Full-Stack Checkout Building with Cline

Tell your VS Code agent to build a new billing component, and it handles the entire Avalara integration. It writes the frontend form, sets up the API routes, and implements `create_transaction` to calculate live sales tax based on cart totals. The agent doesn't stop at scaffolding. It creates the test files, mocks the responses, and verifies the tax logic works by running `get_account_check` to confirm the backend talks to Avalara correctly.

Location Validation and Rate Lookups

Hardcoding tax rates is a massive liability. Cline fixes this by wiring up `get_tax_rates_by_address` to fetch real-time percentages for any physical location your customers enter. Before calculating those rates, the agent ensures the location actually exists. It implements `resolve_address` in your backend controllers to catch typos and format issues before they hit the checkout database.

Transaction Lifecycle Testing via MCP Server

Writing integration tests for payment processing requires managing state. Instruct the agent to build a test suite that creates an order, verifies the tax, and then uses `commit_transaction` to finalize it. To prevent test bloat in your Avalara dashboard, the agent writes teardown scripts. It fetches the test records via `get_transaction` and executes `void_transaction` to wipe them out completely.
