General Information on Article Processing Charges (APC) and Market Reports

• SPER publishes all its journals in full open access under a Creative Commons (CC BY) license. This allows the scientific community and the general public to gain unlimited, free and immediate access to scholarly articles. To cover the cost of publication, authors pay an article processing charge (APC) for manuscripts accepted after peer-review. There are no charges for rejected articles, no submission charges, and no surcharges based on the length of an article, figures or supplementary data. Editorial items (Editorials, Corrections, Additions, Retractions, Letters, Comments, etc.) are published free of charge.
• SPER will provide the final market report to the customer after receiving the full and final payment.

Terms of Payment

• The applicable price for the publication service regarding an accepted Article is based on the date of the original submission of the Article to SPER.
• Discounts on the service price apply for authors affiliated with institutions that have signed-up to SPER’s institutional open access program (IAOP) and may be granted to reviewers. Furthermore, SPER may grant discounts and waivers in exceptional cases, however, reserves the right to decline such discounts and waivers without specifying a reason.
• Payments to SPER are due within 5-10 days of sending the invoice to the Customer.
• Invoices are sent by e-mail to the payment contact person provided by the Customer soon after acceptance of an Article for publication.

Avoiding Surcharges from Extensive English Editing or Extensive Reformatting on Submitted Articles

• Submitted papers should be well formatted and use good English. Authors may use SPER's English editing service prior to publication or during author revisions. If you use an alternative service that provides a confirmation certificate, please send a copy to the Editorial Office. Authors from developing countries should consider registration with AuthorAid, a global research community that provides networking, mentoring, resources and training for researchers in developing countries.

Funding of APCs

• Many funding agencies and institutions explicitly allow the use of research grants for the payment of APCs for publishing in open access journals.

Discounts on APCs

• SPER provides discounts for authors under an Institutional Open Access Program (IOAP) and has established agreements with many institutions. If your institution does not yet participate, you may recommend the program to your librarian.
• Selected articles invited by the Editorial Office are published for free. Waivers may be granted at the Publisher's discretion and should be discussed with the editorial office when submitting the article. The editorial decision making is decoupled from the authors' ability to pay the Article Processing Charges, however authors should consider in advance whether they have sufficient funds to cover the full APC.
• SPER also offers discount vouchers to selected reviewers.

Accepted Currencies

• We accept payments in nearly all currency powered by CCAvenue payment gateway (Avenues India Pvt. Ltd.). Upon acceptance, the cutomer/corresponding/submitting author will receive an e-mail.
