Understanding the vendor onboarding process starts here
Let’s be honest: Vendor onboarding, also called vendor enablement, is not easy. You’re juggling hundreds of vendors who all work differently, trying to get them to actually change while keeping everyone’s data flowing correctly. Here’s what you need to know to make it work.
Vendor onboarding is difficult to manage yourself
The biggest challenge in vendor onboarding isn’t technology. It’s persuading vendors, suppliers and carriers to change.
Consider this:
You have 250 vendors to onboard to a new EDI requirement.
Some vendors will be ready to go, others will need more convincing and many will need guidance through the process.
Your vendors likely ask themselves: “Why should I have to change?” and “What’s in it for my business?”
Here’s what your team can expect:
750-1,200 attempts
to find the right contact via phone or email (3–5 attempts per trading partner)
2,500–3,000 communications
to gain commitment to the initiative (10–12 communications per trading partner)
175 trading partners (70%)
will have a question or objection regarding timing, technology or cost
100–150 trading partners (40–60%)
will need support in finding the right EDI solution
2,500–3,000 communications
to set up trading partners on requirements (10–12 communications per trading partner)
60 trading partners (25%)
will never have done EDI before and require training to understand the value
For many retailers, the only way to manage this complexity is with the right partner and a clear plan.
Frequently asked questions about vendor onboarding
What is vendor onboarding?
Vendor onboarding is the process by which retailers integrate a new vendor into their operations or change how they work with existing vendors. It includes steps like setting up items, registering the vendor in your systems and establishing an efficient order management process.
Why is vendor onboarding important?
An effective onboarding process helps vendors receive and fill orders correctly, ship on time and in full and provide the data needed for smooth business processes. This structured approach strengthens supplier collaboration and creates a foundation for mutual growth.
How does EDI fit into vendor onboarding?
EDI is often one of the requirements vendors must meet during onboarding, but it is only part of the overall process. Some vendors already have an EDI system in place that can be connected, while others may use a full-service option certified with the retailer. In both cases, SPS tests and certifies the data so it flows consistently into your systems.
Why is vendor onboarding so challenging for retailers?
Managing hundreds or thousands of vendors requires significant time and resources. Many vendors need guidance to understand requirements, and some may be new to data exchange, which makes onboarding complex without a proven approach.
How does SPS onboard so many vendors so fast?
SPS dedicates a team of consultants to each onboarding program and follows a proven campaign strategy perfected over 15 years. This human-led approach makes onboarding faster and more successful.
What happens if my supply chain requirements change?
Vendor onboarding is not a one-time event. SPS continues to support you and your vendors as your business needs evolve, keeping supplier collaboration strong and consistent.
What supply chain metrics can I expect to improve?
Retailers typically see gains in fill rates, order accuracy and shipment timeliness after following a structured onboarding process. Scorecarding and real-time analytics provide insights that allow you to work with vendors on performance improvements.
Does SPS work with all types of vendors?
Yes. Whether vendors are large or small, experienced with EDI or new to electronic trading, SPS provides clear guidance and support to help every vendor meet your requirements.

A roadmap for successful vendor onboarding
Onboarding vendors at scale requires a structured approach. These seven steps form the foundation of success.

Define your goals:
Set clear objectives for onboarding and align them with your organization’s broader business outcomes.
Segment your suppliers:
Organize vendors by factors such as volume, product line, region or season to prioritize onboarding efforts.
Determine fulfillment models:
Identify which fulfillment options (including ship-to-DC, drop-ship, cross-dock, import and ship-to-store) will be part of your program.
Define information to be shared:
Standardize the exchange of critical data, including inventory, orders, ship notices and invoices.
Staff accordingly:
Assign dedicated internal resources or engage an onboarding partner to manage communications and support.
Use a non-exclusive approach:
Provide vendors with flexibility to use their existing systems or a pre-certified EDI solution.
Ongoing change management:
Track performance with vendor scorecards and continuously improve collaboration.
