@Howard we have this quite a bit, and what we do is enable invoicing prior to fulfilment, then just invoice the customer when they pay and fulfil as we ship. Apparently from an accounting perspective, the GL impact is not exactly correct but compared to what we used to do (keep paper records) it's a huge improvement

Yeah that could work, however, the Inventory would still reside on the balance sheet

That could be why the accountant wasn't mad about the idea

This is preferred messy option number 1. You might add a wrinkle to "accrue" for the late inventory expense with a journal or custom transaction. Method number 2 is to mark your item "picked" using pick pack shipped, and then later come back and mark it packed/shipped. The GL impact will actually fall in the period that it was marked picked. However, this involves leaving the period open. Method 3 involves transferring the inventory to a non inventory holding location, (inventory is not available) so that the value comes off the balance sheet and the inventory isn't in your primary warehouse. This requires a lot of work, and can often result in bad COGS. Not my preferred Solution. Method 4 involves a bunch of custom transactions and I'd want you to pay me to figure it out. Haha.

@michoel We decided to "ship" the item fulfillment from one location, then add the inventory at zero cost on a seperate location dedicated to the customer via a vendor bill

Thanks for sharing. I don't think it would work for us for a couple of reasons
