Do Sume wallet credits expire? 365 days per top-up lot

Short answer: yes, but slowly. In the Sume code, every Stripe top-up is written as its own credit lot, and each lot expires 365 days after it is credited. The team wallet view shows the date of the next lot to expire. The public docs page on billing and credits describes manual top-ups but does not state the expiry, so treat the dashboard as the final word on your own lots.

What 365 days means in practice

If you buy a $100 top-up on October 5, 2026, that lot is good until October 5, 2027. A second $100 top-up on March 1, 2027 is a separate lot with its own date. You do not have one balance with one clock; you have a stack of lots, and the oldest one is the first to lapse.

Manual top-ups run from $10 to $1,000, with presets of $50, $100, $500 and $1,000, and one credit is one dollar. That range is on the pricing page FAQ, which says teams can fund a shared wallet from $10 to $1,000.

Sizing a top-up so nothing lapses

The simple rule is to top up no more than you expect to spend in about a year. The arithmetic is short:

• Estimate monthly spend. A creator rendering ten 5-minute Timeline videos a month pays $0.10 per output minute, so about $5.00 a month in renders before any generation.
• Multiply by 12. At $5.00 a month that is $60 a year, so a $100 lot would be larger than a year of render spend alone.
• Add generation. Voice at $0.0475 per 1,000 characters and a $0.125 music track each are small next to image and video models, so run an estimate for your real mix before choosing the lot size.
• If the number lands under $10, the $10 minimum is your lot, and it still has a year to run.

How this differs from monthly credits

Some video tools reset allowances every billing period. On the page read today, InVideo lists plans with a fixed number of credits per seat and states that credits do not roll over monthly. That model rewards using everything before the date; it is a different bargain from a wallet where unspent dollars stay for up to a year.

The trade is the reverse risk. A monthly allowance can never be wasted for longer than a month, while a large top-up bought for a single campaign can sit unused and lapse. If you are unsure, buy the $50 or $100 preset and top up again when the balance runs low.

What to check before you rely on it

• Open the team wallet in the dashboard and read the next-expires date after each top-up.
• Remember that top-ups pay for usage; they do not raise concurrency, which is set by your plan only.
• Read your balance from the API with GET /v1/balance, which is a read-only call; creating a top-up is a dashboard action.
