I am having difficulty deducting cis of my invoice’s while using the app , it doesn’t even come up in the tax bracket at total figure

Let me help you with your concern, @craigtaylor8-me-.

QuickBooks Online (QBO) is cloud-based accounting software that can handle CIS transactions. The QBO mobile app and the browser version have different interfaces. What I can recommend is to use your preferred browser while processing your CIS.

Open private windows such as:

·        Ctrl + Shift + N (Google Chrome browser)
·        Ctrl + Shift + P (Mozilla Firefox & Microsoft Edge browser)
·        Command + Shift + N (Safari browse)
 
If you have any suggestions that will improve the QuickBooks app you can drop some comments here at this link.
