# Can we make ServiceM8 job numbers the same as Xero invoice numbers?

By default, ServiceM8 job numbers become the invoice number in Xero, so yes, your reference number for a single job/invoice will be the same in both ServiceM8 and Xero. This is configured in Settings > Preferences > Invoicing > Xero invoice number.
