Supplier Portal Software.
Give your suppliers a self-service portal to view purchase orders, submit invoices, send advance shipment notices, and reconcile accounts — with AI validating every step.
The problem
Your suppliers call and email constantly asking for PO status. Invoices arrive by email in different formats with frequent errors. You have no visibility into shipments until they show up at the dock. Statement reconciliation is a manual, multi-week process that delays payments and strains relationships.
The solution
Sourced's supplier portal gives each vendor their own login to view POs, submit ASNs, upload invoices against specific purchase orders, and reconcile statements — all with AI validating data at every step. Your AP team stops chasing paper and starts managing by exception.
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 tracking and expected delivery dates for full supply chain visibility
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. Data syncs in real time from your ERP so there are no outdated spreadsheets or missing information.
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 discrepancies — no more email chains or phone calls.
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 validates every document submitted through the portal — checking quantities, prices, tax calculations, and compliance rules. Errors are 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 — validated automatically.
Performance scorecards
Suppliers see their own performance metrics — on-time delivery rate, invoice accuracy, ASN compliance, and quality scores. Transparency drives continuous improvement.
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.
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 eliminates 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.
