Payment of the APC fee (directly to the publisher) by the author or a funding body is not required until AFTER the manuscript has gone through the full double-anonymized peer review process and the Editor(s)-in-Chief at his/her/their full discretion has/have decided to accept the manuscript based on the results of the double-anonymized peer review process. 
What Does IGI Global Scientific Publishing's Open Access APC Cover?
In the traditional subscription-based model, the cost to the publisher to produce each article is covered by the revenue generated by journal subscriptions. Under OA, all the articles are published under a Creative Commons (CC BY) license; therefore, the authors or funding body will pay a one-time article processing charge (APC) to offset the costs of all of the activities associated with the publication of the article manuscript.
