mkarrit/facturation-devis

Facturation & Devis is a WPF desktop application for managing a small business’s sales cycle, backed directly by PostgreSQL rather than an application server. A user maintains clients and articles, prepares and sends a quote, converts an accepted quote into an invoice, issues it with a definitive number, then records payment or creates a credit note. The graph captures the sampled client and invoice paths plus documented quote/PDF and dashboard capabilities. Some view-model and repository wiring is represented at directory level because those sources were not sampled.
