2. What the tools do and do not do
Tiersova offers 61 free comparisons, each in 11 languages. Each one estimates total cost of ownership and remaps CSV column headers in your browser. The tools do not migrate accounts, workflows (for example Make or n8n JSON blueprints), credentials or databases, and a renamed header does not make a file import-ready.
3. How costs are calculated
Current total = current monthly cost × monthsAlternative total = alternative monthly cost × months + one-time switching costNet difference = current total − alternative total. A negative value means switching costs more over the chosen horizon, and the tool says so.
Reference price ladders (marked “Reference prices”) use published vendor price steps checked on 24 Oct 2026 against vendor pricing pages and recent third-party summaries. They are references, not quotes: prices change, differ by region, tax and contract, and some tiers above the last published step are extrapolated and flagged. Illustrative comparisons use editable linear estimates (base fee + rate per unit) that you should replace with your own quote. Nothing on this site is labelled “verified”.
Foreign exchange: business accounts such as Revolut Business only offer conversion without a fee within a plan's monthly allowance during market hours. Above the allowance a fee applies (0.6% on Revolut Business plans at the time of checking), and conversions outside market hours, such as weekends, carry an extra fee (1%). The calculators model both. This is not financial advice.
Display currency: vendors bill in their own currency (shown in the reference price tables). When you choose another currency, or your language uses one, amounts are converted with the ECB euro reference rates of 23 Oct 2026 (source). The rate used is printed under the result. Your bank or card rate and any FX fees will differ. Your currency choice is remembered in your browser's local storage on this device only.
4. Privacy
Calculator values and CSV text are processed in your browser by same-origin JavaScript. The site has no backend, accounts, analytics or cookies. The Content-Security-Policy sets connect-src 'none' and form-action 'none', which stops page scripts from sending data with fetch, XHR, WebSocket or forms. This is a strong technical restriction, not an absolute guarantee: browser extensions, your own copy/paste and the links you choose to follow are outside our control. Our static host (Cloudflare Pages) processes standard request logs; vendors you visit apply their own privacy notices. Please test with sample or anonymised rows and keep a backup of your original files.
5. Commercial links
Every outbound vendor link is labelled. Current link statuses: 61 × official_utm.
- official_utm: the vendor's official website with UTM tags. We have no confirmed commission on these links.
- verified_affiliate: an approved affiliate link. We may earn a commission at no extra cost to you. These links carry
rel="sponsored". - sponsored_referral: the operator's Revolut referral link. It carries
rel="sponsored"; the referral terms are set by Revolut.
Commercial relationships never change the arithmetic: results are calculated by the same open formula for every vendor, and negative results are shown. The public link register is at /affiliate-status.json.
6. Self-test artefacts
The build publishes qa-verification-report.json, qa-test-runner.mjs and qa-execution-log.txt. They are automated build self-tests, not an independent audit or certification.
