Mahalli is a desktop application for inventory and invoicing, built specifically around the B2B document chain used by Moroccan businesses. The name means “local” in Arabic, reflecting its focus on local commerce.

Built with Tauri v2, it combines a Nuxt 4 frontend with a Rust backend powered by SeaORM, delivering native performance with a modern UI. All data is stored locally in SQLite — no external server required.

The app supports multiple independent workspaces. Each workspace is a separate SQLite tenant database, hot-swappable at runtime. A persistent system catalog database tracks all registered workspaces and the active one, letting users create, clone, and switch between them without restarting.

Document Chain

The full Moroccan B2B workflow is covered end to end:

Quote / Devis — generate and send a quote to the client for approval
Customer Order / Bon de commande — convert an approved quote into a purchase order
Delivery Note / Bon de livraison — issue a delivery note when goods are dispatched
Invoice / Facture — generate the final billing document after delivery; invoices are immutable once finalized
Payment Tracking — record partial and full payments against invoices with outstanding balance per client
Credit Note / Avoir — issue a credit note against a finalized invoice for returns or pricing corrections

All printed documents carry the required Moroccan legal identity fields: ICE, IF, RC, and Patente/TP for both clients and the seller’s own profile.
