German-language publisher in Australia seeks subscription and advertising management

We are a small newspaper publisher in Australia and are looking for subscription and ad management software for our German-language weekly newspaper.

For subscription management, it is important that subscriptions cannot be automatically renewed here. This means that each subscription customer must be asked to renew and pay again after the (maximum) one-year subscription has expired. This should be done largely automatically. The number of subscribers is in the high four-digit range.

In addition, it would be helpful if orders, sales, and payments from advertising customers could also be recorded.

An on-premises solution is desired.

Three to four software workstations are required.
