Procurement & Sourcing Solutions
Pass-Through Purchasing & Tail Spend Management
A third-party buying service for the purchases your team shouldn't have to onboard a vendor for. We act as your buyer of record for one-off and infrequent suppliers, manage tail spend and run sourcing as an extension of your team—senior-level execution, not a junior bench.
As organizations scale, managing indirect and third-party spend—complex supplier networks, competitive contract terms, and niche vendor onboarding—consumes internal resources that should be focused on the work only your team can do. We take on that operational load, running sourcing, vendor governance, and channel management as an extension of your organization, not a black-box vendor relationship.
Whether you need targeted sourcing execution for a single spend category or ongoing management of your vendor channel, engagements are scoped around your spend profile, internal capacity, and financial workflow—not a one-size-fits-all arrangement.
Service Models
Built Around Your Spend Profile
Three ways to engage, depending on how much of the process you want us to own.
01
Strategic Sourcing & Category Management
Best for high-impact spend categoriesWe partner with your leadership on market intelligence, RFX processes, vendor evaluation, and contract negotiation for the categories that move your P&L—then hand you a blueprint your team can execute on.
02
Managed Procurement & Outsourced Tail Spend Management
Best for un-contracted, high-volume, indirect spendWe manage your non-strategic, high-volume, and maverick spend—supplier onboarding and requisition processing—without adding every one-off vendor to your internal systems. It's a practical alternative to a dedicated procurement hire: your team gets full spend visibility and an audit trail, without the onboarding burden of a growing vendor list.
03
Pass-Through Purchasing & Principal Reseller Services
Best for consolidating vendor sprawl and subcontractor billingWe serve as the principal buyer or merchant of record—handling contracting, billing liability, and vendor pass-through so a fragmented supplier base becomes one rationalized, predictable invoicing relationship.

Common Questions
Pass-Through Purchasing & Tail Spend: Questions We Hear
What is pass-through purchasing?
We buy on your behalf as the principal buyer, or merchant of record. You issue one purchase order to LeVasseur Consultants; we contract with, pay and manage the end supplier. The supplier never has to be set up in your systems, and you receive one itemized invoice with supplier costs and our service fee shown separately.
When should a company use a third-party buying service?
When a purchase is one-time or infrequent, when setting up a new vendor would take longer than the purchase itself, or when dozens of small suppliers are cluttering your vendor master and accounts payable. For organizations in tightly regulated industries, it also means low-risk, one-time suppliers do not have to go through a qualification process designed for critical suppliers, while your purchasing controls stay in place.
How can we manage tail spend without hiring full-time procurement staff?
We take on your non-strategic, high-volume and maverick spend: requisitions and supplier onboarding, with defined spend thresholds, a clear record of every purchase and periodic spend reporting. Your team keeps full spend visibility without adding headcount.
Can you buy from suppliers that aren't on our approved supplier list?
Yes. We qualify and manage one-time or infrequent suppliers directly, so your internal systems and preferred-vendor list stay clean, current and easy to govern.
Who do you work with?
