Determine invoice name

I have the following trigger that inserts an Invoice as a related object to the Contact.  The Invoice has a number field that is auto-generated.  Is there a way to code this so that the each Invoice will have the name "Invoice" plus it's number (0001, 0002, etc.)?

trigger contactGenInvoice on Contact (after insert, after update) {
    List<Invoice__c> invoiceList = new List<Invoice__c>();
    for (Contact con : Trigger.new) {
        if (con.Status__c == 'Inactive') {

            Invoice__c i = new Invoice__c();

            i.Name = 'Invoice ';
            i.Date__c = System.today();
            i.Amount__c = 100;
            i.ContactId__c = con.Id;

        insert invoiceList;

Hi Robert,

You can try using workflow to update Invoice Name with Name + AutoNumber.

If "Criteria:- ContactId__r.Status__c ='Inactive'" is true then make field update on Name field.

Formula Value: Name&' '&Auto_Number__c.

Hope above information was helpful.
