Price Per Letter: Charge Customers Based on Text Added (Shopify Plus Only)

We're excited to announce a new feature that many of you have been requesting Price Per Letter!

This powerful tool empowers you, the Shopify merchant, to set a custom charge based on the number of characters entered by your customers in a specific text field on the Product page. This offers greater flexibility in your product pricing, allowing you to accurately reflect the additional costs associated with processing longer text.

This exciting feature leverages the latest update from Shopify, the Cart Transform API. This eliminates the need to link the charge amount with an add-on variant.

⚠️ Important Note: Shopify Plus Only (For Now)

We understand this might be disappointing news for some merchants. This feature currently utilizes Shopify's latest update, the Cart Transform API, unfortunately, at this time, the Cart Transform API is only available for Shopify Plus plans. This means the "Price Per Letter" feature is currently limited to Shopify Plus users.

We sincerely apologize for any inconvenience this may cause. However, this limitation is imposed by Shopify itself. Rest assured, our team is actively monitoring the situation and will readily integrate this feature with all plans as soon as Shopify makes the Cart Transform API universally accessible.
