Which module are you using for stock tracking?

uc_stock

Should I have considered a different one?

No, uc_stock is good. I was asking because I've taken on responsibility for the Inventory module, which also tracks stock, so I wanted to see if this was something that I personally had to deal with.

uc_stock is core, and Shawn is the one to address the issue.

Right, the idea behind have the stock levels decrement at order submission is to reserve stock for orders so that anyone who places an order has been assured that there is stock for that order. Depending on your business logic, you may or may not want to do this. Anyway, it's become apparent now we must have a more configurable way to adjust stock levels. I think this is a candidate for workflow integration. This way store administrators can configure where to adjust stock levels (order submission, payment received, order completion, etc.).

Okay, that makes sense. For my purposes the current system works pretty well, so I didn't want to create a lot of work here. I just wanted to point out that I saw a single order result in stock levels decreasing 3 times. For anyone trying to track their inventory carefully, this means it could become out-of-synch. I'm just using it as a warning that inventory is getting low, not precise tracking so it is not a big deal for me.

Thanks,

To follow up here, the uc_stock module now uses a default workflow configuration to implement stock adjustment upon completion of an order. This can configuration can be turned off using the Workflow-NG UI.
