Facturaz is an all-in-one platform built specifically for autónomos in Spain who want to manage invoicing, taxes and projects independently in a modern, automated way. It integrates Verifactu compliance, project management, time tracking and tax model generation, all within a clean and easy-to-use dashboard. The goal is full automation and clarity without needing an external gestor.

Declarando, in contrast, positions itself as an online tax advisory service that combines software with human accountants. Its main strength lies in providing personalized fiscal guidance, optimizing deductions, and ensuring tax compliance with expert review.

However, it is less focused on daily operations such as invoicing, project management or time tracking and its interface is more geared toward collaborating with advisors than self-managing everything.
