Introduction
If you're a staffing supplier or consultancy active on a Vendor Management System (VMS) platform, you already know the competition is real. Dozens of suppliers can see the same request. The client has limited time to evaluate proposals. And feedback is often minimal.
So what separates the suppliers who consistently win from those who respond to everything and hear nothing back?
At Connecting-Expertise, we've tracked what drives success for the suppliers on our platform. The patterns are clear. And they're not what most people assume.
What Is a VMS Platform and Why Does It Change How You Should Operate?
A Vendor Management System is a software platform that helps companies manage their external workforce: freelancers, interim workers, consultants, and the suppliers who provide them. Instead of managing dozens of supplier relationships by email or spreadsheet, companies use a VMS to centralise sourcing, contracting, timesheets, and payment in one place.
For suppliers, this changes the game. You're no longer competing purely on relationship. You're competing on responsiveness, quality of proposals, and platform presence. The clients evaluating you often don't know you. They see your proposal, your profile, and your price. That's it.
Understanding this is the starting point for everything else.

The Platform Structure: A Quick
Reference
For those newer to Connecting-Expertise, here's how the four main modules connect.
Source is where clients publish requests, either to a preferred supplier list or to the open marketplace. Suppliers respond with proposals.
Contracts handles the contracting process once a proposal is selected. Suppliers can participate in approval flows directly from the platform.
Track is the timesheet module. For clients using it, contractors log hours here, and suppliers can view and manage timesheets from their side.
Pay manages financial documents. Some clients use self-billing, where CE generates invoices on your behalf. Others require you to submit your own invoice outside the platform.
1. Speed Is a Competitive Advantage, But Not the Way You Think
Data from the Connecting-Expertise platform shows that 80% of selected proposals are submitted within 48 hours of a request being published. That's not a coincidence. Clients have a deadline to fill. Early submissions get more attention. Latecomers are often already irrelevant.
But speed without quality is counterproductive. What the best suppliers actually have is readiness. They can move fast because they've done the preparation in advance. Their talent pool is well-documented. They know who's available, what skills they have, and where they're willing to work. Their internal systems are organised, so there's no manual searching through spreadsheets when a new request comes in. And they've set up the platform correctly so notifications reach the right people immediately.
If you're currently losing 24 hours just to figure out who to propose, that's a process problem, not a talent problem. Fix the process, and speed follows naturally.
Practical tip: Use the Human Resources feature in Connecting-Expertise to build a structured candidate list directly in the platform. Once a profile is created, you can reuse it across multiple proposals without re-entering data. It also prepares you for upcoming AI matching features, more on that below.
2. Be Selective: Fewer, Better Proposals Win
One of the most common mistakes suppliers make is submitting as many candidates as possible, hoping something sticks. It doesn't work. It actually signals to clients that you haven't thought carefully about their request.
The suppliers who win most frequently submit two or three highly relevant candidates, with a clear rationale for each. They've read the brief carefully. They understand what the client is actually looking for. And they've matched their best fits accordingly.
This requires knowing your talent well. Not just their CVs, but their ambitions, their strengths, and the types of environments they thrive in. The suppliers with strong internal talent management consistently outperform those who treat their database as a searchable spreadsheet.
If your current tools make this hard, the Connecting-Expertise API allows you to connect your existing ATS or internal systems directly to the platform, eliminating the manual step of re-entering candidate data for every proposal. If you're spending significant time on data re-entry, this is worth exploring.
