Billing

Questions about paying.

Comment 1Why credits instead of a subscription?
Response

Manuscripts are infrequent. A paper usually goes through two or three drafts before it is accepted, so a pack of three matches one paper, and credits never expire between projects.

Comment 2What counts as one report?
Response

One manuscript file, up to 30 MB, reviewed in full with references checked. A revised draft of the same paper is a new report, compared against the previous one.

Comment 3How do refunds work?
Response

If a full report has fewer than three substantive issues, email us within 30 days and we refund that report. If a report fails to generate, the credit is returned automatically.

Comment 4Can my lab pay centrally?
Response

Lab billing with monthly invoices and private workspaces for each member is planned. Until then, the 5-report pack can be shared across a PI’s manuscripts.

Pre-submission review for life-science manuscripts. A self-check before you submit — not a substitute for peer review.
