Popular use cases
Payment Status Inquiries via WhatsApp
A customer messages on WhatsApp asking about a recent payment. Your agent instantly accesses Mercury MCP to view transaction history and balances, confirming the payment was received and processed. The agent responds immediately with accurate details, resolving the inquiry in seconds rather than requiring a callback or email follow-up.
Invoice and Statement Requests
Clients request copies of statements or transaction summaries through your chat or email channel. Agents can retrieve this data from Mercury MCP and share it directly in the conversation, reducing back-and-forth delays. This is especially valuable for accounting inquiries in professional services, healthcare billing, or logistics payment verification.
Fraud or Dispute Resolution
A customer disputes a charge or reports suspicious activity. Support agents can pull transaction details from Mercury MCP in real-time to investigate, confirm legitimacy, and escalate if needed—all within the Saysimple inbox. This speeds up resolution and builds customer trust by showing you have immediate access to accurate financial records.
