I have input a wrong sales receipt and need to delete it as it's affecting thevat to be paid how do I do this ?

Thanks for posting in the Community, @westgrangesolutions. 

Let's go to the Sales menu so you can delete the incorrect sales receipt. This also decreases your VAT amount to be paid. I'm here to guide you through the steps. 

1. Go to Sales from the left menu. 
2. Locate and open the sales receipt. 
3. Select More in the footer. 
4. Choose Delete. 
5. Click Yes to confirm. 

The screenshot below shows you the third and fourth steps. For detailed instructions, go through this article: Void or Delete Transactions. 

You can always go back to the Sales page to view the statuses of your sales transactions. From there, you can create and edit them. To learn more about this page, check out this article: View Sales Transactions.
