When organizations purchase third-party software through AWS Marketplace using annual subscriptions, they typically receive meaningful discounts compared to hourly pay-as-you-go (PAYG) pricing. However, when these annual subscriptions expire without active renewal, billing automatically reverts to the default hourly PAYG rate — which can be substantially higher. This is not a renewal at a higher rate; it is the absence of a renewal action that causes the subscription to lapse and the costlier pricing tier to take effect. Because the subscription simply expires silently, many teams do not realize they have lost their discounted rate until the cost increase appears in the next billing cycle.

This inefficiency is especially difficult to manage in enterprise environments where multiple Marketplace subscriptions are purchased at irregular intervals throughout the year, each with its own expiration date. Private offers — which provide custom-negotiated pricing — add further complexity because they cannot auto-renew by design; when a private offer expires, the customer either moves to the product's higher public pricing or loses the subscription entirely. The financial impact can be severe: in some cases, the licensing cost at PAYG rates can exceed the cost of the underlying compute infrastructure itself, as commonly seen with enterprise software such as SUSE Linux for SAP workloads.

Additionally, for AMI-based products, annual subscriptions are tied to specific instance types. Changing instance types during the subscription period causes billing to revert to hourly rates for the new type, creating another avenue for unintended cost increases even before the subscription formally expires.
