Article processing charges (APCs) support peer review coordination, editorial management, production, DOI registration, and long term archiving. APCs are applied after acceptance and do not influence editorial decisions.

IPJ is committed to transparency and affordability for authors in physiology research communities.

• Editorial assessment and peer review management
• Copyediting, layout, and publication production
• DOI registration and metadata validation
• Long term archiving and platform maintenance
• Open access hosting and global dissemination

Authors from World Bank classified low income and lower middle income countries may be eligible for partial APC waivers. Requests are evaluated on a case by case basis and must be submitted before acceptance.

Membership options offer discounted APCs for eligible authors and institutions. Contact the editorial office for guidance.

To avoid delays, payments should be completed within 48 hours of invoice receipt. Publication proceeds after payment confirmation.

APCs cover the full publishing workflow, from editorial assessment and peer review coordination to production, DOI registration, and long term archiving. These services ensure rapid dissemination and reliable indexing for physiology research.

• Editorial screening and reviewer coordination
• Copyediting, typesetting, and proof production
• DOI registration and metadata validation
• Hosting, archiving, and platform maintenance
• Indexing support and compliance checks

IPJ supports institutional billing and membership discounts for eligible authors. To streamline invoicing, provide institutional contacts at acceptance and confirm preferred billing details in advance.

• Institutional invoices available on request
• Membership discounts for participating institutions
• Partial waivers for eligible low income regions
• Payment confirmation required to initiate production

Teams should plan APCs early in the research lifecycle to avoid publication delays. IPJ supports institutional billing and transparent documentation to streamline approval workflows.

• Confirm APC coverage with funders or institutions.
• Identify the responsible billing contact at acceptance.
• Prepare purchase order or grant documentation if needed.
• Check eligibility for membership discounts or waivers.
• Ensure correspondence emails are up to date.

Partial APC waivers are considered for eligible authors from low income and lower middle income countries. Requests should be submitted before acceptance with supporting documentation.

• Submit waiver requests during initial submission.
• Provide evidence of eligibility or institutional status.
• Confirm whether co-authors have alternative funding.
• Membership discounts apply to participating institutions.

Invoices are issued after acceptance and should be settled promptly to avoid delays. Production begins after payment confirmation, and DOI registration follows proof approval.

• Provide invoice details and tax information where required.
• Confirm preferred currency and payment method.
• Retain receipts for funder reporting compliance.
• Contact the editorial office for billing questions.

Many institutions require documentation for APC payments. Preparing materials early helps avoid delays during production and publication.

• Maintain grant numbers and funding acknowledgments.
• Prepare internal approval forms or purchase orders.
• Confirm billing contacts and preferred invoice formats.
• Document waiver requests and eligibility evidence.
• Retain payment receipts for compliance reporting.
• Verify tax or VAT requirements before payment.

Some funders require proof of open access licensing and publication timelines. IPJ provides documentation after acceptance and payment confirmation.

• Request proof of CC BY 4.0 licensing if needed.
• Confirm DOI assignment after production completion.
• Include publication details in funder reports.
• Coordinate with institutional libraries for OA tracking.

IPJ is committed to rigorous, transparent publishing in physiology research. We emphasize reproducible methods, clear reporting of experimental protocols, and ethical compliance across all article types.

The editorial office supports authors, editors, and reviewers with clear guidance and responsive communication. For questions about scope or workflow, contact [email protected].

We encourage continuous improvement in reporting practices and share updates that help the community maintain high standards in human and comparative physiology.
