Quick Answer

Connect Ramp MCP to Zapier, use Claude to categorize each transaction based on merchant and amount, and sync results to QuickBooks. Daily automation means expenses are always current without manual entry.

The Problem This Solves

Manually categorizing dozens or hundreds of corporate card transactions each week is tedious and error-prone. This workflow handles routine categorization automatically, leaving only unusual transactions for human review.

About This Workflow

This workflow connects to your Ramp corporate card account via Ramp MCP, pulls new transactions daily, sends them to Claude for intelligent categorization based on merchant name and transaction details, and syncs the categorized transactions to QuickBooks or Xero. Claude learns from your existing category patterns by including recent examples in the prompt, improving accuracy over time without manual configuration.
