# Import your client list

Description: Bring your client book from Fresha, Square, Booksy, Vagaro, or any spreadsheet. Map the columns, import, undo within 7 days if needed.
Updated: 2026-08-09

Switching software shouldn't mean starting your client book from zero. Export a CSV from your old system, upload it, and your book arrives intact.

## What you'll need

A CSV export of your clients. Every booking platform has one:

- **Fresha**: Clients → export.
- **Square**: Customers → Import/export → Export.
- **Booksy**: ask their support for a client export.
- **Vagaro**: Reports → customer list export.
- Or any spreadsheet saved as CSV with a header row: name, email, phone.

## Import it

1. Go to **Clients** and click **Import** (owners only).
2. Upload the CSV, up to 5,000 rows.
3. Check the column mapping. Rezzy auto-detects the usual headers; fix any it guessed wrong, and skip columns you don't want.
4. Choose what to do about **text/marketing consent**: default is imported clients start unconsented, which is the safe choice unless your export has a real consent column.
5. Review the preview, then confirm.

*Rezzy guesses the mapping from your headers; you confirm before anything imports.*

Nothing imports until you confirm the mapping, and the whole import can be undone for 7 days.

## How Rezzy handles your data

- **Existing clients are matched by email** and never overwritten: a match only fills in blanks, like a missing phone number. Your one source of truth stays true.
- New clients arrive tagged **imported**, so you can filter them.
- **Nobody gets emailed.** Importing is silent; no welcome messages, no marketing, nothing leaves the building.

## If it went wrong

Open the import result page and click undo. Imported clients are archived; anyone who has booked since stays put. Then fix the CSV and run it again.

Leaving is just as easy as arriving: [export your client list](/guides/export-your-client-list) any time, on any plan.
