Profits from Print on Demand Services publishing are on a per-sale basis, and royalties vary depending on the method by which the item is sold. Greatest profits are usually generated from sales direct from a print-on-demand service's website or by the author buying copies from the service at a discount, as the publisher, and then selling them personally. Lesser royalties come from traditional bookshops and online retailers both of which buy at high discount, although some Print on Demand Services companies allow the publisher or author to set their own discount level. Unless the publisher or author has fixed their discount rate, the greater the volume sold the less the royalty becomes, as the retailer is able to buy at greater discount.

Because the per-unit cost is typically greater with Print on Demand Services than with a print job of thousands of copies, it is common for Print on Demand Services books to be more expensive than similar books made by conventional print jobs, especially if a book is produced exclusively with Print on Demand Services instead of using Print on Demand Services as a supplemental technology between print jobs.

Book stores order books through a wholesaler or distributor, usually at high discount of as much as 70 percent. Wholesalers obtain their books in two ways: either as a special order such that the book is ordered direct from a publisher when a book store requests a copy, or as a stocked title which they keep in their own warehouse as part of their inventory. Stocked titles are usually also available via sale or return, meaning that the book store can return unsold stock for full credit as much as one year after the initial sale.

Print on Demand Services books are rarely if ever available on such terms because for the publishing provider it is considered too much of a risk. However, wholesalers monitor what titles they are selling, and if authors promote their work successfully and achieve a reasonable number of orders from book stores or online retailers (who use the same wholesalers as the stores), then there is a reasonable chance of their work becoming available on such terms.

Although returnability lessens the risk for book stores, only a certain proportion of such stock can be returned. Non-returnability can make bookstores less enthusiastic about Print on Demand Services books.

Many print-on-demand titles are debut works; many bookstores are reluctant to risk an author's first, untested work without the endorsement of a commercial publisher.
