Use package pricing to charge per block of units or usage. Define a package size and bill only in whole packages. For example, if you charge $10 for every 1,000 API calls, the package size is 1,000 units.
How packages are counted?
Chargebee bills in whole packages. Within each tier, usage is rounded up to the next whole package.
Package Pricing Example (OpenAI – GPT-5):
Package size: 1M tokens. Price: $1.25 per package.
1,000,000 tokens = 1 package = $1.25
10 tokens = 1 package (minimum) = $1.25
1,500,000 tokens = 2 packages = $2.50
Note:
Package pricing can be set for metered items(plan or addon).
Currently, package pricing is available for tiered, volume based pricing models(plans and addons) only.
Configure package pricing for a tiered or volume-based plan or addon:
Select Allow advanced pricing configurations for this item.
Define Package Size for each tier.
Example: If a customer consumes 350 units, the total payable amount is $800.
Limitations
The package size does not sync with Chargebee's native integrations, such as Sales, Finance, and others. However, all other integration-related functions are supported.
