I am not aware of any manufacturer we (LHS) represent to our customers who require 'front money' for an advance order. More typically it is a retailer's policy in the conduct of their business.
That said, however, you should know that some distributors (in particular) accept preorders from dealers on the basis that their order is firm, not cancellable. This is typically for the big ticket ($$$) items, but items having a very short manufacturing run, very limited production, may also be subject to this distributor's policy. And the distributor's policy often traces back to the manufacturer's requirement.
The reason is quite simple....they don't want to be left 'holding the bag'. That's understandable.
I suspect your question revolves around your own access to money that the retailer required from you in order to place an advance order. You can probably see that, if the LHS made a policy-shackled commitment on your behalf, they don't want to end up buying something that will be difficult to peddle should you bail on your commitment. I would certainly require the management to inform you of their policy regarding such advance payment before making the commitment, placing the advance order. Often there is a $$ penalty for reneging...say 15-25%, which can do two things: Pay down the interest on the money tied up in a long-term 'shelf' item, and/or offset an atypical discount the retailer might have to make on the item in order to move it. In other words, the retailer is trying to protect themselves financially.
Bailing on a commitment is not a pleasant thing for anyone in the daisy chain. It's 'damaging' to the relationship(s) all along the line. Credibility goes south. Prices and caveats go north.
The downside of all this is, of course, the veiled threat that 'if you don't order it, you can't expect to get it'. That is, manufacturers are scheduling closer and closer to the commitments, distributors are stocking closer and closer to commitments, and retailers are reducing speculative stock volumes in order to tighten the belt.
So, if you want to retain a thumb-and-forefinger grip on preorder monies, talk with the retailer BEFORE laying out the cash. Understand the commitment. Even get it in writing, if you have any concerns.
We (LHS) do not as common practice ask for front money...too much paper work. If the unusual order merits a down payment, however, we typically only charge a minimal percentage....not refundable. If this economy doesn't start to match the optimistic spin, however, that could change.
FWIW, always...
