Construction already has software.
Documents, procurement, ERP, accounting, the tools exist. ClaimStack connects them, so commercial information stops moving by hand.

Accounting & ERP
Push the truth downstream
Approved claims, invoices and commitments flow to Xero, MYOB and your ERP, no double entry, no reconciliation guesswork.
Documents
Bring the paper trail in
Connect Procore, Aconex and email so a commercial event carries its evidence, not a link someone has to go chase.
AI & MCP
Open to your assistants
An MCP layer lets approved AI read live commercial context. Bring your own model, your data stays yours.
Data & export
Nothing locked in
API access and clean exports. Your commercial record is portable, reporting, BI, or whatever comes next.
Humans shouldn't be the integration layer.
Every manual re-key is delay, duplication and risk. ClaimStack becomes the connective tissue, the systems keep their jobs, the people stop being the wiring.
Connect your
stack.
