Contact SellerTools Hub
We welcome corrections, tool requests, article suggestions and business inquiries related to ecommerce seller education.
What to include
- The page URL you are referring to.
- A short description of the correction, question or tool request.
- Any official marketplace source we should review if a fee or policy appears outdated.
Editorial corrections
If a calculator explanation, guide or article contains an outdated assumption, we review correction requests and update pages when the change improves accuracy for sellers.
Tool and article requests
If you want us to cover a specific seller workflow, include the marketplace, the type of product and the decision you are trying to make. Useful examples include pricing a TikTok Shop bundle, estimating Amazon FBA profit after returns, comparing Shopify CAC with contribution margin or planning whether a product can afford paid traffic.
Response expectations
We read messages related to site accuracy, user experience and ecommerce education. We cannot provide private account support for TikTok, Amazon, Shopify, Google or payment providers, and we do not review confidential seller data through this contact page. For account-specific issues, use the official support channel of the relevant platform.
Business inquiries
Relevant business inquiries may include data partnerships, educational content collaborations and sponsorship questions that fit ecommerce sellers. Any advertising or partnership relationship must remain separate from our calculator formulas and editorial explanations.
How to turn this page into an operating habit
Do not use this resource only once. The value comes from repeating the same review after new information arrives. Start by recording the current assumption, the source of the number and the date it was checked. Then decide which number is most likely to change the conclusion. For Contact SellerTools Hub, the most important lens is usually product economics. That means the seller should review selling price, product cost, fulfillment cost, platform fees, return allowance and ad spend before treating the result as reliable.
A product that appears profitable at gross margin level can become weak after fees, returns, discounts and acquisition cost are included. A good review does not need to be complicated. It needs to be consistent. Use the same rows, the same definitions and the same decision threshold each time. When the product changes, update the assumptions rather than starting from memory.
Seller review notes
The next practical step is to build base, conservative and scale scenarios before making a larger commitment. Write down the answer in a short note: continue testing, improve the offer, reduce spend, adjust price, delay inventory or pause the product. This written decision matters because ecommerce dashboards can change quickly. Without a note, it is easy to forget why a product was approved or rejected.
If several people work on the same store, use the note as a shared decision record. The operator, media buyer and sourcing person should be able to see the same assumptions. That makes the resource more useful than a private calculation because it turns numbers into a team workflow.
Questions to answer before acting
- Which input is estimated rather than confirmed by real store data?
- What happens if acquisition cost is 20% higher than expected?
- What happens if returns, refunds or shipping cost increase?
- Is the decision based on one product, one campaign or enough data to be trusted?
- What specific action will be taken if the result is below target?
