I'll share some information on how to avoid duplicating books when sending receipts to your customer.
Normally, if you've created a one-time Sales Receipt for a cash-paying customer, it doesn't duplicate your books unless you created a new one and send it.
If you wish to resend a sales receipt to your customer without creating a new one, you can go to the register and process it there. I'll show you how to do it below:
- Go to Accounting and choose Chart of Accounts.
- Choose the bank that has the transaction and click View register.
- From the Bank Register, locate the transaction and click Edit.
- Once the transaction is open, review the information and click Save and send.
