SahaERP — Türkiye's first open-source ERP, built on .NET.

SahaERP is a multi-tenant, plugin-first ERP platform engineered for real businesses. Built as a .NET 10 modular monolith with a modern React 19 interface, it ships 17 production-ready modules spanning HR, payroll, finance, inventory, purchasing, sales, production (MRP), fixed assets, banking, counterparties, file storage, notifications, audit and reporting — all released under the OSI-approved CPAL-1.0 license.

Why SahaERP
→ Truly open source. Self-host it, read every line, extend it on your own terms.
→ Multi-tenant by design. PostgreSQL Row-Level Security enforces tenant isolation at the database, not just in code.
→ Plugin-extensible. A jurisdiction-neutral core; country compliance, industry verticals and payment integrations ship as plugins.
→ Modular monolith. Strict module boundaries with integration-event contracts — 80% of microservice benefits, none of the operational pain.
→ Trilingual UI with first-class Turkish, Arabic (RTL) and English.

Plugins on the way
• Turkish Statutory Accounting (e-Fatura, e-Arşiv, e-İrsaliye, SGK, KDV, Tek Düzen Hesap Planı)
• Paper & Cardboard Printing Press operations
• Netahsilat virtual POS collection & bank reconciliation
• SanalPos payment gateways (Garanti, İş, Akbank, Yapı Kredi, Param, iyzico…)

Stack
.NET 10 · React 19 · PostgreSQL · Wolverine · RabbitMQ · Valkey · SeaweedFS · Metabase — every dependency OSI-approved.

Who it's for
Founders, CTOs and finance teams who want enterprise-grade architecture without enterprise lock-in — SMEs scaling up, manufacturers, multi-branch retailers and service companies.
