Which Sume credits are spent first: included usage, top-ups, grants

Sume spends subscription-included usage first, then top-up credits, then operator grants, signup credit and legacy credit. Within each group the lot that expires soonest is used first. The point of the order is that the credit most likely to vanish goes before the credit you paid extra for. Included usage figures come from Sume's plan catalog; the Billing and subscription page in the dashboard shows what is left on your workspace.

The order

Credits sit in one pool that generation, the Agent, Formats and the API all draw from. Each source is a separate lot with its own expiry.

A worked example with made-up balances

Suppose a Pro workspace has $6.00 of included usage left, a $50.00 top-up lot and nothing else. An 8-second Wan 3.0 clip at 720p costs $1.00. The first six clips drain the included $6.00. The seventh draws from the top-up, leaving $49.00. Next month the included usage renews to the plan amount and is spent first again, so the top-up sits untouched until a month's work exceeds the allowance.

That is why a top-up on a busy plan is a buffer rather than a second subscription. It only moves when included usage is gone, and it lasts up to 365 days from purchase.

What to check

Two practical consequences follow. First, unused included usage disappears at period end, so a plan you rarely use costs its full fee. Second, a job reserves credit at submit and the reserve follows the same order, so a queued job can show a lower balance before it runs; read how the reserve works.

Top-ups are team-wallet only, so a solo workspace may need to look at the top-up limit. Expiry details for top-up lots are in the 365-day post.

The order has one more practical effect for teams that share a workspace. Because included usage is spent first, the plan's allowance goes to whoever runs jobs early in the month, and a top-up bought for a big project is only touched once that allowance is gone. The Billing and subscription page in the dashboard is the place to check which lots are left.
