ERPNext Development & Integration
ERPNext is based on Frappe, a brilliant metadata-driven framework. We use this for quick adjustments but don't shy away from developing complex business apps as standalone Frappe apps.
Server Scripts & Client Scripts
For logic adjustments, we use Server Scripts (Python) to perform validations or calculations in the backend, and Client Scripts (JS) for dynamic UI behavior.
Document Hooks
We hook into the document lifecycle (Before Save, On Submit). This allows us, for example, to automatically create external shipping orders upon order receipt.
Custom Frappe Apps
We strictly separate your custom code from the core. We package your adjustments into a separate app installed alongside ERPNext. This guarantees stress-free updates.
Concrete Use Cases
How we implement ERPNext development in practice.
Industry-Specific DocTypes
A laboratory needs data fields (sample ID, temperature) that do not exist in any standard ERP.
Creation of Custom DocTypes incl. relations and logic. These behave like native ERP objects (searchable, filterable, API-ready).
External API Integration
Data from an external fleet management system must be available in ERPNext for billing.
A scheduled job (Python) regularly polls the external API, maps the data, and automatically creates 'Delivery Trips' in ERPNext.
Jinja Print Formats
Delivery notes must contain barcodes for warehouse scanners and have a specific layout.
Development of HTML/Jinja templates that dynamically generate barcodes and conditionally format data (e.g., hazardous material warnings).

“I recently worked with Timo and the WZ-IT team, and honestly, it turned out to be one of the best tech decisions I have made for my business. Right from the start, Timo took the time to walk me through every step in a simple and calm way. No matter how many questions I had, he never rushed me. The results speak for themselves. With WZ-IT, we reduced our monthly expenses from $1,300 down to $250. This was a huge win for us.”

“WZ-IT provided very competent support in implementing our server and virtualization infrastructure. As part of the project, a Proxmox-based virtualization environment was set up along with a virtual machine for our application systems. Additionally, a structured backup concept was implemented. A particular focus was on security: the setup of a VPN tunnel and the clean implementation of encryption and access concepts were professionally executed. The structured consulting as well as the reliable and swift implementation deserve special mention. We are very satisfied with the services provided and are happy to recommend WZ-IT.”

“We have had very good experiences with Mr. Wevelsiep and WZ-IT. The consultation was professional, clearly understandable, and at fair prices. The team not only implemented our requirements but also thought along and proactively. Instead of just processing individual tasks, they provided us with well-founded explanations that strengthened our own understanding. WZ-IT took a lot of pressure off us with their structured approach - that was exactly what we needed and is the reason why we keep coming back. (translated)”

“Timo and Robin from WZ-IT set up a RocketChat server for us - and I couldn't be more satisfied! From the initial consultation to the final implementation, everything was absolutely professional, efficient, and to my complete satisfaction. I particularly appreciate the clear communication, transparent pricing, and the comprehensive expertise that both bring to the table. Even after the setup, they take care of the maintenance, which frees up my time enormously and allows me to focus on other important areas of my business - with the good feeling that our IT is in the best hands. I can recommend WZ-IT without reservation and look forward to continuing our collaboration! (translated)”
