If you want to reach more readers and make more money you should publish your books on both IngramSpark and KDP (formerly Createspace). Read on for reasons why.
Print on Demand
Books are printed when they are order
No need to have extensive inventory on hand
No need to fulfill the orders as they come in
Steps
1.Reader orders the book
IngramSpark and KDP fill the order
IngramSpark and KDP take their cut (production and distribution) and pay you the rest
Pretty much it works the same for both POD platforms
Benefits of each:
KDP
Free
Only makes money when someone buys your book
Automatically included in the Amazon Store
IngramSpark
Upload cost of $49 annual fee which is minimal
Master distribution network that includes brick and mortar stores and libraries
See them as competition
Terms are not good for them
Paperwork is insane
Print choices
Hardback option
New Personalization Service
Can distribute on Amazon
Amazon uses IS to fulfill some of their orders
Requires own ISBN # use on both IS and KDP
*Amazon will provide out of stock notice on IS only print books.
Best of both worlds!
