Invoice Maker by Billdu is primarily an invoicing and expense tracking application. It offers features like creating invoices, estimates, and purchase orders, tracking expenses, and accepting card payments. While it has some overlap with payment processing and reporting, it lacks the comprehensive developer-first payments infrastructure, advanced fraud detection, and specialized financial services that Stripe provides. The API mentioned is for integration with their invoicing system, not a full payment platform API.
