split billing issue: double deduction of the inventory and double invoice

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like the issue of double deduction of inventory and double invoicing could be due to multiple fulfillments and invoices being created from the same sales order. This could happen if you have a blanket sales order that you ship against every week. To verify if you have double charged the customer, you can perform a Transaction Saved Search. You can count the Billing Transaction: Document Number and find those with values greater than 1 (if it's usually 1 SO=1 Invoice). You can further refine it by adding criteria for quantity, amount, customer, date etc just to further filter. If you want to create two separate invoices for a single sales order, you could create a billing schedule, or bill the sales order twice, entering a quantity of 0.5 on each invoice line. If you have Advanced Revenue Management enabled and you're facing issues with billable costs posting to Deferred Revenue account first, you might need to create two different transactions, one with ratable rev rec and one with direct. If you want to create a single invoice for a customer with both billable time and billable expenses, you might need to create a custom scripting solution to produce a merged “invoice” from the actual multiple invoices transactions. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
