Importing customers, stock and compliance records

The CSV wizard: what imports, how column mapping works, and the preview that saves you.

Getting started · 23 August 2026 · 3 min read

Three things are worth importing when you arrive: your customers and their sites, your stock list, and your compliance register. Everything else starts better fresh.

How the wizard works

  • Export a CSV from your old system or spreadsheet. Any reasonable column layout works.
  • The wizard maps your columns to Onyx One's fields and lets you correct it.
  • You see a preview of exactly what will be created before anything commits.

What not to import

Finished jobs and old invoices. Xero stays the source of truth for your accounting history, and a half-imported job history is worse than a clean start. The moving guide covers the full order of operations.

A weird export from a system that makes leaving hard? Email support@onyx1.app and a person who built the importer will help you shape it.
