AFAIK, your distributor is mixing two different concepts: license type (perpetual vs subscription) and payment structure (upfront vs annual billing).
SQL Server Standard 2022 2-Core License Pack is traditionally a perpetual license when sold under volume licensing or CSP perpetual programs. “Perpetual” means the customer owns the license rights indefinitely for that version (subject to licensing terms). However, perpetual licenses can still be paid in installments under certain purchasing programs.
The phrase “3 year billed annually” does not automatically make it a perpetual license. That wording is typically used for subscription licenses under programs like CSP (Cloud Solution Provider) where the customer commits to a 3-year term but pays annually. In that case, it is a term subscription, not perpetual. When the 3-year term ends, the right to use the software ends unless renewed.
If it is truly a perpetual license with Software Assurance (SA) for 3 years, then what the customer is paying annually is usually the Software Assurance component, not the license itself. In that structure, the base license is perpetual, and SA provides upgrade rights and benefits during the 3-year coverage period. Even if billed annually, the license does not expire when SA ends - only the SA benefits do.
The key distinction is this: if the SKU is a “subscription” SKU, usage rights end after 3 years unless renewed. If it is a “perpetual + 3 years SA” SKU, the license remains forever, but upgrade rights and benefits stop after 3 years.
The end user does not necessarily have to pay the entire 3-year amount upfront if the agreement states “billed annually.” That wording normally means they are invoiced once per year over a 3-year commitment term. However, they are still financially committed to the full 3-year term unless the contract allows cancellation.
To resolve this definitively, you need the exact Microsoft SKU number or confirmation of whether this is CSP Subscription, CSP Perpetual, Open Value, or another licensing program. The licensing program determines whether it is perpetual ownership or a 3-year term subscription.
