Invoices and a tax reserve for Moroccan auto-entrepreneurs case study cover
Built for myselfLive

As an auto-entrepreneur, the tax is simple until the quarter ends and you realise you did not set enough aside.

Is this happening to you?

  • You build invoices from an old Word file.
  • You are never sure how much to keep aside for the quarterly payment.
  • You do not track how close you are to the annual turnover limit.
  • You do not want to give your figures to another online service.
The real tool: an invoice prepared, receipts entered, and the quarter's reserve calculated.

Open AE Tool.

How it works

  1. Prepare an invoice. In French or English, in MAD, USD or EUR, then print it or save it as a PDF.
  2. Enter what you were paid. Month by month, by activity type.
  3. See the quarter. The tool separates money already received from estimates, and shows the tax to plan for.
  4. Know what to set aside. It shows how much is already reserved and what to transfer each month.
  5. Watch the limits. It compares your year to the annual ceilings and flags the 80,000 MAD same-client rule.

Decisions that make it safe to use

  • Your figures stay on your device. No account, no server, no database.
  • It shows its working. Every amount comes with its breakdown, and the rules it is unsure about are labelled as estimates.
  • It is a planning tool, not tax advice. It says so, and points to the official sources.

What it runs on

  • React and Vite: the app, which runs entirely in your browser.
  • Browser storage: keeps your entries on your own device.
  • The 2026 tax code: the rates and ceilings the calculator uses, with sources listed.
