Frenet

As reviews are overwhelmingly positive, with many users praising the app’s ease of integration with Shopify, practical logistics features, competitive shipping rates, and the convenience of generating labels and offering multiple freight options to customers. Support is also frequently highlighted as a strong point, with many merchants describing the team as fast, attentive, humanized, and helpful when issues arise. Several reviewers mention that the app has become an important part of their daily operations and that it improves logistics efficiency and customer experience. The main criticisms focus on billing and operational friction. Some users report unexpected or excessive fees, especially insurance and intermediary charges, and feel these costs are not clearly communicated. Others mention bugs, slow performance, unstable behavior, and integration issues such as incorrect data imports, difficulty correcting information permanently, and the need to fill in fields like CPF or address details manually. A smaller but important set of reviews also complains about weak onboarding, limited customization, label printing problems, and poor support or refund handling in specific cases.
