Frequently asked questions about Zuelen tools
Pricing, privacy and the limits of the calculators, in brief.
Are the Zuelen tools free?
Yes. The VAT calculator and the CCSS estimator are free and work without an account. The invoice maker is part of Zuelen: the free Basic plan includes 3 invoices per month.
Are the amounts I enter stored?
No. The VAT calculator and the CCSS estimator run locally in your browser; the amounts you enter are not sent to Zuelen.
How do I know the rates are up to date?
Each tool shows its last verification date and links to the official sources it uses: the AED for VAT and the CCSS for social-security contributions.
Do the results replace professional advice?
No. The tools apply the published official rates and parameters but do not determine your tax or social-security situation. For a specific case, contact the AED, the CCSS or your fiduciaire.
