Amazon has apologized after a glitch in its AWS billing system generated invoices as high as $1.5 trillion for some users. The company attributed the error to a problem with unit pricing calculations in its estimated billing computation subsystem.

The billing error affected multiple AWS customers, with one UK user reporting an invoice of £5.8 billion ($7.3 billion) despite typically paying under £1 monthly. The customer said he "almost had a heart attack" upon seeing the erroneous charge. Amazon confirmed the issue stemmed from faulty unit pricing within its billing system's subsystem for estimated charges. The company has issued an apology to affected users. The incident highlights the risks of automated billing systems handling complex calculations at scale. AWS, Amazon's cloud computing division, processes billions in charges monthly across hundreds of thousands of customers worldwide. It remains unclear how many users were impacted or what steps Amazon is taking to prevent similar errors. The company has not yet disclosed details about refund processes or compensation for affected customers. AWS is a critical service for businesses worldwide, making billing accuracy essential to customer trust.
