Features

Multi-Account

Connect to multiple NetSuite accounts with OAuth 1.0 TBA. Switch between production, sandbox, and client accounts.

Saved Queries

Define reusable query templates with field selection and filters. Each query maps to its own worksheet.

Bidirectional Sync

Pull records into Excel tables, edit cells naturally, then push creates, updates, and deletes back to NetSuite.

Smart Change Detection

Hash-based snapshot diffing detects exactly what changed. Only modified rows are sent to NetSuite.

Governance-Safe

Automatic batch splitting respects NetSuite's 5,000 unit governance limit. Real-time progress tracking.

Zero Infrastructure

OAuth signing happens directly in the add-in. No proxy servers, no middleware, nothing to deploy or maintain.
