InvoicePlane is an open-source invoicing solution that offers customization and self-hosting, making it ideal for users with technical skills. In contrast, BeachCandy provides a more comprehensive suite of features with integrated payment processing but comes at a subscription cost and lacks the flexibility of open-source software.
