What We Publish
Commerce Tally publishes free calculators and practical guides for online sellers. That includes profit margin, markup, selling price, break-even, shipping cost, dimensional weight, marketplace fee (Etsy, Amazon, eBay and other platforms), payment processing, discount, return cost, inventory turnover, and sales tax arithmetic, plus guides on how to use those numbers. This page explains the standards we try to use when creating and revising that content.
The goal is practical trust. We want visitors to understand what kind of site this is, how its content is reviewed, and what judgment still belongs to the seller, their accountant, their marketplace, and their own business decisions.
What We Prioritize
- correct fee and pricing math, with formulas and limits stated plainly
- clear distinction between markup and margin, and between cost, revenue, and profit
- shipping realism, including when dimensional weight can cost more than actual weight
- practical guidance tied to real seller decisions, not just page labels
- honest framing of estimates, because fees and rates vary by platform, category, and account
- internal links that help readers move between related tools and guides
How Calculator Pages Are Reviewed
Calculator pages are reviewed for clarity, input guidance, result interpretation, and related links. We aim to make each tool explain what it measures, what assumptions it uses, and how to use the number responsibly. A marketplace fee calculator, for example, is only useful when the page makes clear which fee assumptions apply and that real fees can vary by account, category, and policy updates.
We also try to make sure each calculator page helps a seller decide whether the tool fits their question, rather than simply asking them to enter numbers and take the answer at face value.
How Article Pages Are Reviewed
Article pages are written to support real search intent and real seller planning. That means they should answer a practical question, offer examples or reasoning, and connect clearly to relevant calculators. We aim for articles that help a seller act, not articles that simply restate the page title in different words.
Before publishing or revising a guide, we try to check whether it includes a clear problem statement, useful examples, internal links, and a realistic explanation of how the idea applies to pricing, fees, shipping, inventory, or everyday seller planning.
Corrections and Updates
If a page is unclear, contains a weak explanation, needs a better example, or seems to create confusion, it may be revised. Corrections matter because Commerce Tally is meant to improve over time, not merely expand. We would rather strengthen an existing page than keep piling up thin ones.
The updated date on a page reflects the latest editorial revision we intend to show publicly.
Limits of the Site
Commerce Tally does not claim to be a tax professional, accountant, lawyer, marketplace, carrier, or financial adviser. A useful calculator or guide can still require adaptation for a specific account, category, geography, rate card, or policy change. Those choices remain the responsibility of the seller using the material.
Advertising and Independence
If Commerce Tally uses advertising or third-party services, that does not change the editorial goal of making the site more useful. We want calculators and guides to stand on their own merit. Trust pages, support articles, and calculator pages should still make sense even without promotional framing.
