It seems that a project is assigned to only one company and, as a result, you cannot enter an invoice in a different entity but with the same project. Example: I have a project called HR General Expenses, and I would like to be able to enter invoices from my 3 entities. It seems that over time, and with expense reports, this doesn’t cause an issue, but with invoices, it does."

Based on the conversations, it seems that NetSuite does allow for the creation of invoices for multiple projects under the same customer and subsidiary, provided they use the same currency. This can be achieved by enabling the 'Consolidate Projects on Sales Transactions' accounting preference. However, it's important to test this extensively as it may affect other functionalities and any customizations in your NetSuite account. For the case where you need to invoice a customer that is different than the one listed on the project, it appears that NetSuite does not allow you to select a customer different than the one listed on the project. A workaround that has been used is adding a new billing address on the single customer record, but this may not be ideal as it can affect your Accounts Receivable. For the scenario where you need to raise/create an invoice for a group of projects under one customer and send a single copy of the invoice to the client, you could use group invoicing. This would involve creating sales orders with the billable time (one for each project), invoicing those sales orders, and then grouping them together. This process might be a bit tedious but it should achieve the desired result. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
