Who is behind CrowFlip. How our content is made.
Operator and editorial responsibility

Provider details in the legal noticeSources and AI assistance
AI assists us with drafting, structuring, translating and revising content. This assistance does not replace reliable sources. For information that can change, such as marketplace rules and fees, guides link to the primary sources used, including marketplace help pages and public authority information.
Source checking means comparing statements with the cited sources. It does not mean approval by a tax or legal adviser, or a claim to professional qualifications. Our content provides general information, not individual legal or tax advice. Decisions about your own circumstances may require qualified advice.
What our examples demonstrate
Demo cases and calculation examples use stated assumptions. They explain a calculation or workflow; they do not prove a completed sale, market price or achievable profit. A calculator screenshot only demonstrates the displayed result for the entered values.
Our selling calculators subtract entered costs from sale proceeds. The resulting cash surplus is not taxable profit. Costs not entered, working time, returns or taxes can change the economic outcome. Check each calculator's assumptions and enter your own costs.

The first date on an article is its publication date. “Updated” identifies a content revision; the date does not guarantee that external rules have remained unchanged since then. The relevant guide includes notes about the dates of individual sources or examples.
If you spot an error, send us the page URL, the relevant statement and a supporting source if available. Hide personal information in screenshots. This helps us investigate and correct the content where needed.
