AI Agents That Parse Invoices and Purchase Orders from Gmail

AI agents fetch PDFs and images straight from Gmail and Drive, extract every field with OCR + LLM parsing, and write clean structured data to Sheets - without anyone touching an inbox.

Invoice Automation

Automated Invoice Generation Across QuickBooks, Xero, and Thinkific

Orders and estimates turn into invoices automatically - no one manually finds a price, retypes a line item, or opens QuickBooks to create a bill.

Payment Reconciliation Across Stripe, PayPal, and Zoho
Payment Ops

Payment Reconciliation Across Stripe, PayPal, and Zoho

Webhooks catch every payment the moment it lands and match it back to the right invoice - no one logs into Stripe or PayPal to check what's been paid.

Invoice Correction and Dispute Management with AI Agents
Dispute Management

Invoice Correction and Dispute Management with AI Agents

When a bill is wrong - overbilled, underbilled, or disputed - an AI agent reads the time entries, compares them to the invoice, and fixes it in Xero automatically, with a Slack alert either way.
