Upgrading or downgrading your plan
You can change your Costello plan at any time from the Billing section of your workspace settings. Changes take effect immediately.
Upgrading
- Go to Settings → Billing in your Costello workspace.
- Click Upgrade on the plan you want.
- Enter your payment details if you haven't already.
- Confirm. The new plan activates instantly.
When you upgrade mid-cycle, you're charged a prorated amount for the remainder of the current billing period. For example, if you upgrade halfway through a month, you pay half a month's difference between your old and new plan price.
Your message allowance resets at the start of your next billing cycle (not immediately on upgrade), so upgrading in the middle of a month won't restore messages you've already used this cycle.
Downgrading
- Go to Settings → Billing.
- Click Change plan and select the lower plan.
- Confirm the downgrade.
Downgrades take effect at the end of your current billing period — you keep full access to your current plan until then. You won't be charged for the next cycle at the higher rate.
Things to check before downgrading:
- Channels: Growth supports 2 channels; Free supports 1. If you're on Growth with Instagram and Messenger connected, downgrading to Free will disconnect one channel. Costello will prompt you to choose which one to keep.
- WhatsApp: Unlimited only. Downgrading from Unlimited disconnects WhatsApp automatically at the end of the period.
- Message cap: The lower plan's cap applies from your next billing cycle. If you've already used more messages this cycle than the new plan allows, the current cycle isn't affected — the cap kicks in next month.
Cancelling
Cancellation is the same flow as downgrading — go to Settings → Billing and click Cancel plan. Your paid features remain active until the end of the billing period you've already paid for; after that your workspace drops to Free.
Your data (conversations, knowledge base, settings) is retained for 90 days after cancellation in case you return.
