Custom ERP for Manufacturing
Replace rigid, generic ERP modules with a purpose-built system designed around how your factory actually operates.
The Challenge
Manufacturing companies frequently find themselves trapped between two poor options: over-customizing a generic ERP like SAP or Oracle until it becomes an expensive maintenance nightmare, or forcing production teams to adapt their workflows to software that was never designed for discrete or process manufacturing. Critical functions such as bill-of-materials versioning, shop floor scheduling with real-time machine data, and multi-stage quality holds are either absent or buried behind clunky workarounds. The result is production planners maintaining shadow spreadsheets, quality teams relying on paper forms, and finance closing the books days late because cost roll-ups require manual reconciliation across disconnected modules.
Our Solution
MicrocosmWorks can build a custom ERP specifically tailored for manufacturing operations, designed from the ground up around the client's production model rather than bolted onto a generic framework. The system covers the full manufacturing loop — from sales order intake and production planning through shop floor execution, quality management, procurement, and cost accounting — with every module sharing a single, real-time data layer. Industry-specific constructs like multi-level BOMs with engineering change orders, finite-capacity scheduling, and lot/serial traceability are first-class features, not afterthoughts. A phased rollout strategy ensures the factory never goes dark during migration from legacy systems.
System Architecture
The platform is built on a modular monolith architecture with clear domain boundaries, enabling independent evolution of each functional area while avoiding the operational overhead of premature microservices. A real-time event bus propagates state changes between modules, and an integration layer connects to shop floor IoT devices, supplier portals, and logistics providers.
- Production Planning Module: Finite-capacity scheduling engine that accounts for machine availability, tooling constraints, labor shifts, and material lead times to
generate optimized production sequences.
- Bill of Materials Engine: Multi-level BOM management with revision control, engineering change order workflows, substitute material logic, and phantom assembly support.
- Shop Floor Control: Real-time work order tracking with barcode/RFID scanning, operator dashboards, machine data integration via OPC-UA, and automated labor time capture.
- Quality Management System: Inspection plan configuration, statistical process control charts, non-conformance tracking, CAPA workflows, and certificate-of-analysis generation.
- Cost Accounting Engine: Standard and actual cost roll-ups by work order, variance analysis (material, labor, overhead), and automated journal entries to the general ledger.
- Procurement & Vendor Portal: Purchase requisition-to-PO automation, vendor scorecards, blanket order management, and a self-service portal for suppliers to confirm orders and submit invoices.
