Invoice collaboration and exceptions
Stampli
Stampli is an invoice-centric AP platform built around approvals and collaboration. Its distinguishing feature is putting communication and approval context directly on the invoice, so the person deciding sees the full history.
It is often used where invoice exception handling and coordination are the main pain points, and it is commonly evaluated for ERP and accounting integrations. Fit: teams whose bottleneck is approvals and exceptions rather than raw invoice volume.
