New supplier onboarding or vendor onboarding can sometimes be a slow starter. Capturing payment information and tax details while getting new vendors up to speed on your systems, policies, and procedures can cause delays in payment processing, holding up your day-to-day business operations in ways you would likely prefer to avoid.

This article defines what supplier onboarding means and describes how to improve your process for supplier onboarding with automation.

What is Supplier Onboarding (a.k.a. Vendor Onboarding)?

Supplier (or vendor) onboarding is the process of collecting necessary information from suppliers used for procurement to set them up as approved sellers with your company. This process aims to help you do business together, buy goods and services and make payments to vendors.

What is the true cost of vendor onboarding?

Having a dedicated person on staff to walk new vendors and suppliers through your onboarding process is certainly one solution, but in today’s fast-paced business climate, do you have the time or the resources to allocate to this task?

When onboarding a new supplier, the flurry of emails and the ensuing questions are something that many companies see as an unavoidable cost of doing business. In an enterprise scenario, delays such as these can cost thousands of dollars. Small businesses also stand to lose, as the cash flow they depend on can be stuck in limbo while systems are put into place and the inevitable kinks get worked out.

How do businesses automate supplier onboarding?

Self-service supplier portals may be part of a customer’s add-on AP automation software to streamline workflows and manage and pay vendors in its supply chain. The best real-time supplier portals provide self-service supplier onboarding, followed by supplier relationship status and monitoring, including order delivery and payment status and reminders for renewals or updates required. 

A self-serve supplier/vendor portal is a viable solution that provides value for all stakeholders. It offers your vendors and your in-house accounting team a simple, easy-to-use web-based interface that they can access at any time, from anywhere.

A supplier/vendor portal that offers dynamic web forms that connect to your AP/AR software is even more valuable. It eliminates several steps in the onboarding process, creating a seamless experience for your vendors and providing your finance team with a more streamlined way to acquire the needed information.

Vendor onboarding portals are designed to let you collect the information and onboarding documents you’ll need from vendors, including their supplier payment process information. 

With process automation, vendor master data must only be entered once, and your system will be automatically updated with the new information. Guided self-service and automated supplier onboarding help you save time and money, as your staff can refocus their efforts to higher-value tasks.

How to develop an effective supplier onboarding process

Analyze and flowchart supplier onboarding workflows in your business. Consider developing a vendor onboarding checklist or questionnaire to ensure all related business processes are covered. You may establish more extensive processes for strategic suppliers with significant potential impacts on your business if certain adverse events occur.  

Supplier onboarding processes and supplier management workflows are:

  • Getting vendor contact information 
  • Remittance information
  • Other supplier information
  • W-9 or W-8BEN tax forms for preparing 1099 forms
  • Validation of vendor data for fraud prevention
  • Due diligence
  • Risk assessment of prospective suppliers
  • Approval process 
  • Sourcing
  • Purchase order
  • Items
  • Pricing 
  • Quantities
  • Payment terms 
  • Order delivery
  • Vendor invoicing
  • Payment status with notifications
  • Vendor management metrics. 

In a typical vendor onboarding process, multiple departments must be involved, each with its own data requirements to support day-to-day activities. To be effective, you need a solution to facilitate collaboration and enable a timely response when needed. From international tax issues to legal agreements, purchasing, supply chain, logistics, fulfillment, accounting, and more, documents and data must be accessible to the appropriate people when they need it most.

Having a supplier portal with process management available simplifies these activities, giving stakeholders on both sides of the business relationship a centralized, barrier-free solution that meets business needs, reduces errors and payment and supplier risk, and provides value from end to end. The supplier portal enhances vendor relationships.

The most apparent advantage of a vendor portal is that the vendor master data is centralized, along with invoicing, order, and payment history. This eliminates potential data silos, lifting barriers and enabling teamwork across a global landscape. 

The supplier portal can be used beyond onboarding for global supplier management throughout the supplier relationship lifecycle. The automated portal can be used for updates and ongoing risk assessment monitoring as part of your company’s risk management program. 

As it relates to your accounts-payable and accounts-receivable software and processes, this translates to a more streamlined workflow that is labor-sparing and dynamic. It provides financial metrics in real-time, offering dependable business intelligence and affording your decision-makers the ability to move forward confidently. Taking advantage of opportunities when they arise is the key to growth. The faster and more efficiently you can get your new vendors on board, the more such opportunities will become available.

Strategic vendor management is the key to ongoing success

In many industries, strategic supplier information management is the foundation that supports growth and innovation. However, effective communication in the enterprise is often impeded by data silos caused by multiple teams in many locations, some of whom may not use the same systems to collect and leverage data.

Takeaway – Supplier onboarding

Supplier onboarding is a process for implementing new supplier relationships, getting supplier data, communications, centralized documents, and status in combination with integrated vendor master and ERP software databases. Online software platforms like self-service supplier portals and AP automation software make vendor onboarding and two-way supply chain management more efficient and less time-consuming.
