Extension Metadata

About this extension
Your own issuance date, your reception status, and what running late actually costs — €15 per invoice and €500 per missed e-report, each capped at €15,000 a year.


Click Add to Firefox on this page. Nothing to unzip, no developer mode - the free version runs right away.
  • Your issuance date, not the headline date — A GE or ETI had to start issuing on 1 September 2026; a PME or TPE starts 1 September 2027. The tool picks your date from your size and counts the days left, or the days you are already past.
  • Reception overdue counter — Reception of Factur-X, UBL and CII through a PDP has been mandatory for every French VAT-registered business since 1 September 2026, with no size waiver. The tool counts how many days you have been past that.
  • Both fines with their statutory caps — €15 per invoice that should have been electronic and €500 per missed e-reporting transmission, each capped at €15,000 per year. The tool applies each cap separately and shows the uncapped figure so you can see the gap.
  • The €250 to €500 e-reporting change — The original text set €250 per missed transmission; the 2026 Finance Act raised it to €500. The rate is a switch, so you can price both readings instead of trusting one number a chatbot gave you.
  • CSV export of the scenario (paid) — Writes your inputs, both fines, the caps and the dates to a CSV row you can keep, attach to a board paper or hand to your expert-comptable. Unlocked by the $60 licence key.
  • Deadline alarm (paid) — Sets a browser alarm for your issuance date so the 1 September 2027 PME cut-off does not arrive unnoticed. Unlocked by the same $60 licence key.

Permissions requested: storage, alarms


Free: the calculation in the popup, no key, no limit. Full version ($60): download the result as .csv and deadline reminders - one licence key per person or team seat. Get it: https://getreadystack.com/api/buy/cl/polar_cl_rUcabLiYLPONMzeXYuAQGJiFK7XT88JDITGyy4S5DVz


When you use the tool, the extension sends one anonymous count a day (the tool’s name only — no inputs, no personal data). Turn it off on the first page after install. Firefox asks first and sends nothing unless you allow it. A licence key is checked with the payment provider (Polar) only when you enter one.
