A simple, very affordable French invoicing tool for freelancers, still young and run by an individual vendor, with a deliberately narrow scope.

Selki is a French invoicing and quoting tool, built by an independent developer, designed for freelancers, sole traders, and small agencies. It bets on simplicity for producing compliant quotes and invoices without unnecessary complexity.
You create flexible quotes, turn them into invoices, and track payments and revenue from a clear dashboard. The tool handles electronic signatures, online payment, a client portal, and the mandatory disclosures required under French rules. The goal is to cover a freelancer's day-to-day admin without the complexity of a full accounting suite.
Compared to Sellsy, a CRM and invoicing suite for SMEs, Selki is far lighter and cheaper, built for a solo operator. Compared to Indy or Freebe, geared toward accounting and tax filings for freelancers, it focuses on quotes and invoices. For full accounting, those tools go further.
It's a young product, run by an individual vendor, with a more modest ecosystem and integrations than established players. The free plan caps flexible quotes, and the scope stays deliberately focused on invoicing.
