All of my Gigs™ have a 48 hour turnover time, and I rarely deliver an order too early; unless the buyer has given me 100% of what I need and the specific order was very straight forward. Most of the time, there is communication between the buyer and myself before the delivery. The only time I have “delivered” an order before the project was finished occurs when I needed more information from a buyer in a time zone 20 hours away or something; and even then, I make sure to be transparent and provide all the current work with that delivery.
Delivering “ghost” work, simply for the benefit of a fast turnover average is irresponsible on the buyer’s part. Not only is it confusing customer service, but then the order can be marked complete, rejected, and open for bad metrics and reviews. When a client and I can’t come to an agreed decision, or I can’t deliver on time, I find it’s best just to request a mutual cancellation. It’s not worth the time otherwise, and it’s less stressful for both parties.
The only logical reason I can think of for the “ghost delivery” is that the seller wants their (your) funds distributed quicker, in hopes that you’ll go along with it and wait for your actual delivery whenever they get around to it.
Not something that I’d do to any of my clients.
