Custom machine building software development
Appfront builds custom business software for machine builders and special machinery manufacturers: from engineering and bills of materials to procurement with lead times, assembly planning, hours and project costing, and servicing of delivered machines. One system that follows an engineer-to-order job from quote through to delivery and maintenance, tailored to your way of working and integrated with your CAD, PLM and ERP environment. For machine builders, systems integrators, equipment manufacturers and OEM suppliers who want control over projects, margins and the installed base.
What is machine building software?
Machine builder software is the business software with which a machine builder manages an order from engineering through to handover and service. It brings together project management, bills of materials and revision control, purchasing with lead times, assembly planning, hours and project costing, and the maintenance of delivered machines in a single system. This is explicitly about the business operation around the machine: the machine builder's project process, not the control of the machine itself.
Special machine building is almost always engineer-to-order: every order starts with engineering and is to some degree unique. Standard packages assume repeatable production and force that process into a rigid mould, so teams fall back on loose spreadsheets alongside the system. Custom software development is built around the way you work rather than the other way round, and grows with you as you add new machine types, customers or service contracts. That way, a single project stays traceable from quotation through to the installed base, in one place.
This page is about the project organisation of the machine builder. If your question is mainly about the manufacturing process for parts, such as production planning, machine scheduling and machining, then see software for metalworking. Many companies do both, but these are different processes that call for different software. You can also read more about our broader approach to custom software development.
One file per machine
Engineering, bill of materials, purchasing, assembly, hours and service in one coherent project file. The project manager works from a single place and keeps track of everything, without retyping data from separate systems or folders.
Revisions under control
Changes made during engineering are recorded through revision control. Purchasing and the shop floor always work from the current bill of materials, so nothing is ordered or assembled based on an outdated drawing.
Margin and lead time in view
Booked hours and purchasing are measured against the costing, and open lead times are monitored. This way you see early where a project deviates from the estimate and can correct course before the margin or handover comes under pressure.
How we build your machine builder software
We work step by step and involve your engineers, production planners, buyers and service team early on. From a thorough exploration of your engineer-to-order process and your CAD, PLM and ERP landscape through to go-live and ongoing management, every step is aimed at software your team understands, trusts and uses daily on the shop floor.
We map out your process: quoting and costing, engineering, bills of materials and revisions, procurement, assembly and service. Together we determine which integrations with CAD, PLM and ERP are needed and where the biggest gains lie.
We design the data model around project, bill of materials, revision and machine, plus the screens for project managers, production preparation and service. We work out the integrations and permissions before we start building.
We build in short iterations with automated testing and monitoring. You see working versions along the way and help steer priorities and fit with daily practice in the office and in the workshop.
Controlled go-live with data migration and a safety net, followed by ongoing management, monitoring and further development as your machine types, customers or service contracts expand.
What machine builder software actually does
We tailor each application specifically to your process, machine types and integrations. Below are the features we most often deliver for machine builders and special machinery manufacturers working engineer-to-order.
Project management from engineering to handover
Every order as a project, from quotation and engineering through purchasing and assembly to testing and handover. For each project you see the status, the milestones and the open actions, so the project manager keeps control of scope, planning and lead time.
Bills of materials (BOM) & revision control
The bill of materials per machine and per revision, distinguishing manufactured parts, purchased parts and assemblies. Revision management records what changes and which open purchasing or assembly it affects, so you can always trace which revision was delivered.
Purchasing with lead times
Create purchase orders from the bill of materials and keep track of lead times. You see per project which parts are ordered, on the way or in stock, and which long lead times drive the assembly schedule, so critical purchasing goes out on time.
Assembly planning & progress
Schedule work orders and assembly steps against people and workstations, with visibility of the progress of every machine. Fitters report completion and log deviations, so production preparation and planning know in real time where the project stands. This connects to your wider production planning.
Time and project costing
Record engineering and assembly hours against project and work order, and set them against the costing. You see the estimated and actual costs per project and where the work deviates from the estimate, as a basis for sharper quotes and more reliable margins.
Service & installed base
For each delivered machine: the configuration, the revision delivered, the service history and the contractual agreements. Faults come in as tickets, are scheduled and resolved, and parts and hours used are recorded for invoicing or warranty.
Who we build machinery software for
Machine building encompasses several types of company, each with a project-driven process and its own place in the chain. For each of them we build software that suits their way of engineering, purchasing, assembling and servicing.
Machine builders & special machinery
Companies that engineer and build complete machines to order. The software follows the engineer-to-order process from quotation to handover, with bills of materials, revisions, purchasing and assembly in one coherent project file.
Systems integrators
Parties that combine machines, modules and installations into a working whole. They need oversight across multiple suppliers, sub-bills of materials and revisions, with clear agreements on who supplies and tests which part.
Equipment manufacturers
Builders of equipment and smaller series with configurations and variants. The software manages variants, bills of materials and costings, so a chosen configuration flows through to purchasing, assembly and the correct documentation.
OEM suppliers
Suppliers of modules and components within the chain. They need control over customer specifications, revisions and lead times, so they deliver reliably to their OEM customers and align their own purchasing and planning accordingly.

We build with a modern, maintainable web stack and connect to the systems you already use. For machine building, the most relevant are: your CAD and PLM environment, so that bills of materials and revisions from engineering flow through to procurement and assembly, and your ERP or accounting package for purchase orders, hours, project costing and invoicing. Where systems offer an API or export format, we build the integration so that data is recorded once and remains reliable in one place, so that drawings, bills of materials and the shop floor do not drift apart.

Security, documentation and the CE file
Machine builder software holds valuable business data: designs, bills of materials, costings, customer details and service contracts. That is why we build with security as a starting point. We work in line with OWASP security standards, with encryption in transit and at rest, role-based access so that not everyone can see costings or contracts, and rigorous audit logging of who changes what. We process employee and contact personal data in accordance with the GDPR.
The software can also support the documentation surrounding a delivered machine. Think of gathering drawings, certificates, inspections and manuals in a structured way and storing them per revision, so that the technical file for a CE marking remains complete and traceable. The substantive assessment and conformity relating to CE and the applicable machinery legislation remain your responsibility; the software supports your file management and is indicative on this point, not a substitute for legal or safety advice.

Frequently asked questions about machine builder software
Answers to the questions we are asked most often about custom software for machine building and special machine construction.
Machine building software is the business software that helps a machine builder manage an order from engineering through to handover and service. It brings together project management, bills of materials (BOM) and revision control, procurement of components with lead times, assembly scheduling, time and project costing, and maintenance of delivered machines in a single system. For bespoke, engineer-to-order machine building, custom software is designed around your own way of working, rather than forcing your process into an off-the-shelf package. This concerns the business operations surrounding the machine, not the control of the machine itself.
Machine building software centres on engineer-to-order projects: designing, engineering, assembling, handing over and servicing complete machines and systems, with bills of materials, revisions and an installed base you continue to service for years. Metalworking and machining software focuses on the manufacturing process of parts: production planning, costing per operation, machine loading of lathes and milling machines, and quality control of series production. Many companies do both, but these are distinct processes. For the manufacturing side we have a separate page on metalworking software; this page concerns the project organisation of the machine builder.
We build bespoke software. Every machine builder has its own way of engineering, costing, procuring and assembling, and works with its own mix of CAD, PLM and ERP systems. An off-the-shelf package rarely covers the engineer-to-order process, so teams fall back on loose spreadsheets alongside the system. Custom software fits your actual process and grows with you as you add new machine types, customers or service contracts. After an intake meeting, we agree together which functionality matters most and the order in which we build it.
With engineer-to-order, every order starts with engineering and progresses through procurement, assembly, testing and handover. The software gives an up-to-date view per project of its status, the bill of materials, outstanding purchasing with lead times, assembly progress, and booked versus estimated hours. Changes made during engineering are recorded through revision control, so procurement and the shop floor always work from the correct version of the bill of materials. This lets the project manager keep control of scheduling, margin and lead time without re-keying data between systems.
Yes. Machine building software rarely stands alone. We integrate with your CAD and PLM environment so that bills of materials and revisions from engineering flow through to procurement and assembly, and with your ERP or accounting package for purchase orders, hours, project costing and invoicing. Where systems offer an API or export format, we build the integration so that data is recorded once and remains reliable in one place. This prevents duplicate entry and version mismatches between drawing, bill of materials and shop floor.
Yes. A delivered machine often remains under the management of your service department for many years. The software keeps track of the installed base: per machine, the configuration, the revision delivered, the service history and the contract terms. Notifications and faults come in as tickets, are scheduled and resolved, and consumed parts and hours are recorded for invoicing or warranty. This turns service into a predictable revenue stream and gives you visibility of the condition of every machine in the field.
The bill of materials is the heart of any machine-building project. The software manages the BOM per machine and per revision, distinguishing between make parts, purchased parts and assemblies. When engineering makes a change, revision control records what changes and which open purchase or assembly orders it affects. Purchasing and the shop floor always work with the current version, and you can trace afterwards which revision was released. This prevents parts being ordered or fitted based on an outdated drawing.
We build for machine builders and special machine manufacturers who engineer to order, for systems integrators who combine machines and installations into a working whole, for equipment manufacturers with smaller runs and configurations, and for OEM suppliers who deliver modules and components within the supply chain. What these companies share is a project-driven process involving engineering, purchasing with lead times, assembly and long-running service. We tailor the software to each situation, around those processes and your existing CAD, PLM and ERP landscape.
