how to group multiple invoices in one email to customer?

AI generated answer (using internal Slack threads):

In NetSuite, you can group multiple invoices into one email to a customer by using the Consolidated Invoicing or Invoice Grouping feature. Here are the steps to do it: 1. Create sales orders against the customer and mark them for grouping. This will create a single invoice "group" against them. 2. You can also use a Suitelet where users can select the customer. Based on the customer selected, all the invoices should come in the sublist of the Suitelet. They can then click one checkbox against each invoice they want to group. 3. Click on a button which calls another Suitelet that generates the PDF. You can use advanced PDF or write HTML code in Suitelet itself to create the PDF format. The appearance of the invoice will depend upon your needs. 4. You can then use a Map/Reduce Script to get the invoices to send. Use

render.transaction()

to get the printed PDF and then send the email using SuiteScript. You can put the emails on the invoice or customer record. Please note that the Invoice Grouping feature is not intuitive and you should test it thoroughly before implementing it. Also, keep in mind that the limit is 10 recipients per email. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
