The invoices that only have $0 line items can be suppressed from getting generated using the option "Hide Zero Value Line Items" under Settings > Site Settings > Site Info & Billing Rules in the web interface.
Here's a screenshot for reference:
Note - In case credits and discounts are added to an invoice, bringing the total payable amount to $0, the invoice will still be generated.
