You will not receive payment for late delivery of your books, unless you have a written guarantee of a specific date spelling out the conditions and/or consequences if that date is not met. Book printers have a general idea how long it takes to print a book in their plant. The actual time it takes depends more often on you. There are many questions to consider, including:
- How well is your self published book prepared?
- How long will you hold the book proofs?
- How many changes will you make?
To be on the safe side don't plan on having your self publishing books in hand until you actually receive them. Don't schedule a book signing or autograph party until you are absolutely sure you will have books in hand—you'll avoid a lot of worry and aggravation that way.
