Supplier Portal Software.
A supplier portal is where your suppliers manage their relationship with your company on their own: they register, quote RFQs, confirm purchase orders, submit shipment notices and upload invoices against POs. With Sourced, your portal is live in 48 hours, connected to your ERP.

Supplier onboarding & scoring
The problem
Suppliers call to ask about PO status because they have nowhere to look. Invoices arrive by email in whatever format each vendor prefers, and a shipment's first sign of life is the truck at the dock. Then quarter-end comes and someone spends weeks reconciling statements line by line.
The solution
Each vendor gets a login to view POs, submit ASNs, upload invoices against specific purchase orders, and reconcile statements. AI validates every document on the way in, so your AP team handles the exceptions and lets the rest flow through.
Suppliers view full PO details with line items, quantities, and delivery schedules in real time
Invoice submission against PO with automatic three-way matching and AI discrepancy detection
Advance shipment notices (ASN) with carrier details and expected dates, so receiving knows what's coming
How it works.
View Purchase Orders
Suppliers log in and see every PO issued to them with full line-item detail: quantities, unit prices, delivery dates, and terms. The data syncs from your ERP, so what they see is what your system says.
Submit Advance Shipment Notice (ASN)
Before shipping, suppliers submit an ASN with full or partial quantities, carrier details, and expected arrival dates. AI validates the ASN against the PO and flags discrepancies before goods leave the warehouse.
Submit Invoice against PO
Suppliers upload invoices linked to specific POs. Sourced performs automatic three-way matching (PO → ASN → Invoice) and opens a Q&A thread for any discrepancy, so resolution happens in one place instead of an email chain.
Statement of Account (SOA) Reconciliation
Suppliers submit their statement of account and Sourced automatically reconciles it against your records. Multi-round back-and-forth is handled inside the portal until both parties agree on the balance.
Supplier portal features.
Individual vendor access
Each supplier gets their own secure login and sees only their POs, invoices, shipments, and communications. Role-based permissions for supplier admins and users.
AI-powered validation
AI checks every document submitted through the portal: quantities, prices, tax calculations, compliance rules. Errors get flagged before they reach your AP team.
Real-time notifications
Automatic alerts for new POs, approaching delivery dates, invoice approval status, payment confirmations, and Q&A responses. Suppliers stay informed without calling your team.
Supplier onboarding
Invite new vendors to the portal with a link. Configurable onboarding forms collect tax information, banking details, certifications, and compliance documents, all validated automatically.
Performance scorecards
Suppliers see their own numbers: on-time delivery, invoice accuracy, ASN compliance, quality scores. A vendor who can see their score tends to fix it.
ERP integration
Bi-directional sync with SAP, SAP Business One, Oracle, Dynamics 365, and Odoo. POs, invoices, ASNs, and payment status flow automatically between your ERP and the portal.
Supplier onboarding & approval
Suppliers register themselves: tax data, certificates and documents. The system validates and your team approves onboarding in one click.
Findable by your suppliers
Every portal is reachable from any browser, nothing to install: suppliers find it and operate from day one, no training required.
Frequently asked questions about supplier portal software.
What is supplier portal software?
Supplier portal software is a self-service platform where your vendors can view purchase orders, submit invoices, send advance shipment notices (ASNs), reconcile statements, and communicate with your procurement and AP teams, all from a single web interface. It replaces the back-and-forth of email-based processes.
What is an Advance Shipment Notice (ASN)?
An ASN is a document sent by a supplier before shipping goods. It details what is being shipped, quantities, carrier information, and expected arrival date. Sourced's portal lets suppliers submit ASNs digitally, linked to specific POs, so your receiving team knows exactly what to expect.
How does invoice submission against a PO work?
Suppliers select the PO they are invoicing against and upload their invoice. Sourced automatically performs three-way matching, comparing the invoice to the PO and the ASN (or goods receipt). If there are discrepancies in quantities, prices, or terms, a Q&A thread opens for resolution before the invoice enters your approval workflow.
Which ERPs does the supplier portal integrate with?
Sourced integrates bi-directionally with SAP S/4HANA, SAP Business One, Oracle, Microsoft Dynamics 365, and Odoo. Purchase orders sync from your ERP to the portal in real time, and approved invoices flow back automatically for payment processing.
How long does it take to set up the supplier portal?
Most clients have their portal live within 48 hours. We configure your PO sync, invoice matching rules, and supplier access. Onboarding your first suppliers typically happens the same week. No lengthy implementation projects required.
Do suppliers need to pay for portal access?
No. Supplier portal access is free for your vendors. They receive an invitation link, create their account, and start operating immediately. The cost of Sourced is covered by your organization's subscription.
How does a new supplier get onboarded?
The supplier receives an invitation (or finds your company's portal) and completes registration: tax data, documents and certificates. Your team reviews and approves. Minutes, not weeks of emails.
I'm a supplier, how do I access a client's portal?
If your client runs on Sourced, their supplier portal is reachable from the invitation link you received by email when you were onboarded or invited to quote. From there you can quote, confirm orders and upload invoices at no cost.
