Quote-Part is a self-serve software product

Quote-Part is a browser-based application for owners of French family real estate companies (société civile immobilière, or SCI). More than 41,000 new ones were registered in France in the first half of 2026 alone, and several hundred thousand are active. Each one has to compute an annual property result, split it between its shareholders, and produce a few standard documents. Most small ones do this by hand, in a spreadsheet.

Quote-Part does the arithmetic and produces the documents. It is software, not a service. No work is performed by a human on the customer's behalf: no bookkeeping, no filing, no consulting, no review of the customer's figures. The customer enters their own data and the application computes and prints. This is stated in the terms of sale and in the application itself.

How a purchase works, end to end

1. The customer opens the app at quote-part.eu/app.html. The free tier runs immediately, with no account and no signup.
2. To lift the limits, they click Subscribe and pay on the Lemon Squeezy checkout, choosing one of three licence tiers.
3. Lemon Squeezy generates a licence key and emails it to them at the moment of purchase. Delivery is instant and happens entirely on your platform.
4. They paste the key into the app (Settings screen). The app calls api.lemonsqueezy.com/v1/licenses/validate, reads the variant name from your response, and unlocks the matching tier.
5. Nothing else is exchanged. There is no onboarding call, no email exchange, no deliverable produced by me.

What the application does

Licence tiers

One product, three variants, annual subscription, all prices VAT included. The only difference between tiers is the number of companies the licence covers.

Subscriptions renew annually and can be cancelled at any time from the customer's Lemon Squeezy portal. A 14-day refund window is granted even though access is immediate.

What is not sold here

To be explicit, since the distinction matters: I do not offer accounting, tax filing, legal advice, company formation, document review, or any other professional service, either on this website or elsewhere under this brand. The guides published on the site are free editorial content, written to explain the rules the software implements; they carry a notice stating that they are general information and not advice. Nothing on the site can be bought except the software licence.
