Ask the program manager how many workers are in the program, and you get a number. Ask finance how many people were paid for work last quarter, and you often get a bigger one. The difference is made up of shadow contingent workers: people doing real work for your company through a marketing lead's freelance budget, an international team's local arrangements, or a statement of work that cleared legal without ever touching procurement. Nobody decided to leave them outside the program. A deadline was close, and because the formal route was slower, the work started anyway.
How Shadow Contingent Workers Get Past Your Program
A hiring manager with a launch date and no designer has two options. The approved route means a requisition, a supplier submission, and an onboarding queue. A card payment and a one-page agreement take an afternoon. Repeat that choice across every division, and the program ends up governing only the hires that had time to wait.
In a 2026 industry survey, half of the companies said they engage more than a quarter of their independent talent outside the formal program, and a third said more than half. The sample was small, so read the percentages as directional. The routes were consistent, though: international teams and marketing were each named by half of the companies as the main way it happens. Both have an ordinary explanation. An overseas team usually hires locally to keep pace with its own market, and marketing tends to buy specialist help campaign by campaign from a budget the program office never sees.
How Much Off-Program Work Is Normal
Staffing Industry Analysts asked buyers to guess. In its 2025 Workforce Solutions Buyer Survey, 55% of companies estimated that up to 20% of their contingent spend falls outside the authorized program, and the median answer landed between 11% and 20%. Another 9% put it above half. High performers reported less, with half of them estimating 10% or less.
Because the question asked for a guess, those figures show how much people believe they can see. The 2026 survey adds a detail worth sitting with: half of the companies said they have only limited visibility into the work happening outside their program, and half said they aren't concerned about it. The people running the program may be the last to learn what it leaves out.
Where to Look for Shadow Contingent Workers
Start where the money moves. Off-program spend tends to show up first in accounts payable, as invoices and card charges coded to consulting or marketing instead of to a labor category. Pull a quarter of payments made to individuals and very small companies, then compare the names against your program's worker list. Every name that doesn't match is a question for the budget owner.
Then ask the people who sign. Project owners in marketing and product, along with the heads of your international offices, know which specialists they brought in, and a short conversation will often turn up more than a report does. Legal belongs on the list too, since a statement of work that was signed there without a procurement touchpoint may never reach a program dashboard.
If a name turns up in your identity system but nowhere in the program, that's another lead. A person with a company email account and shared-drive access has been working somewhere, and your IT team can list the accounts that have no matching record in the program or the HRIS.
What an Unrecorded Worker Costs When Someone Asks
When the IRS decides whether someone is an employee or an independent contractor, it looks at three kinds of evidence: behavioral control, financial control, and the relationship of the parties. The agency says to weigh all the evidence of control and independence, and a written agreement counts as one fact among several.
A shadow worker usually arrives with a short agreement and an invoice, and little else on file. Suppose that person has kept set hours on your team for eight months using your tools. The agreement then describes an arrangement the facts may no longer match, and the Department of Labor puts the responsibility for that call on the employer. It also notes that misclassified workers may not receive the minimum wage and overtime pay they are owed under the Fair Labor Standards Act.
Paperwork is the other exposure. In the 2026 survey, half of the companies could not produce an audit-ready file for any worker, so a worker nobody recorded has no file to start from.
Bring Shadow Contingent Workers Under One Employer
The first instinct after a discovery like this is to tighten approvals. Tighter approvals add more delay, though, and delay is what sent managers around the program to begin with. A better fix gives the manager a route that is quicker than a card payment.
An Employer of Record (EOR) can be that route. When the EOR becomes the legal employer, an off-program engagement moves onto the same payroll, tax handling, classification review, and onboarding standard as every other worker, in all 50 states. With FoxHire, workers your managers have already found can start their paperwork within hours of a complete submission, which puts the formal path close to the speed of the informal one. Our post on growing your EOR before you add a VMS covers the order for moving workers across. Anyone working outside the United States sits beyond what a U.S.-focused EOR covers, so sort your list by location before deciding who moves over.
Run the accounts payable comparison first. It takes an afternoon, and it will tell you whether you're looking at a handful of names or a second program.

FAQs
Find answers to common questions about our services and the contingent workforce management.
What are shadow contingent workers?
They are people who do work for a company outside its formal contingent workforce program, through direct freelance arrangements, card payments, or statements of work that skip procurement. They often have no entry in the program's worker list, which is why classification and compliance checks miss them.
How common is off-program contingent spend?
In Staffing Industry Analysts' 2025 buyer survey, 55% of companies estimated that up to 20% of contingent spend sits outside the authorized program, and the median answer was between 11% and 20%. These were estimates from the buyers, not audited figures.
How do you find contingent workers outside your program?
Compare accounts payable payments to individuals and small vendors against your program's worker list, ask project owners and international office heads who they have brought in, and check your identity system for accounts with no matching worker record. Each method catches people the others miss.
Is hiring a freelancer directly a misclassification risk?
It can be. The IRS looks at behavioral control, financial control, and the relationship of the parties, and a written agreement is one fact among several. The answer depends on how the work happens day to day.
Can an EOR take over workers a company already uses?
An EOR can employ workers a company has already found, including people who have been working through direct agreements. For workers in the United States, the EOR becomes the legal employer and handles payroll, taxes, and onboarding from that point.
