Bulk changes to payments and receipts

I have made an error in inputing some payments on my accounts. They weren’t GST registered, but I put them as GST 15%. I want to change them, is there a way to do a bulk change? Or do I need to manually change each one?ave I’m not sure I have explained this clearly enough, I’m sorry, I’m not sure how else to say it.
Thank you.

I suggest reading the guides on find & recode for payments and receipts Find and recode receipts and Find and recode payments | Manager

The alternative is to use batch operations, which is more powerful but harder to use. For details see to guide section

Batch Operations: Use Batch Create and Batch Update functions | Use the Batch Delete function | Use the Batch View function

Thank you. I’m off to read now.
