POS works in three ways: from the browser<\/strong>, from the Desktop Application<\/strong> for Windows, or from the mobile application<\/strong>. POS in the browser needs an internet connection to complete a sale, while the two applications let you sell online or offline<\/strong> and then send the invoices to your account. This guide explains what works and what stops when the internet is down in each method, where orders are saved, what happens to invoices when the connection returns, device limits, and error messages.<\/p>\n

    Note:<\/strong> The Desktop Application<\/strong> card in POS Settings<\/strong><\/a> isn\u2019t available in all accounts, and the POS Settings<\/strong><\/a> page itself requires the Edit General Settings<\/strong> permission. The mobile app page works only if the POS app is enabled.<\/p>\n<\/div>\n
