Your business works in flows. Your ERP should too.

SIX ERP is an integrated ERP system developed by SIX MS Ltd, a Bulgarian software company founded in 2009. It connects customers, orders, purchasing, inventory, production, projects, employees, service, delivery and finance in one platform with web and mobile apps. Processes are configured around how each company actually works.

Yes. SIX ERP has extensive APIs for integrating third-party applications, automating business processes and building custom functionality.

Yes. StockFlow tracks stock by location across multiple warehouses, guides warehouse operations and gives full traceability. It connects to PurchaseFlow for replenishment and SalesFlow for availability and delivery, and supports methods such as ABC analysis and safety stock.

Yes. SIX is available in Bulgarian and English, German, Spanish, Italian and Greek.

Yes. Choose the SIX Flows you need today and connect more as you grow. All flows share the same data, so adding one later does not require migrating or re-implementing.

SIX ERP is configured around your processes instead of forcing standard ones. Every process is mapped in detail before implementation (“no gap policy”), modules are connected on demand, and one vendor delivers software, consulting, implementation and support.

Cost depends on the flows you choose. The number of users and the scope of implementation. SIX Starter package for simple business operations in a 5 User Pack can start as low as EUR 999 per annum, which is 16.65 Euro per user and month. 

Yes, SIX ERP FinanceFlow supports Bulgarian accounting and invoicing. For SAF-T, see: SAF-T in Bulgaria: Why Accounting Software Is Only Part of the Solution

Yes. ServiceFlow connects service requests, scheduling, technician dispatch, customer assets, spare parts, mobile execution, customer approval and invoicing. It suits companies from a handful of technicians to large field teams, for example HVAC, installation and maintenance businesses.

Yes. ManufacturingFlow manages bills of materials, material requirements, production planning, shop-floor execution, quality control, warehouses and costing in one traceable process, from customer order to finished product. It supports both make-to-order and make-to-stock production. You can even pre-produce item in Bucket Orders for timely delayed productions. Or – you might work in a hybrid model that includes MTO,MTS and Buckets – all at once.

A single-flow implementation for a small company typically takes 3 to 4 weeks; a multi-module manufacturing rollout takes 4 to 8 months. Duration depends on the number of flows, data migration volume and the amount of customization.

Move in phases: map your current processes, import master data (products, customers, suppliers), launch one core flow such as inventory or sales, train users, then add further flows. SIX consultants run this process and keep Excel and ERP data aligned during the transition. See our guide: How to Move from Excel to ERP in Phases

Yes. Small businesses can start with one or two flows, for example SalesFlow with StockFlow to connect sales and warehouse, and expand as they grow. There is no need to buy the full suite up front.

SIX ERP is built for manufacturing, sales and distribution, wholesale, services and field service companies. It fits small and medium businesses as well as enterprises. Each industry gets its own process setup on the same platform, so a 10-person service company and a multi-warehouse manufacturer use the same system, configured differently.

SIX ERP covers ERP, CRM, HR management, warehouse management (WMS), business intelligence dashboards, finance and accounting, manufacturing, logistics and field service management in one system. Each area is delivered as a SIX Flow module, and all modules share the same data.

The SIX Flows are the modules of SIX ERP: ServiceFlow, ManufacturingFlow, SalesFlow, CustomerFlow, PeopleFlow, PurchaseFlow, StockFlow, ProjectFlow, FinanceFlow and AIFlow. Start with the flow that fixes your biggest pain: ManufacturingFlow for production planning, ServiceFlow for technicians and service requests, StockFlow for warehouses and inventory, SalesFlow for leads and orders. Add the others later without re-implementing.

Yes. The SIX ERP mobile app lets field technicians receive jobs, update status, record work and parts, and get customer approval on site. Office teams see the same data in the web app in real time, from service request to invoicing.

SIX provides post-integration support, continuous updates and ongoing training. You choose your SLA, response times and support channels.

SIX handles the full ERP journey: pre-integration consulting and process mapping, configuration and integration, customization, user training, and post-go-live support with continuous updates. One team is responsible for the project from analysis to support. SIX supports you on-site throughout Bulgaria and Europe.
