Thanks for choosing QuickBooks Online (QBO) as your accounting partner, @Joss B. I'm here to help get rid of the error so you can add your transactions to the program seamlessly. 

You'll receive that error if the account assigned to the transaction you want to add is deleted or marked as inactive in QBO. To fix this, let's go to your Chart of accounts page and check the lists of inactivated accounts. I'll guide you on how:

1. In your QBO account, go to the Gear icon and select Chart of accounts.
2. From there, click the small Gear icon at the upper right part of the page.
3. Then, check the box for Include inactive option.
4. Scroll down and review all the inactivated accounts. Then, check if you can see the 2550 VAT Liability account (as stated in the error).
5. Select the Make active button to reactivate them.

Once done, refresh your QBO page and start adding and accepting transactions again. For reference, feel free to browse this article: Categorise and match online bank transactions in QuickBooks Online.

If the same thing happens, you can also perform some browser troubleshooting steps to resolve the error. To do so, you can access your QBO account via incognito mode. Below are the shortcut keys you can use:

• Google Chrome: press Ctrl + Shift + N
• Mozilla Firefox: press Ctrl + Shift + P
• Microsoft Edge: press Ctrl + Shift + P
• Safari: press Command + Shift +N

Then, add the transactions again. If this work, go back to your regular browser and clear the cache. If not, you can use another supported browser or device in accessing your QBO account.

I've also attached this helpful resource that you can use as a guide in balancing your accounts in QBO: Learn the reconcile workflow in QuickBooks.
