Invoice Generation via API is a private, internal-use integration operated by Essntl Ltd. It connects the company's own QuickBooks Online account to an AI assistant (via the open-source QuickBooks Online MCP Server published by Intuit) so that authorised staff of Essntl Ltd can read and manage their own accounting records — customers, invoices, bills, vendors, items and accounts.
The app is not offered to the public and is not listed on the QuickBooks App Store. It is used exclusively by Essntl Ltd on its own QuickBooks Online company.
