# What should I be aware of before and after importing invoices in Zoho Billing?

### Before importing invoices:

*   If the importing invoice file has a new customer then a new customer will be created with the same name in Zoho Billing.
*   If the Item code field is used then it should contain either the Plan Code or Add-on Code.

### After importing invoices:

*   If you’ve imported invoices with Auto generate invoice number turned off then head to the Invoice Preferences section and change the Next Invoice Number to a number higher than all the imported invoices.
