Can somebody tell exactly how domains are selected for the sync cron? The documentation at https://developers.whmcs.com/domain-registrars/domain-syncing/ states:

I don't like to enable "Sync Next Due Date", due to some complications with my registrar module and the fact how we invoice our customers.

But from my observation it seems that domains are only synced if they are close to their "due date", is that correct?

if memory serves, they are just synced in domain ID order... and unrelated to expiry dates... though maybe that has changed in recent versions - though I don't use Domain Syncing.

@brian! is correct it runs on Domain ID number for syncing

But expired domains are not included in the cron?

If so, can I change that?

That is correct. Only Active domains are included. There is no way to change the WHMCS supplied cron to sync expired domains. You could however update the domains status and then the sync will obtain the data for you.

i'd recommend periodically checking your expired domains, either via clients -> domain registrations and filtering for "Expired", or by running the Domains report.... if you spot any that are expired that shouldn't be, you can change their status to Active and they would then be available to the domain sync script to synchronise.
