We need to set up a POS system possibly Vend for our shop, When we receive stock, we have QB online and Vend set to sync, will the stock automatically go up onto the POS?

Hi there, @kerrieanne-harte.

I want to ensure that your POS concern gets addressed. That said, let me point you over to the best support that can handle this inquiry.

The data that will sync into your QuickBooks and POS will depend on the integration setup. This significantly reduces workload as it keeps you from entering the information twice. 

To help verify if the stocks will automatically go up into the POS, I recommend reaching out to your POS provider. They'll be able to check your settings and provide further details about this matter.

Know that you can always utilize this link, which talks about adding your stocks in the system for your reference: Learn how to add your stock products in QuickBooks Online Plus.

Please know that I'm just a post away should you need anything else. Wishing you a wonderful day ahead.

Did you try to integrate both apps? Afaik, it only supports QBO US version. Consider opening the trial account of QBO Plus UK version.
