AI agents that run document-heavy business processes end to end
Agents read invoices, POs, remittances, claims and forms, then act on them — matching, approving and posting rather than only extracting fields.
Clean, validated data is written directly into systems of record including SAP, Salesforce, NetSuite, QuickBooks and Gmail workflows.
Policies, SOPs, system data and conversation history are stored as a governed graph so every agent decision cites the rule and document behind it.
Prebuilt flows for accounts payable, reconciliation, order management, cash application, supplier onboarding and claims processing.

AI invoice processing and AP automation for finance teams
LLM-driven OCR captures invoice headers, line items, and tax details automatically, cutting manual data entry on vendor-based and service-based invoices.
Automated rules check extracted data before it moves on, reducing the validation effort that typically consumes AP team hours.
Route invoices to the right approvers based on organization-defined rules, with visibility into each queue and workflow stage.
Interactive dashboards track outstanding payments, vendor activity, and financial data so finance leaders can act on real-time insight.
