Most manufacturing operations run on ERP platforms built for generic business workflows rather than factory operations — leaving production scheduling, shop floor visibility, BOM accuracy, and costing as persistent gaps that are filled with spreadsheets and manual workarounds. Perimattic builds custom manufacturing ERP systems engineered to the specific production processes, inventory structures, and integration landscape of the operation: procurement through production, costing through financial reporting, connected to MES and supply chain systems throughout.

Custom manufacturing ERP development is the design, engineering, integration, and support of software platforms that manage the full manufacturing operation — procurement through production, inventory through despatch, costing through financial reporting. A manufacturing ERP controls the complete operational picture: supplier orders and goods receipt, BOM management and engineering changes, work order release and shop floor scheduling, real-time material consumption and production output, actual cost capture at work order level, quality inspection integration, and finished goods inventory connected to financial reporting. Unlike generic business ERP platforms, a custom manufacturing ERP is engineered around the specific production processes, organisational structure, and integration landscape of the manufacturing business rather than requiring operations to conform to a standardised product's assumptions.
The challenge with most manufacturing ERP implementations is that generic ERP platforms impose their data models on the manufacturing operation. BOM structures do not match engineering reality, requiring manual workarounds to represent multi-level assemblies and routing sequences. Production scheduling operates on planned quantities rather than actual shop floor progress. Costing captures overhead allocations rather than actual production variance — producing COGS figures that finance cannot reconcile to what was physically consumed and produced in the factory. The gap between what the ERP records and what is actually happening on the shop floor becomes visible as inventory discrepancies, unexplained cost variances, and production decisions made on data that does not reflect current operational reality.
Perimattic builds custom manufacturing ERP systems starting from the actual production processes, BOM structures, and integration landscape of the operation. Every engagement begins with a manufacturing operations discovery that maps the existing workflows, costing model, and integration dependencies before any platform decisions are made. We design the ERP architecture around how the factory actually runs — the production model, the BOM complexity, the MES integration requirements, the financial reporting needs — and build each module to capture production reality rather than abstract it into a generic business data model.
Production visibility
Batch-updated production figures requiring end-of-shift data entry — shop floor status lags reality by hours, making operational decisions on outdated information
Production visibility
Real-time production tracking with shop floor events updating work order status, material consumption, and output quantities as they occur
BOM and routing accuracy
BOM structures and routings maintained separately from engineering — ECO changes propagate slowly, causing production to run against outdated specifications
BOM and routing accuracy
BOM and routing management integrated with engineering change workflows — ECO approvals automatically update production specifications and costing
Production costing
Standard cost accounting capturing overhead allocations rather than actual production variance — cost of goods figures that cannot be reconciled to shop floor reality
Production costing
Actual cost capture at work order level — material, labour, and machine time recorded at point of use, producing reconcilable cost-of-goods and variance reporting
Inventory accuracy
Periodic physical counts to reconcile ERP inventory against actual stock — inventory positions drift between counts causing production shortages and over-ordering
Inventory accuracy
Real-time inventory movements driven by shop floor events — goods receipt, material issue, and production completion update stock positions immediately
System integration
Manual data transfer between ERP, MES, and quality systems — re-keying creates errors and delays, and integration points are fragile and undocumented
System integration
API and event-driven integration across MES, quality, supply chain, and financial systems — production data flows automatically without manual intervention
The operational cost of a manufacturing ERP that does not reflect actual production workflows becomes visible as inventory discrepancies, unexplained cost variances, production decisions made on outdated data, and the proportion of management time spent reconciling what the system shows against what is physically happening on the shop floor.
Seven ERP capability areas covering the complete manufacturing operation — from custom platform development and production management through procurement, BOM, costing, quality integration, and legacy modernisation.
End-to-end development of bespoke manufacturing ERP platforms engineered to the specific production processes, BOM structures, inventory model, and integration landscape of the operation. Built around how manufacturing actually runs — not around the constraints of a generic business ERP that requires factory workflows to conform to a standardised product.
Work order management, production routing, shop floor scheduling, and real-time production tracking. We build the work order lifecycle from release through completion, the routing configuration that defines operations and machine assignments, and the shop floor visibility layer that reflects actual production status without manual data entry.
Supplier management, purchase requisitions, purchase orders, goods receipt, and supplier performance tracking. We build the procurement workflows that connect material requirements from production planning through supplier order placement, goods receipt confirmation, and invoice matching — with ERP integration throughout.
Bill of materials management, multi-level BOM structures, engineering change order integration, and real-time inventory management across raw materials, WIP, and finished goods. We build the inventory architecture that keeps stock positions accurate at the point of consumption and production rather than through periodic reconciliation.
Actual cost capture at work order level, standard vs. actual variance analysis, cost of goods sold reporting, and financial integration with accounting systems. We build the costing layer that connects shop floor events — material issues, labour bookings, machine time — to financial reporting without manual journal entries.
Quality inspection checkpoints integrated into production workflows, non-conformance management, CAPA workflows, and compliance reporting. We build quality into the production process rather than as a separate system, so inspection results, holds, and dispositions connect directly to work order status and inventory movements.
Integration of custom manufacturing ERP with MES, WMS, CRM, CAD/PLM, and financial systems. For existing ERP platforms constrained by age or architecture, we design an incremental modernisation path that delivers improvement at each phase without requiring a single cutover.
A structured six-stage process from free manufacturing operations discovery through production deployment and ongoing ERP platform support.
We map existing production processes, BOM structures, costing model, and integration landscape before any ERP architecture decisions. This free session produces a clear picture of current-state workflows — procurement through production, costing through financial reporting — and the integration dependencies that will define the platform.
We document production workflows, procurement cycles, inventory model, costing requirements, and integration dependencies in detail — identifying all ERP module requirements, MES integration points, financial system connections, and a phased delivery roadmap.
We design the platform architecture and build a proof of concept against the highest-risk component — typically the production costing integration or BOM management — to validate the approach and surface any technical risks before full development investment begins.
We develop ERP modules incrementally, delivering working production software at each phase. We build and integrate the platform with MES, supply chain, and financial systems throughout, implementing shop floor event capture and real-time inventory movements.
We test against real production scenarios, costing edge cases, integration failure modes, and BOM management workflows. We run user acceptance testing with production, procurement, and finance teams before any production go-live.
We deploy with CI/CD, monitoring, and runbook documentation. We provide training for production, procurement, and finance users and offer engineering retainers for ongoing ERP evolution, module additions, and performance optimisation.

Process manufacturers in chemical, food, pharmaceutical, and paint sectors operate with batch-based production, recipes, yield calculations, and by-product management — requiring ERP platforms that handle the non-discrete production model rather than forcing batch processes into discrete work order frameworks.
Mixed-mode manufacturers operate discrete assembly alongside process-based sub-assembly or material preparation — requiring ERP platforms that support both production models within a single integrated system rather than maintaining separate platforms for each mode.
Contract manufacturers manage production for multiple clients using client-owned materials, client-specific BOMs, and job-level costing — requiring ERP platforms with strict client inventory separation, job cost reporting, and customer-facing production visibility.
Engineer-to-order manufacturers design and build to unique customer specifications — requiring ERP platforms that integrate project management with production, support custom BOM creation per order, and track project costs from design through delivery.
Pharmaceutical, medical device, aerospace, and food safety manufacturers operate under regulatory frameworks — ISO 9001, IATF 16949, GMP, FDA 21 CFR Part 11 — requiring ERP platforms with full audit trails, electronic signatures, traceability, and compliance reporting built into production workflows from the outset.

Four structural advantages that separate manufacturing ERP systems built for real production environments from platforms that work in a demo but fail to reflect actual shop floor operations.
Every ERP engagement begins with mapping actual production workflows, BOM structures, and costing model before any platform decisions are made. This prevents the most common ERP failure mode: a technically correct platform that does not reflect how the factory actually operates, producing persistent gaps between the system record and shop floor reality.
A manufacturing ERP is only operationally valuable when correctly connected to shop floor systems, supply chain platforms, and financial reporting. We design structured integration architectures with proper event handling, retry logic, and reconciliation — not fragile point-to-point connections that fail silently under production load.
Actual cost capture at work order level, standard vs. actual variance, and COGS figures that reconcile to shop floor reality are built into the ERP from the start — not added as a reporting layer on top of a system that was never designed to capture production costs accurately.
The team that maps your production workflows and designs the ERP architecture also builds, tests, and deploys it. There is no handoff between a consulting team and a delivery team, no loss of manufacturing context between discovery and implementation. You work with the same engineering team from initial operations review through production deployment.
“A manufacturing ERP that fails to reflect actual production workflows creates a persistent gap between the system record and the shop floor reality — and that gap shows up as inventory discrepancies, unexplained cost variances, and production decisions made on data that does not match what is physically happening in the factory.”
Custom manufacturing ERP development is the design, engineering, integration, and support of software platforms that manage the full manufacturing operation — production management, procurement, inventory, BOM, costing, quality, and financial reporting — built around the specific production processes, organisational structure, and integration landscape of the manufacturing business rather than requiring operations to conform to a generic ERP product's data model and workflow assumptions.
SAP and Oracle cover enterprise business workflows comprehensively, but their strength is horizontal breadth across industries rather than depth in manufacturing-specific requirements. Manufacturers with complex BOM structures, multi-level production routing, actual cost capture requirements, or deep MES integration needs frequently find that standard ERP platforms require expensive customisation — or force operational compromises. A custom manufacturing ERP is built around the actual production model, costing approach, and integration architecture of the operation.
A custom manufacturing ERP can manage the complete manufacturing operation: purchase requisitions, purchase orders, and goods receipt for procurement; BOM management with multi-level structures and ECO integration; production planning, work order release, routing, and shop floor scheduling; real-time material consumption and production output tracking; actual cost capture at work order level with standard vs. actual variance; quality inspection integration at production checkpoints; finished goods inventory and despatch; and financial integration covering COGS, inventory valuation, and management reporting.
Yes. MES and shop floor integration is a core component of most manufacturing ERP engagements. We design and build structured integration layers — REST APIs, event-driven messaging, and OPC-UA where required — connecting the ERP with MES platforms, SCADA systems, and machine data sources. The integration typically covers work order release from ERP to shop floor, production reporting from MES back to ERP, material issue confirmation, and production completion events that drive inventory movements and costing entries.
We build actual cost capture at work order level: material issues recorded at point of consumption, labour bookings from shop floor time recording, and machine time from MES or manual input. The costing engine compares actual costs against standard costs at work order completion, producing variance reports that identify where production is running over or under standard. COGS figures are driven directly from actual production events rather than standard cost assumptions, producing financial reporting that reconciles to shop floor reality.
Yes. Multi-site manufacturing management is a common requirement. A custom manufacturing ERP can manage production, procurement, and inventory across multiple manufacturing sites with consolidated reporting, inter-site transfer workflows, and site-specific production rules. The platform can support different BOM structures, routing configurations, and costing approaches per site while providing consolidated production performance, inventory, and financial reporting across the manufacturing group.
We build multi-level BOM structures with version control, effectivity dates, and engineering change order integration. ECO workflows manage the transition from old to new BOM versions — capturing approval steps, effectivity dates, and the production scenarios (existing WIP, new orders) where each version applies. The BOM management layer connects directly to production planning and costing so that ECO approvals automatically update active production specifications and standard cost calculations.
Yes. Legacy ERP modernisation is often a more practical path than full replacement, particularly where the existing system holds significant operational data or where a full cutover carries production risk. We assess the existing system to identify which components are constraining the operation and design a phased modernisation path — adding API layers to enable integration with modern systems, migrating specific modules to a new platform, or replacing the system incrementally while maintaining production operations throughout.
Compliance requirements vary significantly by manufacturing sector. For regulated industries, we build the quality management integration, audit trail, and reporting capabilities required by ISO 9001, IATF 16949, GMP, or sector-specific regulatory frameworks. This includes inspection record management, non-conformance tracking with CAPA workflows, document control integration, and the audit trail that regulators require at product, batch, or work order level.
We follow a structured six-stage process: a free manufacturing operations discovery session mapping your production workflows, BOM structures, costing model, and integration landscape; process mapping and systems audit documenting current and target state in detail; ERP architecture and proof of concept validating the highest-risk component before full investment; module development and integration delivering working production software at each phase; testing and user acceptance against real manufacturing scenarios; and production deployment with monitoring, training, and ongoing engineering support.
Tell us about your manufacturing operation — the current systems, the production workflows that don't fit what you have, and the costing gaps that are creating manual reconciliation work. We will show you exactly how a custom ERP platform can replace the workarounds with automated, accurate workflows connected to your shop floor and financial systems.
