Custom Vendor Portal Development Services
Connect external suppliers with internal procurement teams, automate purchase order tracking, eliminate invoice matching delays, and streamline RFQ bidding with a bespoke B2B Vendor Portal.
What is Vendor Portal Development?
Our custom vendor portal development service creates a secure external gateway for approved suppliers. It allows vendors to view and acknowledge issued purchase orders (POs), submit Advance Shipping Notices (ASN) with carrier tracking details, upload digital tax invoices, participate in Request for Quotation (RFQ) reverse auctions, and monitor invoice payment status.
Who Needs It: Manufacturing enterprises, retail supermarket networks, automotive component assemblers, construction promoters, and large commercial enterprises dealing with hundreds of external raw material and service suppliers.
Business Challenges Solved: Stops endless supplier phone calls asking "When will my bill be paid?", eliminates manual data entry of vendor invoices into accounts payable, prevents shipment delays through digital ASNs, and ensures transparent procurement bidding.
Why Custom Over Off-the-Shelf: Standard supplier portals in ERPs (SAP Ariba, Coupa) carry exorbitant supplier transaction charges and complex user interfaces that small vendors cannot navigate. A custom vendor portal from Arvis Digital provides a clean, intuitive interface tailored to your suppliers with zero per-transaction or per-vendor fees.

Frequently Asked Questions
Clear answers regarding customization, data ownership, integration capabilities, and deployment options for vendor portal development.
Can suppliers upload PDF invoices directly through the portal?
Yes. Suppliers can select the corresponding Purchase Order, upload their tax invoice PDF, and verify line items. The system automatically performs a three-way check against the PO and receiving notes (GRN).
How does the portal reduce supplier phone calls regarding payment status?
Suppliers have a dedicated "Invoice Status" screen showing real-time updates: Received, Under Verification, Approved by Accounts, and Scheduled for Payment with exact bank disbursement dates.
What is an Advance Shipping Notice (ASN) and why is it useful?
An ASN is a digital document submitted by the supplier when goods leave their factory. It specifies the transport truck number, driver contact, and exact carton counts. This enables your warehouse receiving team to prepare dock space and inspect shipments faster.
How does the online RFQ bidding module work?
Your procurement team publishes a Request for Quotation (RFQ) with technical drawings and required delivery dates. Invited vendors submit their best unit prices and lead times before the tender deadline, allowing side-by-side comparison.
Is it easy for small vendors to use without technical training?
Yes. We design vendor portals with intuitive, clean interfaces that require zero training. Suppliers can log in from any web browser or smartphone, view POs, and submit invoices in seconds.
Do suppliers have to pay any subscription fee to access the portal?
No. Unlike third-party platforms like SAP Ariba that charge suppliers transaction fees, your custom vendor portal is completely free for all your suppliers to access.
