Offline mode is currently only available in the FooSales tablet apps
The FooSales offline mode makes it possible to process orders via the FooSales apps without having to connect to the internet. Offline mode can only be utilized after you’ve logged in and completed an initial download of all your relevant store data.
All new orders, cancelled orders, refunds and product changes are stored on your device and can be synced with your WooCommerce database when you’re back online.
To enable offline mode, go to Settings and enable the Offline Mode setting. When doing so, a bar will display at the bottom of the screen which reflects the time the app switched over to offline mode.
You can go back online at any time by disabling offline mode in the Settings screen or by tapping Go Online located at the bottom right of the footer bar. The app will then attempt to sync all the new orders and changes that were made while in offline mode with your WooCommerce store.
You can also clear or export any changes made while in offline mode. If you choose to clear your offline changes, the app will revert all products and orders that were modified while in offline mode back to the original values when the app was last online. If you disable offline mode after clearing your offline changes, there won’t be any data to sync with your store.
If you export your offline changes, a custom XML file is generated that you can send to an email address as an attachment in order to back-up all offline activity. You can then make use of the FooSales import tool which you will find under the ‘FooSales’ sidebar menu in your WordPress Admin Area to import this XML file containing all your offline activity. You will see a log of all the changes that were made to your WooCommerce database once the import has completed. Please note that all offline changes will only be imported once, so if the import times out and you re-import the same file, any changes that were previously imported successfully will be skipped.
