Spending more on SAP licensing and consultants than the system saves you in efficiency?
Production orders, inventory, and finance living in three different systems that don't talk to each other?
Non-standard costing models or multi-site workflows that no off-the-shelf ERP handles cleanly?
Legacy on-premise ERP that costs more to maintain each year than replacing it would?
Custom ERP Software for Manufacturing
Off-the-shelf ERP is built for the average manufacturer. If your operation isn't average -- and most aren't -- you spend more time working around the software than working with it.
We build custom ERP systems designed around your actual workflows: your bill of materials, your production order logic, your supplier relationships, and your cost structure. No modules you don't use. No workarounds for processes the vendor didn't anticipate.
BOM-driven production order management and material requirements planning built for your product structure
Real-time multi-site inventory with barcode and RFID scanning, lot tracking, and safety stock alerts
Supplier portal, purchase order automation, and goods receipt matching in one system
Job costing, overhead allocation, and variance analysis that matches your actual cost structure
RaftLabs builds custom ERP software for manufacturers whose operations don't fit what SAP, Oracle, or Microsoft Dynamics were designed for. A custom manufacturing ERP covers production order management, BOM-driven material planning, multi-site inventory, procurement, job costing, and finance in a single system built around your actual workflow. Most manufacturing ERP projects deliver an initial production-ready module in 12 to 16 weeks at a fixed, agreed cost.

When off-the-shelf ERP stops being enough
Off-the-shelf ERP vendors build for a statistically average manufacturer. That works until your operation diverges from the average -- unusual product configurations, non-standard costing models, multi-site plants with different workflows per location, or a legacy on-premise system that was never replaced because the pain of replacing it felt worse than the pain of living with it.
Custom ERP is not a bigger project than buying and implementing SAP. For mid-size manufacturers, a custom build is often faster and significantly cheaper when you factor in licensing, consultant fees, and the years of customisation work that follows a standard ERP go-live. The difference is that a custom system is built once for your operation and owned by you, not leased at an annual fee that rises every year.
We have integrated with SAP, Oracle, Microsoft Dynamics, and several industry-specific ERP systems. We know what these platforms do well and where they fail mid-size manufacturers. When a full replacement isn't right, we build integration layers that extend what you have. When replacement is the right call, we scope it in phases so you go live on what matters first and expand from there.
What we build
Production order management
We build BOM-driven production order management that covers the full order lifecycle from raw material to finished goods. Material requirements planning runs against your live inventory and open purchase orders so planners see accurate availability before releasing orders to the floor. Work order release, operator assignment, and actual versus planned cost variance are tracked per order. Partial completions, rework orders, and production splits are handled without workarounds. Order status writes back to your inventory and finance modules in real time so nothing has to be reconciled manually at period end.
Inventory and warehouse management
Real-time inventory across multiple sites with location-level stock visibility for raw materials, work in progress, and finished goods. Barcode and RFID scanning for goods receipt, pick, transfer, and dispatch -- reducing manual entry and the errors that come with it. Lot and batch tracking from receipt through production to despatch, so traceability queries run in seconds rather than hours. Safety stock alerts and reorder point logic keep your procurement team ahead of shortages. Stock valuation by lot, batch, or standard cost is calculated automatically and reconciled to your finance module.
Procurement and supplier portal
Purchase orders generated automatically from MRP signals or raised manually by procurement, routed through your approval workflow before being sent to suppliers. A supplier-facing portal lets your vendors acknowledge orders, confirm delivery dates, and flag shortfalls before they affect production. Goods receipt matching against purchase orders and delivery notes catches discrepancies at the point of receipt, not at invoice time. Supplier performance is tracked against on-time delivery, quantity accuracy, and quality rejection rates so you have data for supplier reviews that goes beyond gut feel.
Finance and cost accounting
Job costing and standard costing models configured to match how your operation actually accumulates cost. Manufacturing overhead allocation by machine hour, labour hour, or a custom driver. Variance analysis at the production order level shows the gap between standard cost and actual cost for materials, labour, and overhead. The finance module integrates with Xero, Sage, QuickBooks, or a custom general ledger so accountants work in the tools they know without rekeying data from the production system.
Sales order and customer management
Customer order entry with delivery scheduling against your current production capacity and confirmed material availability. Customer-specific pricing, discount structures, and contract terms are stored against each account and applied automatically at order entry. Production capacity checks on promising delivery dates so your sales team commits to dates your plant can actually meet. Despatch note and invoice generation from the confirmed shipment, with the full order and production history attached for customer queries and dispute resolution.
Multi-site reporting and dashboards
Consolidated reporting across all plants with site-level drill-down for production, inventory, procurement, and finance. Site-level profit and loss showing production cost, overhead, and margin per location. Inter-company stock transfers between sites with automatic cost and inventory adjustment. Role-based dashboards for floor supervisors, production planners, procurement managers, finance controllers, and senior management -- each showing the metrics relevant to their job without data that isn't. Reports run from live data, not from a nightly extract, so numbers are current when decisions need to be made.
Frequently asked questions
The decision usually comes down to three factors: configuration limits, total cost, and how standard your operation is. SAP and Dynamics are built for a broad market, which means they cover common manufacturing scenarios well but handle edge cases through expensive configuration or customisation. If your BOM structure, costing model, or production routing doesn't fit the standard data model, you spend months in a configuration project that ends with a system that still requires workarounds. For mid-size manufacturers with $5M to $100M in revenue, the licensing and implementation cost of a tier-one ERP often exceeds the cost of a custom build that is designed specifically for your operation, owned outright, and doesn't require annual licence renewals.
We use a phased approach that gets you onto a working system faster than a big-bang cutover. The first phase -- typically production order management, inventory, and basic procurement -- delivers in 12 to 16 weeks. Finance integration and supplier portal follow in a second phase. Full replacement, including historical data migration and advanced reporting, runs 6 to 12 months depending on the complexity of your current data and the number of integrations to external systems. You are on the new system and generating value before the full project is complete. The old system stays available for reference during the transition period so there is no cliff-edge cutover risk.
Yes, and this is often the right starting point. Many manufacturers need one part of their ERP replaced or extended -- a production management module bolted onto their existing finance system, or a supplier portal that integrates with an existing ERP they're otherwise happy with. We build integration layers using REST APIs, database-level connectors, or file-based exchange where APIs aren't available. The integration spec is documented before development starts so you know exactly what data moves where and when. This approach lets you replace the parts of your current system that cause the most pain while keeping what works.
A focused ERP module -- for example, production order management and inventory for a single site -- typically runs $40,000 to $80,000 depending on scope and the number of integrations required. A full custom ERP covering production, procurement, finance, and multi-site reporting runs $120,000 to $250,000. We scope every project before pricing it so you know what you're getting before you commit. We don't do hourly billing -- fixed project costs only, with milestones tied to working software deliveries rather than time spent.
