Contact SellerMaths

0. Public contact email

For public-site feedback, corrections, and calculator suggestions, use sellermath.help@gmail.com. The most useful emails name the exact page URL, explain what looks wrong or missing, and cite the public source that should support the update.

• Use sellermath.help@gmail.com for source-backed corrections, broken-link reports, and calculator suggestions.
• Include the exact page URL and the assumption, output, or section you want reviewed.
• When possible, include the public source document and the date the rule was checked or changed.

1. What this page is for

SellerMaths is a static-first calculation project, so the most useful contact requests are not generic support tickets. Good messages point to a specific page, formula, fee rule, broken link, or source update that affects what a seller sees on the site.

• Report a fee change or pricing-policy update that affects an existing calculator or comparison page.
• Flag a page that seems to use the wrong country scope, plan scope, or date scope.
• Suggest a missing calculator, guide, compare page, or template that would solve a real seller pricing problem.

2. What to include in a useful message

The fastest way to make feedback actionable is to remove ambiguity. A vague message saying that a page looks wrong is much less useful than a message that shows the affected URL, the exact assumption in question, and the public source that should replace it.

• Include the exact page URL and the section or output that looks wrong.
• State the country, currency, plan, payment method, or seller type that the issue applies to.
• When possible, include the official source document and the date the rule was last verified or changed.

3. Best reasons to contact SellerMaths

Not every kind of feedback has the same value. The strongest messages are the ones that help keep the calculators current, scoped correctly, and easier to use during real pricing decisions.

• A platform changed a fee, threshold, processing rule, or ad policy.
• A page needs a better assumption note, clearer worked example, or tighter wording around scope.
• A broken internal link, dead source link, or inconsistent figure appears on a live page.

4. What SellerMaths cannot do through contact requests

SellerMaths is not platform support and does not have access to private shop accounts, payout dashboards, tax filings, or payment-processor back ends. The contact page is for public-site issues and source-backed corrections, not for account troubleshooting.

• The site cannot review private invoices, statements, or payout screenshots as if it were your platform support team.
• The site cannot give personalized legal, tax, or accounting advice for a specific business situation.
• The project does not promise consulting, custom spreadsheet builds, or guaranteed response times through public site feedback.

5. Why source-backed corrections matter

SellerMaths depends on public documentation that can change by country, date, plan, category, payment method, or seller status. A correction tied to the underlying source is much more valuable than a correction tied only to memory or a single isolated order result.

• Public fee docs help show whether a change is global or limited to one region or payment path.
• Source-backed updates are easier to verify, scope, and roll into calculator rules without adding new ambiguity.
• Good correction requests make the whole site more trustworthy for the next seller using the same page.

6. Before sending feedback

A quick self-check can prevent false alarms. Many calculator differences come from country scope, payment method, shipping treatment, ad participation, plan choice, or whether a flat fee and a percentage fee were both modeled.

• Check the page assumptions and worked example before concluding the page is wrong.
• Confirm that you are comparing the same country, currency, and seller setup as the page itself.
• If you are comparing against a live platform result, note whether taxes, shipping, refunds, or one-off adjustments were included.

7. Related pages to review first

Some questions are easier to solve by reading the explanation page that sits behind the calculator. If the issue is really about pricing logic rather than a broken rule, the pages below usually answer it faster than a generic contact request.

• Read About SellerMaths if you want the project scope and trust model first.
• Use the profit and pricing guides if the real issue is how to model margin, break-even, or post-fee pricing.
• Use a platform-specific calculator first when you need to isolate whether the issue is in one fee layer or in the whole selling model.

Assumptions

• SellerMaths contact requests should focus on public-site issues, source-backed corrections, broken links, and calculator or content suggestions.
• SellerMaths is not connected to private seller accounts and cannot verify account-specific invoices, payouts, or tax records through this page.
• The project does not promise guaranteed response times, consulting deliverables, or personalized tax, legal, or accounting advice.
• The most actionable contact requests identify the exact page URL, scope, and source document involved.
