Editorial policy

Independence

Rankings and verdicts are decided before we look at affiliate terms. Partners can't review, edit or approve content. A product that pays us can still get a poor verdict.

Sourcing

Prices link to or name their source and carry a checked date. Finance and tax claims cite primary sources such as the IRS, HMRC or SBA.

Use of AI

We may use AI tools for research help and editing. Every page is checked, fact-verified and approved by a human before it's published, and every comparison links each price to the vendor's published pricing page, with the date it was checked. We don't claim hands-on testing we haven't done. We don't publish unedited AI drafts.

Finance, tax and legal topics

These pages are general information, not personal advice. We say so on the page and suggest checking with a qualified CPA, EA, accountant or solicitor for your situation.

Corrections

Report an error through the contact form. Confirmed errors are fixed promptly and the page's updated date changes.
