VMS Technology
Staffing Vendor Management System Services
Selection, configuration, integration, and day-to-day administration of the platform that becomes your system of record for contract labor.
A staffing vendor management system is the software that holds your requisitions, candidates, assignments, timesheets, and invoices in one place and enforces the approval rules around them. Viltis helps life sciences organizations choose, configure, integrate, and administer that platform. The technology is rarely the reason a program fails. Configuration is. A VMS set up to mirror an unstructured process gives you well-organized records of the same problems, which is why we start with the workflow and come to the software second.
Overview
Selection: choosing against your requirements, not a feature list
Vendor demonstrations look similar because they are built to. We help you write requirements that separate one platform from another: how it handles SOW milestone billing, whether approval chains can vary by cost center, what the integration surface looks like against your HRIS and ERP, how master data is structured, and what reporting you can build without buying vendor services hours.
We support the scoring model, reference calls, and commercial evaluation. We are also willing to conclude that your existing platform is fine and the problem is configuration or adoption.
Overview
Configuration: where programs are won or lost
Configuration decisions made in the first six weeks determine what you can report on for the next five years. We design those structures deliberately instead of taking the defaults.
Job category and labor taxonomy that supports rate benchmarking and spend reporting later
Rate card structure, including markup versus pay-rate models and geographic differentials
Approval workflows mapped to your real delegation of authority, including cost center and threshold routing
Intake forms that capture the compliance attributes regulated work requires, such as GxP impact and system access needs
Assignment lifecycle events (extension, conversion, early termination) modeled so reporting stays accurate
Supplier onboarding, insurance certificate tracking, and document expiry rules
Overview
Integration with the systems you already run
A VMS that does not talk to anything creates a second source of workforce truth. We scope and coordinate the integrations that keep it authoritative: worker and cost center data from the HRIS, purchase order and invoice flow to the ERP or accounts payable system, identity provisioning and deprovisioning tied to assignment dates, and learning system status where training gates access.
Integration scope is one of the most common causes of implementation overrun, so we prioritize by what the program needs on day one versus what can follow in a later phase.
Overview
Adoption: the part most implementations underfund
Hiring managers abandon a system that is slower than emailing a recruiter they trust. So we treat adoption as a design constraint: less friction at intake, defaults wherever a default is safe, and visible status after submission instead of a black box.
That is paired with role-specific enablement for managers, approvers, suppliers, and program administrators, plus post-launch monitoring of off-system hiring so leakage is caught while it is still correctable.
Overview
Ongoing administration
Platforms drift. New cost centers appear, approval thresholds change, suppliers are added and retired, rate cards need refresh, and vendor releases introduce features worth adopting. We provide ongoing administration so configuration keeps pace with the business instead of being revisited during the next audit.
Benefits
What a well-configured VMS gives you
One system of record
Requisitions, assignments, time, and invoices live together, so workforce reporting no longer requires stitching together supplier spreadsheets.
Controls enforced at the point of action
Rate limits, approval thresholds, and required onboarding steps are enforced by the workflow rather than discovered during a compliance review.
Reporting you can build yourself
A deliberate data taxonomy means your team can answer new questions without a services engagement every time leadership asks something different.
Clean assignment lifecycle data
Extensions, conversions, and terminations are captured as events, which keeps tenure tracking and access deprovisioning accurate.
Supplier self-service
Suppliers submit candidates, maintain documents, and invoice within the platform, which takes the coordination out of email and its version-control problems with it.
Adoption that holds after launch
Low-friction intake and visible status keep hiring managers inside the system, which is the only way program data stays complete.
FAQ
Vendor management system FAQs
Do we need a VMS if our contingent population is small?
Not always. Below a certain volume, a well-run process with disciplined reporting can be adequate, and platform cost may outweigh the benefit. We will say so if that is the case, and revisit when volume, site count, or audit exposure changes the calculation.
Can you work with the VMS we already own?
Yes. A significant share of our work is reconfiguring or re-implementing platforms that were deployed quickly and never revisited. Reconfiguration is usually faster and less disruptive than replacement.
What is the difference between a VMS and an applicant tracking system?
An applicant tracking system manages your permanent hiring funnel. A VMS manages non-employee engagements after the requisition is approved: supplier distribution, assignments, timesheets, invoices, and compliance documentation through the life of the engagement.
How do you handle validation expectations for the platform?
A VMS is typically a business system rather than a GxP-regulated one, but where it holds records supporting regulated activities, we work with your quality and IT teams to determine the appropriate assessment and documentation approach under your existing computer system validation policy.
Who administers the system after go-live?
Either your program team, our team, or a shared arrangement. We document the configuration and administration procedures either way, so administration can be handed over instead of living with one person.
