Dialpad Support
Customer experience shouldn't run on disconnected tools and static scripts. Dialpad Contact Center brings voice, digital channels, and human agents together in a single AI-native platform, built to act — not just record — on every customer interaction. This is Agentic AI in practice: agents that reason through a problem, take the next step, and drive it to resolution without waiting on a human to intervene. Where legacy systems leave data trapped in silos, Dialpad Contact Center closes that gap, linking voice and data so context travels with the customer instead of getting lost between systems. The payoff compounds. Dialpad has already generated over 775 million AI recaps, and each new interaction adds to a growing base of operational intelligence — sharper resolution paths, more productive agents, better outcomes quarter over quarter. None of it runs unchecked: Dialpad's Guardian layer keeps AI operations secure and governed, so intelligence scales without sacrificing oversight. In practice, that means up to 80% of issues get resolved autonomously, freeing your team to focus on the conversations that genuinely need a human. Intelligence works at the edge; people stay at the center of the experience. And you don't have to take the ROI on faith. Through Dialpad's Proving Ground, enterprises can validate performance and cost savings before rolling out at scale — a far more reliable path than betting on a brittle, rules-based bot.

Monk
Most enterprise invoices are never paid from an emailed invoice. Across the $2B+ in receivables Monk manages, 92% have to be submitted through the buyer accounts payable portal instead, and a failed submission is usually silent. Monk is an AI-native accounts receivable platform built around that problem. It files invoices into more than 600 corporate AP portals, including Coupa, Ariba and SAP Business Network, uploads 87% without a person, and brings each rejection back onto the invoice record with the reason attached. Collections runs on the same data. Julia, the Monk agent for Intelligent Collections, reads inbound replies and answers what the customer wrote instead of advancing a dunning schedule, clearing 90% of invoices without escalation. Outbound mail sends through your existing Gmail or Microsoft 365 mailbox. Payments match at 80%, rising to 95% once rules are added. Runs on QuickBooks, NetSuite or Dynamics 365 Business Central. SOC 2 Type II. Live in one to three days.
