When you make changes to your Air subscription mid-cycle—like changing plans, updating your billing cadence where that option is available, or working with Air on a contract or add-on change—you may see prorated charges in different places depending on the type of change. For eligible self-serve plan upgrades, the prorated amount due is collected during checkout. Other billing adjustments, including some support-assisted changes, may still appear on an invoice.
For eligible self-serve upgrades, the amount shown during checkout is a preview invoice for the immediate plan change. It includes the prorated amount due for the change and the new plan cost. Your ongoing recurring renewal amount appears later in Current Plan and on future invoices.
For step-by-step upgrade instructions, see Upgrading your workspace to a paid subscription.
Prorated billing applies when eligible subscription changes are made during an active billing cycle. These changes usually include plan upgrades or downgrades, billing cadence changes when self-serve options are available, and certain contract or add-on adjustments completed with Air.
Prorated billing means you're only charged for the portion of your billing cycle that reflects recent changes. These changes can include:
Upgrading or downgrading your plan
Changing your billing cadence when that option is available in workspace settings
Qualifying contract, add-on, or support-assisted billing changes
You'll only be charged for the time the plan or billing change was active, not a full billing cycle.
🧾 Only pay for the time you use 🧾
Monthly and annual subscriptions are billed in advance, and billing adjustments appear differently depending on the type of change. For eligible self-serve upgrades, checkout shows the amount due today and collects that charge as part of checkout. Other billing adjustments, including some support-assisted changes, may still appear as prorated line items on an invoice depending on the change.
Monthly plan credits refresh on your billing cycle and do not roll over, but that reset is separate from any prorated invoice adjustment.
When charges appear
Some subscription changes take effect immediately and are reflected through proration, such as eligible plan changes or billing updates made during a billing cycle.
After checkout, final invoice completion can lag briefly while tax calculation finishes, so charge visibility may not appear fully instantaneous.
Billing cadence changes, like moving from monthly billing to annual billing, depend on the options available in your workspace settings. Only options shown in workspace settings are self-serve. Enterprise storage changes, contract changes, and other options not shown in settings are typically coordinated with Air directly, even if the resulting billing adjustment later appears on an invoice. If you do not see the plan or billing option you need, contact Air for help instead of expecting a self-serve change.
📦 Storage and credit usage
Credits reflect ongoing usage based on what is stored in your workspace, not a one-time upload limit.
On Air's credit-based plans, storage is not documented as a separate fixed included TB amount. Instead, storage should be understood through ongoing credit consumption, and storage and AI enrichment draw from your workspace’s monthly credit balance continuously.
Storage uses 1 credit per GB per month.
AI enrichment uses 5 additional credits per GB per month for enriched assets.
Deleting assets mid-cycle returns credits because storage and enrichment are recalculated continuously.
You can view your credit balance and usage breakdown from the credit meter in the navigation bar. The meter shows how credits are being used for storage, enrichment, and AI generation, along with the next refresh date.
To avoid unexpected charges or usage limits, monitor your workspace credit usage regularly and remove unneeded files when appropriate.
For eligible self-serve upgrades, checkout shows the amount due today for the plan change. You may still see the following line items on invoices for other billing adjustments or on later invoice records:
Your plan – Your monthly or annual subscription charge for the current plan tier
Remaining Time – A prorated fee for time on the updated plan, add-on, or billing arrangement
Unused Time – A credit for the unused portion of your previous plan or billing arrangement
Once prorated adjustments are complete, your ongoing recurring rate is reflected by the standard plan charge on later renewal invoices or in Current Plan when self-serve pricing is shown.
📌 Quick Refund Policy Reminder
Air does not offer refunds or prorated refunds for subscriptions paid in advance.
🧠 Example invoice with prorated charges
This example shows a self-serve plan change. Not all subscription or billing changes follow this exact path.
Let’s say your billing date is the 8th of each month:
On the 28th of this month, you move from one paid plan to a higher paid plan.
If the upgrade is eligible for self-serve checkout, checkout shows a preview invoice with the prorated amount due for the change and collects that amount during checkout.
Your renewal date stays the same, and later invoices or Current Plan show the ongoing recurring charge for the updated plan.
Depending on the type of change, invoice records can still include prorated line items such as Remaining Time and Unused Time.
This means the amount due today during checkout and the recurring renewal amount shown later may be different, even though both relate to the same plan change.
Contact Air if your invoice line items are unclear, if the plan or billing change you need does not appear in workspace settings, or if you need help understanding which subscription changes are self-serve versus support-assisted. Message us or email help@air.inc.
