Works with Sage
Keep Sage. Add the check before it posts.
Sage 100 Contractor and Sage 300 CRE stay your accounting system of record — job costing, the commitment ledger, AP, all of it. CheckIT sits in front of AP: it reads the invoice against the quote or subcontract line by line and flags what doesn't match before you post it. No integration to set up — drag in the invoice and the quote, and CheckIT does the check in about five minutes.
5-minute setup · No integration required · Sage stays exactly where it is
Sage 300 CRE's commitment ledger matches invoice totals to committed subcontract and PO amounts at the document level, and Sage 100 Contractor's AP module works the same way — neither checks individual line items, unit prices, or quantities against the original quote. That line-by-line verification happens outside Sage, typically in Excel or on paper, after the invoice is already in the system. CheckIT does that check before the invoice posts, without replacing Sage.
Two different jobs. One clean split.
Sage owns
- Job costing
- The commitment ledger for subcontracts and POs
- Accounts payable
- General ledger and financial reporting
CheckIT owns
- Line-by-line invoice verification
- Price and quantity checks against the quote
- Flagging charges never quoted
- One-click dispute drafts
Connecting the field to Sage AP
The crew and the field team run on Procore or another field tool. The books run on Sage. Nobody upstream is checking line items against the quote before the invoice hits AP — CheckIT does that today by drag-and-drop, with a direct connection to Sage on the roadmap.
A direct connection to Sage 100 Contractor and Sage 300 CRE is on the roadmap, built on CheckIT's unified ERP connection layer. Until then, CheckIT works alongside Sage today via drag-and-drop — no IT project required. See all integrations
Where it fits
Stacks we see every week.
Procore up front, Sage in the back
Procore tracks the job in the field — budgets, submittals, change orders. Sage 300 CRE holds the commitment ledger and runs AP. Invoices get matched to the PO or subcontract total, but nobody checks unit prices and quantities against the quote line by line — that gap is where CheckIT sits, before the invoice posts.
Sage 100 Contractor, no PM layer
Smaller GCs and heavy trades running Sage 100 Contractor often skip a separate PM tool — POs and invoices go straight to the office. Native AP matches the invoice total to the PO, but line-by-line price and quantity checks against the quote still happen in Excel or a binder, after the invoice is already paid. CheckIT runs that check before it posts.
Questions, answered.
Not yet — a direct connection to both Sage 100 Contractor and Sage 300 CRE is on CheckIT's roadmap, built on a unified ERP connection layer. Today, CheckIT works alongside Sage with no integration: drag in the invoice PDF and the quote or subcontract, and CheckIT checks them line by line in about five minutes.
No. Sage stays your accounting system of record for job costing, the commitment ledger, AP, and financial reporting. CheckIT doesn't touch any of that — it adds a line-item check on invoices before they get entered, then gets out of the way.
Sage 300 CRE's commitment ledger is built to hold the contracted value of subcontracts and purchase orders, and its AP matches invoice totals against those commitments at the document level. It isn't built to compare individual line items, unit prices, or quantities against the original quote — that's a separate check most teams still do by hand.
No IT project and no Sage administrator access required. CheckIT runs as a drag-and-drop tool: upload the invoice and the quote or subcontract, and it flags the differences. Setup takes about five minutes and doesn't touch your Sage database.
Yes. CheckIT works the same way regardless of which Sage product runs your books — it checks the invoice against the quote or contract before the invoice is entered, independent of the accounting system on the back end.
