Project manufacturing (Projektfertigung) describes production organised by customer-specific project rather than by standardised products. Each project has its own schedule, budget, deliverables and frequently its own engineering content. Project manufacturing overlaps substantially with engineer-to-order (ETO) — the boundary depends on the depth of per-project engineering. DACH industrial-equipment manufacturers, large-machinery builders, specialty industrial installations all run on project-manufacturing patterns.
Project-manufacturing characteristics
Customer-specific scope — each project specified by customer requirements rather than standard catalogue
Long duration — typically 3-24 months from order to delivery
Project-level accounting — P&L per project; revenue recognition by percent of completion or milestone
Progress billing — payment terms tied to milestones rather than delivery
Resource sharing — same specialised resources (engineering, manufacturing, installation) shared across multiple concurrent projects
Risk concentration — large projects carry significant project-specific risk; single-project losses can be substantial
Engineering involvement — varying depth from pure configuration through partial engineering to full ETO
Installation and commissioning — customer-site activities often part of project delivery
ERP requirements for project manufacturing
Project manufacturing demands specific ERP capabilities. Project structure: multi-level WBS with phases, milestones, deliverables; each level supporting cost-collection. Project accounting: per-project P&L, percent-of-completion revenue recognition, work-in-progress accounting. Project-specific BOMs and routings: created per project from configurable templates plus customer-specific additions. Capacity planning for shared resources: engineering, machining, assembly capacity allocated across concurrent projects. Procurement at project level: project-specific purchases with project-specific delivery scheduling. Change management during project: customer-driven scope changes during execution managed through structured change-orders with cost and timeline impact. Installation and commissioning workflow: customer-site activities tracked with completion documentation. Service handover: project completion triggers service-and-maintenance contracts.
Top ERP vendors for project manufacturing
Project-business-strong ERPs: IFS Cloud — deep project-business capabilities; abas ERP — native project structures for DACH machinery; proALPHA — integrated project and APS capabilities; Microsoft Dynamics 365 F&O with Project Operations — growing project-business capabilities; SAP S/4HANA with Project System; Oracle Cloud ERP with Project Portfolio Management. Specialist platforms: Infor LN for industrial-equipment project manufacturing; godesys, ams.erp, APplus, PSI Penta — DACH mid-market specialists. For DACH machinery and industrial-equipment project manufacturers, IFS Cloud, abas, proALPHA and SAP S/4HANA dominate the evaluation short-list.
Practical considerations
Three patterns. (1) Right-size the project structure: overly-granular WBS produces administrative overhead without operational benefit; overly-coarse WBS makes cost-tracking and progress-measurement difficult. Typical mid-market manufacturing projects: 20-100 WBS elements per million-EUR project. (2) Manage scope changes rigorously: every customer-driven scope change should produce a documented change order with cost-and-timeline impact. Without discipline, scope creep destroys project margin. (3) Capture lessons from completed projects: post-mortem reviews after project completion identify estimation errors, execution improvements, customer-relationship insights. Companies that systematically capture and apply these lessons improve project margins over time; those that don't repeat the same mistakes.
Project manufacturing versus ETO — what is the difference?
Substantial overlap. ETO specifically denotes per-order engineering as a defining characteristic. Project manufacturing more broadly covers any production organised by project, which may or may not include significant engineering. A configure-to-order machine delivered as a customer-specific project is project manufacturing without being ETO; a custom-engineered installation is both.
How does project accounting differ from product accounting?
Product accounting tracks costs by item; revenue recognised at delivery. Project accounting tracks costs by project; revenue recognised by percent-of-completion or milestone. Project margins are measured at project completion (or progressively during execution); product margins are measured per unit shipped. The accounting frameworks (IFRS 15, IFRS 11) prescribe specific revenue-recognition methods for long-duration projects.
Can SaaS ERP handle complex project manufacturing?
Increasingly yes. Microsoft Dynamics 365 F&O Project Operations, NetSuite OneWorld with project management, IFS Cloud all handle project manufacturing credibly. Pure multi-tenant public-cloud ERPs sometimes constrain the deep customisation that complex project manufacturers require; private-cloud or specialist mid-market platforms remain common for upper-end project manufacturing.
