How it works

A detailed step by step guide about how Versori functions

1. Describe your systems

Agent connecting to API spec, database, and CSV or JSON sources

Provide the agent with your OpenAPI spec, GraphQL endpoint, database schema, or sample CSV/JSON export.

2. Build and test with AI agents

The agent maps fields to Avalara's data model, writes integration logic, and runs real test transactions against the tax calculation engine.

3. Review and deploy

Inspect every mapping decision, sign off with a complete audit trail, and deploy the production-ready integration.
