To ensure a clear understanding of your Google Document AI billing, I recommend reaching out to Cloud Billing Support directly. They can provide specific details regarding your use case and clarify any discrepancies between your invoice and the published pricing information.
While the published pricing guidelines offer a general framework, it’s possible that your bill reflects additional charges for features like page processing or data extraction. It’s also possible that factors such as document complexity, data extraction volume, or potential billing system variations could influence the final cost.
Google Cloud offers free Cloud Billing Support to all customers. Should you require assistance with your billing account, I encourage you to visit their Cloud Billing Support page for contact options.
