Paybook is a company that provides a solution helping users transforming raw financial data into an organized format. Its product Sync, a RESTful API, retrieves user-authorized account and transactional data from banks and credit cards, the SAT (Mexico’s tax authority), and insurance, telecom, and utility providers and returns it to third-party solutions in an organized usable format. For countries that require e-invoices with verified digital signatures, it allows developers to offer their customers the ability to generate bills that comply with government regulations.
