A new invoice after a payment has been made on it

I have a suggestion on how to handle your customer's invoice, @roberta14.

I'm here to help you generate with new invoice number for your customer. This way, they can pay you with less hassle and on time. 

You can automate repetitive invoices by creating an unscheduled recurring transaction in QuickBooks Online. Let me show you how:

1. Go to the Gear icon and choose Recurring transactions under Lists.
2. Select the New tab, then pick Invoice as the Transaction Type and hit OK. 
3. Add a Template name and select Unscheduled in the Type drop-down. 
4. Complete the Customer, Email, Interval, Product and services fields. 
5. Click Save Template. 

You can then use that template the next time you need to send an invoice to that specific customer. Just click the Use under Action. See the sample screenshot below for reference: 

In addition, if you have time, I recommend visiting this link to learn how Quickbooks' progress invoice feature works: Set up and send progress invoices in QuickBooks Online. Presumably, you can use it in future transactions.
