One-time payment web hostingproviders typically handle software updates and maintenance on a case-by-case basis. Since these plans involve a single upfront payment, ongoing support and updates may not be as frequent or extensive as with subscription-based plans. Some providers might include basic updates and maintenance as part of the service, while others may offer these as optional add-ons. It's important to check the specifics with the provider to understand what level of ongoing support and maintenance is included in their one-time payment web hosting plans.
