ERP module. There is no partner-led SOW, no per-user license, and no multi-month implementation. The first verified document is delivered in minutes; ROI is measurable on document one.
