Re-generate invoice on product/service billing frequency change

When a product/service's billing frequency is changed, say from monthly to quarterly, etc...the system doesn't always auto create invoices at the new interval (or at all).

Please fix this.

Hi Peter,
Thanks for making this suggestion.

At present if an invoice has already been generated for this service on the current Next Due Date, a second invoice would not be created. If you need to generate a new invoice, I suggest moving the Next Due Date back by 1 day.

This will allow the system to generate a new invoice with the new service Recurring Amount and Billing Cycle: https://docs.whmcs.com/Billing_Logic#Renewal_Invoices

Thanks John,

We've experienced new invoices no longer being created after changing the frequency of a recurring product/service.

You've got to delete the original product/service and re-create it with the new frequency (monthly/quarterly/annually, etc...).

Hi Peter,
It is not necessary to delete the service and re-create it, just move the Next Due Date to an uninvoiced date for the service.
