All articles published in IJPMBS (ISSN 2278-5221) are published in full open access. In order to provide free access to readers, and to cover the costs of peer review, copyediting, typesetting, long-term archiving, and journal management, the author's company or institution will be requested to pay a flat article processing charge of USD 300 for an accepted manuscript regardless of the length of the paper. The article processing charge is mandatory, and there are no charges for rejected articles. Article Processing Charges are required after a manuscript has been accepted for publication. The journal will not issue refunds of any kind after the acceptance of the manuscript. For reviewers, we will provide a discount voucher for each qualified review, and the voucher is effective within one year. Please note that the voucher is only applied for submissions in this journal, and the authors may use one or several vouchers for one submission.
