Usage on BoxLite Cloud can be funded two ways: from a prepaid **wallet** alone, or from a **plan** whose included quota covers usage first and whose wallet picks up the rest. Which one costs less is arithmetic, and it turns on a single number — your monthly usage. ## How funding works **Quota covers first, the wallet funds the rest.** A box draws on this cycle's included quota until the quota is gone, and on your prepaid wallet balance from then on. An account does not have to carry a plan. With no plan there is no included quota, and every dollar of usage comes straight out of the wallet — pay-as-you-go, in the ordinary sense. ## The plans Each plan buys more usage than it costs, which is where the saving comes from: | Plan | Price | Included quota | Concurrency limit | Saving past quota | | ------- | -------- | -------------- | ----------------- | ----------------- | | Starter | \$19/mo | \$30 | 20 boxes | \$11/mo | | Pro | \$149/mo | \$250 | 100 boxes | \$101/mo | | Max | \$499/mo | \$900 | 1000 boxes | \$401/mo | The last column is the quota minus the price. Once your usage passes a plan's quota, that is exactly what the plan saves you against paying full price from the wallet, every month. **Enterprise** is negotiated rather than self-serve: custom limits and compliance review, arranged through [sales@boxlite.ai](mailto:sales@boxlite.ai). A negotiated plan carries no public price, and an unlimited quota or concurrency shows as unlimited rather than as a number. ## Which one costs less Look up what the console reports as spent this month, and three thresholds decide it: | When your monthly usage passes | Move to | Because | | ------------------------------ | ------- | -------------------------------------------------- | | **\$20** | Starter | Starter's $19 buys $30 of usage | | **\$161** | Pro | Pro's flat $149 beats Starter's $150 at this point | | **\$601** | Max | Max's flat $499 beats Pro's $500 at this point | The first threshold is a plan's own price: past $20 of usage, Starter's flat $19 beats paying full price from the wallet. The other two are crossovers against the **previous plan's total cost** at that usage level, not against their own price — Starter's $19 plus overage reaches Pro's flat $149 at $160, and Pro's reaches Max's at $600. Below a plan's own price you are buying quota you will not use. These thresholds assume a typical month. If your usage swings — a heavy month followed by a quiet one — the plan price is charged either way, so size against your *steady* level rather than your peak. ## Concurrency is a separate decision Concurrency caps how many boxes run **at the same time** — not how many you create over a month, and not how much work each one does. It is independent of quota: you can hit the limit with quota to spare, and exhaust quota while running a single box. If you are building an agent fleet, size against your fan-out. An orchestrator that runs 40 parallel agents, one box each, needs a plan whose limit clears 40 — Starter's 20 will stall it halfway through the batch. So concurrency alone can push you onto a larger plan well before the money says to move. A fleet of 40 short-lived Small boxes might spend \$60 a month — Starter territory on cost — while needing Pro's 100-box limit to run at all. ## Changing plans The direction of the change decides when it lands and what you are charged: | Change | When it applies | What you are charged now | | ---------------------------- | ------------------------------------------------------ | --------------------------------------- | | **Upgrade** | Immediately, and the new quota is available right away | The prorated difference, today | | **Downgrade** | At the next cycle roll | Nothing | | **Cancel** | At the end of the cycle you have paid for | Nothing | | **Subscribe** (from no plan) | As soon as payment is confirmed | The plan price, through Stripe checkout | Two details worth knowing before you act: * **A downgrade does not cost you this cycle's quota.** The quota you already paid for stays available until the cycle rolls, along with the current plan's concurrency limit. * **A queued change can be called off.** While a downgrade or cancellation is scheduled, the console offers to keep your current plan instead, which discards the queued change. ## Troubleshooting | Situation | Why it happens | What to do | | ----------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------- | | New boxes are refused while your existing boxes keep running fine | You are at your plan's concurrency limit — the cap is on boxes running simultaneously, not on boxes created | Stop or delete a box to free a slot, or move to a plan with a higher limit | | Cost is showing as wallet-funded rather than quota-covered | This cycle's included quota is consumed, so usage now draws on the prepaid balance | Nothing is broken. Keep the wallet funded, or move to a plan whose quota matches your steady-state usage | | Your plan shows as having no subscription | The account carries no plan, so there is no included quota and no plan concurrency limit | Pick a plan, or keep running on wallet balance alone if your usage is below \$20/mo | | A plan change you scheduled has not happened | Downgrades and cancellations apply at the cycle roll, not immediately | Check the cycle end date. To act sooner, upgrade instead — upgrades apply immediately | | Switching away from your current plan is refused | Your plan is negotiated rather than self-serve, so it has no catalog price to switch against | Talk to [sales@boxlite.ai](mailto:sales@boxlite.ai) before changing | ## Next steps The hourly rates behind every dollar figure on this page.
