Upgrade and billing
Updated 2026-11-13
This page shows how to move to a larger plan, what changes when you do, and how invoices and cancelling are handled.
Upgrade to Pro
- Open the service list.
- Click the round icon with your initial at the top right.
- Click the first entry of the menu. It shows your plan and Upgrade.
- The window Upgrade Your Plan opens. It lists Basic, Pro and Custom, and marks your plan as CURRENT PLAN.
- Click Pro. The payment page opens in a new browser tab, with the email address of your account filled in.
- Complete the payment. Keep the email address of your account on the payment page, so that the plan is assigned to the right account.
- Go back to SpreadAPI and reload the page. The account menu now shows Pro.
You also reach Upgrade Your Plan from the Upgrade button in the messages the app shows when you reach a limit, for example when you publish a second service on Basic or import a file that is too large.
What changes at once
As soon as the payment is complete, the Pro limits apply to your account:
- You can publish any number of services. See Published services limit.
- All workbooks of the account together may use 10 MB. See File size limits.
- The account has 10,000 calls a month. If calls were refused because the month's calls were used up, they work again shortly after the upgrade. See Call limits.
Your services, addresses, tokens and settings stay as they are. Nothing has to be published again.
The Custom plan
Custom is agreed individually: call volume, workbook size, a contract, support, and the on-premises runtime.
- Open Upgrade Your Plan as described above.
- Click Custom. Your email program opens with a message to support@airrange.io.
- Describe what you need: calls per month, the size of your workbooks, and whether you want to run services on your own infrastructure.
See On-premises runtime.
Invoices, payment details and cancelling
The app has no billing page. What the app does and what support does:
| Task | Where |
|---|---|
| See your current plan | Account menu in the app |
| Start the Pro plan | Upgrade Your Plan in the app, then the payment page |
| Ask for the Custom plan | Custom in Upgrade Your Plan, or support@airrange.io |
| Get an invoice or a copy of one | Write to support@spreadapi.io |
| Change payment details or the billing address | Write to support@spreadapi.io |
| Cancel Pro or go back to Basic | Write to support@spreadapi.io |
Pro is billed per month and can be cancelled at any time. Write from the email address of your account, so support can find it.
What happens when Pro ends
When the subscription ends, the account goes back to Basic. What you already have stays:
- Every published service stays online and can still be republished.
- A workbook larger than the Basic limit can still be saved as long as it does not grow.
- The account has 1,000 calls a month again. If more than that were already used in the current month, calls are refused until the 1st of the next month (UTC).
New actions are measured against Basic: a further service can be published only when no other one is online, and new or growing workbooks must fit into 250 KB.
If the plan does not show after paying
- Reload the app and open the account menu again.
- Check which email address you used on the payment page. The plan is assigned to the SpreadAPI account with that address.
- If you paid with a different address, or the plan still shows Basic, write to support@spreadapi.io with the address of your account and the address you paid with.
For developers and agents
- An agent cannot upgrade a plan or pay; this is done by the account owner in the app. When a limit of the plan stops you (
publish_limit,workbook_too_large,call_limit_reached), tell the user and name the limit. - After an upgrade,
what_can_you_doreturns the new limits underaccount. - Service IDs, addresses and tokens do not change with the plan.
FAQ
How do I upgrade to Pro?
Open the account menu at the top right of the service list, click the entry with your plan and Upgrade, and choose Pro in Upgrade Your Plan. Complete the payment on the page that opens, then reload the app.
How much does Pro cost?
€99 per month. It includes unlimited published services, 10 MB for all workbooks together and 10,000 calls a month.
When does the upgrade take effect?
As soon as the payment is complete. Reload the app to see Pro in the account menu; refused calls work again shortly afterwards.
I paid but my account still shows Basic. What now?
Reload the app first. The plan is assigned to the account whose email address was used on the payment page; if you paid with another address, write to support@spreadapi.io with both addresses.
How do I get an invoice?
Write to support@spreadapi.io from the email address of your account and say which month you need. The app itself has no billing page.
How do I cancel Pro?
Write to support@spreadapi.io from the email address of your account. Pro can be cancelled at any time, and the account then goes back to Basic.
What happens to my services when I cancel?
They stay. Published services stay online and can be republished, and existing workbooks can be saved as long as they do not grow; the calls per month go back to 1,000.
Can I go back from Pro to Basic in the app?
No. In Upgrade Your Plan lower plans are greyed out; write to support@spreadapi.io to end the Pro plan.
How do I get the Custom plan?
Click Custom in Upgrade Your Plan or write to support@airrange.io. Say how many calls a month you expect, how large your workbooks are, and whether you need the on-premises runtime.
Do I have to publish my services again after upgrading?
No. Services, addresses, tokens and settings stay unchanged; only the limits of the account change.
As an agent, can I upgrade the plan for my user?
No. Only the account owner can upgrade, in the app. Tell the user which limit was reached and that Pro or Custom raises it.
