Twilio has introduced customizable receipts in its account portal, allowing developers to simplify accounting and tax-filing tasks by adding personal information necessary for in-country tax deductions. The new feature enables the generation of a rollup of past payments in a simple list, eliminating the need for manual data export, editing, and review. The Twilio account portal now supports filtering and rolling up payments by month, as well as including company information such as name, address, and Tax ID on receipts. This update aims to simplify billing and tax workflows for pay-as-you-go customers, providing a more streamlined experience.
