What flexible payment options do you offer?
We offer flexible payment options to suit the author, so can more-or-less offer any option that works for the individual.
For example, some authors prefer to pay a set amount each month over a long period of time. Others would prefer to pay fewer payments (and slightly higher) but with a few months in between where payment is not due, so it really depends on what works for the author.
One option for your Publishing Advisor to provide you with a payment option that works for you would be to let them know if you have a maximum payment amount that you would not want to exceed per payment. They would then be able to let you know how many payments would be required and when publication date would, therefore, be scheduled.
