Hello, Team Velora has been running for 3 years. I am Rahul Singh, and our expert team can implement server-side validations in ERPNext to ensure Pick Lists, Delivery Notes, and Sales Invoices never exceed the quantities confirmed on a Sales Order. We will provide clear, customized error messages, fully tested scripts without core edits, and instructions for deployment across environments. Please come to the chat box to discuss the project further.

Hello, I’m Malix Azis, an ERPNext developer with hands-on experience enforcing business rules cleanly inside the Sales workflow without touching core code ✨ I’ve implemented server-side and client-side validations that span Sales Orders, Pick Lists, Delivery Notes, and Sales Invoices, ensuring quantity integrity stays consistent no matter which screen or role a user operates from ⚙️ For your requirement, I can add logic that checks cumulative quantities against the linked Sales Order balance and automatically blocks over-picking, over-delivery, or over-invoicing while still allowing valid quantities to proceed ⭐ The validation will live at the Sales layer using hooks or scripts, so it remains reliable across Stock and Invoicing flows ✨ I’ll also implement friendly, precise feedback messages that clearly mention the item code and remaining allowable quantity, either using your template or proposing clean, user-friendly wording ⚙️ You’ll receive clear placement and migration instructions plus a concise test plan demonstrating all three documents behaving correctly under real scenarios ⭐ One clarification before coding: should returns or amendments to Sales Orders dynamically recalculate the allowable balance for existing downstream documents? ✨ Thanks for the opportunity, I look forward to tightening this workflow for you—have a great day!

I’m a systems developer majored in ERPNext/Frappe with experience enforcing cross-document validations and tightening core sales workflows without touching the framework core. I’m comfortable implementing clean server-side or client-side logic that stays consistent across Stock and Sales transactions. I can discuss approach, placement, and testing details directly on chat.

Hi, I can tighten your ERPNext Sales workflow so users cannot pick, deliver, or invoice more than what is confirmed on the Sales Order, with clear and friendly validation messages. My approach is to implement server-side validation tied to the Sales layer, checking cumulative quantities against the linked Sales Order on Pick List, Delivery Note, and Sales Invoice. The logic will run automatically regardless of whether users work from Stock or Invoicing, without any core edits. Let’s have a quick chat and discuss further. Best Regards, Usama

Hi, I’m a Frappe/ERPNext developer with 2 years of experience. I’ve worked on a real ERPNext project where I managed an Asset Management system for street lights. In that system: We had projects based on areas Each area had multiple street lights mapped Workers could maintain and repair the street lights The public could open a free public page where street lights were shown using coordinates/location People could raise complaints using a form (with details + image upload) In this project, I worked on: ✅ Server Scripts & Client Scripts ✅ Custom APIs ✅ Custom analytics/report pages ✅ Public HTML pages and public complaint forms I believe this experience makes me a good fit to complete your task properly and on time.

I can implement a clean ERPNext validation to ensure no user can pick, deliver, or invoice more than the confirmed Sales Order quantity. I will provide server-side scripts, clear instructions, and a test plan with friendly error messages for each item.

I will implement a robust Server-Side validation across Pick Lists, Delivery Notes, and Sales Invoices to enforce strict Sales Order limits. Using Python hooks ensures the logic remains consistent across Stock and Accounting modules. I’ll develop a unified check that calculates real-time balances and triggers personalized, item-specific warnings instead of generic errors. You’ll receive the scripts, a portable JSON for easy environment migration, and a comprehensive test matrix covering all three document types for sign-off.
