I am looking for another way to say "back order" (see definition below). I think not many people understand what "back order" means and am looking for a more generally know word/phrase.
noun: back order; plural noun: back orders; noun: backorder; plural noun: backorders
- a retailer's order for a product which is temporarily out of stock with the supplier. "the phone I wanted was on back order"
verb: back order; 3rd person present: back orders; gerund or present participle: back ordering; past tense: back ordered; past participle: back ordered
- place an order for (a product) which is temporarily out of stock. "the taps can be back-ordered and take up to three months for delivery"
Edit: I am asking this question because native speakers are not understanding the meaning. Ideally there would be another word or phrase that had the same meaning that was more widely known. Failing that, a succinct description will have to suffice.
