Last updated: 8 August 2026
How to reach us, what to expect, and answers to the questions we are asked most often. If your question is not covered here, email us — a person reads every message.
1. How to reach us
- Email: contact@tarslimited.com — the fastest route, and the one we prefer for anything involving your account, because we can verify who is writing.
- Phone: +44 7576 034 999.
- Support is available in Turkish and English.
- We aim to reply to email within one business day. Security reports are handled ahead of everything else.
When you write about a problem in the app, telling us your account email, the page you were on and roughly when it happened lets us find the matching server records straight away.
2. Getting started
TrueMargin calculates the real net profit and margin of what you sell on Amazon, across your stores and currencies. You can start with a free account and bring your data in two ways.
- Connect your Amazon seller account through the Selling Partner API from Settings, then Integrations. You authorize us on Amazon’s own consent screen; we never see your Amazon password.
- Or upload a CSV export of your orders if you prefer not to connect an account.
- Add your cost of goods and any other costs, since Amazon does not know what you paid for your stock. Without it, profit figures are incomplete.
3. Why your figures can differ from Amazon’s reports
This is the question we are asked most, and the answer is usually timing rather than an error.
- Amazon reports referral and FBA fees separately from the order, and only once a shipment settles. Until those fees post, a recent order can appear with no fees deducted, which makes its profit look higher than it will end up being.
- Cost of goods and other costs come from you. If they are missing or out of date, the margin will be wrong no matter how accurate the rest is.
- Amounts in other currencies are converted using daily rates, so a converted total will rarely match a figure Amazon states in the original currency to the cent.
TrueMargin is decision support. Your own bookkeeping, financial reporting and tax filings remain your responsibility — see the Terms of Service.
4. Account, plans and billing
- Plan pricing is published at https://truemargin.com.tr/fiyatlandirma. You build your package from the modules you need rather than choosing a fixed tier.
- Paid plans are billed through Stripe. Your full card number never reaches our servers.
- You can cancel from your billing settings; cancellation stops the next renewal.
- Product lookups consume credits, and different lookups cost different amounts depending on how much data you ask for. The app shows the cost and your remaining balance before you spend.
5. Your data and privacy
- We do not collect or store personal information about Amazon buyers.
- You can revoke our access to your Amazon account at any time from Amazon Seller Central; after that, no further data is synchronised.
- Deleting your account is immediate and cannot be undone. Export anything you want to keep first.
- The full detail is in our Privacy Policy at https://truemargin.com.tr/privacy.
6. Reporting a security issue
If you believe you have found a vulnerability or any unauthorized access to data, email contact@tarslimited.com with “security” in the subject line. We treat these ahead of all other messages and follow a written incident response plan, which includes notifying Amazon within 24 hours of any incident affecting data obtained through the Selling Partner API. Please give us a reasonable chance to fix an issue before disclosing it publicly.
