How to Build a Vendor Management System for ERPNext

Royalsmb — Fri, 03 Apr 2026 17:28:14 +0000

ERPNext gives you Suppliers, Purchase Invoices, and Payment Entries out of the box. But if you manage dozens of vendors, you quickly run into gaps. There is no way to track contract expiry dates, monitor SLA compliance, manage vendor documents with renewal alerts, or run a structured onboarding process.

We built a Vendor Management app that fills these gaps. Everything links back to your existing Supplier and Purchase Invoice data so you do not maintain anything in two places.

What You Get

The app adds six features to your ERPNext:

Vendor Contracts with milestones, amendments, auto-renewal tracking, and expiry notifications. The system alerts contract owners before a contract expires so nothing slips through the cracks.

Vendor SLA Monitoring to set performance targets and track actual measurements. Define a 99.9% uptime target or a 4-hour response time and the system tells you whether each period was met, partially met, or missed.

Vendor Document Management for storing insurance certificates, tax IDs, business licenses, and compliance reports with automatic expiry tracking.

Vendor Onboarding with a checklist workflow that starts automatically when you add a new Supplier. No manual setup needed.

Vendor Ratings across quality, delivery, communication, and price on a 5-star scale.

Invoice Dispute Tracking linked directly to your ERPNext Purchase Invoices, with a structured workflow from Open to Resolved to Closed.

Your Vendor Hub

Once installed, the app gets its own workspace in the sidebar. The shortcut counters update in real-time so you can spot expiring contracts and open disputes at a glance.

Contract Lifecycle Management

Create a contract, link it to a Supplier, set the dates, and submit. The system takes it from there. It moves contracts from Active to Expiring Soon to Expired automatically, and sends email alerts to the contract owner when the expiry window opens.

The milestones table tracks deliverables, payments, and review dates. The amendments table keeps a record of any changes made after signing.

SLA Compliance at a Glance

Define your SLA targets and add measurements as they come in. The system calculates compliance percentages and flags which periods fell short.

Automated Onboarding

Every time you create a new Supplier in ERPNext, the app generates an onboarding record with a default checklist covering tax registration, bank details, NDA, and compliance. Your team works through the checklist and submits it for approval. When approved, the vendor's risk tier is pushed to the Supplier record automatically.

Dispute Resolution

Track billing disagreements with a structured workflow. Link the dispute to a Purchase Invoice, assign it to a team member, and move it through the resolution process using action buttons.

Reports

Six built-in reports pull from both your vendor data and existing ERPNext transactions. The Vendor Spend Report queries submitted Purchase Invoices. The Contract Expiry Report sorts by urgency. SLA Compliance, Vendor Ratings, Document Expiry, and Onboarding Status reports round out the analytics.

Background Automation

The app checks all contracts, documents, and SLAs for expiry every day and updates statuses automatically. Supplier spend is recalculated weekly. When a Purchase Invoice is submitted, the supplier's year-to-date spend updates immediately.

Compatibility

The app works on ERPNext v15 and v16. It comes with a full user manual, test data setup, and three permission roles (Vendor Manager, Vendor User, Vendor Viewer) configured out of the box.
