I’m invoicing a company that deducts 20% so when it goes into my bank it can’t be matched how do I sort this out please?

Hi @leehyland1969-me,

QuickBooks Online (QBO) has a specific feature available that's called Resolve Difference, made for this situation. 

Follow these steps:

1. Go to the Transactions tab.
2. Select the online bank account in question. 
3. Under the For review tab, click the transaction in question. 
4. Tick the Find match radio button. 
5. On the list that appears, choose the correct invoice for the payment. 
6. Scroll down and tap the Resolve Difference option at the lower-right of the page. 
7. Enter an expense account under the Category column since the 20% deduction is an expense.
8. Fill in the amount, as well other details as you see fit. 
9. When done, hit Save.

Take a look at this article for additional information: Categorise and match online bank transactions in QuickBooks Online. 

You also have the option to match your bank transactions if you use the mobile app for QBO. See the steps in this article: Match your bank transactions in the QuickBooks Online app.
