Editorial & Review Policy

Last reviewed: September 6, 2026

1. Editorial purpose

Ecomly Profit publishes calculators, marketplace comparisons, guides and explanatory content to help ecommerce sellers understand fees, costs, margins and modeled profitability.

Our editorial goal is to make commercially useful information clear, reviewable and transparent rather than to maximize page volume or present uncertain assumptions as facts.

2. Scope of this policy

This policy applies to calculator logic, marketplace fee assumptions, comparison content, educational guides, methodology explanations, update notes and other informational material published on Ecomly Profit.

3. Source hierarchy

For marketplace-specific rules and fee-sensitive claims, we aim to prioritize authoritative sources in the following order:

• official marketplace fee schedules, seller documentation and help-center pages;
• official policy, pricing or product documentation from the relevant service provider;
• official announcements or change notices;
• reliable secondary sources used only for context or clarification.

When secondary sources conflict with current official documentation, the official source should take precedence.

4. Marketplace fee reviews

Fee-sensitive information is reviewed against current official marketplace documentation where available. Because rates can vary by country, category, seller plan, fulfillment method, transaction type or promotional program, we avoid presenting one rate as universally applicable unless the source clearly supports that conclusion.

Where a fee is tiered, threshold-based, fixed-plus-variable or otherwise conditional, the relevant explanation or calculator should preserve that structure rather than reduce it to a misleading single percentage.

5. Calculator logic review

Calculator formulas are reviewed independently from marketplace fee-data reviews. This separation helps distinguish a mathematical or implementation issue from an outdated fee assumption.

Review may include checking known input/output scenarios, break-even relationships, percentage calculations, fixed-fee interactions, edge cases, zero-value inputs and whether displayed labels match the calculation being performed.

6. Methodology consistency

Calculator logic and educational explanations should remain consistent with our published Methodology. When methodology changes materially, related calculators and guides should be reviewed for consistency.

7. Educational content standards

Guides are written to explain ecommerce economics, marketplace structures and practical decision-making. Useful educational content should add definitions, worked reasoning, examples, context or actionable interpretation rather than repeat generic statements.

We aim to distinguish facts from assumptions and to make uncertainty visible where a marketplace rule or business outcome depends on user-specific circumstances.

8. Dates and review signals

Where useful, fee-sensitive guides, methodology pages or other trust-critical content may include publication, update or review dates. These dates are intended to help readers understand when material was last checked, not to guarantee that a marketplace has made no changes since that date.

9. Country, category and seller-plan differences

Ecommerce marketplaces often apply different rules by region, product category, seller plan, fulfillment program or transaction type. We aim to state those boundaries when they materially affect the usefulness of the information.

Users should verify commercially important assumptions against the official terms that apply to their own account and market.

10. Corrections

If we identify a material error in a fee assumption, formula explanation, calculator result, guide or page, we aim to correct it promptly and update the relevant content or logic.

Where a correction materially changes the interpretation of a page or tool, the content may be re-reviewed before it is treated as current.

11. Updates and maintenance

Marketplace fees, policies and seller programs can change without notice. Ecomly Profit may update calculators, guides or assumptions when credible new information becomes available.

Not every change requires a site-wide revision. Updates should be targeted to the pages, calculators or assumptions actually affected.

12. AI-assisted content

AI-assisted tools may be used to help draft, structure, summarize, compare or review content. AI output is not treated as an authoritative source for marketplace fees, legal requirements or factual claims that should be verified against primary documentation.

Where AI assistance is used, the responsibility for final publication, source selection, calculator logic and factual review remains with Ecomly Profit.

13. Commercial independence

Advertising, sponsorship or affiliate relationships should not alter calculator outputs, methodology or editorial explanations of marketplace economics.

Where a commercial relationship could reasonably affect how a reader interprets a recommendation or link, we aim to disclose that relationship clearly.

14. Affiliate disclosures

If Ecomly Profit uses affiliate links in the future, those links should be disclosed where applicable. Affiliate compensation should not change the formula, fee logic or factual explanation presented to users.

15. Third-party names and trademarks

Marketplace names, logos and trademarks belong to their respective owners. References to Amazon, Shopify, Etsy, TikTok Shop, eBay and other services are for informational, comparison or identification purposes and do not imply endorsement or affiliation unless expressly stated.

16. User feedback and error reports

Users who believe a calculator, fee assumption or explanation is incorrect can contact us through our Contact page. Reports that include the affected page, the disputed assumption and an authoritative source are especially useful for review.

17. Editorial limitations

Even with review procedures, Ecomly Profit cannot guarantee that every marketplace rule, fee schedule, external link or calculator assumption is always current or complete. Marketplace documentation can change, differ by account, or be implemented differently across regions and programs.

For material business decisions, users should verify relevant information directly with the applicable provider.

18. Related policies

This Editorial & Review Policy should be read together with our Methodology, Disclaimer, Terms of Use and Privacy Policy.
