Importing customer data from another system

How to import customers and appointments from a CSV file.

2 min read

What can you import?

The customer list with its import button

The import lets you bring in:

  • Customers: name, email address and phone number
  • Appointments: attached to customers you already have, or to new ones

Go to Settings > Import (or through the Import shortcut in the menu).


Step 1: Prepare your CSV file

The customers CSV

Required columns: name, email Optional: phone

Use UTF-8 encoding and either a comma or a semicolon as the separator.

The appointments CSV

Required columns: customer-email, service, date, time, duration

Check that the service names match exactly how you created them in Stippa.


Step 2: Upload the file

Upload your customers CSV, your appointments CSV, or both, on the import screen.


Step 3: Check the preview

Stippa shows you the first few rows. Check that the columns were recognised correctly. Errors are reported row by row.


Step 4: The overlap setting (appointments only)

When importing appointments, you decide what should happen when a slot is already taken:

  • Strict: overlapping rows are skipped
  • Allow: overlapping appointments are created anyway

Step 5: Import

Click Import. Afterwards you get a summary of how many rows went through and how many failed. You can download the failed rows as a CSV, correct them and import again.


Existing customers are not duplicated

If an email address already exists in Stippa, the existing profile is updated. No duplicate is created.


Can I undo an import?

No. Check the preview carefully before importing. If something does go wrong, you can delete customers by hand under Customers > [customer] > Delete.
