Rex Cash Application
What Rex Cash Application is
Rex Cash Application is an accounts receivable service for enterprise finance teams. It monitors incoming payments that remain unallocated, then matches remittance details with invoices, customers, and open balances. When it detects deductions, underpayments, short payments, or unexplained differences, it can request more payment information and route uncertain matches, disputes, or write-off decisions to finance. Before month-end close, Rex summarizes unallocated cash and reconciliation blockers. It supports automatic posting and exception workflows, with actions available for review before execution; each action includes a trace of its rationale and inputs. Rex says it connects with ERPs, CRMs, email, and Microsoft Teams, and names NetSuite, QuickBooks, and Sage in its ERP article. The service runs on AWS, supports enterprise SSO, and is pursuing SOC 2 Type II certification. Rex says customer data is not used to train or fine-tune models or shared across tenants, and that it deletes customer data within 30 days of a termination request. Pricing is outcome-based, tied to work its agents complete, with fees benchmarked against the cost of operating receivables. Rex says implementation is typically live in under two weeks.
