Full-service installation with no hidden costs
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.
For logic adjustments, we use Server Scripts (Python) to perform validations or calculations in the backend, and Client Scripts (JS) for dynamic UI behavior.
We hook into the document lifecycle (Before Save, On Submit). This allows us, for example, to automatically create external shipping orders upon order receipt.
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.
How we implement ERPNext development in practice.
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).
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.
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).
