What Amarris Immo does

Amarris Immo is a France-based, fully remote online accounting firm specializing in furnished rental income taxation for individual French property investors. It is a subsidiary of Groupe Amarris (founded 1999 by Claude Robin), and it serves LMNP and LMP landlords, SCI holders, family SARLs, seasonal rental operators, gîte owners, and serviced-residence investors — addressing regime choice, amortization optimization, SIRET registration, annual declarations, and ongoing bookkeeping. The firm reports a base of 35,000+ investors covering 50,000+ properties, with 105+ dedicated collaborators in Guérande and Saint-Herblain.

The product surface is built around the Solo software and the Expert service. Solo (from €154/year after tax deduction) is a self-service SaaS with an automated amortization engine, FEC file generation, and one-click EDI-TDFC tele-transmission to the DGFiP, plus an embedded French IBAN current account (Compte Courant Immo) powered by Swan and a 2026-compliant electronic invoicing module. Expert (from €226/year) layers a dedicated chartered accountant on top of the same platform, handling amortization, signing declarations, and providing personalized fiscal optimization. The technology is published in-house by the group subsidiary FIZEN, supported by integrations with Stripe (payments), TELEDEC (EDI-TDFC), Zendesk (support), and OVH (hosting).

The revenue model is recurring subscription across Solo, Expert, and SCI (€46.50/month) tiers, supplemented by hourly consulting at €120/hr HT for out-of-scope work. Go-to-market is digital-first: SEO-optimized content, three free simulators, YouTube, webinars on Livestorm, and a referral (parrainage) program feed self-serve Solo acquisition, while Expert conversions route through free discovery appointments. A B2B partnership channel targets notaries, developers, and wealth advisors. Customer concentration is diffuse across SMB landlords; the firm holds no enterprise anchors and competes on vertical specialization rather than scale.
