How to add project billable charges to invoice by suitescript

AI generated answer (using internal Slack threads):

To add project billable charges to an invoice by SuiteScript, you need to follow these steps: 1. First, you need to ensure that the charges are set up correctly in the project record. They should be pulled onto the Sales Order (SO) as expected. If you are not using SOs, you cannot Bill Sales Orders, since there is nothing to bill. Instead, you should use Process Billing Operations. 2. If you are using a charge-based billing type with the feature 'Consolidate projects on sales transactions' enabled, you need to create a Sales Order and choose the Customer record. Just above line level, there is an option “refresh items from project”. Select the project and it will auto populate the charge items from the project to show on the Sales Order. Once you generate a charge on a project and set it to ready, a button will show of Next Bill on Sales Order. 3. For time-based charges, you need to Approve the time, then click the Generate Charge time button. Once the charge is generated you can then define it as ready so it shows for your next bill option on the sales order. 4. If the billable time is not showing on the Items tab, check if your item is marked as “can be fulfilled”. For an item to be used with charge-based billing that checkbox has to be blank. Please note that this process might vary depending on your specific NetSuite setup and configuration. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
