Khosmos

Nous développons une application mobile de facturation destinée aux artisans du bâtiment. Celle-ci a pour but d'aider ces personnes à générer des devis, factures, attestations pour la TVA réduite et rapports d'intervention de manière intuitive et simplifiée. L'idée est de proposer à nos clients un plan mensuel, facturé au mois le mois, et un plan annuel, facturé une fois par an.

Can you vibecode this?

Yes

Flutter mobile app, Laravel backend, Stripe payments — all standard buildable stack. Quote creation, e-signatures, PDF generation, team permissions, and payment tracking are pure code. French e-invoicing compliance is a format spec, not a gatekeeper licence.

  • Problem

    Delayed quotes and complex admin cause missed sales for tradespeople.

  • Business model

    Monthly or annual subscription per account, with a per-seat add-on for extra users, billed through Stripe.

Moat

  • Switching costs
  • Regulatory & compliance barriers
  • Brand & trust

Why people pay Khosmos

15,000 artisans have quotes, invoices, and intervention reports stored in Khosmos. Leaving means losing that history. The app is already certified for France's 2026 mandatory e-invoicing reform, a compliance hurdle a fresh copy must still clear.

  • Product complexity

    Moderate

    The app generates quotes, invoices, intervention reports and French TVA attestations with e-signature.

  • Data

    Low

    No outside data sources are needed; all content is created by the user.

  • Integrations & infrastructure

    Low

    Standard hosted web app with Stripe billing and cloud document storage.

  • Human operations

    Low

    WhatsApp support and free team training are offered but do not gate the product.

  • Regulation / hardware

    Low

    The product must conform to French electronic invoicing rules, which are output formatting requirements.
