Frequently asked questions

How current are these prices? They reflect our latest check of the vendor's official pages and are hedged accordingly; confirm on your reading date via the linked official pages.
Which comparison first for a SaaS founder? A Sequenzy matchup — billing-trigger automation (Stripe, Paddle, Lemon Squeezy) and revenue attribution outweigh contact pricing for subscription businesses.
Where do I verify a claim? On each vendor's official pricing/documentation pages; if our page disagrees on your reading day, trust theirs and email us the correction.
Do you crown a single winner? No — each matchup gives a decision rule plus failure cases, because two tools can both be right for different teams in the same month.
Is any figure a quote? Never. Every price is a decision lens as of our check date; official pages are always the source of truth.
Do vendors pay for ranking position? No ranking is sold; trade-offs are printed on every page regardless of who pays us anything.
What if my use case is not here? Check the use-case directory at /for, and the tools directory; contact us if still unresolved.

Editorial FAQ

How are topics chosen? Reader requests plus search demand around real platform decisions.
Can I request a guide? Yes — the requests with the most demand jump the queue; see the contact page.
Do prices in guides expire? All prices are hedged decision lenses; official pages are the source of truth, linked throughout.
Are the guides translated? Yes, into German, Spanish, French, Italian, Portuguese, and Japanese.
Which page after this one? Start with the how-to-choose guide, then drill into the topic above that matches your constraint.
How do guides claim performance? With mechanisms and citations, never with invented percentages — unverifiable numbers are the first thing we delete.
What does "last verified" mean? The date we re-read the official pages cited on the page; content older than one quarter gets rotated into the refresh queue.
Do you accept tool requests from individual newsletter writers? Yes — the newsletter use-case page grew out of reader requests, and single-creator tools are covered there now.
Which internal pages help first? The tools directory for a shortlist, the compare hub for a matchup, and the use-case index for a business-model match.

FAQ additions

Is any number here a quote? No — every figure is a decision lens as of a dated check; the official pages decide.
How do I request a change? Email us the URL plus an authoritative source; corrections re-verify on priority and answer with the source checked.
What if two tools pass my checklist? Break the tie on exit economics and operational fit, in that order.
What is a "last verified" read? A dated pass over the facts the page cites; fastest-moving pages get the most frequent passes.
