Custom Isah integration development
Appfront builds custom Isah integrations for the manufacturing industry. Through the Isah API and web services, we connect your ERP with your webshop, MES, PLM, BI dashboards or in-house application, with orders, items, production and stock synchronised in real time. That way your shop floor works with the same data as sales and purchasing, and you keep control over lead times, capacity and margin.
What is an Isah integration?
Isah is a Dutch ERP package developed specifically for the manufacturing industry. It supports the full process of project- and order-driven production: costing and quotes, job preparation, production planning, stock and purchasing, and post-calculation and service. This makes Isah the heart of the application landscape at machine builders, metal and plastics processors and suppliers.
In practice, a custom integration means webshop or customer orders automatically landing in Isah as sales orders, item and bill-of-materials data syncing with PLM or CAD, production progress flowing back from machines on the shop floor, and BI dashboards drawing on the same ERP data. Isah remains the central source of truth, and adjacent systems work with exactly the same data.
Appfront builds in line with Isah's connectivity and integrations and the OWASP ASVS security standard. We tailor data flows, synchronisation and error handling to your actual production process, so the integration grows with your business and stays reliable even at peak volumes.
ERP for the manufacturing industry
Costing, quotes, job preparation, production planning, stock, purchasing and post-calculation in one package, tailored to project- and order-driven production in machine building, metal and plastics.
Insight into production
Lead times, capacity, progress and margin per order or project become visible. The shop floor, planning and the office work with the same data, so decisions rest on current figures rather than scattered exports.
Central to your landscape
Isah remains the single source of truth while your webshop, MES, PLM, BI and accounting connect via the API and web services. No duplicate data entry and no isolated silos: one set of data flows through the entire chain.
Our development process for Isah integrations
We work to a proven methodology that removes uncertainty early and delivers a stable integration. From an initial analysis of your production process, data flows and Isah environment through to go-live and ongoing management, every step aims at an integration your team can understand and trust.
We map out which processes you want to connect (orders, production, stock or post-calculation), which systems are involved, which Isah endpoints are relevant, and whether real-time or periodic synchronisation suits best.
We design the integration architecture, select the right authentication using API credentials, and define an error-handling strategy.
Implementation with automated tests, structured logging and monitoring. You see working builds along the way.
Controlled go-live with data validation and a safety net, followed by ongoing management and further development.
What an Isah integration delivers in practice
Every Isah integration is set up specifically for your type of production, data flows and adjacent systems. Below are the features we most often deliver for manufacturers who use Isah as their central ERP.
Webshop and e-commerce orders
Orders from your webshop or customer portal are automatically created as sales orders in Isah, including items, quantities and customer details. Stock and lead time information flows back to the webshop, so customers always see current availability.
Production and capacity planning
Production orders, work orders and scheduling kept in sync with your planning board or MES. Progress, booked hours and utilisation feed back into Isah, so planning and the shop floor are steered by the same up-to-date picture.
Stock & purchasing
Stock levels, warehouse locations and purchase orders linked to suppliers, WMS or automated warehouses. Purchasing recommendations and goods receipt follow the actual demand from production and sales.
MES and machine integration
Machines for laser cutting, turning, milling or bending connected to Isah via an API for real-time integration or XML for periodic synchronisation. Work orders go to the machine; confirmations and machine data flow back into the ERP.
BI dashboards (Power BI)
Isah data made available to Power BI or another BI platform for dashboards on lead time, margin, utilisation and order book. Management and production planning steer on clear KPIs instead of scattered reports.
Customer portal and service
A customer portal where buyers view order and production status, lead times and service notifications, fed by the same Isah data. Service and maintenance orders feed back, so the entire aftercare stays traceable.
Typical use cases in practice
An Isah integration looks different for every manufacturer. We see a number of patterns recurring, and for each one we have a working setup with attention to data flows, synchronisation and the right error handling.
Machine building
Machine and equipment builders with engineer-to-order production who manage costing, bills of materials, production preparation and planning in Isah. An integration with CAD/PLM keeps items and bills of materials in sync; progress from the shop floor flows back in real time. See also our API integrations.
Metalworking
Metal fabricators and sheet metal companies doing laser cutting, press braking, turning and milling. Work orders go to the machines on the shop floor; confirmations, booked hours and material consumption flow back into Isah for reliable post-calculation per order.
Plastics processing
Plastics and injection moulding companies producing series with moulds, tooling and a range of raw materials. Stock, purchasing and production planning run through Isah, while machine data and quality registration feed post-calculation and margin per order.
Project and order-driven supply
Suppliers that produce to customer order or project and want to open up their supply chain. Webshop or EDI orders come in, production and purchasing run through Isah, and order and lead time information feeds back to customers and the customer portal.
Technology we use
We build Isah integrations using the Isah API and web services, combined with the backend stack that suits you. The precise choice depends on your systems and synchronisation needs, so that your own team can manage or further develop the implementation.
Why Appfront for your Isah integration?
Appfront has extensive experience building API integrations for a wide range of organisations in the Netherlands, including manufacturers. We always start with a thorough analysis of your existing systems and processes. An integration should not only work technically, but also add practical value to your production process.
For every integration, we write clear documentation and make sure your own team, or any future supplier, can understand and manage it. No black box, just transparent code and clear agreements on monitoring, alerting and maintenance.
You work with a dedicated point of contact who understands both the technical and the functional side. This keeps communication short, prevents misunderstandings and speeds up decisions when choices need to be made during development.

Security and privacy in Isah integrations
Order, production and customer data is business-sensitive and often contains personal data. Appfront builds to the OWASP ASVS security standard. Among other things, that means API credentials in secure vaults, encrypted connections, scoped permissions per integration and regular audits of the data flows between Isah and your other systems.
We document the data flows, endpoints and synchronisation so that your record of processing activities is complete and you can demonstrate compliance with the GDPR. Logging and monitoring from day one make every exchange between the shop floor, the office and connected systems traceable, even when something goes wrong.

Frequently asked questions about Isah integrations
Answers to the questions we are asked most often about Isah integrations.
An Isah integration is a technical link between the Isah ERP and another system, such as your webshop, MES, PLM, BI dashboard, accounting package or your own application. Data on orders, items, production, inventory and costings is exchanged via the Isah API and web services. This can happen in real time through the API or periodically through XML synchronisation. An integration can be simple (webshop orders automatically created as sales orders in Isah) or extensive (production planning, machine data and post-calculation running across several systems).
Isah is a Dutch ERP package that is strong for manufacturers with project- and order-driven production: machine building, metal and plastics processing, subcontracting, and engineer-to-order or make-to-order. It supports costing, quotes, job preparation, production planning, stock, purchasing and post-calculation in one package. For pure retail or stock-based ERP, or a broad enterprise landscape, other packages may be a better fit; we are happy to look with you at whether Isah best suits your production process.
A simple integration, for example webshop orders automatically landing as sales orders in Isah, can go live relatively quickly. More extensive scenarios involving production and capacity planning, MES or machine integration, BI dashboards, and feedback of progress and post-calculation usually take longer. After an intake meeting in which we map out your data flows and systems, we provide a realistic estimate.
We work with the Isah API and web services, combined with the backend stack that suits you: Node.js, Python, .NET or PHP. Authentication is handled via API credentials. For the exchange we use the endpoints for orders, items, production, inventory and costings and, where relevant, XML synchronisation for periodic exchange. For BI reporting we connect Isah data to Power BI; machines on the shop floor are connected via MES/IoT protocols.
Costs depend on the complexity of the data flows, the number of systems to integrate, the required synchronisation frequency and the amount of custom business logic. Ongoing management, monitoring and support also affect the total investment. We always provide a clear quote following a no-obligation analysis of your situation and your existing Isah environment.
Yes. Production, order and customer data is business-sensitive and often contains personal data. Appfront builds to the OWASP ASVS: API credentials in secure vaults, encrypted connections, scoped permissions per integration and strictly separated access. We document the data flows so your record of processing activities stays complete and you can demonstrably comply with the GDPR. Logging and monitoring from day one make every exchange traceable.
Yes. Appfront regularly takes over existing integrations, even if they were originally set up by another party or the vendor. We review the API integrations, data flows, error handling and synchronisation, document the current setup and propose improvements. From that point on, we can handle adjustments, extensions and monitoring, including timely rotation of API credentials.
Isah is a good fit for manufacturers with project- and order-driven production: machine builders, metal and plastics processors, equipment makers and suppliers working engineer-to-order or make-to-order. Typical integrations include webshop orders to the ERP, production and capacity planning, stock and purchasing, MES and machine data from the shop floor, BI dashboards for lead time, margin and utilisation, and a customer portal for order and service status. Less suited to pure retail or a broad enterprise landscape; there we will work with you to see whether another package is a better match.
