Verification in. Verified data out.
Everything CheckIT's tools do runs through the engine's API — the same one we build on. Documents and data flow in; verified, line-item, source-traceable results flow out. If you're a platform that moves construction financial documents, or an enterprise with its own stack, the engine can sit inside your workflow.
In: documents and baselines, however they exist.
Documents
Invoices, quotes, bids, contracts, change orders, delivery tickets. PDF, image, spreadsheet. Scanned, photographed, or born-digital.
Baselines
Contract terms, rate sheets, cost code lists, committed values — pushed programmatically or synced from connected systems.
Events
Webhook ingestion from connected platforms, normalized into the engine's event model.
Out: line-item truth, with receipts.
Verification results
Every line compared against every relevant baseline: matched, flagged, or missing. Each flag carries the dollar impact and a pointer to the exact source line.
Structured line-item data
Normalized quantities, unit prices, cost codes, tax treatment — extraction as a byproduct of verification.
Approved-payable payloads
Verified invoices formatted for accounting systems, per-line cost coding intact (this is what powers the QuickBooks integration).
Deterministic and auditable
Results are computed, not predicted. The same inputs return the same outputs, every time. Your auditors will like that. AI reads the documents; math does the verdicts.
Built on it ourselves. Opening it deliberately.
The API is how CheckIT's own tools work — it's production infrastructure, not a side project. We're opening it in stages: platform partners who move construction financial documents, and enterprise customers whose volume justifies direct integration. Self-serve developer access comes later; being early in the partner queue is how you shape it.
Not a developer? The tools are the easy way in.
Drop an invoice and a quote into CheckIT Invoice — every difference flagged in minutes. It runs on the same engine the API exposes.
