Short version: ylishi.tools is free to use, with an optional Pro plan for advanced features. We earn commission from the Amazon Associates Program: a number of product links on our guides and tool pages are Amazon links carrying our associates tag ylishitools-20, and every one of them is marked rel="sponsored nofollow noopener". A commission never changes what we recommend or how we rate a tool, and the price you pay is the same as going to Amazon directly. This page is updated before any new affiliate link goes live.
ylishi.tools provides free Amazon seller tools — FBA profit calculators, fee tools, PPC helpers and guides — with no signup required. Running and maintaining them costs money, and one of the ways we cover that cost is affiliate commission. As of 22 September 2026 the only affiliate program we participate in is the Amazon Associates Program; we hold no affiliate or partner relationship with any other vendor. The free tools stay free; an optional Pro plan covers advanced features.
This page explains what that means, which links are affected, and how we keep our recommendations honest. It is written to comply with the U.S. Federal Trade Commission's Guides Concerning the Use of Endorsements and Testimonials in Advertising (16 CFR Part 255).
An affiliate link is a normal link that carries a tracking identifier. If you click it and later buy a paid subscription from that vendor, the vendor pays us a percentage of the sale. The price you pay is the same as going to that vendor directly — in some affiliate programs the vendor also gives readers a discount, but the Amazon Associates Program does not, so an Amazon link never costs you more.
Affiliate links on this site are Amazon links carrying our Amazon Associates tag ylishitools-20. At the time of writing there are 21 such links across 7 pages:
| Page | Affiliate links |
|---|---|
blog/amazon-fba-vs-fbm-guide.html | 4 |
guides/amazon-fba-prep-guide.html | 4 |
guides/fba-fee-optimization-checklist.html | 4 |
guides/amazon-packaging-design-guide.html | 3 |
tools/dimweight/index.html | 3 |
tools/cpc/index.html | 2 |
eu-fba-calculator/index.html | 1 |

They point to Amazon search or product pages. Every one carries rel="sponsored nofollow noopener" — the standard machine-readable signal for sponsored and affiliate links — and opens in a new tab. We update this page before any new affiliate link goes live.
Every outbound link to a non-Amazon third-party vendor points to that vendor’s public pricing, documentation or product page and carries no tracking identifier: we receive nothing whether you click it, subscribe through it, or buy from it.
Our free tools, calculators, guides and blog posts are not affiliate links and never have been. The core tools, calculators and guides on this site are free to use; an optional Pro plan covers advanced features.

We hold no affiliate or partner relationship with SellerSprite, Helium 10, Jungle Scout, AMZScout, Keepa or any other vendor named on this site, and we earn nothing from them. This table is the authoritative list of the programs we are in and it contains exactly one entry — Amazon. We add or remove vendors here as our arrangements change: if a vendor is not listed, assume we are not earning from it. Any article that compares several tools will state which of them, if any, pay us.
ylishi.tools is an independent third-party tool. Amazon, FBA and all related marks are trademarks of Amazon.com, Inc. or its affiliates. ylishi.tools is not affiliated with, endorsed by, or sponsored by Amazon.com, Inc. We do participate in the Amazon Associates Program: some links to Amazon on this site carry our associates tag ylishitools-20 and earn us a commission on qualifying purchases. This never changes the price you pay, and it does not affect our rankings or verdicts.
Pricing, plan limits and feature availability for third-party tools are set by those vendors and change without notice. Figures quoted on this site reflect what was published at the time of writing — always confirm the current price on the vendor's own pricing page before you buy.
If you think a disclosure here is incomplete, or you believe a recommendation was influenced by a commission, tell us: [email protected]. We will look into it and correct the page if needed.
