What is the best strategy to have 2 different invoice numbering sequences within the same subsidiary? We need to separate invoices belonging to a specific category

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** To have two different invoice numbering sequences within the same subsidiary, you can use the feature of NetSuite that allows you to add subsidiary-based prefixes to invoice numbering. This can be done by following these steps: 1. Navigate to Setup > Setup Tasks > Auto-Generated Numbers. 2. On the Document Numbers subtab, check the Use Subsidiary box. 3. Then go to the subsidiary and set up the prefix. This way, you can differentiate the invoices based on the prefix of the invoice number. For example, you can start the invoice numbers for one category with a specific prefix and the other category with a different prefix. However, please note that this method might not work if your subsidiaries have different fiscal calendars. The auto-advance numbering creates a sequence by fiscal year, but the year comes from the transaction, which can cause duplication. For internal invoicing within the same subsidiary, there isn't an out-of-the-box solution in NetSuite. However, you can try creating entities with “representing department” and “department” fields and report on the outcome. Another way to do it is to create allocation schedules.
