Is there any modules that help the coordination of businesses that receive in product from customers, process them, and then after processing it sends the same product back out to the customer?

Is this for Warranty purposes or more like a Purchase, work order, Sell back situation? Other Names might be a good functionality if the later. A lot of this depends on the GL impact you're expecting to see.

NetSuite has this module https://www.netsuite.com/portal/products/erp/supply-chain-management/support.shtml

Thanks for the feedback! Not warranty because the company didn't make the product they are just doing a step as part of the overall manufacturing process for the manufacturer

So you are like an outsourced MFG for a different company? So customer buys product from Company A. They need a repair so they send it to you. You repair and send back to customer. You bill Company A for your work Is that right?

Its not a "repair" per say since it's like an added service, like say a special paint job. but more or less you have the process down right.

I see maybe a $0 PO to recieve product then a WO for value add services. Then a SO to ship it?

Yes essentially. But seems like there should be a special transaction for this as it's not really a PO

I can’t think of one. You could make a custom transaction that functions just like a PO but is called something different

We would be using POs to purchase goods like how it's traditionally used. It's like a RMA but it's also not an RMA

Or just post an inv adjustment for them
