## Before you start
You need their email address. Everything else is optional. It takes about a minute.

## Add one customer
1. Click **Customers** in the left rail.
2. Click **New customer**.
3. Type the email. Add first name, last name and phone if you have them.
4. Type a note in **Notes** if you want one saved with the record.
5. Click **Add customer**.

The note appears on the **Notes** tab of the new record.

## What happens with duplicates
yaya matches on email first.

- **Same email.** The customer already exists. The panel offers an **Open** button with their name. It opens the existing record and creates no second one.
- **Same phone, different email.** The panel shows who has that number. Click **Add anyway** if the shared number is right, for example a family or a shop line. Phones match by digits only, so `+1 (415) 555-0199` and `4155550199` are the same.

## Fix common problems
**The Add customer button is grey.** The email field is empty.

**"Could not add the customer."** Check the email format and try again.

**I added the wrong person.** Open the record, click the three-dot button, then **Delete**.
