Hi there. Thanks for reaching out to us here. I can see the importance of being able to switch the language to French on your QB Self Employed app. As Fiat Lux - ASIA has mentioned above, the app is available in English. I'd recommend exploring options such as QuickBooks Online which gives you the flexibility to manage your work in French. Feel free to learn more here. Let me know if you have other questions, I'm here to help.
