Proper way to cancel invoice?

AI generated answer (using internal Slack threads):

To cancel an invoice in NetSuite, the recommended method is to create a Credit Memo. This is the best way to remove the invoice without negatively affecting your Accounts Receivable (A/R). Here are the steps to create a Credit Memo: 1. Navigate to the Customers menu, then select Create Credit Memos/Refunds. 2. In the Customer field, select the customer for whom you want to create a credit memo. 3. In the Date field, enter the date for the credit memo. 4. In the Invoice field, select the invoice that you want to credit. 5. Click on the Items tab, and then in the Items list, select the items that you want to credit. 6. In the Quantity field, enter the quantity that you want to credit for each item. 7. Click Save. If the invoice is associated with a revenue plan or arrangement and it is voided, you can cancel the revenue plans and arrangements by creating a Return Authorization. This will create its own negative revenue plan, and the two plans will cancel each other out. For vendor bills, you can create a Bill Credit to net it out after it's been approved. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
